Abstract

Primary and alternate circuits on protocol flow objects representing application protocol layers in a communications channel are linked to connect multiplexed requests and replies. Various protocol flow objects are arranged in a hierarchical flow tree data structure that corresponds to multiple protocol layers in the channel. One branch of the flow tree data structure is selected to represent a reply, and source-destination address pairs for lower layer protocol flow objects for the reply are used to identify the branch of the flow tree data structure that represents the corresponding request. In one aspect, the address pairs for network and transport layer protocol flow objects for the reply are used to identify the request branch. In a further aspect, a link layer protocol object corresponding to the link layer protocol object for the reply may be used to reduce the number of network and transport protocol flow objects examined to identify the request branch.
