HYBRID GRIDNET: Packet and circuit switching in a single network
Abstract
GRIDNET is a packet switching network, composed of multiply connected dual loops, being developed for the Defense Nuclear Agency in order to provide highly survivable data communications among a large number of sites. This report describes a concept for overlaying such a network with additional channels and switching facilities that may be used to establish point-to-point circuits on a demand basis. Switched connections are established following the exchange of appropriate frames between the stations that are involved. These exchanges use the regular GRIDNET packet switching facilities to provide essential supervisory and control functions including collision avoidance by means of circuit reservation in advance of connection.
