Juniper's T-series used in IP research

Juniper Networks' T-series high-speed routers are finding favour with researchers developing a faster Internet.

The first in the range - the T640 Internet Routing Node - supports 32 OC-192c/STM-64 ports, and offers eight 40G-bps slots. The device has a bandwidth density more than four times that of its closest competitors, Juniper claimed.

The T640's scalability and compatibility with the company's existing routers would allow network operators to expand their networks economically and make best use of existing resources.

France Télécom has already used the T640 in its very high-speed network testbed, a closed network linking research sites around France, France Télécom spokesman Manuel Lesaicherre said.

The T640 is also in use at the National Science Foundation's TeraGrid high-performance distributed computing project, and has been selected for use in the Internet2 Abilene research network, Juniper said.

By linking together several T640s, customers would be able to scale up their network to meet future bandwidth requirements, Juniper said. The T640 can carry data at up to 640G bps on the customer-facing side, and up to 1280G bps through the rear of the chassis with a backplane extension (an option at extra cost), it said.

This non-blocking, any-to-any extension allows multiple devices to operate as a single router using what Juniper calls its Matrix Technology. In this way, eight or more T640s could link together to provide 10T bps or more of throughput, the company said.

The T-series uses the same Junos operating software as Juniper's existing M series of routers, meaning that service providers would have access to the same features and services, the statement said. Junos supports MPLS (Multiprotocol Label Switching) and hardware-based IPv6 forwarding.
