The present invention is directed to the problems referred to above, proposed solution.
Fig. 2 shows the indicative flowchart of the method 100 detecting for business looped network of the embodiment of the present invention, and the method 100 for example can be carried out by first node, and as shown in Figure 2, the method 100 comprises:
S110, determines that first node receives the number of times of the detection messages forwarding according to service path, and whether this detection messages exists looped network for detection of this service path through this first node;
S120, in the time that this number of times exceedes first threshold, determines that this service path exists looped network.
Therefore, the method detecting for business looped network of the embodiment of the present invention, whether the number of times of the detection messages forwarding according to service path receiving by judgement exceedes first threshold, can determine whether this service path exists looped network, looped network can effectively be detected, so that rapid damage looped network, can effectively improve the reliability of network.
The service path that should be understood that this first node of process in the embodiment of the present invention refers to, through a service path of first node, or the specific transactions path of process first node.
Will also be understood that, detection messages in the embodiment of the present invention is to forward according to the service path through this first node, particularly, taking the service path shown in the dotted line of the middle left side of Fig. 1 (a) as example, if node 1 sends this detection messages to node 2, node 2 is receiving after this detection messages and can send this detection messages to node 3; Again taking the service path shown in Fig. 1 (b) as example, if node 1 sends this detection messages to node 2, node 2 can send to node 3 after receiving this detection messages, node 3 is receiving after this detection messages and can send to node 4, this detection messages that receives node 4 can continue to send to node 2, because the service path shown in Fig. 1 (b) forms looped network between node 2, node 3 and node 4, therefore this detection messages forwarding that can circulate between node 2, node 3 and node 4.The routing direction that should also be understood that this detection messages can be consistent with Business Stream, also can be contrary, and the embodiment of the present invention is not construed as limiting this.
In addition,, for the ease of this detection messages of node recognition, this detection messages can be the unicast message that carries the mark of service path.
Alternatively, as an embodiment, in the method 100 shown in Fig. 2, this detection messages is the unicast message that carries the mark of this service path.
Particularly, unicast message is relative broadcasting packet, taking the service path shown in Fig. 1 (b) as example, in the time that node 1 sends this detection messages, only send to node 2, or only send to node 3, instead of send to node 2 and node 3, neither broadcast transmission. simultaneously simultaneously
In S110, determine that first node receives the number of times of the detection messages forwarding according to service path, wherein, this detection messages that this first node receives can be generated and sent by any one node in service path.Taking first node corresponding to the node 2 in Fig. 1 (b) as example, this detection messages can be generated by the node 1 outside looped network, and sends to node 2 or node 3; This detection messages also can be generated by any node in the node 2 in looped network, node 3 or node 4, and sends to the next node in service path, and the embodiment of the present invention is not construed as limiting this.Therefore, this detection messages that the first node in the embodiment of the present invention receives can be that this first node generates, and can be also that other nodes in service path generate.
Alternatively, as an embodiment, in the method 100 shown in Fig. 2, the method also comprises:
Generate this detection messages;
Send this detection messages to the Section Point adjacent with this first node in this service path, so that this Section Point sends this detection messages to the next node in this service path;
Receive this detection messages that the 3rd node adjacent with this first node in this service path sends;
Wherein, this Section Point and the 3rd node are different nodes.
Particularly, the node 2 taking this first node as Fig. 1 in (b) is example, and node 2 generates this detection messages, sends this detection messages to node 3; Node 3 sends this detection messages to node 4 after receiving this detection messages; Node 4 receives after this detection messages, then sends this detection messages to node 2, and node 2 is sending after detection messages to node 3, receives this detection messages again from node 4.Should be understood that first node in the embodiment of the present invention can be corresponding to the node 2 in Fig. 1 (b), correspondingly, Section Point can be corresponding to the node 4 in Fig. 1 (b) corresponding to node 3, the three nodes in Fig. 1 (b).
Should be understood that in embodiments of the present invention, this first node generates this detection messages, for example, can configure this first node by user and generate this detection messages, also can generate this detection messages by this first node of system definition, and the embodiment of the present invention is not construed as limiting this.
Alternatively, as an embodiment, in the method 100 shown in Fig. 2, the method also comprises:
Receive this detection messages that the 4th node adjacent with this first node in this service path sends;
Send this detection messages to the 5th node adjacent with this first node in this service path, so that the 5th node sends this detection messages to the next node in this service path;
Wherein, the 4th node and the 5th node are different nodes.
Particularly, the node 2 taking this first node as Fig. 1 in (b) is example, and the 4th node can be corresponding to the node 1 in Fig. 1 (b) or node 3 or node 4.Particularly, when the 4th node is during corresponding to node 1, the 5th node can be corresponding to node 3 or node 4, for example, node 1 generates this detection messages, and sends to node 2, node 2 sends to node 3 after receiving this detection messages, node 3 receives after this detection messages, sends to node 4, and node 4 receives detection messages and sends to node 2 again.Or, when the 4th node is during corresponding to node 3, the 5th node can be corresponding to node 4, for example, node 3 generates this detection messages, and sends to node 2, node 2 sends to node 4 after receiving this detection messages, node 4 receives after this detection messages, sends to node 3, and node 3 receives detection messages and sends to node 2 again.
Should be understood that in embodiments of the present invention, this first node can not generate detection messages, only forwards this detection messages.
In S120, in the time that this number of times exceedes first threshold, determine that this service path exists looped network.For example, when in this detection messages of service path repeating shown in Fig. 1 (b), this detection messages finally can forward between node 2, node 3 and node 4 in circulation, at this moment the number of times that any one node in node 2, node 3 and node 4 receives this detection messages all can exceed first threshold, for example 3 times; In the time confirming that number of times exceedes first threshold, can determine in this path and have looped network.
In embodiments of the present invention, detection messages forwards according to service path, and therefore, when service path exists looped network, this detection messages finally can forward between at least three nodes in circulation, and also between the included all nodes of this looped network, circulation forwards.Correspondingly, the each node in looped network can be determined the number of times that receives separately detection messages and exceed first threshold, therefore can have looped network by this service path of fast detecting.Therefore, the method for detection of business looped network that the embodiment of the present invention provides, can detect the looped network existing in service path effectively rapidly.
Should understand, first threshold in the embodiment of the present invention, can be that user is self-defined according to type of service or network condition, and for example this threshold value can be 2 times, also can be more than 3 times or 3 times, for example,, in the time that service path configuration changes, although do not cause service path to occur looped network, but may cause same detection messages is 2 times through the number of times of first node, under this scene, for example is avoided erroneous judgement, need this first threshold to be defined as at least 3 times.This first threshold also can be by system according to situation and scene are specifically definite particularly, and embodiment of the present invention contrast is not construed as limiting.
When definite service path exists after looped network, disconnect this looped network by relevant treatment.
Alternatively, as an embodiment, the method also comprises:
Send the first message that is used to indicate this service path and exists looped network to webmaster;
Receive the second message that this webmaster sends according to this first message, this second message is used to indicate this first node and disconnects this looped network;
According to this second message, disconnect this looped network.
Particularly, taking Fig. 1 (b) as example, for the node 2 in looped network, node 3 and node 4, the number of times that receives detection messages all can exceed first threshold, and node 2, node 3 and node 4 can report this first message to webmaster; Webmaster can, according to the first message receiving, be determined the destination node that disconnects this looped network, and for example this destination node is node 2, and webmaster sends this second message to node 2; Node 2, according to this second message, disconnects this looped network.First node in the embodiment of the present invention can be corresponding to the node 2 in Fig. 1 (b).
Should be understood that this is used to indicate this service path and exists the first message of looped network can be referred to as looped network warning message.
Should also be understood that the first node in the embodiment of the present invention can also be corresponding to the node 3 in Fig. 1 (b) or node 4.
Alternatively, as an embodiment, the method also comprises:
When determining that the configuration of this first node automatically shuts down while enabling, disconnects this looped network.
Particularly, user can configure loopback and automatically shut down and enable on this first node, determines while there is looped network through the path of first node when this first node, disconnects this looped network at this first node.
Should be understood that in embodiments of the present invention, first node disconnects this looped network, particularly, this first node can by and service path in next node between communication port go to enable, disconnect looped network.Particularly, as shown in Figure 4, node 2, node 3 and node 4 have formed the looped network in service path, and node 2 can, by port P7 is gone to enable, disconnect this looped network.In the embodiment of the present invention, disconnect looped network and can also adopt the additive method of interrupt network in prior art to realize, the embodiment of the present invention is also made particular determination.
In sum, in embodiments of the present invention, the number of times of the detection messages forwarding according to service path receiving by judgement exceedes first threshold, determine that this service path exists looped network, can detect effectively rapidly the looped network existing in service path, and by relevant suspension processing, can effectively avoid the impact of looped network on business, improve the reliability of network.
In embodiments of the present invention, when first node generates after detection messages, can timing send this detection messages to the Section Point adjacent with this first node, particularly, for example one day 24h, only send once, or be fixed on moment t and send once, or regularly the moment of every day t1, t2 ..., tn send.
Alternatively, as an embodiment, in the method 100 shown in Fig. 2, this sends this detection messages to the Section Point adjacent with this first node in this service path, comprising:
Timing sends this detection messages to this Section Point.
Particularly, user can generate detection messages by pre-configured this first node, and configure this first node and send detection messages 9 of every mornings to Section Point, if really there is the looped network shown in Fig. 1 (b) in 9 service paths of a day, just can detect looped network, the line correlation of going forward side by side disconnects the operation of looped network, improves the reliabilty and availability of business network.
Consider that the appearance looped network in service path is not expected event, in order to detect in time the looped network event that may occur at any time, after all right configuration integrate detection messages of this first node, periodically send this detection messages to Section Point, for example each 1 hour, send once.Like this, once there is looped network in service path, this looped network can be detected effectively in time, by the operation of follow-up disconnection looped network, can effectively improve the real-time and the efficiency that detect looped network, thereby can improve the reliabilty and availability of business network.
Should be understood that in practical application, user can also configure this first node in the specific moment, sends this detection messages.For example user is by experience gained, service path every afternoon 2 possibilities that occur looped network higher, can configure first node and send one-time detection message 2 of every afternoons to Section Point.
Therefore, in embodiments of the present invention, by timed sending detection messages, once service path produces looped network, can be detected in time, and can break in time ring and process, thereby after can preventing that Ethernet service loopback from occurring, network maintenance staff can not detect in time, causes Ethernet service discontinuity events.
Should be understood that the example shown in Fig. 1 and the description of carrying out in conjunction with Fig. 1 are in order to help those skilled in the art to understand better the embodiment of the present invention above, and leave no choice but limit the scope of the embodiment of the present invention.Those skilled in the art, according to given Fig. 1 and corresponding description, obviously can carry out amendment or the variation of various equivalences, and such amendment or variation also fall in the scope of the embodiment of the present invention.
Should also be understood that the technical scheme that the embodiment of the present invention provides can be applied to arbitrary network product, transfer equipment or routing device.In addition, generate the technical scheme of topological diagram of looped network, also can be applied in the network architecture that equipment that any webmaster can manage forms,
Will also be understood that, in various embodiment of the present invention, the size of the sequence number of above-mentioned each process does not also mean that the priority of execution sequence, and the execution sequence of each process should determine with its function and internal logic, and should not form any restriction to the implementation process of the embodiment of the present invention.
Therefore, in embodiments of the present invention, whether the number of times of the detection messages forwarding according to service path receiving by judgement exceedes first threshold, can determine whether this service path exists looped network, looped network can effectively be detected, so that rapid damage looped network, can effectively improve the reliability of network.
Above, in conjunction with Fig. 1 and Fig. 2, describe the method detecting for business looped network according to the embodiment of the present invention in detail from the angle of node, below in conjunction with Fig. 3, describe the method detecting for business looped network according to the embodiment of the present invention from the angle of webmaster.
As shown in Figure 3, according to the method 200 detecting for business looped network of the embodiment of the present invention, for example, can be carried out by webmaster, the method 200 comprises:
S210, what reception first node sent is used to indicate the first message that has looped network through the service path of this first node;
S220, according to this first message, is identified for disconnecting the destination node of this looped network;
S230, sends the second message to this destination node, and this second message is used to indicate and disconnects this looped network.
Therefore, the method detecting for business looped network of the embodiment of the present invention, according to first message that has looped network through the service path of this first node that is used to indicate of first node transmission, be identified for disconnecting the destination node of looped network, and indicate this destination node to disconnect this looped network, effectively improve the reliability that network uses.
In S210, receive first message that has looped network through the service path of this first node that is used to indicate of first node transmission; Wherein, first node can be any node in this looped network, can also be the multiple nodes in this looped network, more specifically, can be looped network all nodes of process.
In S220, according to this first message, be identified for disconnecting the destination node of this looped network, particularly, can automatically determine this destination node according to automatically shutting down priority algorithm; Also can, by present the topological diagram of this looped network to user, determine this destination node according to user instruction, below will describe in detail.
Alternatively, as an embodiment, the destination node that this is identified for disconnecting this looped network, comprising:
According to this first message, determine this looped network, and generate the topological diagram of this looped network;
Present this topological diagram;
Receive the 3rd message that is used to indicate this destination node that user sends according to this topological diagram;
According to the 3rd message, determine this destination node.
Particularly, be illustrated in figure 4 example with service path, the first message that webmaster sends according to each node in looped network, determine that the step of topological diagram of this looped network is as follows:
1) the looped network event message that the port P8 of the port P7 of the port P5 of the port P4 of the port P3 of the port P2 of receiving node 2, node 2, node 2, node 3, node 3, node 4 and the port P6 of node 4 report;
2) can search for by optical fiber, can draw the topology of the port P3 of node 2 and the port P5 of node 3; The topology of the port P4 of node 2 and the port P6 of node 4; The topology of the port P8 of node 4 and the port P7 of node 3;
3) can search for by Ethernet service, draw the topology in node: the topology of node 2 inner port P2, P3 and P4; Port P5 in node 3 and the topology of P7; Port P8 in node 4 and the topology of P6.
According to above-mentioned steps, determine the topological diagram of the looped network shown in Fig. 4.
