Internet connectivity exploitation and Enterprise Extender

Enterprise Extender enables remote branches or workstations to be connected to the SNA backbone using the Internet, with no application changes required, while maintaining SNA connectivity from end to end. Dependent LU sessions can be carried on an Enterprise Extender connection as easily as any others by using the dependent LU requester function.

Some of the benefits of Enterprise Extender include:

The key advantage of being able to consolidate onto a single transport network, which eliminates parallel networks, reduces equipment, lowers data circuit cost, and simplifies network management.
There are no changes required to SNA applications.
SNA can exploit the OSA Gigabit Ethernet interface cards.
End-to-end failure protection and data prioritization using the IP router network and z/OS Communications Server facilities.
