Description
本出願は、出願人が本出願と共に出願した同時係属中の「Bootstrapping in peer−to−peer networks with network address translators」という表題の米国特許出願に関連し、この米国特許出願は、ここでの言及をもって本明細書に組み入れられたものとする。
図2は、代表的な部分メッシュ・オーバーレイ50を示しており、この例では、各ピア12は、制限的なフィルタリングポリシーを有するNAT(図示せず)の裏に配置されている。一般に、オーバーレイ50内の各ピア12は、いくつかの他のピア12と接続(実線で示す)を確立し、ピア12間接続の部分メッシュを確立する。部分メッシュ・オーバーレイ50を生成すると、次に、ピア12は確立された接続を用いてメッセージをルーティングする。一度、確立されると、少なくとも1つのピアによって望まれる限り、接続が保持される。接続の保持は、通常、何らかのメッセージの周期的な交換を必要とする。
図3は、図1のサブネット14の例示的な配置80を示す。サブネット14は、いずれもNAT30の裏に配置されたピア12の集団を含む。この種類のトポロジーでは、サブネット14内の1つまたは複数のピア12が、サブネット14内の他のピア12の代わりに動作する代表的なピア12Rとして「選出され」るか、「指名され」得る。
構造化されたスキームは、ルーティングに活用され得る接続パターンを生成する。例えば、構造化されたメッセージルーティングは、DHT(分散ハッシュテーブル)ルックアップスキームのルーティングアルゴリズムへの「変換」に基づいてもよい。特に、データアイテムを調べるためのDHTスキームは、データを保持するピアへのルーティングのスキームと見なされる。ルーティングが検索されるノードのピア識別子に基づく場合、プロセスは、ルーティングアルゴリズムと考えることが可能である。
図3を見ると、ピア12Aは、最初はネットワーク全体の一部でない。ピア12Aのネットワークへの結合を可能にするプロセス100が、図5のフローチャートに関連して説明される。
図6は、本発明の実施形態による、ネットワークアドレス・トランスレータ(NAT)の存在下でピアツーピア(P2P)ネットワーク内でのピア間通信を可能にするための方法200を示すフローチャートである。方法200が含むのは:
ステップ210:例えば、1方向ハッシュ関数215を用いて、P2Pネットワーク内の複数のピアの各々に固有のピア識別子を割当てる。
