Description

図８に示す管理テーブルには、一例としてノード１Ｂにおいて送信元のノード１ＡはＲＳＴＰ対応ノードとしてサポートされていることが示されている。なお、この管理テーブルの情報は、サポート表示が無くなった場合や、制御パケット自体を一定時間受信しなかった場合に管理テーブルから情報が削除される。 As an example, the management table shown in FIG. 8 indicates that the node 1A as the transmission source is supported as an RSTP-compatible node in the node 1B. The information in the management table is deleted from the management table when the support display disappears or when the control packet itself is not received for a certain period of time.

以上のように、この実施の形態３では、ＲＳＴＰを動作させる際には、制御パケットにＲＳＴＰサポート情報を付加して送信することで、受信側ではＲＳＴＰサポート情報を送信するノードの数を監視し、ＲＳＴＰ対応ノードが自ノードを含めて２ノードである場合は、ＲＰＲ機能処理部６はポイントツーポイント接続と見なして動作するので、ＲＳＴＰのハンドシェイク手順を適用することが可能となり、高速なトポロジ構築が可能となる。また、装置が自律的に判定するため、予め管理者が対向先を登録する必要が無く、運用が容易となる。 As described above, in the third embodiment, when RSTP is operated, RSTP support information is added to the control packet and transmitted, and the receiving side monitors the number of nodes that transmit the RSTP support information. When the RSTP-compatible node is two nodes including its own node, the RPR function processing unit 6 operates as a point-to-point connection, so that it is possible to apply an RSTP handshake procedure, and a high-speed topology Construction is possible. In addition, since the device autonomously determines, it is not necessary for the administrator to register the opposite destination in advance, and the operation becomes easy.

Claims

An RPR network that operates an STP in an RPR ring in which a plurality of nodes are connected via a double ring line, and the ring line is divided between the two nodes separately from the ring line. An RPR network system connected by a detour line for securing a detour route at times,
Each node stores means for transmitting the STP BPDU in a control packet defined by the RPR standard, and when receiving the control packet transmitted from another node, from the control packet An RPR network system comprising: a control packet transmission / reception unit including means for extracting a BPDU.

2. The RPR according to claim 1, wherein an STP processing unit that operates STP only in a node connected by the detour line is provided, and the control packet storing the BPDU is an OAM frame. Network system.

The RPR network system according to claim 1 or 2, wherein RSTP or MSTP is used instead of the STP.

An RSTP processing unit that operates RSTP is provided only in the node connected by the detour line, instead of the STP processing unit, and the control packet transmission / reception units of both nodes support RSTP in the control packet. RSTP support information indicating that this is added, means for reading RSTP support information from the control packet, and a node that supports RSTP based on a management table for managing the presence or absence of RSTP support for each node. Means for determining whether or not there are two nodes including the node, and if the nodes supporting RSTP by this determination means are two nodes including the own node, the nodes adjacent to each other are regarded as point-to-point connections. It is characterized by exchanging each BPDU by performing a handshake operation. RPR network system according to claim 2,.

5. The RPR network system according to claim 4, wherein MSTP is used instead of RSTP.
