Architecture of Network Systems

Chapter 2. Network protocols and network systems

Abstract:

The different engineering approaches to the problem of telecommunications and networking, the diverse application areas, and the quest for proprietary solutions have resulted in a large number of differing network designs. Most networks are organized in layers, where each layer represents a level of abstraction focusing on the communication/networking services it provides. In layered network architecture, every protocol layer of a node communicates with the equivalent protocol layer of another node. The International Organization for Standardization has worked to develop a reference model for open communications. Network systems are computational systems that execute protocol stacks and ...
