Title
(JA) コネクション管理ユニット、およびコネクション管理方法
Abstract
(JA)

遅延やパケットロスが発生した際にコンピュータシステムに障害またはフリーズを発生させないように、コンピュータバスのコネクション管理を行うコネクション管理機構およびコネクション管理方法を提供する。コネクション管理ユニットは、リクエスト元とリクエスト先との間でパケットを送信するコンピュータバスの通信に用いられるコネクション管理ユニットであって、上記リクエスト先から送信される返信パケットに遅延またはロスが発生した場合、ダミーの返信パケットを生成し上記リクエスト元へ送信するダミー返信パケット生成送信機能およびまたは、上記ダミーの返信パケットの送信後に上記リクエスト先から届いた正規の返信パケットを破棄するフィルタ機能、を有する。
