Patent ID: 7353530

Claim:
A communication system comprising: a plurality of broadband telephony interfaces for providing a plurality of respective customers with service from at least one service provider; a plurality of nodes for relaying the service; a plurality of cards for controlling the service; a plurality of coaxial and/or fiber optic cables connecting said nodes to said interfaces and to said cards; a comprehensive model created by simultaneously evaluating the minimum margins for all said cards using the linear relationships among customer distribution data and a set of constraint conditions for said cards; a model solving module for mathematically solving the model using linear, integer, and binary programming techniques, to determine an infrastructural assignment arrangement of all said cards and all said nodes, wherein the number of said nodes being assigned to said cards are distributed to allocate traffic as evenly as possible, wherein said module optimization is represented by: max [x*z] where x[i, c] is an assignment variable which equals 1 when a specific said node “i” is assigned to said card “c” or 0 otherwise; y[c]≧0, indicating the leftover capacity for households or margin present in card c; w is a weight of 1 when the search reaches an optimal solution and remains 0 when it is searching for a feasible solution, Σx[i, c]=1: for all “i” when every node must be assigned to some card; Σx[i, c]≦SMAX: for all “c” so that a card can serve at most SMAX nodes; Σx[i, c]*H[i]+y[c]=HMAX: for all “c” such that a card can serve at most HMAX households; y[c]≧z: for all “c” such that all cards must have at least a margin or unused capacity of z households; and z≧YMAX such that the minimum margin must be at least YMAX.
