PCEによるマルチレイヤトラヒックエンジニアリング機能の実装と評価

To achieve economical transport of high-capacity IP traffic while providing high reliability in the optical-based core network, our research group has proposed a next-generation Internet backbone architecture called a multilayer service network architecture (MLSN). We have firstly developed a traffic engineering system based on MLSN architecture by implementing PCE providing multilayer path computation and path control. Dynamic multilayer IP/Optical topology reoptimization based on measured traffic was successfully demonstrated.
