Abstract

　伝送装置１００は、複数のパスをまとめたグループを一つのパスとして機能させ、そのグループに優先度が付与されたネットワーク回線を収容する伝送装置であって、故障したパスを他の正常なパスへ切り替える切替部１１５と、パスの故障を検出するアラーム検出部１１６ａおよび１１６ｂと、アラーム検出部１１６ａおよび１１６ｂにおいてパスの故障が検出された場合に、故障が検出されたパスを含むグループの帯域と、該グループに収容されている高優先度のネットワーク回線が必要とする帯域とを比較して切替部１１５の制御内容を判定する切替判定部１２５とを備え、収容されている高優先度の回線の品質を損なうことなく、グループに含まれるパスを動的に切り替えることを可能にする。
