Abstract

　　ＭＰＬＳレイヤとＰＷレイヤの相関を有する機能を提供することで、ＭＰＬＳレイヤの情報をＰＷレイヤに通知可能とした方式を提供する。ＭＰＬＳ（Ｍｕｌｔｉ　Ｐｒｏｔｏｃｏｌ　Ｌａｂｅｌ　Ｓｗｉｔｃｈｉｎｇ）トンネリングならびにラベル技術を用いて通信サービスをＭＰＬＳにマッピングし、エンド・トゥ・エンドで双方向サービスを提供する伝送方式であって、双方向サービスのためのラベルの割り振り制御を行う手段と、この割り振り制御が終了した後に、その割り振り制御に用いたＬＤＰメッセージをペイロードとし、双方向サービスが用いるトンネル向けラベルＬ２をヘッダとするメッセージを送出する手段と、このメッセージを終端する側においては、受信した割り振り制御に用いたＬＤＰメッセージをもとに、該当メッセージに含まれるサービス向けのラベルＰ１と受信したトンネル向けラベルＬ２とを関連づける手段と具備するを特徴とする通信方式である。
