Connection management in a LAN to broadband ISDN gateway: a simulation study

An examination is made of a gateway, BERGATE, designed and developed as part of the broadband ISDN pilot BERKOM project of the German PTT. End systems support the ISO 8073 transport protocol on top of the ISO 8473 internetwork protocol. Each BERGATE may access a single circuit switched H4 channel. Data exchange between a pair of gateways is possible only after establishing an H4 connection between these gateways. Since ISO 8473 is a connectionless protocol, it gives no indication when to open and close the H4 connection. The performance of a simple connection management policy is investigated, and proper values of parameters for this policy are selected.<
