<p>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&reg; recommends that Enterprise Extender be used in place of AnyNet&reg;.</p>
<p>Communications trace is improved to capture HPR data running over IP networks,
allowing you to troubleshoot Enterprise Extender communications problems.</p><img src="deltaend.gif" alt="End of change" />
