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. The host communication unit H and the device communication unit D of the node device 1 share a wireless transmission / reception unit. Since the switch unit S can transfer the IP packet and the wireless USB packet, the node device 1 and the IP terminal 3 can perform IP connection. Further, any peripheral device 2 can be connected and used via a communication network. The switch unit S constitutes an L3 switch, and includes two FDBs (Forwarding DataBase) for IP communication and wireless USB communication. The IP packet and wireless USB packet received from each port are compared with each FDB and the like. It will be transferred to another port.
ノード装置1は、自己の識別情報などをクラスタ識別情報とし、該クラスタ識別情報および自己のデバイス通信部Dが参加したクラスタのクラスタ識別情報を含むビーコンを自己のホスト通信部Hから他のノード装置1に向けてブロードキャスト送信させるとともに、他のノード装置1から受信したビーコンを基に自己のデバイス通信部Dを参加させるクラスタを選んでそこに参加させて、自己を含む3つのノード装置1が連環する様に制御する。具体的には、ノード装置1aの場合に、受信したビーコンを基に一方のデバイス通信部Dが、自己を含む3つのノード装置1が連環をなす条件に該当するノード装置1bが構築したクラスタを選んで参加し、自己を含む3つのノード装置1a、1b、1cを連環させるとともに、受信したビーコンを基に他方のデバイス通信部Dが自己を含む3つのノード装置1が、連環をなす条件に該当するノード装置1dが構築したクラスタを選んで参加し、自己を含む3つのノード装置1a、1b、1dを連環させることとなる。ここで、ノード装置1は、自己を含む3つのノード装置1が連環を構成する適当なクラスタが見当たらない場合に、自己が接続していない他のノード装置1が構築した任意のクラスタを見付けてそこに参加することとなる。 The node device 1 uses its own identification information or the like as cluster identification information, and sends a beacon including the cluster identification information and the cluster identification information of the cluster to which its device communication unit D participates from its own host communication unit H to another node device. 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.
