ABSTRACT:
The real time Ethernet protocol (RTEP) of the present invention offers improved speed and performance for an Ethernet network, while simultaneously enhancing the Ethernet's communication functionality. The RTEP provides a data frame, within the standard Ethernet protocol frame, containing information to support network functionality ordinarily associated with higher level protocol layers. The RTEP can guarantee delivery of messages as well as correct message sequence. The RTEP also supports IP subnetting, message piggybacking, Ethernet network sharing, and dynamic replacement of Ethernet stations. The present invention has particular application in conducting communications between one or more hosts and a telecommunications switching system.
