Some performance issues associated with high speed LANs, MANs and WANs

摘要

Issues discussed at the 13th International Teletraffic Congress (ITC-13) regarding high speed local area networks (LANs), wide area networks (WANs) and metropolitan area networks (MANs) are reviewed, and some important problem areas that remain are noted. Specific areas addressed include performance of two important emerging MAN standards, namely distributed queue dual bus (DQDB) and fiber distributed data interface (FDDI), retransmission protocols in high-speed networks, and related questions of fairness.
