Abstract
This invention relates to the partitioning of a communications network. The idea of the invention is to divide the logical connections of a communication network into several partitions, each partition representing a certain type of transmission traffic, such as access or regional traffic. The partitioning is based on simple criteria: capacity of an endpoint of a logical connection, representing a node; distance between a pair of endpoints, and traffic category representing the stability of the traffic. By using the partitioning, it is possible to separate a certain type of traffic (a certain type of logical connections) from the whole traffic picture of the network.
Claims26
A network planning method for partitioning a communication network, said method comprising:
- describing logical connections in a network in a domain comprising at least two dimensions, the first dimension being for describing capacity needs of endpoints of said logical connections, and the second dimension being for describing re-routing needs of said logical connections;
- selecting a value range for each of the dimensions;
- searching for logical connections which are within the selected value ranges in the domain;
- forming a primary partition from the logical connections within the selected value ranges;
- using the primary partition to decide what equipment is placed in at least one endpoint;
- and
- equipping said at least one endpoint.
A network planning system for partitioning a communication network, said system comprising:
- describing means for describing logical connections in a network in a domain comprising at least two dimensions, the first dimension being for describing capacity needs of endpoints of said logical connections, and the second dimension being for describing re-routing needs of said logical connections;
- selecting means for selecting a value range for each of the dimensions;
- searching means for searching for logical connections which are within the selected value ranges in the domain;
- and
- forming means for forming a primary partition from the logical connections within the selected value ranges, said primary partition to determine what equipment to place in at least one endpoint.
A network planning system for partitioning a communication network, said system comprising:
- a describing unit configured to describe logical connections in a network in a domain comprising at least two dimensions, the first dimension being for describing a capacity needs of endpoints of said logical connections, and the second dimension being for describing re-routing needs of said logical connections;
- a selecting unit configured to select a value range for each of the dimensions;
- a searching unit configured to search for logical connections which are within the selected value ranges in the domain;
- and
- a forming unit configured to form a primary partition from the logical connections within the selected value ranges, said primary partition to determine what equipment to place in at least one endpoint.
An apparatus configured to search for logical connections having first and second dimensions which are within respective selected value ranges, said first dimension being for describing a capacity needs of endpoints of said logical connections, and said second dimension being for describing re-routing needs of said logical connections, and form a primary partition from the logical connections within the selected ranges, said primary partition to determine what equipment to place in at least one endpoint.
A computer program embodied on a computer-readable medium, the computer program being configured to control a processor to search for logical connections having first and second dimensions which are within respective selected value ranges, said first dimension being for describing a capacity needs of endpoints of said logical connections, and said second dimensions being for describing re-routing needs of said logical connections, and form a primary partition from the logical connections within the selected value ranges, said primary partition used to determine what equipment to place in at least one endpoint.
