摘要： Apparatus and method for scheduling transmission of data bursts in an OBS network are described. One embodiment is a router in an OBS network, the router comprising a grouper module for collecting a group of BHPs arriving during a BHP collecting period and classifying each BHP of the group of BHPs into corresponding baskets depending on the data channel scheduling window of its corresponding data burst; a classifier and channel assignment module for assigning data bursts to appropriate data channels; and a channel scheduler for constructing an interval graph representing data bursts corresponding to BHPs classified in a single one of the baskets having overlapping segments on each data channel as adjacent vertices and scheduling data bursts on each data channel based on a process that finds a maximum number of non-adjacent vertices on the interval graph.

摘要： Fully redundant clock systems are provided on network nodes coupled by redundant multisegment psuedowires (MSPWs) within an internet-protocol (IP)-based mobile backhaul network. The primary clock system includes a primary master clock on a first node and a primary slave clock on a second node coupled via a primary MSPW, while the secondary clock system includes a secondary master clock on the first node and a secondary slave clock on the second node coupled via a secondary MSPW. The primary and secondary slave clocks synchronize with their respective primary and secondary master clocks via their respective MSPWs. A clock controller maintains the secondary clock system in a hot-stand-by mode, and upon determining that a switch-over is needed, automatically switches from the primary clock system to the secondary clock system.

摘要： A partially preemptive quality of service (“QoS”) scheduling model for application in an optical burst switched (“OBS”) network node is described. In one aspect, the invention comprises a method for dropping only an portion of a data burst under consideration that overlaps with a portion of an already-scheduled data burst. In another aspect, the invention comprises preempting only that portion of an already-scheduled data burst that overlaps with a portion of a data burst under consideration and scheduling the data burst under consideration in its entirety. In one embodiment, the decision whether to drop a portion of the data burst under consideration or preempt a portion of the already-scheduled data burst is based on the relative priorities of the bursts. Similarly, the decision whether to perform a partial or full drop or preempt is based on the amount of overlap between the bursts.

摘要： A scheduling system and methodology for use in a network switch element having multiserver, multiple-arbiter architecture. Ingress ports and egress ports coupled to the cross-connect fabric of the network element are provided with multiple ingress and egress arbiters, respectively, for effectuating an iterative arbitration strategy such as RGA or RG. Arbiter architectures include singe-arbiter-per-port; single-arbiter-per-server; multiple-arbiters-per-port; and multiple-arbiters-per-server arrangements, wherein the arbiters can be implemented using RRA, BTA, Flexible Ring, or any other arbiter technology. Depending on the iteration strategy, ingress arbiter architecture and egress arbiter architecture, a variety of iterative, multiserver-capable scheduling algorithms can be obtained, which scheduling algorithms can also be implemented in QoS-aware network nodes.
