Here it should be noted that, in same business chain, the sequence number of the probe data packet of comprehensive sounding chain connectedness is different in the same time; And for different business chain, the sequence number of probe data packet is likely identical.Illustrating, is 1,2,3,4,5 for not detecting the sequence number of the probe data packet of the connectedness of the first business chain in the same time; The sequence number not detecting the probe data packet of the connectedness of the second business chain is in the same time 1,2,3,4.Therefore, two parameter unique identifications probe data packet must be identified by sequence number and business chain.
Described grader generates detection data and is surrounded by multiple implementation method, provides wherein two kinds of possible implementations here:
The first possible implementation:
Obtain the packet of new definition agreement, add probe data packet mark in the packet header of the packet of described new definition agreement and generate probe data packet.
Probe data packet is the protocol data bag that technical staff newly defines as required, adds the probe data packet mark of definition, be used for identifying described probe data packet in the packet header of probe data packet.
The implementation that the second is possible:
Obtain the packet that there is agreement, add probe data packet mark at the described reserved field that there is the packet header of the packet of agreement and generate probe data packet.
Choose the packet of a protocols having, in the reserved field in the packet header of this packet, add the mark of probe data packet as probe data packet.
Grader, when generating probe data packet, can generate according to the control of business cooperation layer the probe data packet that comprehensive sounding works in coordination with the business chain specified by layer.When user needs to detect certain business chain connective, indicating services is worked in coordination with layer and is sent probe data packet to grader and generate instruction, and described probe data packet generates the business chain mark that the business chain that will detect to some extent is carried in instruction.Grader receives the probe data packet generation instruction that business cooperation layer sends, and generates the probe data packet of this business chain of detection.
Grader, when generating probe data packet, can generate according to the time interval pre-set the probe data packet detecting certain business chain automatically.Illustrate: grader pre-sets the connectedness detecting certain business chain week about, then grader generates the probe data packet of this business chain of detection week about automatically.Here it should be noted that, the time interval pre-set can sets itself according to actual needs, arrange the identical time interval can to every bar business chain, also can arrange the different time intervals.
In the particular embodiment, the described network equipment is switch or service node, and the described network equipment obtains probe data packet and comprises:
The described network equipment receives the packet that in business chain, a network equipment sends;
The described network equipment detects described packet and whether carries probe data packet mark;
When described packet carry probe data packet mark time, the described network equipment using received packet as described probe data packet.
Switch is business data flow forwarding unit in the business chain in business chain, and service node is the value-added service treatment facility of business data flow in business chain.When the network equipment be switch in business chain or service node time,
The probe data packet that switch or service node obtain is that a upper network equipment of business chain belonging to described probe data packet sends.When comprehensive sounding chain connective, grader generates probe data packet, and probe data packet is imported the business chain belonging to described probe data packet, and probe data packet is forwarded to each network equipment in business chain successively.
Switch and service node, when receiving the packet that a network equipment sends, detect described packet and whether carry probe data packet mark, when described packet carries probe data packet mark, show that received packet is probe data packet.Business chain mark entrained by received probe data packet, is forwarded to the next network equipment of the business chain belonging to described business chain mark by this probe data packet.In SDN, the switch be connected with grader receives the probe data packet that grader sends, service node receives the probe data packet that the switch that is connected with this service node sends, and the switch be not connected with grader receives the probe data packet that in the business chain detected, a upper switch sends.
Illustrate, suppose the stream list item according to controller configuration, the network equipment that packet flows through successively in business chain A is: grader-switch A 1-service node A2-switch A 1-service node A3-switch A 1-switch A 4-service node A5-switch A 4.If the connectedness of comprehensive sounding chain A, then generate probe data packet by grader, add probe data packet mark in the packet header of probe data packet, in probe data packet, add the business chain mark of business chain A and the sequence number of this probe data packet.Probe data packet is sent to switch A 1 by grader, the business chain mark that switch A 1 carries according to affiliated probe data packet, probe data packet is forwarded to service node A2, described probe data packet is sent to switch A 1 by service node A2 again, described probe data packet is forwarded to service node A3 by switch A 1, described probe data packet is sent to switch A 1 by service node A3 again, described probe data packet is forwarded to switch A 4 by switch A 1 again, described probe data packet is forwarded to service node A5 by switch A 4 again, described probe data packet is sent to switch A 4 by service node A5.Then probe data packet will flow through successively: grader-exchange A1-service node A2-switch A 1-service node A3-switch A 1-switch A 4-service node A5-switch A 4.The connectedness of comprehensive sounding chain A, any one network equipment in business chain A or communicate to connect fault between any two network equipments, the transmission in business chain A of probe data packet all can be interrupted.
It will be appreciated by persons skilled in the art that the stream list item of the business chain configuration service chain that controller issues according to business cooperation layer, and stream list item is handed down to switch.After switch receives packet, the business chain mark entrained by this packet identifies the business chain belonging to this packet, according to the stream list item of controller, and the packet received by forwarding.Switch also can business chain mark entrained by probe data packet, the probe data packet received by forwarding, realizes the transmission in business chain belonging to business chain mark that detection data wraps in entrained by it.
In above-mentioned example, in grader, there is the function generating and send probe data packet, in switch and service node, have the function detecting and send probe data packet.
Step 202: the described network equipment generates detection event message according to described probe data packet.
Step 203: described detection event message is reported to monitoring server by the described network equipment, described detection event message is used for reporting the described network equipment to obtain the event of described probe data packet to described monitoring server.

After the network equipment obtains probe data packet, generate and report the detection event message obtaining described probe data packet event.In detection event message, the information of carrying comprises: the business chain mark, network device identity and the network equipment that carry in the sequence number of the probe data packet that the network equipment obtains, probe data packet receive the time of reception of probe data packet.Wherein, the sequence number of probe data packet and business chain mark unique identification probe data packet.Network device identity reports the network equipment of this probe data packet event for identifying.The time of reception, each network equipment on the transmission path of differentiated service chain received the sequencing of described probe data packet.
When a detection business chain connective, after a network equipment in business chain gets probe data packet, generate detection event message, report the event receiving probe data packet to monitoring server, show that this network equipment normally works.If network equipment failure causes the failure of connectivity of described business chain, then this network equipment can not report detection event message to monitoring server, and, the network equipment of this fault can not continue to forward detection data message, cause the Transmission of detection data message in business chain, other network equipments in the business chain that probe data packet does not flow through can not receive this probe data packet, can not report detection event message to monitoring server.If the link failure between two network equipments causes the failure of connectivity of described business chain, the network equipment that then probe data packet first flows through can report detection event message to monitor server, due to link failure, another network equipment that then probe data packet will flow through cannot receive probe data packet, also just detection event message cannot be reported to monitor server, other network equipments of the business chain that probe data packet does not flow through also cannot receive this probe data packet, can not report detection event message to monitoring server.。
When a detection business chain connective, if the connectedness of this business chain is good.Probe data packet then can flow through each network equipment in this business chain according to the transmission path of packet successively.On the transmission path of then this business chain, each network equipment can obtain probe data packet, and reports detection event message to monitoring server.
After the network equipment acquisition probe data packet of normal work, according to the business chain mark of carrying in probe data packet, also obtained probe data packet to be forwarded the next network equipment of the business chain so far belonging to business chain mark.
The connective detection method flow chart of business chain that Fig. 3 provides for another embodiment of the present invention, comprising:
Step 301: monitoring server receives the detection event message that multiple network equipment sends respectively, described detection event message is used for the event that report network equipment obtains probe data packet.
Step 302: described monitoring server obtains the stream list item of the business chain preset.
Step 303: described monitoring server is according to the abort situation of received detection event message and described stream list item comprehensive sounding chain.
In the process that the connectedness of business chain detects, monitor server receives the detection event message that multiple network equipment reports.Described detection event message is the network equipment after acquisition probe data packet, generates according to described probe data packet, for obtaining the event of probe data packet to monitor server report network equipment.Similar with the embodiment shown in Fig. 2 herein, with reference to the description of the embodiment shown in figure 2, repeat no more here.
In actual applications, monitor server can be the independent server apparatus disposed in SDN, also can be as monitor server using the business cooperation layer of SDN, dispose the function of monitor server, using the controller of SDN as monitor server, the function of monitor server can also be disposed in the controller.
Described monitoring server is the controller of SDN, and the stream list item that described monitoring server obtains the business chain preset comprises:
Described controller receives the business chain that business cooperation layer sends;
Described controller is according to the stream list item of described business chain configuration service chain;
Described controller obtains the stream list item of the business chain configured.
Controller in SDN can receive the business chain that business cooperation layer sends, the stream list item of configuration service chain, obtains the stream list item of the business chain that controller self configures.
When during monitor server is business cooperation layer in SDN or SDN independent dispose server time, the stream list item that described monitoring server obtains the business chain preset comprises:
Described monitoring server receives the stream list item controlling the business chain sent from software defined network SDN;
In SDN, generated the stream list item of business chain by controller, when monitor server is the server of business cooperation layer or independent deployment, receive the business chain stream list item that controller sends.
Monitor controller is added up the detection event message that received multiple network equipments send, the connectedness of comprehensive sounding chain, particularly when business chain fault, and the abort situation of comprehensive sounding chain.
The described abort situation detecting described business chain according to described detection event message and described stream list item has a lot of implementation, is specifically described below for wherein a kind of possible implementation.
Described monitoring server comprises according to the abort situation of received described detection event message and described stream list item comprehensive sounding chain:
Multiple detection event messages that described monitoring server statistics generates according to same probe data packet detect event group as one, and the sequence number of the probe data packet entrained by each detection event message in described detection event group and business chain identify identical;
Described monitoring server sorted to the detection event message in described detection event group according to the time of reception entrained by each detection event message, and the described time of reception is the time of reception reporting the network equipment of described detection event message to receive probe data packet;
Described monitoring server utilizes the detection forward-path sequence of the detection event message in described detection event group being obtained to described probe data packet;
Described monitoring server search described detection forward-path and described business chain identify belonging to the difference of stream list item of business chain locate abort situation in this business chain.
Multiple detection event messages that the network equipment received by monitoring server reports relate to the connectedness detection of many business chain.The sequence number that first must detect probe data packet entrained by event message according to received and business chain mark are added up, and sequence number and all identical detection event message of business chain mark are divided into a detection event group.Illustrated in the embodiment shown in Figure 2, sequence number and business chain identify two parameters and uniquely determine a probe data packet, and namely entrained sequence number generates according to same probe data packet with all identical detection event message of business chain mark.Therefore, multiple detection event messages in detection event group are that the network equipments different in business chain is not obtaining the generation of same detection data message in the same time, namely detect in the process of the connectedness of same business chain, the detection event message that the heterogeneous networks equipment of business chain reports.
Then, the detection event message in same detection event group was sorted according to the entrained time of reception, before the time of reception, detection event message early came, after the detection event message in the evening time of reception comes.The time of reception detected entrained by event message is the moment that the network equipment obtains probe data packet.In the connective process of comprehensive sounding chain, most of network equipment generates detection event message according to received probe data packet, and the time of reception in the detection event message generated is exactly the moment that the network equipment receives probe data packet.

Utilize the probe transmission path sequence of the detection event message in described detection event group being obtained to probe data packet.Obtain device identification entrained in each detection event message, the sequence of the detection event message in detection event group is utilized to sort to device identification, obtain detection data when wrapping in comprehensive sounding chain connective, forward-path in the network device, i.e. the probe transmission path of probe data packet.
Detected business chain can be learnt according to the business chain mark that the detection event message in detection event group carries.The business chain stream list item of the probe transmission path of probe data packet with the business chain detected is compared.Business chain stream list item and the transmission path of data flow in this business chain.Search described probe transmission path and described business chain identify belonging to the difference of stream list item of business chain locate abort situation in this business chain.
Find described probe transmission path and described business chain identify belonging to the difference of stream list item of business chain time, search the next network equipment of the end Network equipment in described probe transmission path according to business chain stream list item.Fault location is next network equipment failure, or the link failure between the end Network equipment in described probe transmission path and the next network equipment.
Certainly, described method also comprises:
The stream list item of the business chain belonging to described probe transmission path identifies with described business chain is identical, then the connectedness of detected business chain is good.
Illustrate: the connectedness of comprehensive sounding chain A, the network equipment that the packet described by business chain stream list item of business chain A flows through successively is: grader-switch A 1-service node A2-switch A 1-service node A3-switch A 1-switch A 4-service node A5-switch A 4.Monitor server statistical series are number identical, and entrained business chain mark is all the detection event group of the detection event message composition comprehensive sounding chain A of the mark of business chain A.All detection event messages in detection event group were sorted according to the time of reception, utilizes the probe transmission path sequence of the detection event message in described detection event group being obtained to probe data packet.
