DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-ring network information management system, and more particularly to a multi-ring network information management system for a transmission communication device.

[0002]

2. Description of the Related Art In a conventional ring network information management system, a plurality of nodes (No.
When de) relates to a connected single ring network, the token shown in FIGS. 4A and 4B, or a token and a packet or one packet is transferred within the ring, as represented by a token ring system or the like. And manages and controls the information in the ring. Further, a plurality of rings were connected as shown in FIG.
Even in such cases, packets transferred within the ring
Or a single packet on another ring.

[0003]

This conventional token ring system uses a single packet of its own ring or another ring.
This is information management limited to information transfer , and in a multi-ring network in which two or more ring sub-networks are connected, it is difficult to simultaneously obtain node information in another plurality of ring sub-networks. In addition,
Congestion can easily occur when connecting between rings using
Will occur.

[0004] An object of the present invention is to be able to simultaneously manage node information in a plurality of other ring sub-networks in a multi-ring network in which two or more ring sub-networks are connected, and to prevent easy occurrence of congestion.
And a multi-ring network information management system.

[0005]

According to the present invention, there is provided an information management system in a multi-ring network in which two or more ring sub-networks are connected, a token indicating a transmission right, a ring ID unit indicating a unique value of a ring, Each node stores information of its own node in the packet portion of its own ring ID in an information block having a packet portion for storing information of each node, and if the node is shared with another ring, It is characterized in that node information is stored in the packet part of the ring ID and transferred within each ring.

According to the present invention, in an information management system in a multi-ring network in which two or more ring sub-networks are connected, a ring ID part indicating a unique value of a ring and a packet part storing information held by each node are provided. Each node stores the information of its own node in the packet part of its own ring ID in an information block that exists in one of the existing rings, and further, if the node is shared with another ring, the node information of the other ring is stored in the ring. It is stored in the packet portion of the ID and transferred within each ring.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of an example of a multi-ring network. Ring 1 and Ring 2
In each of the ring sub-networks, nodes 1, 2, 3, 4, 5 belong to ring 1, and nodes A, B, C, D, E belong to ring 2. Node 3 and node A are the same node, and node 4 and node E are the same node, and both belong to ring 1 and ring. That is, it is a common or shared node.

In such a multi-ring network, an information block having the configuration shown in FIG. 2 is transferred within a single ring. This information block includes a token 10 indicating a transmission right, a ring ID unit 20 indicating a unique value of the ring, and a packet unit 30 storing information of each node. (A) shows the case of a free token,
(B) shows a case of a busy token. In some cases, the token does not exist.

Each node stores its own information in its own ring ID.
If the node is stored in the packet unit 30 of the ring 20 and is shared with another ring, the node information of the other ring is stored in the packet unit 30 of the ring ID 20 and transferred to each ring.

In the case where a token exists, in the ring sub-network of ring 1, when an information block having a token is transferred, the nodes 1, 2, and 5 transmit a packet whose ring ID belongs to ring 1 and a token. It becomes possible when you have it. Further, the nodes 3 and 4 are enabled to have a packet whose ring ID belongs to ring 1 and a packet whose ring ID belongs to ring 2 when they have tokens.

Alternatively, when one token is not present and one information block is transferred in the ring sub-network of ring 1, the nodes 1, 2, 5 are placed in a predetermined storage position where the ring ID is less than ring 1. Transfer information of each node. Further, the common nodes 3 and 4 transfer the information of each node to a predetermined storage location where the ring ID is less than the ring 1 and the ring 2.

Similarly, also in the ring sub-network of ring 2, nodes B, C, and D store their own node information in the information area of ring 2 with the ring ID, and common nodes A and E store their own node information. Storing in the information area of ring 2 and storing information of ring 1 in the information area of ring 1;
Forward.

[0014]

The present invention described above, according to the present invention by incorporating a ring ID in the information block, to determine the node information in a plurality of other <br/> ring subnetwork simultaneously
Since the possible acquired, in a multi-ring network in which two or more rings subnetwork are connected, the node information in a plurality of other rings subnetwork simultaneously
Remarkably and the results that can be managed, easy occurrence of congestion in
Has results that can be prevented .
