Abstract: An improved user data protocol involves a multi-addressing capability that allows a user at a source node to address a single message to many users at respective destination nodes within a communication network. The multi-address messages that are provided to the network are inserted once at the source node, and messages routed between network nodes going to the same next node travel once across each interconnecting communication channel, thereby minimizing the communication bandwidth consumed.

Abstract: An improved user data protocol is well suited for both Internet radio and packeting switching networks and provides built in addressing and transport control capabilities. Basically, the user protocol consists of layers 4, 3, and 2 of the seven layer OSI/ISO model. The protocol enables communications between Data Comminations Equipment and Data Terminal Equipment and particularly is adapted to provide communications both voice and data between radios. The main feature of the IMPROVED Protocol is the ability to transmit multiple data frames in a single transmission including the transmission of a particular synch.
