Example text

1 also shows a model for the shared link in the arbitrary network. We consider provisioning for traffic traveling from left to right along the link. Each wavelength on the link can be used to support one lightpath from one of the incoming fibers on the left side of the link to one of the outgoing fibers on the right side of the link. Broadly speaking, wavelength provisioning can be done in one of two ways. One option is to statically provision a wavelength by hard-wiring the nodes at the ends of the link to always route the wavelength from a given input fiber to a given output fiber.

3 Placement of Functionality The challenges are not just limited to protocols, but extend to architectural decisions regarding the placement of functionality. Architecturally, the DATE example represents one extreme where most of computation and coordination is moved into the distributed protocols that run in the routers. 1, this means much of the measurement, control, and optimization is pushed down into the network. One can consider another extreme, where the network management systems bear all the responsibility for adapting to changes in network conditions, as in [15].

This was the first scheme for routing arbitrary permutation in a sparse network in O(log N ) time. Since then, such randomized routing has been used widely, and is often referred to as (VLB), randomized load-balancing, or two-phase routing. VLB has many good characteristics. It is decentralized, where every node makes local decisions. This also makes the scheme scalable. VLB is agnostic to the traffic matrix because the randomness erases the traffic pattern, and different traffic matrices can result in the same load on the links.
