SNA users looking to migrate to frame relay networks should examine the way in which access device vendors handle SNA traffic, rather than just looking at device performance.
That was the major conclusion drawn from a battery of tests recently completed by The Tolly Group, an independent testing firm based here. The company looked at the performance of seven leading Systems Network Architecture frame relay access devices from Advanced Computer Communications (ACC), IBM, Motorola, Inc., Netlink, Inc., Presticom, Inc. and Sync Research.
"For what amounts to the first generation of SNA-over-frame relay products, all of the vendors' products were remarkably stable," said Kevin Tolls Tolly Group president.
Tolly Group's test bed comprised two 16M bit/sec IBM Token-Ring nets connected over a 56K bit/sec frame relay link. A Cascade Communications Corp. STDX 3000 provided the frame relay access, while an...
