This document specifies a new TCP option that specifies services by a string name. This option separates the use of port numbers for connection demultiplexing from their use as a service identifier. The option allows a larger number of concurrent connections for a particular service, as well as potentially enabling more explicitly coordination of services behind NATs and firewalls. This option should be supported in new TCP implementations.
