A protocol within the XNS family used to exchange datagrams. One of five categories of network management defined by ISO for management of OSI networks. Performance management subsystems are responsible for analyzing and controlling network performance including network throughput and error rates. See also accounting management, configuration management, fault management, and security management. In SNA, a node that uses local addresses and is therefore not affected by changes to network addresses.
Peripheral nodes require boundary function assistance from an adjacent subarea node.
The location of a position on an alternating wave form. Contrasts with a network or protocol address, which is a network-layer address. See also hardware address . See physical layer. Lowest Level of the OSI Model.
