DESIGN AND IMPLEMENTATION OF A TRANSPORT LAYER PROTOCOL ON HP-9000 SYSTEM

Abstract

The Transport layer of the CI reference model is the only layer within the architecture with the t overall responsibility for controlling the transfer of data between open systems. Thus the Transport layer has been the subject of intense activity since it, along with the Network layer, is the key to inter-connecting geographically remote open systems. The objective of the present work is to design and implement a Transport layer protocol. A protocol with features of class 0 protocol in addition to multiplexing and error detection of class 4 protocol, as per the CCITT recommendations, has been designed. To demonstrate the protocol, two application processes offering message handling services and a network layer have also been designed. The software has been written in the C programming language and is implemented on W-9000 system.
