摘要： An algorithm is disclosed for performing alien-wavelength channel balancing on channels between optical network elements within an optic-fiber communications system. The algorithm determines initial values of various optimization parameters for each of the channels, such as the input launch power and operating conditions of optical amplifiers in the optical path, and calculates an initial total optimization offset for the channels based on the initial values of the optimization parameters for each of the channels. The algorithm then adjusts the optimization parameters to new values and calculates a new total optimization offset based on the new optimization parameter values. The algorithm repeats this process until the relative channel launch powers and optical amplifiers are optimized.

摘要： Provided is a method and system for rehome optimization of a telecommunications network. Optimal network configurations are determined according to automatically derived attributes associated with granulations of elements in the network called rehome circuit groups (RCGs). RCGs are automatically derived from the telecommunications network. RCGs are definable as a rehoming set of one or more circuits in the network. Optimal network configurations satisfy specified constraints and are calculated in accordance with cost objectives. Constraints include rehoming RCGs on criteria of having a relationship with other RCGs in the network and how to treat certain RCGs in the rehome process.

摘要： This is a system and method for optimally allocating multi-service traffic concentrators in telecommunications network. A problem model representing the telecommunications network topology is formulated and input to a linear programming algorithm for an optimal solution. In the model, data set indices are defined as those components and/or factors in the telecommunications network which affect various operations of the network, and include origination, concentration, and destination sites as well as different multiplexer levels at each of the sites. Decision variables representing measure of efficiency in the network and whose optimal values are to be computed by the linear program are defined to include concentrator node selection, concentrator to destination site connection status, and the number of optical carrier trunks for each concentrator. The values for each of the three variables provide the equipment quantity for optimally allocating multi-service traffic concentrators. The objective function to be minimized is defined as minimum of the sum of total transmission cost between selected origination sites and selected concentration sites, total transmission cost between selected concentration sites and selected destination sites, total unit cost of concentrators, total port cost on the low side of the concentrators, and total optical carrier level port cost on the high side of the concentrators and the destination switches.

摘要： A method of optimizing a network includes a plurality of nodes interconnected by high multiplex level links, in which at least some of the links carry a number of low multiplex level remaining demands that is less than the capacity of the links, by rerouting lower multiplex level remaining demands through the network to reduce the total number of higher multiplex level links in the network. The method eliminates from consideration any bridges and spurs in the network, thereby forming one or more connected components of the network. After the spurs and bridges have been eliminated from consideration, the method reroutes remaining low multiplex level demands through each of the remaining connected components of the network to reduce the total number of high multiplex level links in each remaining portion. Computationally, the rerouting step of the present invention includes the step of solving an integer multicommodity flow problem by minimizing the cost of links of each of the connected components, subject to a symmetry constraint, an initial solution constraint, a conservation constraint, and a modularity constraint.

摘要： An apparatus and method for producing a traffic aggregation map for a telecommunications network where the network has at least one aggregation node and a plurality of access nodes. A computing device receives information regarding the identity of each node in the network and determines cost information relating to pairs of the nodes. The cost information may be calculated by the computing device or received as input, or a combination of the two. Cost information is also assigned for each pair consisting of an aggregation node and a super node, which is not one of the aggregation or access nodes. To produce the map, the computing device calculates a minimum spanning tree interconnecting all of the nodes including the super node. Disregarding in most cases the connections terminating at the super node, the remaining connections are displayed on a display device, preferably superimposed on a geographic map.

摘要： A method of optimizing a telecommunications network in terms of transmission and equipment cost by multiplexing lower bandwidth level telecommunications demand-routes to form higher bandwidth level bundles, by determining, for each demand-route, whether the demand-route includes a patching subroute. For each patching subroute, the method finds a best bundle of demand-routes that includes the patching subroute. The best bundle is the one that has the highest cost gradient between the sum of the costs associated with the demand-routes included in the best bundle and the total cost associated with the best bundle. The method then multiplexes the demand-routes according to the best bundles.
