Western ROADM Project Fibre

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.

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 nmGroup 7 (BCNET) contain the wavelengths

1554.134nm to 1556.959 nm

10G Routing – possible design

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.
