One other unrelated thing: max bundle size is currently abut 2GB then it breaks. We had some msc students look at this a couple of years ago as a term assignment and they fixed it, but then they went and lost their code, graduated and buggered off;-) So its an easy fix and maybe related to this work, e.g. if you look at performance vs. bundle size then you might want to fix this.

hi...

i try to compare the wireshark = DTN delay and log DTN delay
i found in specific file size it has big dif= ference..
i think im doing wrong taken delay by wireshark..
anybody k= now how to measure delay and throughput through wireshark?
i cant find unique port like tcp protocol or any unique id to know where is= start and end of packet data transfer (cause the packet in wireshark mixed= by daemon communication) :D
thanks for response :D

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 07 May 2012 00:25:08 -0000 Dear Angela, I think your effort is very valuable when thinking about the applicability of DTN concepts to everyday scenarios. I say this because I have seen throughput results that show that DTN2 performance is lower than that of IBR-DTN. Moreover, in our experiments we noticed that dtnping performance in DTN2 is also significantly worse compared to IBR-DTN. In this context I think it would be useful if you could share more details about the following issues: 1) Exactly what kind of performance characteristics are you trying to improve? Is it throughput? 2) Have you already established a baseline you can compare your improvements to? If so, are these results published somewhere, or could they be made public? 3) Are you only looking at evaluating the performance in 2-node scenarios, or do you have larger setups in mind? Our experience using a network emulation testbed showed that in scenarios with many nodes things do break up for DTN2. We have only tried up to 25 nodes because of the bad results we've got (especially for dtnping), but larger experiments are possible. If you are interested, I could provide mroe details to you about our testbed and general approach (note that the results are not yet public).

dtncpd = frequently causes dtnd to crash on my RedHat machine. I'm running dtn = version 2.8.0.

I start dtnd as follows, logging at = debug level:

Then I start = dtncpd:

Initializing the database each = time I run dtnd seems like a rather draconian solution = though...

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 10 May 2012 09:57:59 -0000 Hi Tom, dtncpd is not causing dtnd to crash in this instance - the dtnd has not started in the first place due an error initializing the global store which appears to be the result of some corruption as the database was not cleanly shut down. The error 'in ipc communication' in this case occurs as there is no dtnd daemon running. The problem appears to fix itself when you run dtnd with the --init-db flag as this initializes the database All the best, Alex On Wed, 2012-05-09 at 17:32 -0700, Tom O'Reilly wrote: > dtncpd frequently causes dtnd to crash on my RedHat machine.

In general, when is it "necessary" to reinitialize the database with the --init-db flag? I assume when the network topology changes... how about other conditions?

In general, when is it "necessary" to = reinitialize the database with the --init-db flag?
I assume = when the network topology changes... how about other conditions? I guess = it may be safe to initialize things every time dtnd starts, but that = would wipe out any cached bundles and kind of defeat the = purpose...

Thanks

Hi Tom,

The = error 'in ipc communication' in this case occurs as there is no = dtnd

All the best,

The log file indicated that the globals table was missing when you started dtnd. That indicates that the database was either deleted or corrupted after the previous run. Also the .ds_clean file that is created when the database is cleanly shut down at the end of the previous run was missing. This indicates that something went wrong at the end of the previous run or you changed where the database was stored. You normally only need to use --init-db at cold start, or after moving the database to a new directory (and not moving the files), or after changing the storage mechanism, although it is sometimes necessary during development when things go badly wrong. It might also be necessary if, e.g., you manually deleted some bundle files. Usually using --tidy is enough to get things going again - this reinitializes the tables and gets rid of existing data. v2.8.0 has been somewhat superseded but I haven't seen this problem despite using DTN2 a great deal over the last 6 months, and leaving instances running for days at a time. > > > > Check it with dtnping and then use dtncpd. > > > > BTW Quite a lot of the directory creation stuff that you have added > > in > > to dtn.conf is unnecessary - --init-db automatically creates the db > > and > > bundles directories provided the base dbdir is present and > > writeable. > > Its also wise to be explicit about the storage type you are using - > > you > > are using the default berkeleydb I believe. > > > > If you haven't done so, (and maybe even so) have a read of the > > tutorial > > in the DTN2/doc/manual directory which describes getting started. > > > > > > > Thanks for your help Elwyn - I have gone through the tutorial in the > past; it's okay as a starter, but do you know of a more extensive > tutorial?

or after = moving
the database to a new directory (and not moving the files), or = after
changing the storage mechanism, although it is sometimes = necessary
during development when things go badly wrong.  It = might also be
necessary if, e.g., you manually deleted some bundle = files.

Usually using --tidy is enough to get things going again - = this
reinitializes the tables and gets rid of existing = data.

v2.8.0 has been somewhat superseded but I haven't seen this = problem
despite using DTN2 a great deal over the last 6 months, and = leaving
instances running for days at a time.



Check it with dtnping and then = use dtncpd.

BTW Quite a lot of the directory = creation stuff that you have = added
in
to dtn.conf is unnecessary - = --init-db automatically creates the = db
and
bundles directories provided the = base dbdir is present and
writeable.
Its also wise to be explicit = about the storage type you are using = -
you
are using the default berkeleydb = I believe.

If you haven't done so, (and = maybe even so) have a read of = the
tutorial
in the DTN2/doc/manual directory = which describes getting = started.





Thanks for your = help Elwyn - I have gone through the tutorial in = the
past; it's okay as a = starter, but do you know of a more extensive
tutorial?

A comment we have heard = before (and quite recently).  No, there isn't.
One of us will = have to settle down and do some = more.

Elwyn




Thanks,


Tom

Initializing the database each time I run dtnd seems like = a rather

Hi,

 

I successfully installed DTN2 and run the typical dtnping, = dtnsend, dtnrecv commands of the manual.

 

I would like to go a bit deeper to = the subject and I was just playing around with the API, trying to make a = simple app that sends/receives/pings over DTN (using just the localhost = as sender / receiver)

 

The following code is not working and I would really = appreciate any kind of help / support since I am not sure I am on the = right track here.

 

Many thanx.

 

int main(int argc, char** argv) = {

          =       char *const ps_argv[] =3D = {“dtnping”, 0};

          =       = execv(“/home/pantelis/dtn/apps/dtnping”, = ps_argv);

          =       return = (EXIT_SUCCESS);

}

 

I am using NetBeans7, on Ubuntu = 11.10
