Abstract: Traffic engineering is a key technology to improve network performance, and constraint-based routing(CBR) associating with MPLS is a new way to realize it. This paper proposes a new dynamic CBR algorithm——TERA, which satisfies bandwidth constraint and aims to achieve high throughput while holding network load balanced. After giving the mathematic model of TERA, it analyzes and describes the algorithm. Simulation result and conclusion are given.
