摘要： Methods and apparatuses for allocating backbone virtual local area network identifiers (BVIDs) to connection requests in a provider backbone bridging-traffic engineering (PBB-TE) network are described. During operation, a system (e.g., a network management system) can receive a set of connection requests for a set of connections that are desired to be set up in the PBB-TE network. Next, the system can allocate a BVID to each connection request in the set of connection requests so that, once the set of connection requests are set up in the PBB-TE network, conflicting connections in the PBB-TE network have different BVIDs.

摘要： A method for allocating the use of an optical light-trail includes calculating a bid at a first node in the light-trail with consideration for the criticality of the node's need to transmit particular traffic on the light-trail. The method also includes transmitting the calculated bid to one or more of the other nodes included in the light-trail. In addition, the method includes receiving an acknowledgment from one or more of the other nodes included in the light-trail, each acknowledgement indicating whether the transmitted bid is higher or lower than a bid calculated by the node from which the acknowledgment originates. The method also includes determining, based at least on the content of acknowledgements received, whether the transmitted bid is the highest bid.

摘要： A method for assigning a light-trail in an optical network includes identifying unassigned traffic flows in the network that require assignment to a light-trail, where each traffic flow is communicated from an associated source node to an associated destination node. The method also includes identifying which unassigned traffic flow includes the largest amount of traffic, establishing a new light-trail beginning at the source node of the identified traffic flow and ending at the destination node of the identified traffic flow, and assigning the identified traffic flow to the established light-trail. Furthermore, the method includes determining whether there are any unassigned traffic flows having associated source and destination nodes included in the established light-trail. If such unassigned traffic flows are determined to exist within the light-trail, the method includes assigning the unassigned traffic flows to the light-trail in order of the amount of traffic each traffic flow includes until a capacity of the light-trail is reached. The steps of the method are repeated until no traffic flows in the optical network require assignment to a light-trail.

摘要： A system and method for modularly scalable architecture for optical networks are provided. In one embodiment, a node for an optical network comprises a plurality of in-line switches connected to an optical ring and operable in a first state to both pass an optical signal received from the optical ring to an associated coupler and pass an optical signal received from the associated coupler to the optical ring. The optical signal carries traffic in a plurality of channels. A drop coupler is coupled to a first in-line switch and is operable to receive an optical signal from the in-line switch where the switch is in the first state, pass a first copy of the optical signal back to the in-line switch for passing to the optical ring, and drop a second copy of the optical signal to a distributing element. The distributing element is operable to receive the second copy and pass traffic in one or more channels of the second copy. A filter is operable to reject one or more channels of the first copy to generate a passthrough signal. A combining element is operable to receive traffic in one or more channels to be added to the optical ring and combine the received traffic to generate an add signal. An add coupler is coupled to a second in-line switch and is operable to receive the passthrough signal from the second in-line switch when the switch is in the first state, add the add signal to the passthrough signal to generate a combined signal, and pass the combined signal to the second in-line switch for passing to the optical ring.

摘要： An optical communication system includes an optical ring, a hub node, and a plurality of local nodes. The hub node and the plurality of local nodes are coupled to the optical ring. The hub node is capable of receiving traffic over the optical ring from the plurality of local nodes on a transmitting wavelength and of transmitting traffic over the optical ring to the local nodes on a receiving wavelength. The plurality of local nodes are capable of adding traffic to and drop traffic from the optical ring and at least one local node is capable of adding traffic to the optical ring by determining whether any other local node is transmitting at the transmitting wavelength. The local node adding traffic is also capable of transmitting a request message to the hub node requesting use of the transmitting wavelength, in response to determining that no other local node is transmitting at the transmitting wavelength. Additionally, the local node adding traffic is further capable of receiving a grant message from the hub node and, in response to receiving the grant message from the hub node, transmitting traffic at the transmitting wavelength.

摘要： A method and system for a data centric architecture in an optical network are provided. In one embodiment, a method and system for a data centric architecture in an optical network includes an optical ring. A number of local nodes are coupled to the optical ring and are configured to receive traffic at a receiving wavelength by optically broadcasting with electrical tag discrimination.

A data center node is coupled to the optical ring and operable to receive traffic from the local nodes, sort at least some of the traffic based on the destination of the traffic, and transmit the traffic at the receiving wavelength to the destination.

摘要： The present invention relates to allocating the use of optical light-trails. Optical light-trails enable a plurality of nodes included in a light-trail to share the use of an optical wavelength to transmit traffic between the nodes included in the light-trail. A method for allocating the use of an optical light-trail includes calculating a bid at each of one or more nodes included in the light-trail. Each of the nodes calculates a bid with consideration for the criticality of the node's need to transmit particular traffic on the light-trail. The method also includes transmitting the calculated bids from one or more of the nodes to an arbiter node. The arbiter node determines the maximum received bid, determines whether to allocate the use of the light-trail to the node associated with the maximum bid, and then communicates one or more control messages to the nodes that transmitted the bids indicating to which node use of the light-trail is allocated.
