—A group of network protocols that share a common format of network address. Address families are defined by RFC 1700.
—autonomous system. An IP term to describe a routing domain that has its own independent routing policy and is administered
by a single authority. Equivalent to the OSI term “routing domain.”
—Border Gateway Protocol. Interdomain routing protocol that exchanges reachability information with other BGP systems.
—Connectionless Network Service. An OSI network-layer protocol.
—Common Management Information Protocol. In OSI, a network management protocol created and standardized by ISO for the monitoring
and control of heterogeneous networks.
—data communications channel.
—data communications network.
—End System-to-Intermediate System. OSI protocol that defines how end systems (hosts) announce themselves to intermediate
—File Transfer, Access, and Management. In OSI, an application-layer protocol developed for network file exchange and management
between diverse types of computers.
—Interior Gateway Protocol. Internet protocol used to exchange routing information within an autonomous system.
—Interior Gateway Routing Protocol. A proprietary Cisco protocol developed to address the issues associated with routing in
large, heterogeneous networks.
—intermediate system. Routing node in an OSI network.
—Intermediate System-to-Intermediate System. OSI link-state hierarchical routing protocol based on DECnet Phase V routing,
where routers exchange routing information based on a single metric, to determine network topology.
—International Organization for Standardization. International organization that is responsible for a wide range of standards,
including those relevant to networking. ISO developed the Open System Interconnection (OSI) reference model, a popular networking
—network service access point address. The network address format used by OSI networks.
—Open System Interconnection. International standardization program created by ISO and ITU-T to develop standards for data
networking that facilitate multivendor equipment interoperability.
—The OSI term that is equivalent to autonomous system for BGP.
—Synchronous Digital Hierarchy. Standard that defines a set of rate and format standards that are sent using optical signals
—Synchronous Optical Network. High-speed synchronous network specification designed to run on optical fiber.
