Vincent Rendenna, senior instructor at AT&T in Piscataway, N.J., says the company is standardizing on TCP/IP as a means to provide interoperability among AT&T’s mainframe, Unix and PC environments.
“TCP/IP provides interoperability between our different operating systems. In addition, our 3270-type terminals are on their way out. We’re heading toward TCP/IP Because it’s the best protocol to let Return to Tiffany bead bracelet users access other LANs as well as to the mainframe,” Rendenna says.
Open Systems Interconnection appears to be a remote alternative to TCP/IP. Forty-eight percent of users are moving to TCP/IP as the standard protocol to support multivendor networks, while just 6% have tapped the OSI protocol for that task.
Despite TCP/IP’s popularity, IBM still has a shot at convincing users that its APPN strategy is a viable alternative. APPN is Big Blue’s so-called modern day strategic network technology that allows SNA devices to communicate as peers without mainframe intervention.
About 53% of respondents believe APPN has the ability to support a Return to Tiffany heart lock charm and bracelet enterprise network down the road, once IBM’s High Performance Routing–an improved version of APPN–is available.
According to analysts, APPN is more like SNA than any of the routing-oriented connectionless protocols, enabling APPN to deliver the same kind of application services in a distributed computing environment as subarea SNA does in a host-based computing environment. That is, it provides deterministic connection, reliable response times and reliable job completion times, as well as supplies a proper balancing and prioritization of various applications.
But McConnell says IBM still has a lot of mind-share selling to do Return to Tiffany Bead Bracelet APPN can command widespread user support.
“APPN has the potential to give TCP/IP a run for its money, but it’s clear from the survey that IBM hasn’t done the best marketing job, since almost half the users still don’t think it can fly as a multiprotocol transport.”
Nolle, however, has a different take. “I’m surprised that almost half did express confidence in APPN, since APPN is still poorly understood by most users outside the data center,” Nhe lle says. “Given that APPN hasn’t really gotten populist play in the enterprise, it appears that IBM is doing a good job in getting its message across Elsa Peretti Eternal Circle Bracelet all.”
Neil Peffer, manager of information systems (IS) at Miesel/Sysco, a division of Sysco, a food service warehouse and distribution company based in Canton, Mich., says he is attracted to the prospect of APPN because of its ability to support multiple platforms in a client)server environment.
