I just checked in a set of UDP source and sinks into the GNU Radio. These are designed to create a minimal operating UDP stream between two hosts, mostly for proof-of-concept testing. While you can do all of this in Python and the file_descriptor_sX, these should be easier to manipulate as they do much of the socket creation and exception handling for you. Note: these blocks have no concept of flow control and lost and dropped packets can easily occur. These blocks are meant to give you access to UDP streams, but you have to use them wisely. As examples, I created a couple of examples that were placed in python/hier/networking as they are implemented with the new hierarchical blocks. One pair allows you to send a dial tone between hosts and the other pair shows how to use it with vector data. Someone asked about multicasting. I haven't done much with multicast myself, but wouldn't this be easily doable by using a multicast address for the IP address? Or is there something specific that I'm missing with this? Tom

Cool! Can I use a UDP Sink to encapsulate demodulated FM into UDP packets for transmission over a network?

Just wanted to let everyone know that there is a fairly major bug in the operation of this code where bytes are lost depending on the speed of the flowgraph. I'll work this out later this week when I get back in my lab and have some time. Tom
