RE: making psamp export congestion-aware

["Ayyasamy, Senthilkumar (UMKC-Student)" <saq66@umkc.edu>]

The use of UCP/TCP/SCTP doent make a big difference when a service provider
exports to a separate network for network management.But,sometimes the 
non-local network used for network management will become a hindrance as
the SP network grows leading to surging export cost .Also,sometimes a 
combination of TCP and increasing gap between exporter and collector(because 
of non-local management takes extra buffer and unusual fail over schemes.
So,I think use of separate network for management is itself makes things
complex leave alone use of TCP/SCTP.
