Protocols for Loosely Synchronous Networks

Florissi, Danilo; Yemini, Yechiam

This paper overviews a novel transfer mode for B-ISDN: Loosely-synchronous Transfer Mode (LTM). LTM operates by signaling periphery nodes when destinations become available. No frame structure is imposed by LTM, thus avoiding adaptation layers. Additionally, LTM can deliver a spectrum of guaranteed quality of services. New Synchronous Protocol Stacks (SPSs) build on LTM by synchronizing their activities to LTM signals. Such signals can be delivered directly to applications that may synchronize its operations to transmissions, thus minimizing buffering due to synchronization mismatches. SPSs can use current transport protocols unchanged and, potentially, enhance them with the real-time capabilities made possible through LTM.
