migration from channel traffic to qllc traffic

I have to migrate my sna traffic, now direct attach to channel Escon with cpa interface, to qllc with x25 interface to 3745 controller conected to a serial interface of the router.

I have to know what x25 bandwidth may I reserve. I can see the cpa traffic ( with "show interface channel " in the router. The question is what is the relation between 2 kind of traffic. What overhead add the x25 encapsulation?

Thanks.

Regards

Re: migration from channel traffic to qllc traffic

A direct channel connection can operate at a theoretical speed of 17 MBytes/sec. This is extremely fast and is unlikely to be matched by anything close in a serially attached X25 connection and the overheads of the X25, QLLC headers will add to the problem. It is more usual to migrate from an X25 network to a CIP for greater bandwidth!

I agree with you, but I am studying the qllc link only for a disaster recovery path.

Thanks
