Link Scheduling System and Method

摘要

A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

1. A method for managing one or more links in a communication network, the method comprising:
receiving an initial schedule or information indicative of the initial schedule, the initial schedule determined based on at least a global parameter, wherein the initial schedule defines initial management of the one or more links; receiving a set of constraints related to the one or more links; modifying the initial schedule based on a local parameter and the set of constraints thereby generating a modified schedule, the modified schedule defining modified management of the one or more links; and transmitting instructions to activate the one or more links according to the modified schedule, wherein each link permits data transmission from a first node to a second node.
