Has anyone compared the alternatives for TCP/IP implementations for the IBM MVS operating system (e.g. KNET, ACC, etc). A full function alternative, preferably with nice gateway capability to&from SNA networks would be ideal (dream on :-).

Last year we talked to ACC, Advintech (then called CISCO), Fibronics, and Network Solutions. We felt that ACC's product would best meet our needs. Due to long procurement delays, we are just about to get it, so I can't tell you how it worked out yet. I also asked some of the lists who was using what for MVS. The overwhelming majority response was ACC. Some of the product features that are important to us are SMTP, FTP, Telnet, TN3270, domain name resolver, a reasonable way to interface SMTP to our mail system, and a way to adapt FTP to our user and data set naming conventions. Some of the products lacked basic features like SMTP or TN3270. Others had interfacing problems in our environment. We weren't looking for an SNA Gateway, but I don't recall such a beast in any of the products.

A full function alternative, preferably with nice gateway capability to&from SNA networks would be ideal (dream on :-). That depends upon what you mean by a "gateway capability". A transport-level gateway doesn;t work because the upper layers are different. If you mean: the ability to use a 3278 transparently end-to-end across an SNA and a TCP-IP network, you've got it in the UCLA ACP and all the vendor products derived from it. If you mean: the ability to gateway BITNET mail to/from SMTP mail under MVS, there is a mail system available from UCLA that does that (with some restrictions). There is not a file transfer gateway because the two protocol families use such different file tranfer models. Bob Braden
