Connection Object

When the stack initializes a connection object, the stack sets the first element of a connection object to point to a structure. The structure tracks transactions that cache the connection object. The stack also uses the structure to break a TCP stream at the message boundaries.

Because the library does not interact with listening endpoints, it does not impose any restriction on creating or maintaining listening endpoints.

The connection manager maintains a unique connection object for each remote address, local address, and transport tuple. This behavior is particularly important for UDP, where the underlying endpoint does not uniquely identify a local/remote endpoint pair.
