Hello All,

I am having some issues transferring a file using dtnsend/recv in a simple two node test bed using UDP convergence layer. The nodes are configured for static routing and dtnping functions as expected.

The issue I run into is when I attempt to send a file greater than ~130 KB and the result is the dtnrecv command doesn’t close (the file is not successfully transferred) and I can see in my bundle storage area a total size of bundles just slightly less than my expected file size.

The file size is specific because file sizes less than ~130 KB transfer just fine using the UDP convergence layer.

I am wondering if there is an issue with UDP convergence layer as changing nothing in my configuration besides the convergence to TCP layer, fixes the issue.

Any help would be appreciated.

IBR-DTN version: 1.0.1 (build 294b543)

Thanks,

John
