Description

本発明はネットワーク情報を用いた利用者間接続サービスシステムに関するものである。 The present invention relates to an inter-user connection service system using network information.

図１は、従来のサーバを用いた情報通信システムの例を示す図である。
従来のサーバを用いた情報通信システムは、情報提供者１の情報通信端末１６と、情報提供者２の情報通信端末１７と、情報利用者３の情報通信端末１８と、情報利用者４の情報通信端末１９と、キャリアネットワーク或いはＩＳＰ網１４と、該キャリアネットワーク或はＩＳＰ網１４内のエッジルータ２３，２２，２４，２５と、情報提供者１，２や情報利用者３の情報通信端末１６，１７，１８などの利用者端末を最寄りのエッジルータ２２，２３，２４に接続するアクセス網１５ｂ，１５ａ，１５ｃと、利用者間の接続サービスを実行するサーバ２１とからなる。 FIG. 1 is a diagram illustrating an example of an information communication system using a conventional server.
The information communication system using the conventional server includes the information communication terminal 16 of the information provider 1, the information communication terminal 17 of the information provider 2, the information communication terminal 18 of the information user 3, and the information user 4 information. The communication terminal 19, the carrier network or ISP network 14, the edge routers 23, 22, 24, 25 in the carrier network or ISP network 14, and the information communication terminals 16 of the information providers 1, 2 and the information user 3 , 17, 18 and the like, and the access networks 15b, 15a, 15c for connecting the user terminals to the nearest edge routers 22, 23, 24, and a server 21 for executing a connection service between users.

このようなサーバ２１を用いた従来のサーバ方式では、例えばサーバ２１が東京にあった場合、サーバ２１を機軸に見て最適な相手と接続するので、京都の情報利用者３の情報通信端末１８からの接続要求に対しては、サーバ２１から見て応答性の良い横浜の情報提供者２の情報通信端末１７との接続が与えられることになる。このため、京都の情報利用者３の情報通信端末１８から見て応答性の良い大阪の情報提供者１の情報通信端末１６との接続を保証できるものではなかった。また、サーバ２１を介した接続では、横浜の情報提供者２の情報通信端末１７は、東京にあるサーバ２１を経由し、京都の情報利用者３の情報通信端末１８との接続になってしまい、エッジルータ２５での輻輳、サーバ２１の負荷集中などにより必ずしも最適な通信環境の相手との接続が可能ではなかった。また、サーバの接続要求が増えるとサーバ２１での処理負荷が大きくなる等の間題が発生していた。且つ多くの機能を一箇所のセンターサーバ上におくことは、センターサーバでの故障や輻輳やＤｏＳ（Denial of Service）攻撃などの情報提供サービス耐性にリスクがあり、その一箇所の障害がシステム全体の停止に波及しやすい状況があった。従来には、情報提供者と情報利用者の接続をエンドーエンド間にて最適な相手と接続するサービスシステムは無かった。 In the conventional server system using such a server 21, for example, when the server 21 is in Tokyo, the server 21 is connected to the most appropriate partner as seen from the axis, so the information communication terminal 18 of the information user 3 in Kyoto. Is connected to the information communication terminal 17 of the information provider 2 in Yokohama, which has good responsiveness when viewed from the server 21. For this reason, the connection with the information communication terminal 16 of the information provider 1 in Osaka, which has good responsiveness when viewed from the information communication terminal 18 of the information user 3 in Kyoto, cannot be guaranteed. Further, in the connection via the server 21, the information communication terminal 17 of the information provider 2 in Yokohama is connected to the information communication terminal 18 of the information user 3 in Kyoto via the server 21 in Tokyo. Due to congestion at the edge router 25, load concentration on the server 21, etc., connection with a partner in an optimum communication environment has not always been possible. Further, when the number of server connection requests increases, a problem arises that the processing load on the server 21 increases. In addition, placing many functions on a single center server has a risk of failure in the center server, congestion, information resistance service resistance such as a DoS (Denial of Service) attack, and the failure at that single point is the entire system. There was a situation that could easily spread to the stoppage. Conventionally, there has been no service system for connecting an information provider and an information user with an optimal partner between end-to-end.

Is disclosed.
However, this information communication system is not configured to determine a connection partner by looking at traffic information in the network.

しかし、このネットワークでは、イベント受信者が受信を希望するイベントの意味情報をネットワークに登録し（これをフィルタという）、フィルタが発火したとき（登録した意味情報がイベント送信者が送信したイベントと一致したとき）、対応するイベント受信者の端末を接続先と決定する構成になっており、トラフィック情報をみて決めることはできない。 Japanese Laid-Open Patent Publication No. 2002-94561 (Patent Document 2) is an information communication system that distributes an event including semantic information and data, and determines a delivery destination of the event based on the content of the semantic information. A semantic information network for delivering the event to a determined delivery destination is disclosed.
However, in this network, the event receiver registers the semantic information of the event that the event recipient wants to receive (this is called a filter), and when the filter fires (the registered semantic information matches the event sent by the event sender) The corresponding event receiver's terminal is determined as the connection destination, and cannot be determined by looking at the traffic information.

また、特開２００１−６９１７０号公報（特許文献３）には、インターネット内の一部の通信に品質が保証されていない通信網において、通信網のトラフィックや品質を計測し、計測したデータを元に品質を評価し、評価結果に基づいて該通信網の品質を予測し、予測結果を該通信網を介して利用者に提示するネットワーク情報システムが開示されている。ユーザは提示された予測品質を見てサービスクラスを選択する。 Japanese Patent Laid-Open No. 2001-69170 (Patent Document 3) discloses a method for measuring traffic and quality of a communication network in a communication network in which quality is not guaranteed for a part of communication in the Internet, and based on the measured data. A network information system that evaluates quality, predicts the quality of the communication network based on the evaluation result, and presents the prediction result to the user via the communication network is disclosed. The user selects a service class based on the presented predicted quality.

According to the system of the present invention, the information provider only receives the information input form corresponding to the virtual portal site from the nearest edge node, inputs the provided information to the information input form corresponding to the virtual portal site, and transmits it. Thus, the edge node nearest to the information provider distributes the network information between the edge nodes nearest to the information provider's information communication terminal and the information provider's information communication terminal together with information provided by the information provider to all edge nodes. The information user receives the information input form corresponding to the virtual portal site from the nearest edge node, inputs the usage information into the information input form corresponding to the virtual portal site, and transmits it. The nearest edge node detects the network information between the information communication terminal of the information user and the nearest edge node. The information provider is determined and connected based on the provided information and usage information, the network information between the information user and the nearest edge node, and the network information between the information provider and the nearest edge node.
