Description
Claims (4)
- リンク障害がネットワーク内で起こるときに、データパケットについて再経路指定動作を実施する方法にして、
(a)ヘッドエンドHEノード(20)とテールエンドTEノード(23)との間でデータパケットを経路指定するステップと、
(b)データパケットがテールエンドノード(23)に達する前に、ヘッドエンドノード(20)とテールエンドノード(23)との間でリンク障害(27)を検出するステップと、
(c)ヘッドエンドノード(20)とテールエンドノード(23)との間のローカル修復点PLRノード(22)においてデータパケットを受信するステップと、
(d)PLRノード(22)のバイパストンネル(28)を通してヘッドエンドノード(20)にデータパケットを戻しそしてテールエンドノード(23)上に再経路指定するステップとを含む方法であって、さらに
(e)ヘッドエンドノード(20)が、ローカルバイパストンネル(29)を使用して、将来のデータパケットをテールエンドノードに搬送することを可能にするエラーメッセージを、PLRノード(22)からヘッドエンドノード(20)へ伝送するステップと、
