Network resource provisioning method for bandwidth guarantee per flow
First Claim
1. A method of provisioning network resources in a differentiated service Internet in which necessary bandwidth is requested in units of flows for bandwidth guarantee per flow, comprising:
- (a) setting an optimum path between a source node and a destination node based on a request for traffic for a specific period of time;
(b) performing static provisioning in which bandwidth is allocated to each service class of the optimum path;
(c) determining whether connection admission is to be performed by determining whether all of the statically provisioned bandwidth allocated to the optimum path is being used; and
(d) if it is determined in (c) that connection admission is not to be performed, performing dynamic provisioning in which additional bandwidth is allocated to the optimum path based on a request for traffic by a newly incoming flow.

Abstract
Provided is a network resource provisioning method for bandwidth guarantee per flow in a differentiated service Internet in which bandwidth needed for each flow is individually requested. The method comprises setting an optimum path between a source node and a destination node based on a request for traffic for a specific period of time; performing static provisioning in which bandwidth is allocated to the optimum path according to a service class thereof; determining whether all of the bandwidth allocated to the optimum path by performing static provisioning are used up, and accepting connection admission according to the determination result; and when connection admission is not accepted, performing dynamic provisioning in which additional bandwidth is allocated to the optimum path based on a request for traffic from a new incoming flow. Accordingly, it is possible to efficiently provide a quality-guaranteed service by accepting a request for bandwidth per flow.
