Chapter 26: Principles in Network Protocol
Overview
For a network to function efficiently, uniformity and consistency are required. This is one of the underlying reasons why standards setting organizations exist. Standards for network communications, hardware, and protocols have been in place for several years. The setting of these standards dates to 1978, when the International Standards Organization (ISO) began its description of network architectures that eventually became the guidelines for modern networking and Internetworking. The Paris-based ISO functions as the umbrella for several worldwide standards setting organizations composed of government, business, educational, and research groups (see Table 26-1). It continues to work toward the establishment of standardization for all services and vendor products.
