Specifically, sending device can E-Packet according to the physical interface that the instruction information in forwarding table indicates.It sends Equipment the instruction information of physical interface can be arranged in forwarding table according to the ratio of 1:1 (multiplex roles are exactly 1:1:1 ...).

For example, when forwarding table has 16 instruction information (to be referred to as 16 list items, a list item is that a physics connects The instruction information of mouth, is used to indicate the physical interface of transmitting message), LAG includes two physical interfaces, i.e. interface 1 and interface 2.

				Interface 1	Interface 2	Interface 1	Interface 2
Interface 1	Interface 2	Interface 1	Interface 2
				Interface 1	Interface 2	Interface 1	Interface 2

However, the parameter due to each physical interface is different, if only carried out according to 1:1 (multiplex roles are exactly 1:1:1 ...) Load balancing will affect LAG available bandwidth, influence network performance.

In view of the above problems, the embodiment of the present application dexterously proposes to determine each physical interface according to the parameter of physical interface Load balancing ratio, and according to the load balancing ratio of each physical interface pass through LAG transmitting message.In this way, The embodiment of the present application can flexibly determine the load balancing of physical interface according to the parameter of physical interface, avoid existing skill The problems in art is able to ascend transmission performance.

Hereinafter, it is non-limiting as example, the method for the transmitting message of the application implementation is described in detail in conjunction with Fig. 2.Fig. 2 institute The method shown can be executed by sending device, specifically, method as shown in Figure 2 includes:

210, sending device obtains the forwarding ginseng of each physical interface in the interface group for including at least two physical interfaces Number.

The interface group can be for example the set of LAG or other physical interface, hereinafter, for ease of description, only with Interface group is described for being LAG, but the embodiment of the present application is not limited to this.

For example, the retransmitting paramater of the physical interface may include at least one of following parameter:

It should be understood that noun " retransmitting paramater " can indicate a kind of index of physical interface in the embodiment of the present application, for example, can To indicate the bandwidth for being used for transmission data, or the state when being used for transmission data, such as packet loss, propagation delay time or error code Rate etc.." parameter " or " the first parameter " or " transmission performance " etc., the embodiment of the present application can also be stated as by being somebody's turn to do " retransmitting paramater " It is not limited to this.

It should also be understood that " each physical interface " can also be described as " each physical interface " or " the in the embodiment of the present application One physics " etc., any one physical interface in interface group can be indicated by being wherein somebody's turn to do " the first physical interface ", and the application is real Example is applied to be not limited to this.

220, which determines the load point of each physical interface according to the retransmitting paramater of each physical interface Load ratio.

It should be understood that the load balancing ratio of the first physical interface can indicate in the case where interface group full and down, first The message of physical interface carrying accounts for the ratio of the message of entire interface group carrying group.Wherein, which can be to connect Any one physics, that is, interface in mouth group.

230, which passes through the interface group transmitting message according to the load balancing ratio of each interface.

Optionally, as one embodiment, the retransmitting paramater of the physical interface is the bandwidth of physical interface, described each The load balancing ratio of physical interface and the bandwidth of each physical interface are positively correlated.

For example, having 4 physical interfaces in LAG, the bandwidth of 4 physical interfaces is respectively 1GE, 2GE, 5GE, 10GE, So the load balancing ratio of 4 physical interfaces can be 1:2:5:10, and the embodiment of the present application is not limited to this, as long as each The load balancing ratio of physical interface is directly proportional to bandwidth.

In existing way, the load balancing ratio for being set as 4 physical interfaces for 4 physical interfaces is 1:1:1: 1.If this mode load will lead to the interface packet loss of 1GE bandwidth beyond 1Gbps.Therefore, so that each physical interface is born Carrier band width is up to 1GE, and such case will lead to the physical interface bandwidth waste of 2GE, 5GE, 10GE, limit entire LAG's Total bandwidth.

And load balancing ratio is set 1:2:5:10 by the embodiment of the present application.Enable to the load of each physical interface Bandwidth most significantly so that entire LAG shows maximum available bandwidth.

Optionally, as one embodiment, the retransmitting paramater of the physical interface is the packet loss of physical interface, described each The packet loss of the load balancing ratio of a physical interface and each physical interface is negatively correlated.

Optionally, as one embodiment, the retransmitting paramater of the physical interface is the bit error rate of physical interface, described each The load balancing ratio of a physical interface and the bit error rate of each physical interface are negatively correlated.

Optionally, as one embodiment, the retransmitting paramater of the physical interface is the propagation delay time of physical interface, described The load balancing ratio of each physical interface and the propagation delay time of each physical interface are negatively correlated.

Optionally, as another embodiment, the load balancing ratio of the first physical interface is first physical interface pair First ratio of the first instruction information answered in multiple instruction information, the multiple instruction information is carried on forwarding table, described Instruction information in forwarding table is used to indicate the physical interface that the selects when sending device sends message by LAG, and described the One instruction information is used to indicate and selects first physical interface when sending device sends message by LAG, and described first Physical interface is any one physical interface in the physical interface group；

In 230, the sending device is according to the first ratio-dependent message pair to be transmitted of first physical interface The instruction information answered,

Specifically, sending device can be according to forwarding table transmitting message in a kind of feasible implementation.The forwarding With the instruction information (being referred to as list item) of fixed format in table, each indicates that information is used to indicate a physics and connects Mouthful, instruction information can be the mark of physical interface or label of physical interface etc., as long as instruction information can indicate that its is right The physical interface answered, the embodiment of the present application are not limited to this.

In practical applications, sending device can inquire forwarding table and obtain the instruction information for sending message, be believed according to instruction Cease the physical interface transmitting message of instruction.

It is described below when retransmitting paramater is the bandwidth of physical interface, how to determine each physical interface in forwarding table Indicate the example of the ratio of information.

Accordingly, as another embodiment, the retransmitting paramater of the physical interface is the bandwidth of physical interface, the transmission Equipment determines the initial number of the corresponding instruction information of each physical interface according to the following formula:

Mi=┖ Vi*Z ┛

When the sum of the initial number ∑ Mi in the forwarding table that all physical interfaces occupy is equal with Z, each physics The number for the instruction letter that interface occupies is identical as the instruction initial number of information；Alternatively,

When the sum of the initial number for indicating information in the corresponding forwarding table of all physical interfaces ∑ Mi is less than Z, the hair Send equipment be randomly assigned or according to the retransmitting paramater of the physical interface distribute Z in addition to ∑ Mi remaining instruction information, obtain It must distribute as a result, indicating that the initial number of information determines in the forwarding table occupied according to the allocation result and each physical interface The number of instruction information in the corresponding forwarding table of each physical interface.

For example, as shown in figure 3, in first pass LAG transmitting message, or one interface of addition/deletion or interface in LAG When bandwidth changes, there are 4 physical interfaces in LAG, the bandwidth of 4 physical interfaces is respectively 1GE, 2GE, 5GE, 10GE, is turned The size delivered is 32, that is, has 32 list items (instruction information).

It is assumed that being equal to it to each interface assignment if not considering that interface corresponds to the list item number in forwarding table is integer Bandwidth accounts for the forwarding-table item number of total bandwidth ratio, is the most reasonable method of salary distribution, bandwidth can be made completely to make full use of.I.e. 1GE assigns to the forwarding-table item of 1/ (1+2+5+10) * 32=32/18=16/9, and so on, 2GE assigns to 32/9,5GE and assigns to 80/ 9,10GE assign to 160/9 forwarding-table item, in this way when the wide message rotation of filled band, are equivalent to and forwarded 18/ using each list item 32 be about the message of 0.5625Gbps.

But forwarding-table item population should be integer in practical application, therefore, to these scores in the embodiment of the present application It is rounded downwards, so that 1GE physical interface obtains 1 list item, 2GE physical interface obtains 3 list items, and 5GE physical interface obtains 8 List item, 10GE obtain 17 list items.Divide to fall 29 list items in this way, remaining 3 list items are not fallen by point.

When calculating each one list item of interface reallocation later, unit bandwidth (bandwidth that each list item indicates).Such as 1GE has a list item at present, then reallocating one, entry number 2, each list item indicates the bandwidth of 0.5Gbps；2GE divides again It is 4 with one, each list item indicates the bandwidth of 0.5Gbps；It is 9 that 5GE, which reallocates one, each list item expression 5/9, about The bandwidth of 0.56Gbps；It is 18 that 10GE, which reallocates one, and each list item indicates 10/18, the about bandwidth of 0.56Gbps.

That is, when these interfaces are reallocated one in forwarding table, if 1GE or 2GE are assigned to forwarding table, When flow is greater than 0.5Gbps* forwarding table number (0.5*32=16Gbps), the two interface flows can overflow.Similarly, if 5GE or 10GE are assigned into forwarding table, when flow is greater than 0.56Gbps* forwarding table number (0.56*32=17.92Gbps), this Two interface flows can overflow.It will be apparent that obtained total bandwidth is bigger by after unit bandwidth big interface assignment when reallocating.

Therefore, Priority Queues can be added in they by the embodiment of the present application, be sequentially 10GE, 5GE, 2GE, 1GE, they Reallocation unit bandwidth is 5/9,5/9,1/2,1/2.

10GE is added in the forwarding-table item of next sky to according to this queue and is calculated its new reallocation one The unit bandwidth of list item, 10/ (18+1) is about 0.53Gbps, smaller than 5GE, bigger than 2GE, is put it to behind 5GE.At this time 30 list items are divided to have fallen, have sequentially been 5GE, 10GE, 2GE, 1GE, their reallocation unit bandwidth is 5/9,10/19,1/2,1/ 2。

The 5GE of queue heads is allocated and is calculated again, be 5/ (9+1) is 0.5Gbps, puts it to the back 10GE.This Time-division has fallen 31 list items, is sequentially 10GE, 5GE, 2GE, 1GE, their reallocation unit bandwidth is 10/19,1/2,1/2, 1/2。

10GE is allocated.Having occupied all 32 list items, distribution at this time terminates.Allocation result can be obtained as 10GE occupancy 19 list items, unit bandwidth 10/19Gbps；5GE occupies 9 list items, unit bandwidth 5/9Gbps；2GE occupies 3 list items, Unit bandwidth is 2/3Gbps；1GE occupies 1 list item, unit bandwidth 1Gbps.Actual bandwidth is the minimum value 10/ in them 19Gbps*32, about 16.84Gbps.

Sending device can be forwarded according to this forwarding table in the embodiment of the present application later.Compared to equal than load When sharing, each interface assigns to 8 list items, and maximum bandwidth 1/8*32=4Gbps, bandwidth has obtained reasonable utilization, on the LAG The flow of 12.84Gbps can be distributed without packet loss more.

It should be understood that indicating the ratio of information in the corresponding forwarding table of each physical interface has been determined in the embodiment of the present application After example, the arrangement situation of this 32 instruction information is not limited in the forwarding table, for example, 10GE occupies 19 list items, unit band Width is 10/19Gbps；5GE occupies 9 list items, unit bandwidth 5/9Gbps；2GE occupies 3 list items, unit bandwidth 2/ 3Gbps；1GE occupies 1 list item.

The forwarding table can be as shown in table 2 or shown in table 3.

Optionally, the forwarding table or be other forms, the embodiment of the present application is not limited to this.That is the forwarding table The instruction information of middle interface can arbitrarily arrange, as long as the ratio of the corresponding instruction information of 4 physical interfaces is above-mentioned acquires Ratio.
