Enterprise Extender is a networking architecture that allows Systems Network Architecture (SNA) applications to run over Internet Protocol (IP) networks using High Performance Routing (HPR). This is the preferred way to run SNA applications over IP networks with communications input/output adapters (IOAs), such as Gigabit Ethernet, since these IOAs do not require an input/output processor (IOP). Communications adapters that do not use an IOP do not support SNA, therefore, Enterprise Extender is required to run SNA over these adapters. IBM® recommends that Enterprise Extender be used in place of AnyNet®.
Communications trace is improved to capture HPR data running over IP networks, which allows you to troubleshoot Enterprise Extender communications problems.
