摘要： Apparatus and method for supporting operations and maintenance (“OAM”) functionality in an OBS network is described. One embodiment is an OBS network having OAM functionality, the OBS network comprising a plurality of OBS nodes interconnected via links. Each of the OBS nodes comprises an OAM module (“OAMM”) for processing information regarding OAM functions in the OBS network and a routing manager (“RM”) for processing routing information; and wherein at least one wavelength in each of the links comprises an OAM/1 wavelength for OAM/1 transmissions between nodes, the OAM/1 transmissions comprising OAM activity information; wherein at least one wavelength in each of the links comprises a reference wavelength for providing a wavelength reference to which light generating devices in the OBS network lock; and wherein at least one wavelength in each of the links comprises a routing wavelength for providing routing information between nodes.

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.
摘要翻译：描述了用于光突发交换（“OBS”）网络节点中的应用的部分优先服务质量（“QoS”）调度模型。在一个方面，本发明包括一种仅丢弃与已经调度的数据突发的一部分重叠的被考虑的数据突发的一部分的方法。在另一方面，本发明包括只抢占与所考虑的数据突发的一部分重叠的已经调度的数据脉冲串的那部分，并整个调整所考虑的数据脉冲串。在一个实施例中，基于突发的相对优先级，决定是否丢弃所考虑的数据突发的一部分或抢占已经调度的数据突发的一部分。类似地，是否执行部分或全部丢弃或抢占的决定是基于突发之间的重叠量。

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.
