Specific implementation mode

The embodiment of the present invention provide it is a kind of shunting the method that reports, can by with the initial friendship that receives newdata packet Other interchangers being connected directly of changing planes report the newdata packet not reported to controller shunting, to accelerate newdata The report speed of packet avoids newdata packet congestion in initial switch.The embodiment of the present invention additionally provides corresponding friendship It changes planes, controller and system.It is described in detail separately below.

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, the every other implementation that those skilled in the art are obtained without creative efforts Example, shall fall within the protection scope of the present invention.

Refering to fig. 1, the embodiment provided in an embodiment of the present invention for shunting the method reported includes：

Controller, interchanger 1, interchanger 2, interchanger 3, interchanger 4, host A and host B, controller respectively with exchange Machine 1, interchanger 2, interchanger 3 and interchanger 4 communicate to connect, certainly, a software defined network (Software defined Network, SDN) in may include many interchangers and host, Fig. 1 is only illustrated for these.

Assuming that 1 moment of interchanger receives 10 newdata packets, the interchanger 1 in the embodiment of the present invention is initial exchange Machine, this 10 newdata packets can come from different hosts, it is assumed that the number of 10 newdata packets is respectively 1-10, is exchanged Machine 1 can cache these newdata packets, then determine whether the newdata packet not reported is more than reporting ability upper threshold, such as Fruit be more than reporting ability threshold value, it is determined that separate the newdata packet reported, it is assumed that interchanger 1 in limit of power can more than 3 newdata packets are reported, such as：Interchanger 1 reports the newdata packet that number is 1-3, then can determine that by number be 4-10 Newdata packet separate and report.

Reporting ability threshold value can be interchanger by judging that itself cpu busy percentage, newdata packet buffer Buffer's Number accounts for ratio of total Buffer numbers etc. to determine, other modes can also be used to determine that this is not limited by the present invention.

Can include the source host information for sending the newdata packet and the destination host information to be reached in newdata packet.

Controller first can send the exchange being respectively connected directly to interchanger 1, interchanger 2, interchanger 3 and interchanger 4 The information of machine, but the information of all interchangers being connected directly not necessarily is sent, for the interchanger of transmission being connected directly Information can determine that controller can judge whether the interchanger that each interchanger is connected directly empty in several ways by controller Spare time comes number of switches and priority that reasonable arrangement issues.

When controller sends the information for the interchanger being connected directly to interchanger, the openflow of an expansion can be passed through Message realizes, the number of the interchanger being connected directly with this interchanger, interchanger can be carried in openflow message It identifies, and the port numbers being connected with this interchanger.

Such as：The information of the interchanger being connected directly sent to interchanger 1 is interchanger 2, is issued to interchanger 2 straight The information for connecing connected interchanger is interchanger 1 and interchanger 3, the information of the interchanger being connected directly issued to interchanger 3 For interchanger 2.

Interchanger 1 is after determination reports 7 newdata packet shuntings, according to the interchanger being connected directly with interchanger Information, it may be determined that the interchanger of shunting be interchanger 2, moreover, interchanger 1 can also be each to separate the newly-built number reported Interim flow table item is established according to packet, the output port of the interim flow table item is set as the port of the shunting interchanger, also It is the port for setting the output port of all corresponding interim flow table items of newdata packet that separate and report to interchanger 2.

It is reported in this way, 7 newdata packets that number is 4-10 can be transferred to interchanger 2 by interchanger 1, and And when sending 7 newdata packets that number is 4-10 to interchanger 2, interchanger 1 is encapsulated in each newdata packet Identification information, identification information can be the mark of interchanger, can also be the mark of interchanger and the port numbers of interchanger.

After interchanger 2 receives 7 newdata packets that number is 4-10, it is assumed that interchanger 2 can only in limit of power Report four newdata packets of number 4-7, then interchanger 2 further according to the interchanger being connected directly with interchanger 2 information, really The fixed newdata packet that cannot report residue is transferred to interchanger 3, that is, interchanger 2 again by number is 8-10 3 it is new It builds data packet and is transferred to interchanger 3, it is assumed that interchanger 3 confirms in limit of power can report 3 newdata packets, then exchanges Machine 3 no longer reports information to the transfer of other interchangers.Interchanger 2 is sending 3 newdatas that number is 8-10 to interchanger 3 Bao Shi can encapsulate the identification information of upper interchanger 2 in newly-built stream.

In this way, 10 newdata packets are just reported by interchanger 1, interchanger 2, interchanger 3 respectively, interchanger 1 reports volume Number three newdata packets for being 1-3, interchanger 2 reports four newdata packets that number is 4-7, interchanger 3 to report number For three newdata packets of 8-10, can be held by openflow message when interchanger is to controller report newdata packet It carries.

The mark of the interchanger encapsulated in the newdata packet of transfer for interchanger can understand refering to Fig. 2A, The format of the three newdata packets for the number 1-3 that interchanger 1 reports can be tag1 (port1)+payload, and interchanger 2 reports The format of four newdata packets of number 4-7 can be tag2 (port1) tag1 (port1)+payload, interchanger 3 reports The format of three newdata packets of number 8-10 can be tag3 (port1) tag2 (port1) tag1 (port1)+payload. Wherein, tag is the mark of interchanger, and port is the port numbers of interchanger, i.e. interchanger receives the port numbers of the newdata packet.

Controller receive this 10 report information after, so that it may with according to reporting the format of information to parse number 1-3's Newdata packet derives from interchanger 1, and the newdata packet of number 4-7 experienced interchanger 2 and interchanger 1, primary source in The newdata packet of interchanger 1, number 8-10 experienced interchanger 3, interchanger 2 and interchanger 1, and primary source is in interchanger 1.

In this way, controller can be according to network topological information, each report the source host carried in information and purpose master The information of machine determines 10 respective flow table items of newdata packet, by taking newdata packet 1 therein as an example, newdata packet 1 Source host is host A, and destination host is host B, and controller is assured that the forward-path of newdata packet 1 is interchanger 1-- 4-host Bs of interchanger.Controller is determined according to the forward-path to be sent to the flow table item of interchanger 1 and is sent to interchanger 4 flow table item, the flow table item for being sent to interchanger 1 are newdata packet 1：1-interchanger of interchanger 4 is sent to interchanger 4 Flow table item is newdata packet 1：Interchanger 4- host Bs.Certainly, 1-interchanger of interchanger 4 can be specifically in above-mentioned flow table item It is set as newdata packet being sent to the port that interchanger 1 arrives interchanger 4, interchanger 4- host Bs can will be created Data packet is sent to the port that interchanger 4 arrives host B.

In this way, interchanger 1 receives flow table item newdata packet 1：It, will be by newdata after 1-interchanger of interchanger 4 Packet 1 is sent to interchanger 4, and it is newdata packet 1 that interchanger 4, which receives flow table item,：Interchanger 4- host Bs and interchanger 1 are sent out After the newdata packet 1 sent, newdata packet 1 will be sent to host B.

When interchanger 1 receive number include by 11 data packet information it is identical as the newdata packet that number is 1 When, then the flow table item for numbering the data packet for being 11 to match the newdata packet foundation for being 1 according to number is handled.

When interchanger 1 determines that the newdata packet not reported is less than reporting ability bottom threshold, delete described interim Flow table item.Such as：When reporting ability upper threshold is the 80% of central processing unit reporting ability, in the newdata not reported When packet is more than the 80% of central processing unit reporting ability, then the process that above-mentioned shunting reports is executed, if under reporting ability threshold value It is limited to the 50% of central processing unit reporting ability, then newdata packet is reduced to the 50% or less of central processing unit reporting ability When, interchanger 1 deletes the interim flow table item established before, no longer executes above-mentioned shunting and reports, but by all newdatas The work of packet is all completed by interchanger 1.

Initial exchange chance establishes interim flow table item in the embodiment of the present invention, and the specific format of flow table item is as shown in Figure 2 B, Matching domain therein, action Action include but not limited to described in Fig. 2 B：

As shown in Figure 2 B, the interim flow table item generally automatically generated is located in last flow table of initial switch.

In_port matching domains in matching domain can be the specific port of this section point, can also use wildcard (*), indicate Fail matched newdata packet from some port of this interchanger or whole port.

Other match fields in matching domain indicate other matching domains in flow table, equally can be specifically to be worth Wildcard (*) can also be used.

The priority P riority of flow table item is 0, indicates lowest priority, that is to say, that finally can just be matched to this flow table .That is, only matching can just be matched to this flow table item less than the newdata stream of other flow table items, it is sent to other interchangers It is shunted.

The corresponding instruction Instr of flow table item is write actions, is shown to be and writes action.

The corresponding action action of flow table item includes that the data packet of newly-built stream is increased tag (push of a mark Tag), modification tag values (write tag value, including No. port in switch identification and in_port), are output to some Port (output port), this port are exactly the port numbers of the initial switch obtained and the interchanger being connected directly.

It is output to the specific port which is connected with the interchanger being connected directly in newly-increased flow table item action, is not this programme The emphasis of discussion.There are many method, such as each newly-built busy extent for flowing into port and the priority according to neighbor node Deng.

The data packet that the interchanger that is connected directly is transferred to involved in the present invention carries the identification information of this interchanger, main If carrying newdata packet is in the ingress port information of this interchanger.It is by push tag and the write tag in flow table item Come what is realized, the specific format of the two actions is shown in Openflow agreements for value actions.

Tag applications are described in detail below：

In order to be identified by exchange hardware, the information of initial switch is placed on by we meets IP agreement specification It is realized in tag labels.

Some tunnel heads for being currently known can be used to realize in this kind of tag, including but not limited to the following tag head, example Such as MPLS Tag, GRE Tag, VLAN Tag, Vxlan Tag.In order to meet the needs of shifting at many levels, known to these Tunnel head preferably supports multilayer nest.

It, can will be to controller when there are many newdata packet that initial switch receives in embodiments described above The task of newdata packet is reported to turn to be assisted by being connected directly other interchangers with initial switch, to accelerate newly-built number According to the report speed of packet, newdata packet congestion is avoided in initial switch.

Refering to Fig. 3, from the perspective of interchanger, another implementation provided in an embodiment of the present invention for shunting the method reported Example include：

101, initial switch is determined to separate when the newdata packet not reported is more than reporting ability upper threshold At least one newdata packet reported.

Wherein, the newdata packet is the data packet for not being matched to flow table item in the initial switch, the stream List item is used to indicate processing method of the initial switch to the newdata packet.

Interchanger can first inquire the flow table item stored on interchanger after receiving data packet, if inquiring corresponding stream List item, interchanger will handle the data packet according to flow table item, if not inquiring flow table item, it is determined that the data packet is new Data packet is built, needs to ask the corresponding flow table item of newdata packet to controller.

The forward rule of the data packet stored on interchanger 1 can be 1-interchanger of interchanger 2, be stored on interchanger 2 The forward rule of data packet can be 2-interchanger of interchanger 3, and the forward rule stored on interchanger 3 can be interchanger 3- Host D.

102, according to the information for other interchangers being connected directly with the initial switch, described to separate reports At least one newdata packet selection is for shunting the shunting interchanger reported.

One interchanger can have several interchangers being connected directly, and load can be selected when selection shunts interchanger most One or several light interchangers are as shunting interchanger.

103, to separate that at least one newdata packet reported is corresponding to be faced described in being established on the initial switch When flow table item, the output port of the interim flow table item is set as the port of the shunting interchanger.

Which interchanger newdata packet is diverted on shunt namely for instruction and report by interim flow table item, this Sample, newdata packet will be diverted on the shunting interchanger according to interim flow table item, not have to be directed to each newdata packet Determine primary shunting interchanger.

104, according to the interim flow table item, to the shunting interchanger send described in separate report it is at least one new Build data packet, so as to the shunting interchanger by it is described to separate at least one newdata reported and wrap offer the control Device.
