Abstract :
A modular design for parallel multiple access control of packet switched networks operating at gigabit-per-second rates is described. The speed limitation of the electronic components due to the serial processing of the media access protocol has been circumvented by transparent fragmentation and by parallel transmission and processing of the fragments. The packet is split among several synchronized parallel channels of a fiber-optic transmission system, and the media access protocol is performed only on one of the channels. A modular architecture with twelve 139 Mb/s parallel channels has been implemented for a 1.7 Gb/s metropolitan area network, and parallel media access control has been demonstrated on a 278 Mb/s channel derived from two 139 Mb/s channels multiplexed either in time, wavelength, or space
