[AG-DEV] Coming UMTP work

[Thomas D. Uram]

The support for UMTP bridging that has been developed by Namgon Kim is 
making its way into the Access Grid code repository.

The C portion of it is available via Subversion like so:

    svn co 
https://www.ci.uchicago.edu/svn/accessgrid/trunk/services/network/UMTP UMTP

It can be built in the usual manner:

    ./configure
    make

For now, this includes a modified version of the UCL common library, 
with the umtp executable in UMTP/examples/umtp.  To test umtp, do this:

On the UMTP server, which should be multicast capable:  umtp -s <server 
hostname> <port>

(the hostname is specified for selection of the network interface)

On the UMTP client:   umtp -m <server hostname> <port> <mcast address> 
<mcast port>

at this point, the server should begin exchanging packets for the 
specified multicast group with the client. 


Please do test this, as it is slated for inclusion in an upcoming AG 
release and we would ideally identify/fix bugs early. 

Note:  At present, the code will fail to build on Windows; that will be 
resolved very soon.
