Abstract
This redbook gives a mid-level description of the Advanced
Peer-to-Peer Networking (APPN) architecture. It provides a tutorial
on the APPN architectural functions, how the different functional
components work together, and a summary of APPN implementations in IBM
products. This enables the reader to fully understand how APPN works,
how it differs from other networking solutions (for example, TCP/IP),
and which IBM products have implemented APPN functions. This
knowledge can be used to make decisions on future networking strategy,
to help in the design and planning of APPN networks, and to aid in the
understanding of functioning networks.
This revision includes updated chapters on high-performance routing
(HPR) and Adaptive Rate Based flow/congestion control (ARB) that
describe recent changes to APPN architecture to more efficiently route
data through high-speed networks. Also, the extended border node
(EBN), dependent LU requester/server (DLUR), and native ATM DLC for
HPR functions are described in detail.
