Found this information in Dec 8th Infoworld Magazine.infoworld.com December 8, 1997 (Vol. 19, Issue 49) Delays hinder IP Navigator By Stephen Lawson Delays in integration of Ascend's IP Navigator software with the company's remote-access products may push back the availability of high-priority services from service-provider networks. The software, developed by Cascade Communications before its merger with Ascend last spring, allows packet traffic to be switched across a WAN built with Cascade ATM and frame-relay switches. Engineers are now working on extending it to Ascend's Max line of remote-access devices and GRF routers, and adding features that will let service providers offer guaranteed latency and delay for high-priority traffic. With this software available from one edge of the WAN to the other, voice, video, and high-priority applications could be carried reliably across an IP network. But some observers said the work has fallen months behind schedule. "By now the IP Navigator support across the Max 4000 line and the GRF should all have happened," said John Morency, principal at The Registry, in Newton, Mass. "This is more complex than they thought." Morency doesn't expect the software to be extended to these products until the second quarter. According to sources, Ascend had planned to announce IP Navigator support in the GRF at NetWorld+Interop in October. (See "Switching into high," Oct. 6, page 1.) Sources said the merger has been a rough one and attrition from the Cascade division may have slowed product development. The stakes are high, with ISPs and enterprises already demanding differentiated services. "There's a huge opportunity for ISPs to move corporations off the more expensive private-network services onto the public-network core," said John Coons, an analyst at Dataquest, in San Jose, Calif. The only other company close to providing this capability in products spanning the WAN is Cisco, according to observers. The company's Tag Switching technology is not expected to ship for both its routers and large core switches until late summer 1998. Ascend officials last week said that IP Navigator development is proceeding as planned and that the extended capabilities will be available in 1998.
