Adopting requirements draft as CDNI WG document X-BeenThere: cdni@ietf.org X-Mailman-Version: 2.1.12 Precedence: list List-Id: "This list is to discuss issues associated with the Interconnection of Content Delivery Networks \(CDNs\)" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 07 Sep 2011 12:26:02 -0000 Hello, No objection have been raised so draft-lefaucheur-cdni-requirements-02 = is now considered accepted as WG document. Zhipeng suggested that a note be included along the lines of "the draft = is not yet finished and other requirements may still be included." While = this is somewhat redundant since a WG document is inherently candidate = for change, this does not really hurt and avoids the risk that external = standards forum tracking this work mis-interpret the status of that = document.

This draft is a work item of the Content Delivery Networks Interconnec= tion Working Group of the IETF. Title : Content Distribution Network Interconnection (CDNI) Prob= lem Statement Author(s) : Ben Niven-Jenkins Francois Le Faucheur Nabil Bitar Filename : draft-ietf-cdni-problem-statement-00.txt Pages : 37 Date : 2011-09-09 Content Delivery Networks (CDNs) provide numerous benefits: reduced delivery cost for cacheable content, improved quality of experience for End Users and increased robustness of delivery. For these reasons they are frequently used for large-scale content delivery. As a result, existing CDN providers are scaling up their infrastructure and many Network Service Providers (NSPs) are deploying their own CDNs. It is generally desirable that a given content item can be delivered to an End User regardless of that End User's location or attachment network. This creates a requirement for interconnecting standalone CDNs so they can interoperate as an open content delivery infrastructure for the end-to-end delivery of content from Content Service Providers (CSPs) to End Users. However, no standards or open specifications currently exist to facilitate such CDN interconnection. The goal of this document is to outline the problem area of CDN interconnection (CDNI) for the IETF.

This draft is a work item of the Content Delivery Networks Interconnec= tion Working Group of the IETF. Title : Content Distribution Network Interconnection (CDNI) Requ= irements Author(s) : Kent Leung Yiu Lee Filename : draft-ietf-cdni-requirements-00.txt Pages : 20 Date : 2011-09-09 Content Delivery Networks (CDNs) are frequently used for large-scale content delivery. As a result, existing CDN providers are scaling up their infrastructure and many Network Service Providers (NSPs) are deploying their own CDNs. There is a requirement for interconnecting standalone CDNs so that their collective CDN footprint can be leveraged for the end-to-end delivery of content from Content Service Providers (CSPs) to end users. The Content Distribution Network Interconnection (CDNI) working group has been chartered to develop an interoperable and scalable solution for such CDN interconnection. The goal of the present document is to outline the requirements for the solution and interfaces to be specified by the CDNI working group. This draft is a work in progress and requirements may be added, modified, or removed by the working group. Requirements Language The key words "High Priority", "Medium Priority" and= "Low Priority" in this document are to be interpreted in the following way: o "High Priority" indicates requirements that are to be suppo= rted by the CDNI interfaces. A requirement is stated as "High Priority&= quot; when it is established by the working group that it can be met without compromising the targeted schedule for WG deliverables, or when it is established that specifying a solution without meeting this requirement would not make sense and would justify re- adjusting the WG schedule, or both. This is tagged as "[HIGH]&q= uot;. o "Medium Priority" indicates requirements that are to be sup= ported by the CDNI interfaces unless the WG realizes at a later stage that attempting to meet this requirement would compromise the overall WG schedule (for example it would involve complexities that would result in significantly delaying the deliverables).

Delivery Networks \(CDNs\)" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 12 Sep 2011 22:55:54 -0000 A couple of comments on this draft: - Should R27 be under Section 4 rather than 5? - I think R28 should be a MUST, and it should be written in the context of=8A"The Upstream CDN MUST request aggregate information from the Downstream CDN to facilitate=8A" If it's not a request, then it must go th= e other way (the Downstream CDN MUST report to the Upstream CDN). - In addition, I think R28 should really be part of the control protocol. This information should be known prior to initiating a Route Request. - Under the control protocol requirements, there is no requirement as to how often this should occur. - Should R30 also be under Section 4 rather than 5? - R35 - I did not see a requirement for "loop detection". Did I miss it? I see what looks like a requirement in R42. If this is the case, it should be broken out and placed in section 4. - R44 - Again, this looks like a requirement for loop prevention, but there is still no hard requirement saying "there MUST be a loop prevention mechanism!" Note: it would be good to group like requirements for clarity. - Section 6 - Is this intended to be a protocol within the control protocol? To me it looks like it should. Another way to ask it is, can this be included within the control protocol? - R59 - Should it also include "alternative content" sources, options, etc. in the case of "blackouts"? - Section 7 - Should there be a "quality" metric or respond from the downstream CDN on the delivered content to the End user? With regards to cascaded CDNs, this could be very bad. I think there must be a control mechanism to indicate how many "cascades" are involved in the CDNI and allow the Upstream CDN to cut it off at some point. Also, should there be any mechanism to indicate whether entitlements are an issue to downstream CDNs from the CSP?

Rather, a smaller set of properties are proposed. These should be sufficient to implement a minimal interconnect of basic HTTP delivery. Readers are encouraged to focus on the overall structure of the protocol rather than on the details or omission of particular properties. Additional properties may be added in future drafts or may be better placed in separate documents that focus on the CDNI Metadata required to interconnect delivery of individual end-user protocols. I was hoping this type of draft would begin to answer questions that are raised by statements in the framework draft, such as "Request Router for Operator A processes the DNS request for CDN-domain cdn.csp.com and recognizes that the end-user is best served by another CDN." What in the metadata indicates to Operator A that the end-user is best served by another CDN, and more importantly which Downstream CDN? While, this draft is a good start, I'm anxious to get into the meet of what is exchanged and how it will help the upstream CDN make good decisions about the varying downstream CDNs could possibly better serve the end user.

This information should be known prior to initiating a Route Request. - Under the control protocol requirements, there is no requirement as to how often this should occur. - Should R30 also be under Section 4 rather than 5? - R35 - I did not see a requirement for "loop detection". Did I miss = it? I see what looks like a requirement in R42. If this is the case, it should be broken out and placed in section 4. - R44 - Again, this looks like a requirement for loop prevention, but there is still no hard requirement saying "there MUST be a loop = prevention mechanism!" Note: it would be good to group like requirements for = clarity. - Section 6 - Is this intended to be a protocol within the control protocol? To me it looks like it should. Another way to ask it is, can this be included within the control protocol? - R59 - Should it also include "alternative content" sources, options, etc. in the case of "blackouts"? - Section 7 - Should there be a "quality" metric or respond from the downstream CDN on the delivered content to the End user? With regards to cascaded CDNs, this could be very bad. I think there = must be a control mechanism to indicate how many "cascades" are involved in = the CDNI and allow the Upstream CDN to cut it off at some point. Also, should there be any mechanism to indicate whether entitlements are an issue to downstream CDNs from the CSP?

I also updated my comment on loop detection/prevention. This is now a requirement under GEN-11. I did notice some amount of potential redundancy left over in other requirements though. I just ask the authors to review all references to Loop Detection/Prevention and see if a simply reference to GEN-11 will suffice. Let me know if you have any other questions.

I think you may be confusing the scope of CDNI Metadata with other = components in a CDNI solution (or the existing documents do not explain = the distinctions/boundaries well enough). CDNI Metadata flows from the = upstream CDN to the downstream CDN and the CDNI Metadata interface is = the mechanism for communicating the CDNI Metadata. The CDNI Metadata is = how the Upstream CDN tells the Downstream CDN how to deliver the = content. In order for an Upstream CDN to be able to select an appropriate = Downstream CDN the Upstream CDN needs to be aware of the capabilities of = the Downstream CDN which may be advertised in some fashion or = configured/communicated out of band (e.g. through some business process = such as a contract). Discussion/specification of how to do that = advertisement is in scope of CDNI but the actual mechanism an upstream = CDN uses to make the final decision is out of scope of the WG and is = implementation specific. While CDN capability advertisement is in scope of CDNI it is not IMO a = function of the CDNI Metadata interface as it is not directly related to = how a Downstream CDN must deliver content. > While, this draft is a good start, I'm anxious to get into the meet of > what is exchanged and how it will help the upstream CDN make good > decisions about the varying downstream CDNs could possibly better = serve > the end user. That's a good discussion that the group needs to have and I have some = initial ideas for how it could be done that I haven't had the chance to = put on paper yet but the place for that discussion is not in the scope = of the CDNI metadata interface IMO for the reasons I give above. Communicating capabilities from a Downstream CDN to an Upstream CDN and = the specific properties for how to deliver some content that need to be = communicated by an Upstream CDN to a Downstream CDN are obviously = related. However, the statement that you quote above is meant to convey = that for CDNI Metadata, let us first agree that the proposed data model = in the draft and the structure of the proposed interface are (or are = not) the right starting points for describing how a CDN should deliver = content and for communicating/distributing that CDNI Metadata from an = Upstream CDN to a Downstream CDN rather than risking going off on a = tangent with comments such as "you haven't included a property to allow = an Upstream CDN to indicate that a piece of content should be delivered = no faster than X Mbps" etc. because adding/describing new properties to = convey different ways to deliver content is trivial compared to making = sure we have a solid foundation for the CDNI Metadata Model & interface = on which to overlay such properties.

Hello Ben,=

Via readin= g the web of your company, http://www.velocix.com/deli= very.php

 = ;

I find an = interesting feature: =A1=B0Delivery speed contr= ol=A1=B1.

In my unde= rstanding, that is a kind of service with Quality Priority.

 = ;

Meanwhile,= in the whitepaper http://= www.velocix.com/next_gen_video_distr_velocix.pdf

The section = 3.3 =A1=B0Flexibl= e and Multi-level Quality Control=A1=B1 also has some descript= ion such as =A1=B0intelligent traffic management=A1=B1.

 <= /o:p>

So, I feel s= uch technology has already been implemented in your company=A1=AFs product.=

 <= /o:p>

Then, if to = support such capability in the CDN-CDN scenario, perhaps some simple negoti= ation would be needed based on the existing CDN capability.

So, I feel m= y use cases looks appropriate and I am wondering whether you may help me wi= th some more  explanations.

Thanks very = much.

Hi Ben,

Rich,

One correction related to something I said during the meeting

Towards the bottom of the minutes:

Ben Niven-Jenkins: Layer 4 VPNs= are a multi-billion dollar market. And they do

everything out of band.


Can you s/Layer 4/Layer 3/

 

Done.




Also as a clarification I didn't actually say that Layer 3 VPNs do *everyth= ing* out of band, what I said was that the negotiation for what treatment t= o apply for a particular CoS/DSCP value (or how to map a particular DSCP va= lue in one network to a different DSCP value in another network) is performed out of band between Layer 3 VP= Ns running over interconnected network.

 

I checked back the audio record= ing and aligned the minutes to what was said. It now reads:

 

"

Ben Niven-Jenkins: We have an e= xistence proof: Layer 3 VPNs are a multi-billion dollar market today and th= ey do all of this out of band. 

 

Francois Le Faucheur: I challen= ge that assertion. They do most of it out of band, but they still use an in= -band signaling mechanism (DSCP) to invoke the differentiated services.&nbs= p;

 

Ben: OK, but the mapping of DSC= P across operators and its meaning is out of band.

 

Francois Le Faucheur: yes, but = that part I am hoping we all agree is out of scope.

"

 

 

Francois

 

PS: The new minutes are not yet= accessible on line as the meeting material page is not letting me upload t= hem (working on it with datatracker folks).

 



The rest of the minutes look OK= to me.

Thanks
Ben

I'll expand on the analogy I drew in the meeting. Many router products = support the configuration of different packet classification, marking, = shaping and queuing strategies but in Layer 3 VPNs the treatment of = different classes of traffic is not signalled through the control plane = but rather the mapping between how certain traffic is classified by = different VPN providers that have interconnected their networks is = 'signalled' out of band via business agreements between the VPN = providers. One of the reasons for that is that the appropriate classification and = treatment within a network is dependent on how that network has been = built/designed and trying to have some generic language for describing = it and mapping between different variants rapidly gets very complicated = and is not something that can necessarily be done automatically. Let's not forget that CDNs won't interconnect without some business = agreement occurring between the two interconnected CDNs and as part of = that business agreement certain classifications/mappings can be made = without trying to build complexity into the CDNI interfaces themselves, = especially for properties such as "Quality Control" where the actual = meaning/treatment is likely to be dependent on the specific network = design/deployment and any kind of automatic negotiation is likely to be = anything but simple due to the differences in the CDN products used and = the way the networks have been designed/deployed. IMO the CDNI interfaces (for example the CDNI Metadata interface) need = the ability to carry properties that indicate that some content should = be treated differently to other content but how that property is mapped = to how that content is treated by the individual CDNs is something that = does not need to be negotiated at "run time" and that it is probably not = possible to do an automatic negotiation/mapping anyway without the = mapping being done out of band via some business agreement. Instead it is probably sufficient for two interconnected CDNs to have a = common understanding (that is acceptable to both parties and their = customers) via a business agreement about how to map such properties = onto their own CDNs/networks according to how they have = designed/deployed those CDNs/networks. Such an approach works for Layer = 3 VPNs todays which are a multi-billion dollar market without requiring = complex (and ultimately IMO futile) automatic negotiation protocol = machinery.

This draft is a work item of the Content Delivery Networks Interconnec= tion Working Group of the IETF. Title : Use Cases for Content Delivery Network Interconnection Author(s) : Gilles Bertrand Stephan Emile Grant Watson Trevor Burbridge Philip Eardley Kevin Ma Filename : draft-ietf-cdni-use-cases-00.txt Pages : 17 Date : 2011-09-22 Content Delivery Networks (CDNs) are commonly used for improving the footprint and the end-user experience of a content delivery service, at a reasonable cost. This document outlines real world use-cases (not technical solutions) for interconnecting CDNs. It can be used to provide guidance to the CDNI WG about the interconnection arrangements to be supported and to validate the requirements of the various CDNI interfaces. This document describes a number of use cases that motivate CDN Interconnection. It represents a work in progress and may be extended later to cover additional use-cases.

Do all restrictions apply to all globs, or can individual restrictions be associated with individual globs? - The SelectionACL seems to suggest Surrogate selection restrictions, but is Surrogate information not intra-CDN information and outside the scope of CDNI? - The origin parameters seem HTTP specific? Should they be encapsulated based on an origin protocol? Would the origin protocol not be related to the DeliveryProtocol in some way?

The intent of this use case needs to be clarified. Perhaps the use case is trying to address the scenario where a Nomadic User-A with an agreement allowing access to content from CSP-A via uCDN moves to a dCDN in a different region. The dCDN is allowed to distribute the content of CSP-A to User-A; however, not other users in the region of the dCDN are allowed to retrieve the content unless they too have such an agreement. Section 5.1.3 Content Encoding Restrictions Need to clarify if we're talking about the restrictions on the delivery of specific content or the restrictions on the ability of a CDN to deliver specific content. I certainly understand the case where a CSP will restrict the distribution of content to a "managed path" if such content is HD while allowing the content distribution via an un-managed path if such content is SD (same could apply to encryption methods, delivery methods, etc.). On the contrary, the dCDN may have its own restrictions of blocking the distribution of HD content while allowing the distribution of SD content. o first bullet makes sense if the dCDN can perform a subset of encapsulations for a reference set of media (e.g. HLS, HSS, but not DASH) o second bullet makes sense where the dCDN doesn't want to offer high bit-rate variants of the media o third bullet make sense if the policy addresses QoE but I don't think subscriber rights/authorizations apply. Section 10 Security Considerations Aside from the security considerations WITHIN the uCDN and dCDN, I think we can describe this in four contexts: a. The relationship between the CSP and the uCDN (the principle contract arrangement for distribution) b. The relationship between the uCDN and dCDN (the transitive trust relationship that extends the contract defined in (a) above) c. The relationship between the User and dCDN (the recognition of right to download predicated on (b) above) d. The relationship between the User and CSP (the contract authorizing the user access to the content) The user is not interested in the a-b nor the b-c relationship. The user is only interested in the transparency and interoperability of the security relationship between d-b or d-c to the point that the authorization granted in d-a is viable when the delivery is initiated via either d-b or d-c. As an example, the uCDN might use URL appended tokens for authentication while dCDN might use URL appended hashes. The user doesn't want to know about the distinct methods, but transparency is only afforded if the methods are interoperable clearly defined when the delegation for content delivery is executed. Clearly, the choice of authentication method is determined by the respective CDN's.

I think the nomadic use case includes not only geographic extension, but more generically footprint extension. A carrier CDN with only an in-network presense for specific devices (e.g., mobile vs TV) may want to increase its device footprint by interconnecting with another local carrier CDN that supports other devices or subscribers. We are also looking at removing section 5.1.3. > As an example, the uCDN might use URL appended > tokens for authentication while dCDN might use URL appended hashes. ... > Clearly, the choice of > authentication method is determined by the respective CDN's. Content providers typically implement apps today with an understanding th= at the uCDN has a specific authentication method. If the uCDN delegates delivery to a dCDN that the content provider has no relationship with, th= e app may have no ability to switch authentication methods. Would the uCDN= be responsible for generating of the proper dCDN credentials for the user? thanx. -- Kevin J.
