In a kind of implementation of the application, in order to improve the data message forwarding ability of load-balancing device cluster, and Extend the data message transmitting capacity of centralized session synchronization equipment, the quantity of centralized session synchronization equipment can be it is multiple, Correspondingly, the Internet protocol of each centralized session synchronization equipment can be configured in every load-balancing device Address (Internet Protocol, IP), in order to bear in a centralized session synchronization device upgrade or failure Carrying equalizing equipment can choose other centralized session synchronization equipment to send datagram or to its simultaneous session.

In the embodiment of the present invention, interchanger can be replaced by router.

In the embodiment of the present invention, load-balancing device can be four-layer load-equalizing equipment or seven layers of load-balancing device. Wherein, the work of four-layer load-equalizing equipment is in open system interconnection (Open System Interconnection, OSI) mould The 4th layer (transport layer) of type is forwarded data message by the destination address and port of analyzing data message.Seven layers negative Equalizing equipment work is carried in the layer 7 (application layer) of osi model, destination address and port in addition to analysis data message are also divided The application layer messages such as the uniform resource locator (Uniform Resource Locator, URL) of data message are analysed to datagram Text is forwarded.

In the embodiment of the present invention, load-balancing device locally be can store: be established between client and application server cluster Session.

In the embodiment of the present invention, centralized session synchronization equipment locally be can store: from each in above-mentioned system for cloud computing The session of a load-balancing device synchronization gain.

In the embodiment of the present invention, centralized session synchronization equipment may include multiple CPU cores, can choose wherein any one A CPU core is as host CPU core；Centralized session synchronization equipment can also include memory.

In the embodiment of the present invention, needing proof load equalizing equipment to centralized session synchronization equipment is that routing is reachable.

Below by specific embodiment, the present invention is described in detail.

Fig. 1 a is the first flow diagram of file transmitting method provided in an embodiment of the present invention, and this method is applied to cloud Calculate the load-balancing device in network, comprising the following steps:

S101, the target data message that desampler is sent.

In system for cloud computing, when client is needed to application server pocket transmission target data message, first by mesh Mark data message is sent to interchanger, carries out route assignment to target data message by interchanger, i.e., is determined and be used for by interchanger The load-balancing device of target data message is forwarded, then target data message is sent to identified load balancing by interchanger Equipment, the target data message of identified load-balancing device desampler transmission are simultaneously forwarded to application server cluster.Its In, it may include multiple application servers that application server cluster, which is used to client and provides the server zone of application service,.

It is understood that identified load-balancing device is certain in multiple load-balancing devices in system for cloud computing One load-balancing device.

It, can be according to preset equivalent route-Hash after interchanger receives target data message in the present embodiment (Equal-CostMultipathRouting hash, ECMP-hash) algorithm carries out route assignment to target data message, i.e., It can be determined in multiple load-balancing devices in system for cloud computing for forwarding target according to preset ECMP-hash algorithm The load-balancing device of data message.Certainly, the application is only illustrated for above-mentioned, and interchanger is to target data message The method for carrying out route assignment is not limited to this.

S102 searches number of targets in the session being locally stored for having received the load-balancing device of target data message According to the corresponding session of message.

In the present embodiment, load-balancing device is generally transmission control protocol (Transmission in the agreement of transport layer Control Protocol, TCP), thus be to forward statefully when load-balancing device forwarding target data message, that is, it loads Equalizing equipment is to be forwarded based on session corresponding to target data message to target data message.

It is understood that being received if interchanger receives the target data message of client transmission in interchanger Before the target data message sent to client, built by three-way handshake signal between client and application server cluster The corresponding session of target data message is stood.

Specifically, above-mentioned load-balancing device forwarded produced when establishing the session for the session established Three-way handshake signal in synchronization (synchronous, SYN) packet, then load-balancing device can establish session complete when It carves, the session of above-mentioned foundation is locally stored in load-balancing device, be then based on stored session and turn to application server cluster Send out target data message.For example, load-balancing device can load-balancing device be locally stored above-mentioned foundation session five Tuple information.Wherein, the five-tuple information of session are as follows: the source IP address of session, source port, purpose IP address, destination port with And transport layer protocol type.It will be appreciated by persons skilled in the art that a target data message corresponds to a unique meeting Words.

In the present embodiment, target data message may include the five-tuple information of its corresponding session.Thus, load balancing After equipment receives the target data message of interchanger transmission, the five-tuple information that target data message is included can be read, According to the five-tuple information, in the session that load-balancing device is locally stored, five-tuple information and target data message are searched The identical session of five-tuple information for being included.Certainly, the application is only illustrated for above-mentioned, and load-balancing device exists The method that the corresponding session of target data message is searched in the session that load-balancing device is locally stored is not limited to this.

S103, if do not searched in the session being locally stored for having received the load-balancing device of target data message To the corresponding session of target data message, target data message is sent to interchanger, so that interchanger is by target data message It is sent to centralized session synchronization equipment, so that sheet of the centralized session synchronization equipment according to centralized session synchronization equipment The session of ground storage, is sent to application server cluster for target data message.

In practical application, multiple load-balancing devices in system for cloud computing constitute load-balancing device cluster, at this In cluster, one load-balancing device of each node on behalf, when the interstitial content of load-balancing device cluster changes, For example some or certain several nodes break downs or number of nodes increase, accordingly, interchanger detects the quantity of next-hop It decreases or increases, then exchange opportunity is according to preset ECMP-hash algorithm or by other methods to the data message received Route assignment is re-started, the path of most of data message is caused to change.

Further, data message is sent to by interchanger route assignment is re-started to it after identified load balancing After equipment, identified load-balancing device very likely searches meeting corresponding less than data message in the session being locally stored Words, so as to cause to data message retransmission failure.

For example, as shown in Figure 1 b, it is assumed that have 4 load-balancing devices that can be worked normally, mesh in system for cloud computing Mark data message 1 to the corresponding session of target data message 4 is respectively session 1 to session 4, and load-balancing device 1 is equal to load Weighing apparatus equipment 4 is stored with session 1 to session 4 respectively.After interchanger is sequentially received target data message 1 to target data message 4, Route assignment is carried out to target data message 1 to target data message 4 according to preset ECMP-hash algorithm, route assignment As a result are as follows: forward target data message 1 to target data message 4 respectively by load-balancing device 1 to load-balancing device 4.

As illustrated in figure 1 c, it if the interstitial content of load-balancing device cluster changes, is set with some load balancing For standby delay machine, such as 1 delay machine of load-balancing device, at this point, interchanger detects that the quantity of next-hop reduces 1, then interchanger root Route assignment is re-started to the target data message 1 received to target data message 4 according to preset ECMP-hash algorithm, Assuming that the result of route assignment are as follows: target data message 1 to 3 is forwarded by load-balancing device 2 to load-balancing device 4 respectively, Target data message 4 is forwarded by load-balancing device 2.Then load-balancing device 2 to load-balancing device 4 cannot be respective The corresponding session of target data message to be forwarded is found in the session being locally stored, so as to cause to target data message Retransmission failure.

When load-balancing device does not find target data message pair in the session of load-balancing device being locally stored When the session answered, and since interchanger does not store target data message, load-balancing device can be sent out target data message It send to interchanger, so that the target data message received is sent to centralized session synchronization equipment by interchanger.

Specifically, in order to mark different marks in the different levels of osi model to target data message, load balancing is set It is standby to be packaged target data message, and the target data message after encapsulation is sent to interchanger, so that interchanger Target data message after the encapsulation received is sent to centralized session synchronization equipment.

For example, target data message can be encapsulated as virtual expansible local area network (Virtual by load-balancing device Extensible Local Area Network, vxlan) format.Interchanger receives the packed of load-balancing device transmission After the target data message of vxlan format, decapsulation or dissection process are not carried out to the target data message after the encapsulation, But the target data message for being encapsulated as vxlan format is directly sent to centralized session synchronization equipment.Certainly, the application It is only illustrated for above-mentioned, load-balancing device is not limited to this packaging method of target data message.

In the present embodiment, the session of centralized session synchronization equipment being locally stored are as follows: from each in system for cloud computing The session of load-balancing device synchronization gain.It should be noted that can be realized using the prior art from each of system for cloud computing A load-balancing device is to centralized session synchronization equipment simultaneous session.

As a preferred embodiment of the present invention, centralized session synchronization equipment is according to centralized session synchronization equipment Target data message is sent to application server cluster by the session being locally stored, and may include step S103a-S103c:

S103a, the host CPU core of centralized session synchronization equipment, from the meeting of centralized session synchronization equipment being locally stored In words, corresponding first session of target data message is determined.

Specifically, if centralized session synchronization equipment receives the target data message after the encapsulation that interchanger is sent, Firstly, host CPU core can carry out decapsulation processing to the target data message after the encapsulation, then, host CPU core can read mesh The five-tuple information for the corresponding session that mark data message is included is set according to the five-tuple information in centralized session synchronization The meeting identical with the five-tuple information that target data message is included of five-tuple information is determined in the standby session being locally stored Words.

S103b, the host CPU core of centralized session synchronization equipment is according to preset hash algorithm, to the attribute of the first session Carry out Hash calculation, according to calculated result, the selection target CPU core from the CPU core of centralized session synchronization equipment.

The host CPU core of centralized session synchronization equipment is determined from the session of centralized session synchronization equipment being locally stored After corresponding first session of target data message, host CPU core can be carried out according to attribute of the symmetrical hash algorithm to the first session Hash calculation obtains the Hash characteristic value of the first session；According to the Hash characteristic value of the first session, advised according to preset selection Then, to select the first session from other CPU cores in centralized session synchronization equipment local other than host CPU core corresponding Target CPU core.

It should be noted that target CPU core is other other than host CPU core in centralized session synchronization equipment local Some CPU core in CPU core.The corresponding unique target CPU core of first dialogue.Preset selection rule can be according to reality Border needs to preset, and can also rule of thumb set, the present invention is not intended to limit this.

S103c, the target CPU core of the host CPU core scheduling steps S103b of centralized session synchronization equipment, so that step The target CPU core of S103b is sent to application server cluster according to the first session, by target data message.

The host CPU core of centralized session synchronization equipment is determining corresponding first session of target data message, and selects Out after the corresponding target CPU core of the first session, the target CPU core can be dispatched and sent target data message according to the first session To application server cluster.

In this preferred embodiment, the host CPU core of centralized session synchronization equipment first determines that target data message is corresponding First session, reselection goes out the corresponding target CPU core of the first session, and the first session corresponds to a unique target CPU core.This Sample can be realized: as long as soon as the corresponding session of data message is the first session, it will by the corresponding target CPU core of the first session This data message is sent to application server cluster, that is to say, that and corresponding session is the different data message of same session, Application server cluster is sent to by the same CPU core, to realize to data message without lockization processing, improves concentration The session management ability of formula session synchronization equipment and the transmitting efficiency of number message.

It,, can be by the mesh of step S103b after step S103c in a kind of implementation based on above preferred embodiment Mark CPU core is sent completely the moment for what the overtime initial time of the first session was updated to target data message.

When it is possible to further be originated by the target CPU core of step S103b according to the time-out of updated first session It carves, whether the session timeout duration of the first session of detection reaches preset duration, if the session timeout duration of the first session reaches pre- If duration, the first session is destroyed.

Specifically, to save the free memory of centralized session synchronization equipment, and improve centralized session synchronization and set The standby managerial ability to the session for being synchronized to centralized session synchronization equipment local, target CPU core can periodically detect the The session timeout duration of one session, the overtime initial time of when time-out of the first session a length of first session to current time when It is long.If the session timeout duration of the first session reaches preset duration, then it is assumed that the corresponding TCP connection of the first session has disconnected, Target CPU core can destroy the first session.

In file transmitting method provided in an embodiment of the present invention, load-balancing device receives the target data that exchange is sent After message, the corresponding session of target data message is locally searched in load-balancing device, if searched less than by target data Message is sent to interchanger, target data message is sent to centralized session synchronization equipment by interchanger, by centralized session Target data message is sent to application server cluster by synchronizer.As it can be seen that load is equal in scheme provided in an embodiment of the present invention When the corresponding session of target data message is locally not present in weighing apparatus equipment, target data message is realized by centralized session synchronization equipment Transmission, avoid the load-balancing device in system for cloud computing be required to all load-balancing devices in storage cluster session letter Cpu resource caused by ceasing occupies excessive situation, to improve the ability of separate unit load-balancing device session management and entirely collect The ability of group's forwarding customer flow.

Fig. 2 is second of flow diagram of file transmitting method provided in an embodiment of the present invention, and this method is applied to cloud Calculate the load-balancing device in network, comprising the following steps:

S201, the target data message that desampler is sent.

S202 searches number of targets in the session being locally stored for having received the load-balancing device of target data message According to the corresponding session of message.

S203, if do not searched in the session being locally stored for having received the load-balancing device of target data message To the corresponding session of target data message, target data message is sent to interchanger, so that interchanger is by target data message It is sent to centralized session synchronization equipment, so that sheet of the centralized session synchronization equipment according to centralized session synchronization equipment The session of ground storage, is sent to application server cluster for target data message.

In the present embodiment, above-mentioned steps S201-S203 can be complete with the step S101-S103 of embodiment described in Fig. 1 respectively It is exactly the same, it is not repeated herein.

S204 sends control message to centralized session synchronization equipment by interchanger, so that centralized session synchronization Equipment carries out synchronizing information according to control message.

In the present embodiment, control message is the message for carrying out synchronizing information.Specifically, control message can be and include One session, and make centralized session synchronization equipment according to the message of session progress synchronizing information.Controlling message can also be with It is a state comprising a session, and makes centralized session synchronization equipment according to the report of state progress synchronizing information Text.

As a preferred embodiment of the present invention, control report is sent to centralized session synchronization equipment by interchanger Text may comprise steps of S204a and S204b:

S204a determines that the session for meeting preset synchronous condition in session that load-balancing device is locally stored is to same Walk session.

As described in step S202, session can establish between client and application server, then load-balancing device can be with The session of above-mentioned foundation is locally stored in load-balancing device.For example, load-balancing device can be in load-balancing device local Store the five-tuple information of the session of above-mentioned foundation.It is understood that according to the needs of client, client and application service Multiple sessions can be established between device group at different times, and then each load-balancing device also can store multiple built Vertical session.

It will be appreciated by persons skilled in the art that in the session of load-balancing device being locally stored, the duration The less session of data message number that is shorter and being forwarded can be classified as short connection session.Wherein, the duration of session Refer to that the data message number that session is forwarded refers to be continued in session from the duration for establishing session completion moment to current time In time, from storing the load-balancing device of the session based on the session to the data message number of application server pocket transmission.? In actual use, concentration is synchronized to by each load balancing in system for cloud computing to mitigate centralized session synchronization equipment processing The pressure of the session of formula session synchronization equipment local, each load-balancing device can need not be by the short companies of load-balancing device local Session synchronization is connect to centralized session synchronization equipment.Therefore, synchronous condition can be preset, is existed by each load-balancing device The session for meeting preset synchronous condition is determined in the session that load-balancing device is locally stored, then meets preset synchronization bar The session of part is the session that each load-balancing device needs to be synchronized to centralized session synchronization equipment.

In a kind of implementation, preset synchronous condition may include first presetting sub- synchronous condition and the second default son is same Step condition.Wherein,

First presets sub- synchronous condition can be with are as follows: the duration of session is greater than or equal to session persistence preset value.

Second presets sub- synchronous condition can be with are as follows: the data message number forwarded by session is than or equal to data message Forwarding number preset value.

Above-mentioned session persistence preset value and data message forwarding number preset value can be set according to actual needs, It can rule of thumb set, the present invention is not intended to limit this.

As an example it is assumed that the session persistence preset value set is 2s, the data message forwarding number preset value of setting It is 10.If the duration of session 1 is 5s, and the data message number that session 1 forwards is 20, then session 1 is on meeting State the session of preset synchronous condition.If the duration of session 2 is 5s, and the data message number that session 2 forwards is 8, Then session 2 is to be unsatisfactory for the session of above-mentioned preset synchronous condition.

Certainly, the application is only illustrated for above-mentioned, and preset synchronous condition is not limited to this.

It is understood that load-balancing device is possible to one client of storage and application server cluster at any time Between the session established.Therefore, load-balancing device can be according to the preset scan period successively to the sheet of load-balancing device The session of ground storage is scanned, to periodically determine that load-balancing device locally meets the session of preset synchronous condition For session to be synchronized.In a kind of specific embodiment, load-balancing device can be set load balancing in first scan The standby whole sessions being locally stored successively are scanned, and in non-first scan, local to load-balancing device not true It is set to and meets the session of preset synchronous condition and be successively scanned.Certainly, the application is only illustrated for above-mentioned, is born It carries equalizing equipment and determines the method for the session for meeting preset synchronous condition in the session being locally stored of load-balancing device simultaneously It is without being limited thereto.

S204b sends the control message comprising session to be synchronized to centralized session synchronization equipment by interchanger.

Load-balancing device meets preset synchronous condition in determining session that load-balancing device is locally stored After session to be synchronized, the control message comprising session to be synchronized can be sent to interchanger, include by what is received by interchanger The control message of session to be synchronized is sent to centralized session synchronization equipment.It should be noted that a control message includes only One session to be synchronized.

Specifically, the control message comprising session to be synchronized can be packaged by load-balancing device, and will be after encapsulation The control message comprising session to be synchronized be sent to interchanger, by interchanger will after the encapsulation that received include meeting to be synchronized The control message of words is sent to centralized session synchronization equipment.

For example, the control message comprising session to be synchronized can be encapsulated as vxlan format by load-balancing device.Interchanger Receive load-balancing device transmission be encapsulated as the control message comprising session to be synchronized of vxlan format after, it is not right The control message comprising session to be synchronized after the encapsulation carries out decapsulation or dissection process, but is directly encapsulated as this The control message comprising session to be synchronized of vxlan format is sent to centralized session synchronization equipment.Certainly, the application only with It is illustrated for above-mentioned, load-balancing device is not limited to this packaging method of the control message comprising session to be synchronized.

As another preferred embodiment of the invention, control report is sent to centralized session synchronization equipment by interchanger Text may comprise steps of S204c:

Whether S204c, the state for detecting target session change；If the state of detection target session changes, lead to Cross the control message that interchanger sends the state comprising target session to centralized session synchronization equipment.Wherein, target session are as follows: It has been synchronized to the local session of centralized session synchronization equipment.

In the present embodiment, the state of the session in TCP connection, as shown in table 1.

Table 1

The state of target session may be any one state in above-mentioned TCP state machine, and the state of target session is all In the form of message, load-balancing device is sent to by interchanger, thus, load-balancing device is detecting target session State change after, can to interchanger send comprising target session change after state control message, by interchanger The control message of state after the change comprising target session received is sent to centralized session synchronization equipment.It needs to illustrate , one controls state after the change that message includes a unique target session.

Specifically, the control message of state after the change comprising target session can be packaged by load-balancing device, And the control message of state after the change comprising target session after encapsulation is sent to interchanger, it will be received by interchanger The control message of state is sent to centralized session synchronization equipment after the change comprising target session after encapsulation.

For example, the control message of state after the change comprising target session can be encapsulated as vxlan by load-balancing device Format.Interchanger receives shape after the change comprising target session for being encapsulated as vxlan format that load-balancing device is sent After the control message of state, not to the control message of state after the change comprising target session after the encapsulation carry out decapsulation or Dissection process, but the control message that this is directly encapsulated as to state after the change comprising target session of vxlan format is sent To centralized session synchronization equipment.Certainly, the application is only illustrated for above-mentioned, and load-balancing device is to including target The packaging method of the control message of state is not limited to this after the change of session.

It should be noted that there is no stringent execution time sequencing between step S204c and step S204a-S204b.It is right For a load-balancing device in system for cloud computing, as long as load-balancing device stores a session, and the session is Meet the session of preset synchronous condition, so that it may send to centralized session synchronization equipment comprising the session by interchanger Control message.As long as load-balancing device detects that the state of target session changes, so that it may by interchanger to concentration Formula session synchronization equipment sends the control message of state after the change comprising target session.

S204e, the host CPU core of centralized session synchronization equipment is according to preset hash algorithm, to the attribute of the second session Carry out Hash calculation, according to calculated result, the selection target CPU core from the CPU core of centralized session synchronization equipment.

After the host CPU core of centralized session synchronization equipment has determined corresponding second session of control message, host CPU core can be with Hash calculation is carried out according to attribute of the symmetrical hash algorithm to step the second session, obtains the Hash characteristic value of the second session；Root According to the Hash characteristic value of the second session, according to preset selection rule, in addition to host CPU from centralized session synchronization equipment local The corresponding target CPU core of the second session is selected in other CPU cores other than core.

It should be noted that target CPU core is other other than host CPU core in centralized session synchronization equipment local Some CPU core in CPU core.The corresponding unique target CPU core of second dialogue.

S204f, the target CPU core of the host CPU core scheduling steps S204e of centralized session synchronization equipment is according to the second session Carry out synchronizing information.

For the case where the second session includes session by step S204b control message, centralized session synchronization is set After standby host CPU core selects target CPU core, target CPU core can be initialized the second session.Specifically, target CPU Core can distribute memory space for the second session, and the memory of dispatching concentration formula session synchronization equipment local stores the second meeting Words, for example, target CPU core can store the five-tuple letter of the second session with the memory of dispatching concentration formula session synchronization equipment local Breath.

For the case where the second session is step S204c target session, the host CPU core of centralized session synchronization equipment After selecting target CPU core, target CPU core can store target session with the memory of dispatching concentration formula session synchronization equipment local Change after state.

It, can be by the target CPU core of step S204e by the second session after step S204f in a kind of implementation Overtime initial time is updated to synchronizing information and completes the moment.The second session is executed at destruction to which target CPU core can wait Reason.

When it is possible to further be originated by the target CPU core of step S204e according to the time-out of updated second session It carves, whether the session timeout duration of the second session of detection reaches preset duration, if the session timeout duration of the second session reaches pre- If duration, the second session is destroyed.

Specifically, to save the free memory of centralized session synchronization equipment, and improve centralized session synchronization and set The standby managerial ability to the session for being synchronized to centralized session synchronization equipment local, target CPU core can periodically detect the The session timeout duration of two sessions, the overtime initial time of when time-out of the second session a length of second session to current time when It is long.If the session timeout duration of the second session reaches preset duration, then it is assumed that the corresponding TCP connection of the second session has disconnected, Target CPU core can destroy the second session.
