The optical network owner gets control over how much visibility routers get, with the option of giving the router full visibility.

The hangup with GMPLS was that carriers didn’t want to reveal their optical networks to other carriers’ routers.

Rathore also contests the notion that entire systems would be removed from the network this way. So, GMPLS fragmented into two models — “peer,” where routers get full visibility into the optical network, and “overlay,” where routers can place bandwidth requests but don’t get to see the topology of the optical network.

Cisco is announcing the developments in conjunction with its annual analyst conference, which begins tomorrow in Santa Clara, Calif. The idea was kicked around circa as a means of “collapsing” the network, removing a layer of Sonet equipment to save costs.

In many cases, IP-over-WDM just amounts to moving a transponder from an optical box into the router, he says. The idea complements Cisco’s strategy to use the same pluggable optics on its routers and on optical equipment like the ONS The cable operator hasn’t formally announced it’s using the router, but an official is quoted in Cisco’s release saying Cisco’s new DWDM interfaces represent “key reasons for our selection of the CRS
