System and method for designing a customized switched metro Ethernet data network
First Claim
1. A computerized method for automatically designing a switched metro Ethernet data network, the method comprising:
- receiving, at a computer system including a computer processor and a computer readable memory accessible to the computer processor, data network information;
receiving, at the computer system, customer demand information;
receiving, at the computer system, equipment information;
receiving, at the computer system, at least one design constraint; and
automatically establishing and storing within the computer readable memory of the computer system a potential topology design for the switched metro Ethernet data network at least partially based on the data network information, the customer demand information, the equipment information, the at least one design constraint, or a combination thereof, wherein a new aggregation node is added at a central office that is located between a plurality of customer nodes and a parent node of the central office in the potential topology design when costs associated with equipment to be added at the central office are less than costs associated with fiber hubbing the plurality of customer nodes to the parent node of the central office.

Abstract
A method for automatically designing a switched metro Ethernet data is provided. During execution of the method, data network information, customer demand information, equipment information, and at least one design constraint is received. Based thereon, a potential topology design for the switched metro Ethernet data network is automatically established. The potential topology for the switched metro Ethernet data network can be a tree topology that is rooted at a predetermined hub node and that has a plurality of leaves. Each leaf is located at a customer location. In a particular embodiment, an aggregation node is placed at the hub node. Further, an aggregation node is placed at a predetermined redundant hub node. Additionally, an aggregation node is placed at another location in the tree topology.
