Background technology
Utilize MSTP (MultipleSpanningTreeProtocol, Multiple Spanning Tree Protocol) loop network can be pruned and become an acyclic tree network, avoid the hyperplasia of message in loop network and Infinite Cyclic, additionally provide multiple redundant paths of data retransmission simultaneously, in data forwarding process, realize the load balancing of vlan data.Compatible STP and RSTP of MSTP, and the defect of STP and RSTP can be made up.It both can Fast Convergent, and the flow of different VLAN also can be made along the distribution of respective path, thus provided better load balancing mechanism for redundant link.
When connecting after somewhere disconnects or disconnects appears in circuit again, exchange opportunity inside the network of place utilizes the switch in MSTP Protocol Through Network to carry out loop pruning again, the repair time of such network can be longer, at some to the power industry having strict demand repair time, do not reach the requirement of regulation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of MSTP communication network and the self-repairing method thereof with automatic repair function, is intended to, when connecting after network disconnects or disconnects, repair fast to the tree network under MSTP agreement again.
The present invention is achieved in that the self-repairing method of MSTP communication network, and described MSTP communication network comprises host exchange and some from switch; Host exchange and between switch by MSTP protocol interaction, be connected to form acyclic tree network, between each node of described tree network, have main line and extension wire simultaneously; Tree-like information the described MSTP agreement current separately from switch record;
Described self-repairing method comprises the steps:
Step a, when there is broken string from the main line of switch, according to the tree-like information under the MSTP agreement that oneself is current, sends the information of startup extension wire to host exchange;
Step b, host exchange starts the extension wire from switch that broken string occurs after receiving log-on message, realizes the tree network under reparation MSTP agreement.
Further, the tree-like information under described MSTP agreement comprises connectivity port information and the state information of the switch of up-downgoing.
Present invention also offers a kind of MSTP communication network with automatic repair function, described MSTP communication network comprises host exchange and some from switch; Host exchange and between switch by MSTP protocol interaction, be connected to form acyclic tree network, between each node of described tree network, have main line and extension wire simultaneously;
Describedly be used for when broken string occurs its main line from switch, according to the tree-like information under the current MSTP agreement of oneself record, send and start the information of extension wire to described host exchange; Described host exchange is used for after receiving log-on message, start the extension wire from switch that broken string occurs, and the tree network under MSTP agreement is repaired in realization.
Further, the tree-like information under described MSTP agreement comprises connectivity port information and the state information of the switch of up-downgoing.
The present invention compared with prior art, beneficial effect is: the invention provides a kind of MSTP communication network and the self-repairing method thereof with automatic repair function, utilize existing MSTP agreement, form stable acyclic tree network, the switch in tree network records the connectivity port information under current MSTP agreement automatically; And when connecting again after network disconnects or disconnects, according to the connectivity port information of record, fast the tree network under MSTP agreement being adjusted, accelerating the reparation speed of network.
Accompanying drawing explanation
Fig. 1 is the tree network structure schematic diagram under the MSTP agreement that provides of the embodiment of the present invention;
Fig. 2 is the tree network self-repairing method flow chart under the MSTP agreement that provides of the embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The fast repairing method of introduction of the present invention and system are based on MSTP agreement, wherein, multiple spanning tree (MST) uses rapid spanning-tree (RSTP) agreement revised to be called Multiple Spanning Tree Protocol (MSTP, Multi-ServiceTransferPlatform); MSTP (multi-service transport platform based on SDH) refer to realize the business such as TDM, ATM, Ethernet based on SDH platform simultaneously access, process and transmission, the multi-service node of united net management is provided.
Invention describes a kind of self-repairing method of MSTP communication network, as shown in Figure 1, described MSTP communication network comprises host exchange 1 and some from switch 2; Host exchange and between switch by MSTP protocol interaction, be connected to form stable acyclic tree network, between each node of described tree network, have main line and extension wire simultaneously; After tree network is stable, described from the tree-like information the switch 2 MSTP agreement that record is current separately automatically; Tree-like information under described MSTP agreement comprises connectivity port information and the state information of the switch of up-downgoing;
As shown in Figure 2, described self-repairing method comprises the steps:
Step a, when there is broken string from the main line of switch, according to the tree-like information under the MSTP agreement that oneself is current, sends the information of startup extension wire to host exchange;
Step b, host exchange starts the extension wire from switch that broken string occurs after receiving log-on message, realizes the tree network under reparation MSTP agreement.
Present invention also offers a kind of MSTP communication network with automatic repair function, described MSTP communication network comprises host exchange 1 and some from switch 2; Host exchange 1 and between switch 2 by MSTP protocol interaction, be connected to form stable acyclic tree network, between each node of described tree network, have main line and extension wire simultaneously;
