以下、本発明の実施の一形態について詳細に説明する。   Hereinafter, an embodiment of the present invention will be described in detail.

図１は実施形態の通信ネットワークシステムの構成図である。通信ネットワークシステムは、クラスタ（図１の点線内）を構築するワイヤレスＵＳＢのホスト通信部Ｈ、クラスタに参加する少なくとも１つ以上のワイヤレスＵＳＢのデバイス通信部Ｄ、ＩＰパケット及びワイヤレスＵＳＢパケットを送受信する図示させていない情報処理部、および各ポートがホスト通信部Ｈとデバイス通信部Ｄと情報処理部に繋がり、ＩＰパケット及びワイヤレスＵＳＢパケットを受信して他のポートへ転送するスイッチ部Ｓを備えるノード装置１と、デバイス通信部Ｄを備え、該デバイス通信部Ｄを介してワイヤレスＵＳＢパケットを送受信する周辺装置２と、デバイス通信部Ｄを備え、該デバイス通信部Ｄを介してＩＰパケット及びワイヤレスＵＳＢパケットを送受信するＩＰ端末３と、から構成され、ノード装置１が複数存在し、１つのクラスタに少なくとも１つ以上のデバイス通信部Ｄが参加可能であり、ノード装置１のデバイス通信部Ｄが他のノード装置１のホスト通信部Ｈが構築したクラスタに参加してクラスタ内通信を行うことで、クラスタ同士が網目構造に接続された通信ネットワークを構築し、周辺装置２とＩＰ端末３のデバイス通信部Ｄが何れか１つのクラスタに参加してクラスタ内通信を行い、クラスタ内で複数のノード装置１、周辺装置２およびＩＰ端末３が共存する。   FIG. 1 is a configuration diagram of a communication network system according to an embodiment. The communication network system transmits / receives a wireless USB host communication unit H that constructs a cluster (within the dotted line in FIG. 1), at least one wireless USB device communication unit D that participates in the cluster, an IP packet, and a wireless USB packet. An information processing unit (not shown) and a node having each port connected to the host communication unit H, device communication unit D, and information processing unit, and a switch unit S that receives IP packets and wireless USB packets and transfers them to other ports A peripheral device 2 that includes a device 1 and a device communication unit D and that transmits and receives wireless USB packets via the device communication unit D, and a device communication unit D that includes an IP packet and a wireless USB via the device communication unit D An IP terminal 3 for transmitting and receiving packets, and a node device Are present, at least one device communication unit D can participate in one cluster, and the device communication unit D of the node device 1 participates in a cluster constructed by the host communication unit H of the other node device 1. By performing intra-cluster communication, a communication network in which the clusters are connected to each other in a network structure is constructed, and the device communication unit D of the peripheral device 2 and the IP terminal 3 participates in any one cluster and performs intra-cluster communication. And a plurality of node devices 1, peripheral devices 2 and IP terminals 3 coexist in the cluster.

ノード装置１、周辺装置２、ＩＰ端末３などの装置は、ＣＰＵ、ＲＯＭ、ＲＡＭなどを有するコンピュータ部と、共通のコネクション鍵を備えている。ノード装置１のホスト通信部Ｈとデバイス通信部Ｄは無線送受信部を共有している。ノード装置１とＩＰ端末３は、スイッチ部ＳがＩＰパケット及びワイヤレスＵＳＢパケットを転送することができるため、ＩＰ接続を行うことができる。また、通信ネットワークを介して任意の周辺装置２を接続して利用することができる。スイッチ部Ｓは、Ｌ３スイッチを構成し、ＩＰ通信用とワイヤレスＵＳＢ通信用の２つのＦＤＢ（Forwarding DataBase）などを備え、各ポートから受信したＩＰパケットとワイヤレスＵＳＢパケットを夫々のＦＤＢなどに照らして他のポートへ転送することとなる。   Devices such as the node device 1, the peripheral device 2, and the IP terminal 3 have a common connection key and a computer unit having a CPU, a ROM, a RAM, and the like.

In addition to the broadcast transmission toward the node 1, a cluster in which its own device communication unit D participates is selected based on the beacon received from the other node device 1, and the three node devices 1 including itself are linked together. Control as you do. Specifically, in the case of the node device 1a, based on the received beacon, one device communication unit D creates a cluster constructed by the node device 1b corresponding to the condition that the three node devices 1 including itself are connected. Select and participate to link the three node devices 1a, 1b, and 1c including the self, and based on the received beacon, the other device communication unit D includes the three node devices 1 including the self as a condition to form a link. The cluster constructed by the corresponding node device 1d is selected and joined, and the three node devices 1a, 1b, and 1d including itself are linked. Here, the node device 1 finds an arbitrary cluster constructed by another node device 1 to which the node device 1 is not connected, when an appropriate cluster in which the three node devices 1 including the device itself are connected is not found. You will be there.

課題を解決するために本発明のクラスタ構築ノードは、クラスタを構築するクラスタ構築ノードであって、三つの前記クラスタ構築ノードによる環状接続部の内の二つの前記クラスタ構築ノードを含む三つの前記クラスタ構築ノードが二つの前記クラスタにより繋がるように、前記クラスタに参加させる手段を備えることを特徴とする。   In order to solve the problem, the cluster building node according to the present invention is a cluster building node for building a cluster, and includes the three cluster building nodes including two of the cluster building nodes in a circular connection portion formed by the three cluster building nodes. The construction node includes means for joining the cluster so that the construction node is connected by the two clusters.

ところで、従来のクラスタ通信システムは、アドホックに形成されているが各クラスタがツリー状に接続されているため効率的な通信経路を構築することができないと言った問題があった。また、クラスタを構築するクラスタ構築ノードが三つのクラスタ構築ノードによる環状接続部の二つが二つのクラスタ構築ノードを共有して繋がるように、クラスタに参加させることができないと言った問題があった。   By the way, the conventional cluster communication system is ad-hoc, but there is a problem that an efficient communication path cannot be constructed because each cluster is connected in a tree shape. In addition, there is a problem that a cluster building node that builds a cluster cannot participate in the cluster so that two of the circular connection parts formed by the three cluster building nodes can share and connect the two cluster building nodes.

そこで、本発明の目的は、三つのクラスタ構築ノードによる環状接続部の二つが二つのクラスタ構築ノードを共有して繋がるように、クラスタに参加させるクラスタ構築ノードを提供することにある。   Accordingly, an object of the present invention is to provide a cluster construction node that participates in a cluster so that two of the circular connection sections formed by the three cluster construction nodes are connected to share the two cluster construction nodes.

本発明によれば、クラスタ構築ノードは、三つのクラスタ構築ノードによる環状接続部の二つが二つのクラスタ構築ノードを共有して繋がるように、クラスタに参加させることができる。   According to the present invention, the cluster building node can participate in the cluster such that two of the circular connection units of the three cluster building nodes are connected to share the two cluster building nodes.

本発明は、クラスタ構築ノードに関する。   The present invention relates to a cluster building node.
