Re: [Discuss-gnuradio] I miss the TCP server and client blocks!

[Michael Piscopo]

No I haven't.  I did also do UDP blocks in the grnet module set, but from a reliability perspective they can be temperamental.  My experience with UDP at high speed was that it would drop packets resulting in too much data loss causing the streams to almost be useless for true decoding.  While TCP has overhead with it, if you switch to UDP you have to manage all of that anyway at a protocol level, and the throughput on TCP was never the flowgraph bottleneck anyway, so I just stick with the TCP blocks when I need them.

You haven't looked writing an RTP block by any chance? Thinking about writing one...

I felt the same way so I rewrote the TCP blocks in C++/boost with thread offloading a while back.  The package should be in pybombs but you can get it here https://github.com/ghostop14/gr-grnet.  Just basic TCP send/receive to replace the deprecated blocks.  Hopefully it helps.

Yeah, use the ZeroMQ blocks.

Trying to get the socket PDU blocks to send and receive a stream of data is proving to be a significant challenge. I miss the simplicity and reliability of the TCP server and client blocks - they always "just worked" for me. I don't understand why they were deprecated only to leave us with these buggy and difficult to use socket PDU blocks.

Sorry for the rant, I'm just running into one problem after another trying to get two flowgraphs to communicate using the socket PDU blocks (issue IDs 1770,1769,1763,1762).

These new ZeroMQ blocks look cool. Are they a good alternative?
