Abstract

This paper describes the design and implementation of high-reliable light-weight real-time protocol(HLRP). The HLRP is one of the SSCS(Service Specific Convergence Sublayer) protocols. It supports peer-to-peer flow control, transmission error recovery, and the management of communication link for IPC(Inter Process Communication) in ATM Switching Systems. In general, SSCS protocols include the setup and release steps of communication link. However, SSCS protocol for IPC does not necessarily require those steps at the control plane of ATM protocol reference model. The information about the communicating objects such as processors and controllers are known at the time of system configuration stage. Therefore, we adopt permament virtual connection concept on the connections for IPC. There is no need for setup and release steps of communication link in IPC connection, and the link setup is simplified by the setup primitive for message delivery. We design a simplified protocol for implementing light-weight protocol by minimizing protocol states and by simplifying error recovery procedures. Due to HLRP, we could guarantee an assured data transfer service in ATM switching systems.
