Hello Freek: A very nice picture indeed. Indeed lightpath capable domains interconnect among themselves, with dedicated lambdas and/or fibers. What I am missing from this picture is the notion of a GOLE (GLIF Open Lightpath Exchange), an important and growing element in today's global lightpath infrastructure. A GOLE is a typical point on the earth, and hence in the infrastructure, at which lightpath capable domains flock together, and stitch end-to-end lightpath's sections head-to-tail. How could this picture be updated showing a GOLE? Best regards, __ Erik-Jan. On 06/22/2010 06:00 PM, Freek Dijkstra wrote:
Attached is a picture (and source) that I've just shown at the NML group. It simply shows a few networks, the representation and delegation (virtualisation) of the network.
Feel free to use it to show a few of the issues that are associated with control, topology description, topology aggregation, and delegation.
Regards, Freek
