Peer-to-peer network management in an IBM SNA network

Management of IBM's Systems Network Architecture (SNA) peer-to-peer communication, called low-entry networking (LEN), is discussed. Prior to LEN, all host communications were hierarchical. LEN allows nodes like personal computers, AS400, and host applications to communicate with each other through the subarea network as peers. LEN nodes allow cooperative processing, initiate parallel and multiple sessions simultaneously, require less predefinition, and use a common LU6.2 interface. The management problems posed by decentralized processing, changes to management definitions, and dynamic session initiation are addressed. Research conducted in the The Travelers' network to determine impacts in the areas of installation, session management, problem determination, accounting and performance is reported.<
