摘要： Discard precedence priority of packets carrying an encoded video stream in a packet network is determined based on priority information included in the encoded video stream. A video streamer segments an encoded video stream and encapsulates the segment in an Internet Protocol (IP) packet. Priority information associated with the IP packet is determined based on at least one priority indicator associated with the segment that was included in the encoded video stream. Alternately, priority information associated with an Ethernet frame is determined based on at least one priority indicator associated with the segment that was included in the encoded video stream.

摘要： A method and apparatus are provided for low latency loss-free burst switching. Burst schedules are initiated by controllers of bufferless core nodes and distributed to respective edge nodes. In a composite-star network, the burst schedules are initiated by any of a plurality of bufferless core nodes and distributed to respective edge nodes. Burst formation takes place at source nodes and a burst size is determined according to an allocated bitrate of a burst stream to which the burst belongs. An allocated bitrate of a burst stream may be modified according to observed usage of scheduled bursts of a burst stream. A method of control-burst exchange between each of a plurality of edge nodes and each of a plurality of bufferless core nodes enables burst scheduling, time coordination, and loss-free burst switching. Both the payload bursts and control bursts are carried by optical channels connecting the edge nodes and the core nodes. A method and a circuit are provided for generating burst descriptors wherein each burst is associated with a burst stream and each burst stream is allocated a service bitrate. The generated burst descriptors are used in each master controller in each core node to create the burst schedules. In a conventional burst-scheduling process, the burst queues at a master controller of an optical switch receives burst descriptors from the source nodes and schedules the burst switching times. In a distinct departure, according to the present invention the burst descriptors are generated by a master controller of an optical switch in a core node, the switching times of the corresponding bursts are scheduled, and the schedules are distributed to the respective edge nodes. The burst-descriptor generation is based on burst-stream bitrate-allocation defined by the source nodes.

摘要： A network resource is allocated to a data path by determining if a sufficient amount of the network resource is available in a network path to accommodate the data path, and obtaining a cost associated with using the network resource available in the network path for the data path. It is decided whether to allocate the network resource in the network path to the data path based on the amount of the network resource and the cost associated with using the network resource. One representative example of the data path is a label switched path (LSP) on a multiprotocol label switching (MPLS) network.

摘要： In a router, externally received messages addressed to an active line card are bridged to a protection line card. Each line card in the router is programmed to respond to such externally received messages by directing them to the protection line card associated with the active line card as well as to the active line card. The protection line card is configured with inbound and outbound path tables that are the clones of the inbound and outbound path tables of its corresponding active line card. Bridging is accomplished by revising descriptors stored in a plurality of line cards to indicate an association between an active one of the line cards and its protection line card. Received messages are addressed using the revised descriptors to the active line card and also to its protection line card. Upon failure of an active line card, its physical interface can be disabled once its protection line card has clones of the inbound and outbound path tables and bridging has been set up.

摘要： A method and apparatus for scheduling the transfer of data bursts in a network comprising electronic edge nodes interconnected by bufferless core nodes are disclosed. Each edge node comprises a source node and a sink node, and each core node comprises several bufferless space switches operated in parallel. Each source node is connected to at least one core node by an upstream link that includes multiple upstream channels. Each core node is connected to at least one sink node by a downstream link that includes multiple downstream channels. Any of the space switches can have either an electronic fabric or a photonic fabric. Each space switch has a master controller, and one of the master controllers in a core node is designed to function as a core-node controller in addition to its function as a master controller. Each master controller has a burst scheduler operable to compute a schedule for the transfer of data bursts, received from source nodes, to destination sink nodes. In one mode of operation, each source node determines the bitrate requirements for paths to each sink node and sends bitrate-allocation requests to a core-node controller. A core-node controller receives requests for bitrate allocations from source nodes and assigns each request to one of the master controllers of the core node. Each master controller then computes burst-transfer permits and sends the permits to corresponding edge nodes. Each permit specifies a burst size, a destination sink node, the time at which the burst should be transmitted from its source node, and the upstream channel to be used. It is emphasized that in this mode of operation, the source node communicates information on burst streams not on individual bursts. In another mode of operation, each source node determines a descriptor of each unscheduled waiting data bursts and communicates the burst descriptors of all unscheduled bursts to a controller of a core node. The core-node controller then directs each burst descriptor to one of the master controllers of the core node which then computes a schedule for burst transfer and sends the schedule to corresponding edge node. The schedule indicates the upstream channel to be used for each burst and the time at which each burst, already waiting at the source node, should be transmitted to the core node. The scalability of the network is determined, in part, by the processing capacity of the burst scheduler and techniques for circumventing this limitation are described in this disclosure.
