Abstract

A system, method and article of manufacture for communication in a network application. A connection or communication path to a replaceable transport is initiated in a network application. After the initiation, the network application creates an object to accept the connection or communication path. Once the connection or communication path is established, the network application provides QoS information for the replaceable transport to the replaceable transport, and to at least one object corresponding to the connection or communication path.
