Title:
メトリック・ルーテッド・ネットワーク内でトラフィック・エンジニアリングを実行する方法とシステム
Document Type and Number:
Japanese Patent JP2006503506
Kind Code:
A
Abstract:
A system (10), to migrate a shortest-path-first (SPF) routed network from a first routing state to a second routing state, includes a changeover module (135) to generate a sequence of intermediate network plans, each of which modifies a preceding network state according to a preceding network plan, such that a routing of at least one demand in the network changes. The sequence of intermediate network plans migrates the network from the first routing state to the second routing state. A network controller (105) sequentially configures the network according to the sequence of intermediate network plans to migrate the network from the first routing state to the second routing state. Each intermediate network plan of the sequence configures the network to operate within at least one predetermined constraint.
