CANARIE lightpath services:

CANARIE lightpath services (a.k.a. private-line in industry) are delivered on GbE and 10 GbE

client interfaces over SONET. 10Gps SONET wavelengths are usually partitioned into smaller

capacity channels, from 155 Mbps to GbE, and up to a full 10 GbE. With the new ROADM

networks, lightpaths can also be 10GbE wavelengths that can be dropped directly into

researchers' equipment thus bypassing CANARIE optical switches. This reduces the total cost

(CANARIE and End-User) of bringing up a 10GbE lightpath. Canadian researchers will have

increased capability to develop and utilize high bandwidth applications in leading edge national

and international collaborations. As an example, the first ROADM 10GbE wavelength, from

Toronto to StarLight in Chicago, was delivered to Ryerson University to enable researchers there

to participate in the CineGrid project. This project potentially enables the streaming of 6Gbps 4K

motion picture video for motion picture production.

CANARIE IP Network services:

The CANARIE IP network is carved out of the CANARIE optical infrastructure. This is a layer 3

routed network service, with full and equal support for IPv4 and IPv6 unicast and multicast

routing. Internally the IP network comprises five major routing nodes and one minor, and seven

network segments and one minor. Each segment currently operates at 1 Gbps. To keep the

network segments uncongested, capacity can be increased in increments of 1 Gbps through

channel bonding, up to a maximum of 8 Gbps.

The five major IP nodes are located in Calgary, Winnipeg, Toronto, Montréal and Halifax. A

sixth smaller node was added in 2005 in Edmonton to aggregate IP network traffic for the Yukon

Territory and Northwest Territory GigaPoPs. In addition to the seven internal network segments,

there are six external network segments which extend to international R&E layer 2 exchanges: the

Pacific Wave in Seattle, StarLight in Chicago, and Manhattan Landing (MANLAN) in New York

CANARIE IP services are accessed through GigaPoPs, operated by one of the thirteen ORANs

(i.e. one per province, one for the Yukon Territory, one for the Northwest Territory, and one for

Federal Government Research institutions in Ottawa).

Figure 36 depicts the CANARIE IP network physical connectivity.  Through international

peerings at the international exchanges and through transit of R&E routes through some peers, IP

connectivity truly is global in reach.
