Internetwork Protocol Approaches

TLDR

Interconnecting networks aims to deliver consistent services to users, requiring new end‑to‑end protocols or interworking of existing ones while addressing challenges such as addressing, routing, buffering, flow control, error control, and security. The study examines interconnection strategies for X.25 and ARPA research networks, discussing models of network interconnection and the role of internetwork protocols.

Abstract

The motivation for interconnecting networks is to provide one or more consistent services to the set of users of the interconnected networks. To provide these services either new end-to-end service protocols must be defined or the service protocols of the individual networks must be made to interwork. In either case the issues of addressing, routing, buffering, flow control, error control, and security must be considered. Two examples of interconnection strategy are examined: the interconnection of X.25 networks, and the interconnection of ARPA research networks. The models for interconnection of networks and the role of internetwork protocols are discussed.
