Abstract
The present invention relates to a kind of secondary node to repair failure loop network implementation method, this method increases a secondary node when loop network is disposed, secondary node is connected in loop network, and the number of links of secondary node and loop network is more than or equal to one, less than or equal to existing number of nodes.In loop network normal work, secondary node is in wave-off state, only when existing node breaks down in loop network, secondary node can add to form standby loop network to realize that network signal continues to transmit with newcomer's node, after existing node failure is repaired, secondary node exits loop network and recovers wave-off state.
Description
Technical field
Patent of the present invention is related to computer network communication field.
Background technology
Loop network is that every equipment is linked together using a continuous ring.It can ensure to send out in an equipment
The signal sent can all be seen by other all equipment on ring.In simple ring network, the damage of any part in network
It will all cause system to break down, will so hinder whole system to carry out normal work.And the ring network with higher structure is then
Largely improve this defect.The latticed form of this structure is mainly used in Token Ring, in this network knot
Each equipment is directly concatenated by cable in structure, eventually forms a closed loop, the information that whole network is sent is exactly at this
Transmitted in individual ring, this kind of network is generally referred to as " token-ring network ".
Ring type structure is on the lan using more.Transmission media in this structure is used from an end subscriber to another end
Family, it is ring-like until all end subscribers are linked to be, as shown in Figure 1.Centering when this structure obviously eliminates end subscriber communication
Feel concerned about the dependence of system.The characteristics of ring type structure is that each end subscriber is connected with two adjacent end subscribers, thus there is
Point-to-point link, but always operated with one way system, then just there is the title of upstream end subscriber and downstream end subscriber.Such as user N
It is user N+1 upstream end subscriber, N+1 is N downstream end subscriber.If N+1 ends need to transmit data to N-terminal, almost
N-terminal is got to around ring within one week.One example of ring network is token ring LAN, and this network structure is earliest by IBM
Release, but used before by other producers.In token-ring network, possessing the equipment of " token " allows to transmit number in a network
According to.It can so ensure only have an equipment to transmit information in sometime interior network.
Any information transmitted on ring all has to pass through all end points, therefore, if the certain point of ring disconnects, owns on ring
Communication between end will terminate.To overcome the fragility of this network topology structure, each end points also connects in addition to being connected with a ring
It is connected on standby ring, when main ring failure, is automatically brought on standby ring, and the deployment way of this standby ring not only adds portion
Complexity is affixed one's name to, while each node need to be connected to two loop networks.
Patent of invention content
Patent of the present invention is related to a kind of secondary node and repairs failure loop network implementation method, and this method is when loop network is disposed
Increase a secondary node, secondary node is connected in loop network, and the number of links of secondary node and loop network is big
In equal to one, less than or equal to existing number of nodes.In loop network normal work, secondary node is in wave-off state,
Only when existing node breaks down in loop network, secondary node can add to form standby loop network with newcomer's node
To realize that network signal continues to transmit, when existing node failure is repaired after, secondary node exits loop network and recovers not receive
Signal condition.
Brief description of the drawings
Fig. 1 is that a kind of secondary node of patent of the present invention repairs failure loop network implementation method structural representation.
