This draft is a work item of the Content Delivery Networks Interconnection Working Group of the IETF. Title : CDNI Request Routing: Footprint and Capabilities Semantics Authors : Jan Seedorf Jon Peterson Stefano Previdi Ray van Brandenburg Kevin J. Ma Filename : draft-ietf-cdni-footprint-capabilities-semantics-05.txt Pages : 21 Date : 2015-03-03 Abstract: This document tries to capture the semantics of the "Footprint and Capabilities Advertisement" part of the CDNI Request Routing interface, i.e., the desired meaning of "Footprint" and "Capabilities" in the CDNI context, and what the "Footprint and Capabilities Advertisement Interface (FCI)" is expected to offer within CDNI. The document also provides guidelines for a CDNI FCI protocol. It further defines a Base Advertisement Object, the necessary registries for capabilities and footprints, and guidelines how these registries may be extended in the future. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-cdni-footprint-capabilities-semantics/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-cdni-footprint-capabilities-semantics-05 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-cdni-footprint-capabilities-semantics-05 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

S= orry for taking holidays just before the IETF, I didn't get around to this = doing this earlier. Hope it helps in taking us closer to WGLC. FCI Semantics, draft-ietf-cdni-footprint-capabilities-semantics-02 ---------------------------------------------------------------------------= ---- The purpose of the draft is to define the type of information a dCDN advert= ises regarding its footprint and capabilities. It states that "it is explic= itly outside the scope of this document to decide on specific protocols to = use for the FCI." It relies on the basic assumption that a bootstrapping pr= ocess has already been done between the uCDN and the set of dCDNs that are = interconnecting. Also, it assumes that footprint and capabilities need not = use the same protocol and that the uCDN directly receives the initial reque= st-routing request from the endpoint demanding the resource. Section 2: Design Decisions for Footprint and Capabilities Emphasizes the need to understand the definition of footprint in terms of "= coverage" and "reachability." The draft also mentions that global CDNs can = have global reachability (through IP connectivity) but CDNs with a more lim= ited coverage are suitable for the CDNi use cases. It states that "capabili= ties with footprint" versus "footprint with capabilities" semantics should = be adapted to the respective use case. 1) Advertising Limited Coverage There is an example of two regional ISPs that both have CDNs : one CDN belo= ngs to the ISP of the customer E (making the content demand) and the other = is the CDN that can offer better coverage to the customer E. Which CDN shou= ld serve the request still remains a dilemma. Same interrogation is valid f= or overlapping footprints advertised by several dCDNS. To answer the dilemma above, a "score" notion is introduced in order to be = able to rank the quality of the dCDN's service, preferably on the same scal= e. The conclusion is that coverage need not be binary. 2) Capabilities and Dynamic Data When footprints overlap, a uCDN might want to evaluate some extra merits of= the competing dCDNs. These criteria include state of the caches, network q= uality and policies, bandwidth etc. that can be highly volatile parameters. 3) Advertisement versus Queries Scalability issues may arise if the volume of FCI updates exceeds the volum= e of content requests to the uCDN. The advantage of a model based on synchr= onous queries is that the uCDN can operate in a stateless way (doesn't need= to keep track of dCDNs status). Choice to be made on a per use case basis. 4) Avoiding or Handling "cheating" dCDNs It's desirable to have a way for the uCDN to qualitatively verify the FCI i= nfo advertised by the dCDNs. Possibly non-real-time out-of-band audits. 5) Focus on Main Use Cases May Simplify Things To narrow down FCI semantics, might be better to pick some real life deploy= ments and tailor according to that. Section 3: Main Use Case to Consider Asks questions about practicalities in a simplified use case: uCDN has two = dCDNs out of which one has another level-2 dCDN. How does the uCDN take int= o account failures/changes of the level-2 dCDN? How does uCDN handle subset= s of the footprint initially served by one of its dCDNs? Section 4: Semantics for Footprint Advertisement Roughly, footprint =3D ability and willingness to serve. How well a dCDN ca= n serve requests is another piece of information that could be added to the= footprint, but will be mostly associated to contractual agreements. Assuming that the initial footprint is established in the contract, FCI pro= vides changes and updates to the previously agreed footprint. The draft fur= ther considers two types of footprint: coverage/reachability (3 types manda= tory to support by FCI: set of IP prefixes, list of AS numbers, country ISO= codes) and resources (location of the surrogates). Section 5: Semantics for Capabilities Advertisement In certain cases, footprint and capabilities cannot be interpreted separate= ly: need to associate the coverage of a geographical region with a certain = delivery protocol. In such cases, it should be possible to combine footprin= t and capabilities advertisements. Advertisement of highly dynamic capabilities is out of scope. Just like for= the footprint, the capabilities advertisement refers to conveying informat= ion to a uCDN about changes/updates with respect to a given contract. Defined "base" capabilities: o Delivery Protocol (HTTP, RTMP) o Acquisition Protocol o Redirection Mode (DNS, HTTP) o Capabilities related to CDNI Logging o Capabilities related to CDNI Metadata The FCI spec should define a generic protocol for sending this type of info= rmation and should allow for the list above to be further expanded if neede= d. 6. Negotiation of Support for Optional Types of Footprint/Capabilities Need to specify the behavior of CDNs that do not support the optional types= of footprint/capabilities : how to react in case of failure? The uCDN can = ignore or select dCDN based only on the parameters it understands. 7. IANA Considerations Requires a new IANA registry "CDNI Capabilities"; this namespace should be = split into standard (for Mandatory To Implement) and optional. A table prov= ides the initial standard partition: Delivery Protocol, Acquisition Protoco= l and Redirection Mode. The optional partition conforms to Expert Review po= licy. No IANA action required for the defined Footprint Sub-Registry or the Proto= col Sub-Registry. A table defines the initial Redirection Modes: Iterative = DNS, Recursive DNS, Iterative HTTP, Recursive HTTP. 8. Security Considerations This section still needs to be done, as there is not much text. Comments: The main purpose of the draft is to say what people understand when they sa= y footprint or capabilities. It does a pretty good job at narrowing down th= e concepts and explaining the implications of the wider notions. There are = several examples provided regarding the basic set we should be considering = in CDNI. I think the draft needs a bit more work in the following points: 1.

Subject: [CDNi] [CDNI] FCI analysis

 

Hello C= DNI fellows,

 <= o:p>

[It see= ms I missed posting this directly to the working group mailing list, so the= re it is now]

 

Here go= es the analysis of the Footprint and Capabilities semantics draft. Sorry fo= r taking holidays just before the IETF, I didn’t get around to this d= oing this earlier. Hope it helps in taking us closer to WGLC.

 <= /span>

FCI Sem= antics, draft-ietf-cdni-footprint-capabilities-semantics-02

-------= ------------------------------------------------------------------------

 <= /span>

The pur= pose of the draft is to define the type of information a dCDN advertises re= garding its footprint and capabilities. It states that “it is explici= tly outside the scope of this document to decide on specific protocols to use for the FCI.” It relies on the basic as= sumption that a bootstrapping process has already been done between the uCD= N and the set of dCDNs that are interconnecting. Also, it assumes that foot= print and capabilities need not use the same protocol and that the uCDN directly receives the initial request-rout= ing request from the endpoint demanding the resource.

Section= 2: Design Decisions for Footprint and Capabilities

Emphasi= zes the need to understand the definition of footprint in terms of “c= overage” and “reachability.” The draft also mentions that= global CDNs can have global reachability (through IP connectivity) but CDNs with a more limited coverage are suitable for the CDNi use cases.= It states that “capabilities with footprint” versus “foo= tprint with capabilities” semantics should be adapted to the respecti= ve use case.

 <= o:p>

1)Advertising Limited Cov= erage

There i= s an example of two regional ISPs that both have CDNs : one CDN belongs to = the ISP of the customer E (making the content demand) and the other is the = CDN that can offer better coverage to the customer E. Which CDN should serve the request still remains a dilemma= . Same interrogation is valid for overlapping footprints advertised by seve= ral dCDNS.

To answ= er the dilemma above, a “score” notion is introduced in order t= o be able to rank the quality of the dCDN’s service, preferably on th= e same scale. The conclusion is that coverage need not be binary.=

2)Capabilities and Dynami= c Data

When fo= otprints overlap, a uCDN might want to evaluate some extra merits of the co= mpeting dCDNs. These criteria include state of the caches, network quality = and policies, bandwidth etc. that can be highly volatile parameters.

 <= o:p>

3)Advertisement versus Qu= eries

Scalabi= lity issues may arise if the volume of FCI updates exceeds the volume of co= ntent requests to the uCDN. The advantage of a model based on synchronous q= ueries is that the uCDN can operate in a stateless way (doesn’t need to keep track of dCDNs status). Choice= to be made on a per use case basis.

 <= o:p>

4)Avoiding or Handling &#= 8220;cheating” dCDNs=

It̵= 7;s desirable to have a way for the uCDN to qualitatively verify the FCI in= fo advertised by the dCDNs. Possibly non-real-time out-of-band audits.

 <= /span>

5)      Focus on Main Use Cases= May Simplify Things

To narr= ow down FCI semantics, might be better to pick some real life deployments a= nd tailor according to that.

 <= /span>

Section= 3: Main Use Case to Consider=

Asks qu= estions about practicalities in a simplified use case: uCDN has two dCDNs o= ut of which one has another level-2 dCDN. How does the uCDN take into accou= nt failures/changes of the level-2 dCDN? How does uCDN handle subsets of the footprint initially served by one of i= ts dCDNs?

 <= /span>

Section= 4: Semantics for Footprint Advertisement

Roughly= , footprint =3D ability and willingness to serve. How well a dCDN can serve= requests is another piece of information that could be added to the footpr= int, but will be mostly associated to contractual agreements.

Assumin= g that the initial footprint is established in the contract, FCI provides c= hanges and updates to the previously agreed footprint. The draft further co= nsiders two types of footprint: coverage/reachability (3 types mandatory to support by FCI: set of IP prefixes, list of AS numbe= rs, country ISO codes) and resources (location of the surrogates).

 <= /span>

Section= 5: Semantics for Capabilities Advertisement<= /o:p>

In cert= ain cases, footprint and capabilities cannot be interpreted separately: nee= d to associate the coverage of a geographical region with a certain deliver= y protocol. In such cases, it should be possible to combine footprint and capabilities advertisements.

Adverti= sement of highly dynamic capabilities is out of scope. Just like for the fo= otprint, the capabilities advertisement refers to conveying information to = a uCDN about changes/updates with respect to a given contract.

Defined= “base” capabilities:

 &= nbsp;           &nbs= p;  o Delivery Protocol (HTTP, RTMP)<= /o:p>

 &= nbsp;           &nbs= p;  o Acquisition Protocol

 &nbs= p;            &= nbsp; o Redirection Mode (DNS, HTTP)

 &nbs= p;            &= nbsp; o Capabilities related to CDNI= Logging

 &= nbsp;           &nbs= p;  o Capabilities related to CDNI Metadata

The FCI= spec should define a generic protocol for sending this type of information= and should allow for the list above to be further expanded if needed.

Actually, In several aspects the new text is actually weaker:

- The old text said “MUST support TLS_DHE_RSA_WITH_AES_128_GCM_SHA256” while the new does not mandate support of any cipher suites without known weaknesses.

- “MUST support TLS_DHE_RSA_WITH_AES_128_GCM_SHA256” implied “MUST support TLS 1.2” while the new text only implies “SHOULD support TLS 1.2”.

I think supporting TLS 1.2 and a cipher suite without weaknesses should be mandated.


And while the TLS BCP is great for general guidance, it is alone not a good profile for a new standard. It heavily takes interop with legacy endpoints into account and does e.g. not forbid weak TLS sessions like: TLS 1.0 with 3DES_CBC, TLS compression, RSA-768 keys, and 768-bit Diffie-Hellman groups.


As CDNi is a new standard is there a reason to not be stricter? I would suggest:

“The general TLS usage guidance in [I-D.draft-ietf-httpbis-http2, Section 9.2] MUST be followed.”

Cheers,
John

Folks,

Consistently with John’s comment below, we received similar comments as part of the IESG review of cdni-logging that we should refer to the TLS BCP being finalised by the UTA Working Group, instead of making up our own recommendations. This makes tons of sense of course, as we were only making our own recommendations because we were not aware of this BCP.

So, for cdni-logging, I’ve proposed to the IESG that we make the following specific edits:

OLD:
“
   An implementation of the CDNI Logging interface MUST support the
   TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 cipher suite ( [RFC5288]).  An
   implementation of the CDNI Logging interface SHOULD prefer cipher
   suites which support perfect forward secrecy over cipher suites that
   don't.
"
NEW:
"
 The general TLS usage guidance in [I-D.ietf-uta-tls-bcp] SHOULD be
   followed.
“

Let us know if you have any comment or concern with that, so we can make a generic decision that would apply (by default) to all CDNI interfaces.


Cheers

Francois

- This is not enough to make sure that the implementation is secure. At a bare minimum the list should be enhanced with:
* The general TLS usage guidance in [TLSBCP] SHOULD be followed
The cipher suite is only one part and there is still many ways to end up with something insecure.

- As TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 requires TLS 1.2, the text "TLS MUST be implemented”, could as well be changed to “TLS 1.2 MUST be implemented”. And as TLS 1.2 MUST be implemented there is no reason to use TLS 1.0 or 1.1. The list could therefore say.
* TLS 1.2 MUST be implemented 
* Implementations that use TLS, MUST use TLS 1.2 or higher.

- As this is a new standard/deployment, it can be even stricter than the TLSBCP (which takes legacy implementations into account). The HTTP/2 specification (draft-ietf-httpbis-http2-17), Section 9.2, is a good example of how a TLS profile for a new deployment can be designed, It could maybe be used for guidance, alternatively referred to as the TLS profile also for CDNI.

John

As CDNi is a new standard is there a re= ason to not be stricter? I would suggest:

=E2=80=9CThe gener= al TLS usage guidance in [I-D.draft-ietf-httpbis-http2, Section 9.2] MUST be= followed.=E2=80=9D

So, for cdni-logging, I=E2=80=99ve proposed to the IESG that= we make the following specific edits:

OLD:
=E2=80=9C
   An imp= lementation of the CDNI Logging interface MUST support the
   TLS_DH= E_RSA_WITH_AES_128_GCM_SHA256 cipher suite ( [RFC5288]).  An

"
NEW:
"
 The general T= LS usage guidance in [I-D.ietf-uta-tls-bcp] SHOULD be
   follow= ed.
=E2=80=9C

Let us know if you have any comment or concern with that, so= we can make a generic decision that would apply (by default) to all CDNI in= terfaces.

- This is not enough t= o make sure that the implementation is secure. At a bare minimum the list sh= ould be enhanced with:
* The general TLS usage guidance in [TLSBCP] SHOULD be followed
The cipher suite is on= ly one part and there is still many ways to end up with something insecure.<= /font>

- As TLS_DHE_RSA_WITH_AES_128_G=
CM_SHA256 requires TLS 1.2, the=
 text "TLS MUST be implemented=E2=80=9D, could as well be changed to =E2=80=9C=
TLS 1.2 MUST be implemented=E2=80=9D. And as TLS 1.2 MUST be implemented there is no reaso=
n to use TLS 1.0 or 1.1. The list could therefore say.
* TLS=
 1.2 MUST be implemented 
* Impl=
ementations that use TLS, MUST use TLS 1.2 or higher.

- As this is a new standar=
d/deployment, it can be even stricter than the TLSBCP (which takes legacy im=
plementations into account). The HTTP/2 specification (draft-ietf-httpbis-ht=

This draft is a work item of the Content Delivery Networks Interconnection Working Group of the IETF. Title : CDNI Request Routing: Footprint and Capabilities Semantics Authors : Jan Seedorf Jon Peterson Stefano Previdi Ray van Brandenburg Kevin J. Ma Filename : draft-ietf-cdni-footprint-capabilities-semantics-06.txt Pages : 20 Date : 2015-03-09 Abstract: This document tries to capture the semantics of the "Footprint and Capabilities Advertisement" part of the CDNI Request Routing interface, i.e., the desired meaning of "Footprint" and "Capabilities" in the CDNI context, and what the "Footprint and Capabilities Advertisement Interface (FCI)" is expected to offer within CDNI. The document also provides guidelines for a CDNI FCI protocol.

If you = have read the CDNI agenda posted today, you might be wondering what the las= t topic is all about. Indeed, I have given some attention to the HTTPS surg= e that we’ve been lately seeing on the network and it occurred to me that this is something to be discussed withi= n the CDNI working group. So far, the group has been concentrating only on = delivery of HTTP traffic in the clear, so the reasonable action seemed to b= ring up HTTPS and discuss it in Dallas.

There a= re a few ideas that I’d like us to debate and they revolve around the= following:

= 1.       Is this the right working group to tackle HTTPS in interconnected CDNs? (t= here are a lot of hallway conversations going on and some other working gro= ups might want to be involved)

= 2.       What are the technical ways to achieve this? A few methods are known in th= e industry, maybe we could start by doing an inventory of what is available= ? Is it possible to rely on the existing CDNI interfaces and expand them to support delegation of HTTPS content (Me= tadata comes to mind)?

It should be possible to support = delegation of HTTPS content using extensions to the existing CDNI = interfaces. A while ago Mal, Rob & I wrote a draft[1] illustrating how the metadata = interface (as it was defined at the time) could be extended to support = HTTPS. Our motivation was to see if extending the metadata interface = with new metadata was feasible as a "test" so the draft is not complete, = for example it does not secure the private keys in any way. We took the simple approach of distributing the necessary metadata & = keys but depending on the content provider's and uCDN's appetite for = sharing private keys with dCDNs, an approach that used Keyless SSL[2] = and distributed the metadata required for that might be more = appropriate. Depending on the type of redirection required the redirection interface = may need extending as well, e.g. by defining a https dictionary that is = similar/identical to the existing http dictionary, although I suspect = most uses of HTTPS would use DNS redirection. Other are probably better placed to comment on any impacts to the other = CDNI interfaces.

All dCDNs could decrypt the token contents (they are in the clear today) = using public keys but only the generator of the token could create a = token and there are no issues of sharing shared secrets between CDNs?

I am actually coordinat= ing the effort from MPEG concerning the use of URI Signing, and its possibl= e improvements, in MPEG DASH. If I may comment on your remark : " Tokens were originally used to avoid p= eople being able to download large files they couldn't play or install, etc= . that the content provider had to pay for. They're not a substitute for DR= M'ing content to prevent unauthorised playout." Today in MPEG, people are also working on methods to enable playback contr= ol of DASH clients. Needless to say that the non-normative nature of DASH c= lient behaviors makes difficult to enforce such a control from the client s= ide. However, one way to control what a DASH client may or may not playback= is to control the delivery of the segments in the first the place. Hence b= eing sure that a specific content is not going to be played out. And this d= ecision can be motivated by business rules or any other context. So using D= RM for that purpose wouldn't be appropriate because the client has the righ= t to watch the content (e.g. he paid for it) but he just needs to perform c= ertain actions first in order to retrieve the content (e.g. retrieve an ad)= .=20 Regards, Emmanuel=20 -----Original Message----- From: CDNi [mailto:cdni-bounces@ietf.org] On Behalf Of Ben Niven-Jenkins Sent: woensdag 25 maart 2015 23:58 To: Brandenburg, R.

Hi Ben,

The chained tokens I don't see how they ad= d material benefit over a token with a long expiry time. If someone can sha= re a manifest, they can share a URL for a video segment.

The latter part of your argument, the fact that it is quite easy to sh= are a URL, is exactly the reason why a token with a long expiry time doesn'= t work. 

It is a lot easier to share a URL with a validity time of 90 minutes t= han one that is only valid for 10 seconds. To be honest I don't see any ben= efit of using any token or signed URI if it is going to have a long expirat= ion time (in the order of minutes or more). 

They're not a substitute for DRM'ing conte= nt to prevent unauthorised playout.

Completely agree.

That's why we have DRM. Access tokens are about download, not playou= t. (And of course using access tokens as DRM is impractical: short expirat= ions fail when you support pause/rewind or even simple network delays; long= tokens do not prevent reply; client addresses are inaccurate for shared de= vices and NAT'd networks; etc.) When you say "business rules," are you talking about the content provider= , or the CDN provider? CDN providers may want to use tokenized URLs to pre= vent bandwidth denial of service attacks (though it may arguably make reque= st router denial of service attacks easier), but content providers can't re= asonably rely on tokenized URLs to enforce licensing agreements, imo. To Ben's point, access tokens protect the CDN provider, and in turn the c= ontent providers who pay the CDN providers, from unnecessary delivery costs= . Access tokens do not provide DRM or reasonable playout control against = (un)licensed viewers. thanx. -- Kevin J.

That's why we have DRM. Access tokens are about download, not playou= t. (And of course using access tokens as DRM is impractical: short expirat= ions fail when you support pause/rewind or even simple network delays; long= tokens do not prevent reply; client addresses are inaccurate for shared de= vices and NAT'd networks; etc.) When you say "business rules," are you talking about the content provider= , or the CDN provider? CDN providers may want to use tokenized URLs to pre= vent bandwidth denial of service attacks (though it may arguably make reque= st router denial of service attacks easier), but content providers can't re= asonably rely on tokenized URLs to enforce licensing agreements, imo. To Ben's point, access tokens protect the CDN provider, and in turn the c= ontent providers who pay the CDN providers, from unnecessary delivery costs= .

Abstract:
  This document describes how the concept of URI signing su= pports the
  content access control requirements of CDNI and proposes = a URI
  signing scheme.

  The proposed URI signing method specifies the information= needed to
  be included in the URI and the algorithm used to authoriz= e and to
  validate access requests for the content referenced by th= e URI.  Some
  of the information may be accessed by the CDN via configu= ration or
  CDNI metadata.
