LINCS Session, Presentation, Common Application/Service Protocols Common Across Applications/Service

摘要

The Livermore Network Communication System (LINCS) is a layered architecture designed to support distributed computing. This document contains protocol specifications and conventions for protocols in three LINCS layers, the Session Layer (Layer 5), Presentation Layer (Layer 6), and the lower sublayers of the Application Layer (Layer 7). We briefly review the functions of each of these layers. The active communicating entities in LINCS are processes, where a process is informally understood as an instance of a program in execution. Processes communicate through ports. Ports are identified by globally unique identifiers called addresses. A pair of ports defines a full duplex information channel called an association. LINCS protocols have been explicitly designed for minimum delay (there are no ''connection'' opening or closing message exchanges) and for maximum throughput. (ERA citation 07:062552)
