Call transport alternatives for interconnected wireless communication networks based on IEEE 802.6 MAN
Winnie Wong, Victor C. M. Leung, Robert W. Donaldson · 2002
Anticipated growth in demand for personal communications services suggests that current facilities will not be adequate for handling the associated growth in message and signalling traffic. A new distributed switch architecture, consisting of an IEEE 802.6 Metropolitan Area Network (MAN) has been proposed, to interconnect wireless radio basesites with each other within a local region. Each MAN is then bridged to adjacent MANs, as well as to a backbone MAN for improved reliability and speed. Queue arbitrated (QA) access is provided to each MAN. A six-MAN network is simulated to determine the delay-throughput performance for both voice and data traffic, subject to voice traffic having priority over data. Of the 310 Mb/s capacity available, in the absence of signalling traffic, 290 Mb/s can be used, and provides source-to-destination transmission delays of less than 5 ms for up to 200 Mb/s of voice traffic.
