Abstract
As described herein, a network device includes an optical circuit switch to perform circuit switching. The network device also has a plurality of removable line cards, each of which includes a packet switch. A switching manager automatically reconfigures the optical circuit switch based on a configuration of the removable line cards to maintain a guaranteed packet switching bandwidth between active line cards.
Claims19
A network device, comprising:
- an optical circuit switch to perform circuit switching;
- a plurality of removable line cards, each having a packet switch;
- and
- a switching manager to adaptively reconfigure the optical circuit switch based on a configuration of the removable line cards to maintain a guaranteed packet switching bandwidth between active line cards.
1 more element
A method, comprising:
- establishing an optical circuit switching framework using at least one optical circuit switch on a network, the optical circuit switch to perform circuit switching of optical signals;
- routing traffic on the network via removable line cards that each includes a packet switch performing packet switching within bounds of the optical circuit switching framework;
- and
- automatically reconfiguring the at least one optical circuit switch based on a change in configuration of the removable line cards, the reconfiguring to maintain a guaranteed packet switching bandwidth between active line cards of the removable line cards through the at least one optical circuit switch.
