Transport of Signaling over IP
... What’s wrong with TCP for transport of signaling? • HOL blocking: Two network nodes signal at the same time about many independent calls. TCP ties them together – one lost message concerning a single call causes sigaling of other calls to halt until retransmission recovers the lost message. • TCP i ...
