IBM's Multiple Systems Networking Facility ( MSNF )

I have 2 mainframes. Each mainframe is part of a different logical SNA/VTAm network. Each mainframe has a front end processor ( FEP ). The mainframes communicate with each other through MSNF via a TIC on each front end processor. The communication consist of the transferring of batch jobs and RJE traffic.

I cannot go directly between channels on the mainframe because of IBM's limitations on traffic that passes through different networks.

I would like to get rid of the FEP's. I have CIP interfaces connected to both mainframes. Does any one know how to accomplish MSNF via CIP's?

Re: IBM's Multiple Systems Networking Facility ( MSNF )

Hi Phil,

The best approach is to take it to APPN, using Border node if the VTAMs have different NETIDs. Use Enterprise Extender (EE) if at all possible. Getting to IP transport removes all media and gateway issues. You could stop just short of EE, and use LLC protocols, and then bridge between the machines, using DLSw (or DLSw with FST for high bandwidth links) if they're geographically separated.

Rgds, Dan
