Detailed Description

sctp url_protocol

url syntax: sctp://host:port[?option=val...] option: 'listen' : listen for an incoming connection 'max_streams=n' : set the maximum number of streams 'reuse=1' : enable reusing the socket [TBD]

by setting the maximum number of streams the protocol will use the first two bytes of the incoming/outgoing buffer to store the stream number of the packet being read/written.
