Description
本願は、2013年9月23日に出願された米国特許出願シリアル番号第14/034,478号の利益を主張する。その開示は、その全体がここに引用により援用される。
ここに説明される主題は、Diameterメッセージを処理するための方法およびシステムに関する。より特定的には、ここに説明される主題は、電気通信ネットワーク内でDiameter負荷および過負荷情報を管理するための方法、システム、およびコンピュータ読取可能媒体に関する。
Diameterとは、コンピュータネットワーク用の認証、認可およびアカウンティング(authentication, authorization and accounting:AAA)プロトコルであり、RADIUSの後継版である。Diameterベースのプロトコルは、インターネット特別技術調査委員会(International Engineering Task Force:IETF)のコメント要求(request for comments:RFC)6733に規定されており、それはその全体がここに引用により援用される。Diameterメッセージは、ユーザごとのフレームワークを使用しており、要求−回答メッセージのフォーマットで存在する。Diameter回答メッセージは、ホップバイホップ伝送を使用して要求メッセージがルーティングされたのと同じ経路を介して、要求元に戻る。
一局面によれば、ここに説明される主題は、ネットワーク仮想化を管理するために過負荷情報を使用するための方法を含んでいてもよい。この方法は、ハードウェアプロセッサを含む、電気通信ネットワーク内の仮想ネットワークを管理するための仮想化オーケストレータ(virtualization orchestrator:VO)で、過負荷情報を受信することと、受信された情報に基づいて、行なうべきネットワーク仮想化動作を判断することと、ネットワーク仮想化動作を行なうこととを含んでいてもよい。
ここに開示された主題に従って、電気通信ネットワーク内でDiameter負荷および過負荷情報を管理するために、システム、方法、およびコンピュータ読取可能媒体が提供される。
