Detailed Description

Demultiplexes packets to various transport layer endpoints.

This class serves as a lookup table to match partial or full information about a four-tuple to an ns3::Ipv4EndPoint. It internally contains a list of endpoints, and has APIs to add and find endpoints in this demux. This code is shared in common to TCP and UDP protocols in ns3. This demux sits between ns3's layer four and the socket layer
