TN3270E technology allows IP desktop traffic to access SNA host applications. The IBM 2212 provides a TN3270E logical gateway that integrates SNA and IP to enable IP desktop users to connect to SNA hosts via the Internet, intranets, and extranets. The IBM 2212 supports up to 1000 TN3270E sessions.

A Network Dispatcher feature, explained in the following section, provides traffic-load balancing across multiple IP and TN3270E servers. A TN3270E server can coexist in the same IBM 2212 as the Network Dispatcher function.
