Specific embodiment

The application provides a kind of demarcation method of network failure, and Fig. 1 is the schematic diagram for the network architecture that the application is applicable in, such as Shown in Fig. 1, which includes: exchange network, control equipment and server.Exchange network is made of multiple switch, should Exchange network can be CLOS network.The number of server be it is multiple, the service interaction between server is needed by the exchange Network.Control equipment is the equipment that the application increases newly, and control equipment can be with server and switch communication, wherein control is set It is standby to be led to by Simple Network Management Protocol (Simple network manage protocol, SNMP) between interchanger Letter.

Fig. 2 is a kind of structural schematic diagram of CLOS network, as shown in Fig. 2, the CLOS network is made of three-tier switch: connecing Enter layer, convergence layer and core layer, wherein the interchanger for being located at access layer (network lowermost layer) is known as access switch or boundary is handed over It changes planes, each edge switch can be connect with multiple servers, and server accesses network by edge switch.Convergence layer The interchanger of (network middle layer) is known as convergence switch, and the interchanger of core layer (network is top) is known as core switch, Each convergence switch is connect with multiple edge switch, and each core switch is connect with all convergence switches.

Fig. 3 is another structural schematic diagram of CLOS network, as shown in figure 3, the network only includes two layer switch: core Layer and access layer, each core switch are all connected with all edge switch.

In the application, each server sending and receiving in addition to finishing service message of network shown in Fig. 1 will also generate spy Text is observed and predicted, is detected two-by-two by probe messages and other servers in network, when detecting link and breaking down, to control Control equipment sends fault warning message, is broken down with notice control device network.And in the event for receiving control equipment transmission When barrier detection instruction message, generates tracking message and be sent to the interchanger of connection.

Control equipment is used to that message matching strategy, the message matching of each interchanger to be respectively configured for each interchanger in network Strategy is all the same, and the message matching strategy is for being matched and being counted to the tracking message that server is sent.When control equipment After the fault warning message for receiving server transmission, instruction server generates tracking message, subsequent to have sent in tracking message Cheng Hou, receives the number for the tracking message that each interchanger reports, and determines the interchanger to break down according to the number of tracking message.

Interchanger is used to that tracking message to be matched and be counted according to message matching strategy.

Based on above-mentioned Fig. 1-network architecture shown in Fig. 3, the demarcation method of network failure provided by the present application, it is intended to solve In the prior art in the demarcation method of network failure, the problem of the configuration amount of interchanger greatly, more than occupancy resource.

How the technical solution of the application and the technical solution of the application are solved with specifically embodiment below above-mentioned Technical problem is described in detail.These exemplary embodiments can be combined with each other below, for the same or similar general Thought or process may repeat no more in certain embodiments.Below in conjunction with attached drawing, embodiments herein is described.

Fig. 4 is the flow chart of the demarcation method for the network failure that the embodiment of the present application one provides, as shown in figure 4, this implementation Example provide method the following steps are included:

Step S101, control equipment sends fault detection instruction message, failure to the server for carrying out failure demarcation Detection instruction message is used to indicate server and tracks message to transmission using failure IP to be tracked.

After server receives fault detection instruction message, according to failure IP to be tracked to tracking message is generated, this is chased after The source IP address and purpose IP address of track message are failure IP to be tracked to the source IP address and purpose IP address for including.Tracking Message should be different from existing message (including existing service message and probe messages), can will track message in the application Source port, destination port, differential server code point (Differentiated Services Code Point, DSCP) or It is one or more using the particular value for being different from existing message in person's agreement, so that tracking message is different from existing message.DSCP It is the QoS in order to guarantee communication, 8 identification bytes on the head data packet IP are encoded, and segmentation service classification is carried out, and distinguish clothes The priority of business.

Optionally, before step S101, control equipment determines server and event to be tracked for carrying out failure demarcation IP pairs of barrier.Illustratively, control equipment can be determined as follows server for carrying out failure demarcation and wait track IP pairs of failure: control equipment receives the fault warning message of at least one server transmission, includes in the fault warning message Detect IP pairs of failure of server, control equipment determine use according to IP pairs of the failure received from least one server In carry out fault detection server and to be tracked IP pairs of failure.

Wherein, fault warning message is when server detects network failure to control equipment transmission, and failure is accused Alert message is for notifying control device network to break down.Include multiple servers in network, is visited two-by-two between server It surveys, to determine whether network breaks down, and break down IP pairs of failure, a failure IP is to including a source IP address With a target ip address, source IP address and purpose IP address of the failure IP to the message for indicating to occur packet loss.One server The failure IP reported is to may be one or more.

When only one server reporting fault alarm information, control equipment determines that the server is for carrying out failure The server of demarcation.When there is multiple server reporting fault alarm informations, control equipment can be selected from multiple servers Part server can also determine that Servers-all carries out failure demarcation for carrying out failure demarcation.What multiple servers reported It may be overlapped between IP pairs of failure, the failure in network may be caused by the same exchange fault, if Servers-all Failure demarcation is all carried out, server can generate a large amount of tracking message, occupy a large amount of Internet resources, and therefore, server can be with Selected section server is for carrying out failure demarcation, for example, selecting a server to delimit for failure from multiple servers.

For example, the failure IP that server A and server B report is to failure IP identical, that server A and server B report To may, if two servers all carry out failure demarcation, cause Internet resources as caused by identical failed switches Waste, control equipment can choose server A or server B for failure demarcation.

The failure IP that receives of control equipment to may also be it is multiple, control equipment from multiple failure IP centering determine to IP pairs of the failure of tracking, failure IP to be tracked may be one or more.When the server for carrying out failure demarcation is more When a, the failure IP to be tracked of multiple servers may be identical, it is also possible to different.

In the above method, control equipment is delimited by receiving the fault warning message that server reports, triggering failure, should Method is detected network failure automatically by server and is reported to control equipment, so as in time to network failure carry out delimit and It excludes, the network problem for helping operation maintenance personnel discovery complicated makes operation maintenance personnel as much as possible extensive before client finds the problem Multiple failure, to promote the whole competitiveness of network.

Optionally, before step S101, control equipment receives the failure that network management system is sent and delimits instruction message, optional , which, which delimits instruction message and can be gateway system and receive, sends after the failure of reporting of user.Control equipment according to The failure is delimited instruction message triggering failure and is delimited.Optionally, it can also include for carrying out which, which delimits in instruction message, The mark for the server that failure is delimited, if in failure demarcation instruction not including the mark for carrying out the server of failure demarcation Know, then controlling equipment may further be random from multiple servers or according to the one or more servers of preset rules selection For carrying out failure demarcation, failure IP to be tracked by control equipment to also being specified.

Optionally, control equipment can be delimited with periodic triggers failure, so as to find network failure in time.Work as control When control equipment detection cycle reaches, control equipment can it is random from multiple servers or according to preset rules select one or Multiple servers are for carrying out failure demarcation, and failure IP to be tracked by control equipment to also being specified, then, control equipment to Fault detection instruction message is sent in the server for carrying out failure demarcation.

Step S102, control equipment receives the number for the tracking message that each interchanger in network is sent, and tracks message Number is that interchanger is obtained according to message matching strategy matching, wherein message matching strategy is used to indicate interchanger to service The tracking message that device is sent is matched and is counted.

Wherein, the message matching strategy of the configuration on each interchanger is identical.It is pre- that message matching strategy can be control equipment It is first allocated to interchanger, is also possible to other equipment or administrative staff's manual configuration to interchanger.Illustratively, it controls Equipment can send configuration message to each interchanger by SNMP, include the message matching strategy, the configuration in the configuration message Message is used for configuration message matching strategy.

The method of the present embodiment, since the configuration message matching strategy of each interchanger is identical, and it only need to be every for controlling equipment A interchanger configures a message matching strategy, compared with the prior art in, reduce the configuration amount of interchanger.The prior art In, an interchanger has multilink, need each of the links configuration parameter for each interchanger, and different links Configuration parameter is different, and configuration amount is very big.And the method for the present embodiment is not influenced by networking, for example, when the IP address in network When changing, message matching strategy is had no effect on.

Optionally, message matching strategy is qos policy, which includes: an advanced accesses control list (traffic is made in (Access Control List, ACL), stream type (traffic classifier) and flowing Behavior), stream type is associated with flowing.Wherein, the match options of advanced ACL include at least one of following information: Track source port, destination port and the DSCP of message.

By taking port numbers as an example, the value of existing port number is 0-65535, and port numbers can be divided into following three categories:

(1) generally acknowledge port (Well Known Ports): from 0 to 1023, their tight bindings (binding) are in some clothes Business.The communication of these usual ports has clearly indicated that the agreement of certain service.Such as: port numbers 80 indicate hypertext transfer protocol (HyperText Transfer Protocol, HTTP) communication, port numbers 21 indicate File Transfer Protocol (File Transfer Protocol, FTP) communication.

(2) registered port (Registered Ports): from 1024 to 49151.They are loosely bound to some services, That is there are many service bindings in these ports, these ports are equally used for many other purposes.Such as: at many systems Dynamic port is managed since 1024 or so.

(3) dynamic and/or privately owned port (Dynamic and/or Private Ports): from 49152 to 65535.

In the present embodiment, the source port number and destination slogan for tracking message can be third generic port 49152 to 65535 In any one port numbers, as long as the port numbers of tracking message are different from the port numbers of other messages.DSCP occupies 8 altogether A bit (bit), wherein first six digits are the value of DSCP, and rear two reservations, then the worth range of DSCP is 0~63, can be with Use some reserved values in 0-63 that can also newly define the DSCP of one 7 or 8 as the DSCP of tracking message.

Optionally, the match options of advanced ACL further include tracking the agreement of message, and the agreement for tracking message can be user Datagram protocol (User Datagram Protocol, UDP).

In the present embodiment, stream type is to flow the tracking arrived as statistical match to the message matching advanced ACL received The number of message.When configuring to qos policy, advanced ACL can be first configured, stream type and flowing work is being defined, is then configuring Stream type is associated with by qos policy with flowing.

Optionally, which is global type, and global type needs not distinguish between interface, i.e., interchanger is to all The message received on interface all carries out unified matching and counting using the message matching strategy.Optionally, the message matching plan Slightly local type, local type need distinguishing interface, i.e. interchanger matches the message being matched on each interface respectively And counting, correspondingly, the message number that subsequent switch reports each Interface Matching to arrive to server, server is according on interchanger Each Interface Matching of report to message number can position that failure has occurred in which interface of interchanger.

Step S103, the number for the tracking message that control equipment is sent according to each interchanger, determines the exchange broken down Machine.

The number for the tracking message that server is sent is fixed value, if tracking message there is no network failure The number for the tracking report that each interchanger receives on the path of process is also the fixed value, in case of network failure, is occurred The number of the exchange opportunity packet loss of failure, the tracking message for causing subsequent switch to receive is reduced.Control equipment receives respectively After the number for the tracking message that interchanger is sent, the interchanger on the path of tracking message process is first determined, specifically, control is set It is standby to judge whether the number of the tracking message received on each interchanger is greater than 0, if the tracking message that interchanger receives Number is greater than 0, illustrates that the interchanger is the interchanger tracked on the path that message passes through, if the tracking report that interchanger receives The number of text is 0, then illustrating the interchanger not is the interchanger tracked on the path that message passes through.

Determine tracking message by path on interchanger after, according to the networking situation of interchanger, can determine and chase after Then the sequence of interchanger on the path that track message passes through compares tracking message by the number of the interchanger on path, if Since some interchanger, the tracking message that interchanger receives on path is all reduced, then can be determined before the interchanger Failure has occurred in the link of one interchanger to the interchanger, causes to track message loss, so as to cause friendship subsequent on path The tracking message number received of changing planes all is reduced.

Fig. 5 is a kind of forwarding schematic diagram for tracking message, as shown in figure 5, the CLOS network includes two layer switch: boundary Interchanger and core switch, the number of edge switch are 4, and the number of core switch is 2, and server number is 2, Server 1 is connect with edge switch 1 and 2, and server 2 and edge switch 3 and 4 connect, edge switch 1,2,3,4 with Core switch 1 and core switch 2 connect.It is assumed that the IP address of server 1 is IP1, the IP address of edge switch 1 is IP2, the IP address of edge switch 2 are IP3, and the IP address of edge switch 3 is IP4, and the IP address of edge switch 4 is IP5, the IP address of core switch 1 are IP6, and the IP address of core switch 2 is IP7, and the IP address of server 2 is IP10.

Server 1 is the server for carrying out failure demarcation, it is assumed that server 1 has sent 100 tracking messages, tracking Message forwarding path is the path that thick solid black lines are passed through in Fig. 5, and thin solid black lines indicate that the link between equipment, dotted line indicate Link failure, then track message process path are as follows: server 1, edge switch 2, core switch 2, edge switch 3, Server 2.Wherein, server 1 has sent 100 tracking messages to edge switch 2, and edge switch 2 receives 100 and chases after Track message, core switch 2, edge switch 3, server 2 receive 80 tracking messages, illustrate that edge switch 2 arrives Failure has occurred in the link of core switch 2, so as to cause tracking message loss.

The method of the present embodiment, control equipment send fault detection instruction to the server for carrying out failure demarcation and disappear Breath, the failure indication information are used to indicate server and are received using failure IP to be tracked to tracking message, control equipment is sent The number for the tracking message that each interchanger in network is sent, the number for tracking message is that interchanger is obtained according to message matching strategy It arrives, message matching strategy is for being matched and being counted to the tracking message that server is sent, wherein the report on each interchanger Literary matching strategy is identical, and the number for the tracking message that control equipment is sent according to each interchanger determines the interchanger to break down. Since the message matching strategy on each interchanger is identical, and the message matching strategy of interchanger is not influenced by networking, to make The configuration amount for obtaining interchanger greatly reduces, and this method carries out failure demarcation according to the number of tracking message, realizes simple, demarcation Quick and precisely.

On the basis of example 1, optionally, control equipment receives the tracking message that each interchanger in network is sent Number before, control equipment sends enabled instruction message to each interchanger, which, which is used to indicate interchanger, makes It can message matching strategy.In this method, the message matching strategy on interchanger is in non-enabled state, interchanger under normal circumstances It will not be matched and be counted according to the message matching strategy after receiving message, only receive the enabled of control equipment transmission After instruction message, message matching and counting just will do it after policy enabled to the message matching.

After failure is delimited, interchanger can enable to the message matching strategy automatically.Illustratively, it hands over Change planes to control equipment report tracking message number for a period of time after, automatically the message matching strategy enable. Alternatively, interchanger starts timing after receiving enabled instruction message, when reaching preset time, such as enabled instruction is received After message 30 minutes, automatically the message matching strategy enable.

Optionally, control equipment can also go to enable after determining the interchanger to break down to the transmission of each interchanger Instruction message, this goes enabled instruction message to be used to indicate interchanger to go to enable to message matching strategy.

By being enabled when failure is delimited and started to message matching strategy, after failure is delimited, to message Enable with strategy, interchanger is avoided, there is no also matching to the message received when failure, to occupy in network The resource of interchanger.

Certainly, in the possible implementation of the application, the message matching strategy on interchanger, which can also be constantly in, to be made Energy state, the application limit not to this.

Fig. 6 is the flow chart of the demarcation method for the network failure that the embodiment of the present application two provides, and embodiment one is set from control Standby angle describes the demarcation method of network failure, and the present embodiment is described from the angle of server, as shown in fig. 6, the present embodiment The method of offer the following steps are included:

Step S201, server other servers into network send probe messages.
