Abstract

Any successful B-ISDN must provide economical, reliable, and high-quality transport with a variety of bit rates. This is possible by combining two techniques. The first is optical transmission, which enables high-speed and long-haul transmission. Recent technical advances have permitted the commercial introduction of 2.5-Gbit/s systems, and systems of more than 10 Gbit/s are within our grasp. The other technique involves the use of transport nodes, which significantly enhances not only node throughput but also network flexibility and reliability with path-layer management.
