Re: [dtn-users] MSFC DTN2 Patches - 2016-02-29

Hi David,

This looks like a very interesting release.

I did some quick tests using my Ubuntu 15.10 VMs running on VMWare Fusion
and thought I'd report back on progress so far.

I did a "make clean" of all previous oasys, dtn2 and (in my case) LTPlib
installations, then downloaded, patched and installed dtn2 and oasys
without any issues. I did deviate slightly from the build instructions as I
used hg clone the latest builds:

hg clone http://hg.code.sf.net/p/dtn/DTN2 dtn2

hg clone http://hg.code.sf.net/p/dtn/oasys oasys

The following tests completed successfully without any issues. (There were
no network simulations between the nodes): UDPCL (100 x 63k bundles), TCPDL
(100 x 1M bundles), LTPUDP (100 x 63K bundles).

I used the default settings for all LTPUDP link parameters and it seemed
very fast.

I will run the same tests through some network simulations on my Pi
test-bed at some point soon and report back how I get on.

Kind Regards,
Nik
