Abstract

The problem of contention by applications for access to transport layer end ports is addressed by two mechanisms. The first mechanism is that of providing a dedicated generic port listener for each port that acts to accept or decline incoming connections on a port. In such a case only one listener monitors the port, and contention between applications is reduced. The second mechanism is the provision of a thin protocol aware layer between the transport layer ports and the client applications. The protocol aware layer comprises one or more protocol registers which are each able to parse an incoming data connection to determine whether it is in accordance with an application layer protocol. A protocol register has knowledge of applications which make use of the protocol and is able to route the data connection to one of the applications registered therewith.
