摘要： Techniques for designing networks. The techniques utilize network management-based routing (NMS routing) in conjunction with the planning step (design-based routing) of the design process so that an optimal network may be designed. An automated technique for designing a network may comprise the following steps. First, one or more traffic demands are obtained. Then, a network is computed by determining one or more routes for the one or more traffic demands using a design-based routing methodology based on feedback from a network management-based routing methodology.

摘要： Network design techniques and techniques for routing virtually-concatenated data traffic in a network in a manner which distributes delay to intermediate nodes of the network are disclosed. For example, in one aspect of the invention, a technique for routing virtually-concatenated data traffic in a network comprising a plurality of nodes comprises, for a given traffic demand to be routed from a source node to a destination node in the network, the following steps/operations. Two or more paths are determined to route the given traffic demand. Each of the two or more paths correspond to a member of a virtually-concatenated group. At least one path of the two or more paths comprises the source node, the destination node and at least one other node coupled between the source node and the destination node. Further, at least a subset of the source node, the destination node and the one other node buffer at least a portion of the given traffic demand such that a delay is distributed over the at least one path. The given traffic demand is routed over the two or more determined paths. The at least one path is preferably the shorter of the two or more determined paths.

摘要： Techniques for network routing and design are provided. A technique for determining a route for a demand in a network, wherein the network comprises primary paths and secondary paths, and at least two secondary paths may share a given link, comprises the following steps/operations. First, a graph representing the network is transformed. Edges of the graph represent channels associated with paths and nodes of the graph represent nodes of the network. The transformation is performed such that costs associated with the edges reflect costs of using channels in secondary paths. Then, the shortest path between nodes corresponding to the demand is found in the transformed graph. The shortest path represents the least-cost path in the network over which the demand may be routed. When the above route determination steps/operations result in a path with at least one loop, an alternative routing process may be executed so as to determine a loopless path for the demand. Further, integer linear program formulation design techniques are provided.

摘要： Techniques are disclosed for designing optical transmission systems that efficiently compute cost-optimal configurations under one or more constraints. For example, in one aspect of the present invention, a technique for designing an optical transmission system comprises the following steps/operations. A set of one or more demands and a set of optical transmission system elements are obtained. Elements may be consecutively coupled via a span. At least one constraint on the design of the optical transmission system is obtained. The at least one constraint comprises: (i) a signal loss in a span should not exceed a given maximum signal loss; (ii) a signal loss in a span should not exceed a given maximum signal loss and a span should be longer than a given minimum span length; (iii) a signal loss in a span should not exceed a given first maximum signal loss and a span should be longer than a given minimum span length, however, at most one in m contiguous spans can have a loss up to a given second maximum signal loss, wherein the second maximum signal loss is greater than the first maximum signal loss; or (iv) a signal loss in a span should not exceed a given maximum signal loss and a span should be longer than a given minimum span length, and an average span loss of any m consecutive spans should not exceed a given average loss, wherein the average loss is less than the given maximum signal loss. A least-cost configuration is then computed for the optical transmission system based on at least a portion of the set of one or more demands and the set of one or more optical transmission system elements such that the at least one constraint is satisfied.
