Juniper walks on the edge

Juniper Networks announced a host of new features that it hopes will further expand its line of Internet core routers to the edge.

Touting new interface modules, application services, and IP services, Juniper has enhanced its M40 router to address the availability and varied connectivity needs of service providers.

"The edge is where service providers need the most reliability and security," said Kevin Dillon, director of product marketing at Juniper Networks. "It is also where service providers can build trust with their enterprise customers."

Juniper introduced several new hot-swappable physical interface cards (PICs), including a multichannel DS3 card that can be divided to allow service providers to offer DS-0 service (a single 64Kbps channel). A second card allows for channelised El service - the European standard for T1, which transmits at 2.048Mbps.

A third interface card allows for increased encryption functionality. The card can be used to provide encryption across a provider's backbone, as required by customers, as well as to encrypt the last mile between an enterprise and its service provider.

Juniper also announced upgrades to its OS that controls and directs network traffic, called JUNOS. The company added support for Layer 2 VPN service and the capability of maintaining packet forwarding even after a routing protocol goes down due to network stress - a common phenomenon caused by wide area outages. These outages occur frequently as traffic is routed across a number of various networks, each maintained differently and with different degrees of reliability.
