Juniper Router Speeds IP Switchover


Juniper Networks Inc. has unveiled a new multiservice router it said will help operators make the transition between older legacy and newer Internet Protocol-based data-delivery systems.

Available in October, with a list price starting at $120,000, the M120 multiservice edge router offers 10 Gigabits per second of throughput as well as a range of connection options, including Gigabit Ethernet and older non-IP transmission schemes such as asynchronous transfer mode (ATM) and digital video broadcasting-asynchronous serial interface (DVB-ASI). That is particularly useful for providers such as cable operators, which may have IP data and voice systems but also non-IP video delivery systems in the outer part of their service networks.

“For cable, they are very much ahead of the game in a sense that it moved to Ethernet — a lot of the transport is IP packet-based today, specifically on the data and voice side,” said John Treece, director of business development, cable products business. “But there are still some legacy broadcast video networks out there that they are still trying to migrate over.”

Over time, operators also can mix and match the connections as they transition to all IP and all-Ethernet transport schemes. Another selling point for the M120 is its increased availability, a measure of uptime and efficiency in routing traffic without dropping calls or data streams.

As with its other servers, the M120 also runs on Juniper’s Junos operating system. But it adds Juniper’s next-generation I-chip silicon, which can simultaneously handle such tasks as classifying packets and creating connections from the switch elements in the router. In doing so, it can lessen the number of hops data streams need to take in their journey, and it can handle increasingly complex applications.

“Whereas you may have only had to worry about data and a little bit of voice before, we’re going to start introducing video applications and scaling those voice and data applications,” Treece said. The I-chip “reduces latency within the network, and provides a robust processing engine that has the ability to scale with those services as they emerge and continue to grow on the network.”
