Abstract

The interference between retransmissions at the Logical Link Control (LLC) protocol and the Transmission Control Protocol (TCP) in a General Packet Radio Services (GPRS) network is studied in this paper by means of simulations. The factors that contribute to the TCP/LLC protocol interference are discussed. The results show that in the presence of wireless link errors, LLC protocol does not cause severe interference with TCP but will enhance the network performance when the LLC parameters are set properly.
