4. February 13, 2008Net@EDU StateNets Slide 4 ROADM Overview Built using the Nortel CPL (common photonic layer) boxes. The system has the capability to transport 9 groups of 8 wavelengths over the network. With the currently available equipment in BCNET and Canarie that has a potential bandwidth of 72 * 10 Gb/s is 720 Gb/s.  ready to transport 40G/bs wavelengths (OC768).  potential capacity of 28.8 Tb/s.

5. February 13, 2008Net@EDU StateNets Slide 5 Wavelength Assignment The CPL system uses different groups of wavelength. For each group a channel mux (multiplexer) is needed, In the network 2 groups of 8 wavelengths are being used.  Group 6 (CANARIE) contain the wavelengths 1550.116nm to 1552.926 nm  Group 7 (BCNET) contain the wavelengths 1554.134nm to 1556.959 nm

8. February 13, 2008Net@EDU StateNets Slide 8 10G Routing – possible design

9. February 13, 2008Net@EDU StateNets Slide 9 10G Routing Requirements Support 10Gb/s IPv4 and IPv6 routing, both unicast and multicast on each TX. Support 10Gb/s switching on each TX. Support multiple routing tables and/or routing instances Have the capability to implement transparent point to point Ethernet lightpaths over the network. These lightpaths should offer a set of minimal QoS levels such a minimal/maximal bandwidth. Make optimal use of the available network resources by having offering flexible protection and restoration schemes.
