Wherein, the inventive method can be adjusted each step order according to actual needs.
The concrete application of the sharing business load method that the present invention proposes, the method is by using the through street to carry out sharing business load by handoff technique, be applicable to carry out to the outbound between the wide area network by local area network (LAN) the transmission of business datum, wherein, this local area network (LAN) can be for (outbound is two greater than 1 number to the number of the outbound between the wide area network, article three,, article four, or more), among the present invention, describe as two as example take local area network (LAN) to the outbound between the wide area network, as shown in Figure 2, networking structure figure for sharing business load method of the present invention, these two local area network (LAN)s are respectively ISP 1 (Internet Service Provider to the outbound between the wide area network, ISP) and ISP 2, wherein, ISP provides Internet access business to users, information service, operator with value-added service, this operator includes but not limited to China Telecom, China Netcom, Chinese Education and Research Net, CSTNet, cable modem, be that different operator is for providing outbound between local area network (LAN) and the wide area network, so that local area network (LAN) can be according to the strategy of self, outbound by different operators sends to business datum in the wide area network, and by wide area network business datum is sent in the purpose network.Certainly, an operator also can be for providing many outbounds between local area network (LAN) and the wide area network, so that local area network (LAN) is according to the strategy of self, many outbounds that provide by this operator send to business datum in the wide area network, and by wide area network business datum is sent in the purpose network, among the present invention, provide outbound to describe as example take different operators as local area network (LAN) with between the wide area network.Among Fig. 2, network 1 is different local area network (LAN)s with network 2, terminal 1 and terminal 2 are in network (local area network (LAN)) 1, terminal 3 and terminal 4 are in network (local area network (LAN)) 2, among the present invention, business datum need to be sent to terminal in the network 2 by wide area network with the terminal in the network 1 (including but not limited to terminal 1 and terminal 2), for example, terminal 1 and terminal 2 send to terminal 3 in the network 2 by wide area network with business datum, the IP address of this terminal 3 is IP 1, and namely the purpose IP address of the business datum of terminal 1 and terminal 2 transmissions is IP 1.Above-mentioned sharing business load method may further comprise the steps as shown in Figure 3:
Step S301, the forwarding unit in the local area network (LAN) receives the business datum of self terminal.
Wherein, this local area network (LAN) is network 1, this terminal is the terminal in the network 1, include but not limited to terminal 1 and terminal 2, this forwarding unit includes but not limited to router, among the present invention, take terminal 1 a large amount of purpose IP address is described as example as the business datum of IP 1 sends to terminal 3, this terminal 1 can directly send to router with business datum, also can business datum be transmitted to router by switch.Among the present invention, this business datum is to transmit in the mode of data flow, i.e. a plurality of packets composition data stream together.
It is the active link address of business datum that step S302, the router in the network 1 select the address of the highest outbound of numerical priority value.
Router in this network 1 is take router one as example, outbound between network 1 and the ISP 1 is link A, outbound between network 1 and the ISP 2 is link B, this active link address is the address of the highest corresponding transmission equipment of outbound of numerical priority value, this transmission equipment includes but not limited to the transmission route device, for example, when the numerical priority value of the outbound A between network 1 and the ISP 1 is the highest, router one sends to business datum in the transmission route device among the ISP 1, and the address of this transmission route device is the active link address.
In this step, router one can be known the bandwidth of outgoing link A and the bandwidth of link B, and this router one can be that link A and link B distribute numerical priority value according to the bandwidth of this link A and the bandwidth of link B.Wherein, be that link A distributes the mode of numerical priority value to include but not limited to link B according to the bandwidth of link A and the bandwidth of link B: the ratio according to link bandwidth is that different links arranges different numerical priority value; Numerical value according to link bandwidth is that different links arranges different numerical priority value; Size according to link bandwidth is that different links arranges different numerical priority value; Strategy according to forwarding unit is that different links arranges different numerical priority value, identical among the detailed process of its distribution and the above-mentioned steps S102, do not repeat them here, among the present invention, to describe as example as different links arranges different numerical priority value according to the ratio of link bandwidth.
In this step, after getting access to the numerical priority value of distributing into link A and link B when router one, also need this numerical priority value is stored in this router one, for example, record and store the numerical priority value of link A and link B distribution by the mode of using form, certainly, can also store by another way the numerical priority value that link A and link B distribute.
In this step, router one also needs to obtain the number of outbound, among the present invention take outbound as link A and link B describe as example, namely the number of outbound is 2.
Step S303, router one is by using the active link address that above-mentioned business datum is sent to router two.Wherein, this router two is the router in the network 2.
Concrete, router one is by searching route table items, business datum is sent to the corresponding transmission route device in address of the highest outbound of numerical priority value, for example, when the numerical priority value of link A is the highest, router one sends to business datum in the transmission route device among the ISP 1, transmission route device among this ISP 1 (the corresponding transmission route device in active link address) is after the business datum that receives from router one, search the information (information of this destination address is the information of purpose terminal) of destination address from this business datum, this transmission route device sends to router (router two) in the purpose terminal place network (network 2) according to the information of this destination address with business datum.Wherein, after router one sent to business datum the corresponding transmission route device in address of the highest outbound of numerical priority value, this router one also needed the corresponding numerical priority value in address of the outbound that numerical priority value is the highest to subtract 1.
Wherein, router one includes but not limited to the mode that business datum sends to the corresponding transmission route device in address of the highest outbound of numerical priority value: when having stored the route table items of business datum destination address in this router one, this router one sends to business datum according to the information of the business datum destination address that records in this route table items the corresponding transmission route device in address of the highest outbound of numerical priority value; When not having the route table items of storage service data destination address in this router one, this router one sends to business datum in the mode of default route the corresponding transmission route device in address of the highest outbound of numerical priority value;
Should be specially in the mode of default route: when in the route table items of router one, not finding the destination address information of carrying in the business datum, this router one will send this business datum will use default route, this default route be take the purpose network as 0.0.0.0, subnet mask occurs as the form of 0.0.0.0, this uses the mode of default route to send business datum to be prior art, and in this not go into detail.
Step S304, router two sends to the terminal 3 that purpose IP address is IP 1 with this business datum.
Wherein, router two sends to this business datum on the terminal 3 (address is IP 1) according to the destination address information of this business datum after receiving business datum.
Step S305, router one continue to receive the business datum of self terminal, and by the active link address this business datum are sent to router two.
Concrete, when the terminal 1 in the network 1 sends a large amount of business datums to the purpose terminal, router one can constantly receive the business datum of self terminal 1, and router one all will send to router two with this business datum by the active link address, and finally be forwarded on the purpose terminal.Wherein, after router one sends to router two by the active link address with this business datum, also need the corresponding numerical priority value in active link address is subtracted 1, this corresponding numerical priority value in active link address is the address of the highest outbound of numerical priority value.
Among the present invention, router one is to adopt by the mode of flow forwarding to carry out business data transmission, receive the business datum of self terminal 1 when router one after, mating this business datum in the route table items fast, when the destination address information of carrying in this business datum has been mated corresponding information in quick route table items, directly according to this quick route table items this business datum is sent to the transmission route device, and do not need to have searched the routing table in the router one.Mating this business datum in the route table items fast, when the destination address information of carrying in this business datum is not mated corresponding information in quick route table items, router one is searched route table items, and according to this route table items this business datum is sent to the transmission route device.
Wherein, when the destination address information of carrying in the business datum is not mated corresponding information in quick route table items, router one is mating corresponding information in the route table items fast according to the destination address information of carrying in this business datum after receiving business datum.As seen, in the above-mentioned steps 1 business datum is sent to after the transmission route device, the information of in this quick route table items, just having mated terminal 3, when router one receives when mailing to the purpose terminal and being the business datum of terminal 3, all can match corresponding information from quick route table items, thereby it is above-mentioned to send to the purpose terminal by the transmission route device fast.
When terminal 1 continues to send business datum, continue the process shown in the execution in step S305, until the corresponding numerical priority value in above-mentioned active link address is for reducing to 0.
When the corresponding numerical priority value in above-mentioned active link address for after reducing to 0, the number of the outbound that gets access among the above-mentioned steps S302 is subtracted 1, and whether the numerical value of judging outbound is greater than 0, if the time, the numerical priority value of active link address is 0, the address that reselects the highest link of numerical priority value is the address of next active link, and by the address of next active link business datum is sent to the purpose terminal; Otherwise, the corresponding numerical priority value of all links is reverted to the corresponding numerical priority value of link address of determining according to link bandwidth information, and the address that reselects the highest link of numerical priority value is the active link address.
Among the present invention, outbound describes as an example of link A and link B example, the number that is outbound is 2, when the number of outbound subtracts 1, the number of this outbound is 1, and at this moment, the numerical priority value of above-mentioned active link address (link A) is 0, the address (link B) that reselects the highest link of numerical priority value is the address of next active link, namely continues the forwarding service data to the purpose terminal by the address (link B) of using next active link.
Same, when the numerical priority value of link B reduces to 0, continuation subtracts 1 with the number of outbound, and whether the numerical value of judging outbound is greater than 0, and the number of outbound is 1 at this moment, and when the number of outbound subtracted 1, the number of this outbound was 0, namely need the corresponding numerical priority value of all links is reverted to the corresponding numerical priority value of link address of determining according to link bandwidth information, and the address that reselects the highest link of numerical priority value is the active link address; Among the present invention, the numerical priority value of link A is higher than the numerical priority value of link B, continues the forwarding service data to the purpose terminal by using this link A.
For example, the bandwidth of supposing link A is 1Gbps, the address of the down hop among the corresponding ISP 1 is Ipa (address of the transmission route device among the ISP 1), and the bandwidth of link B is 100Mbps, and the next hop address among the corresponding ISP 2 is Ipb (address of the transmission route device among the ISP 2).Among the present invention, take link A and link B as example, i.e. the number n=2 of down hop.The priority that IPa is set is 100, the priority of IPb is 10, among the present invention, be that priority take IPa is 100, the priority of IPb is 10 to describe as example, the concrete numerical priority value of Ipa and Ipb is not limited to this, can be that different links arranges different numerical priority value according to the above-mentioned ratio according to link bandwidth; Numerical value according to link bandwidth is that different links arranges different numerical priority value; Size according to link bandwidth is that different links arranges different numerical priority value; Be that different links arranges different several set-up modes such as numerical priority value and arranges arbitrarily according to the strategy of forwarding unit, do not repeat them here.
Router one stores this numerical priority value in this router one into by the form of using form after the numerical priority value that gets access to as link A and link B distribution, and is as shown in table 1.

Go to the business datum that destination address is IP1 for the 100th from terminal 1 transmission, when sending to router one, router one sends to business datum on the transmission route device among the ISP 1, and the priority that IPa is corresponding subtracts 1, at this moment, the corresponding numerical priority value of Ipa becomes 0.
Router subtracts 1 with the number of down hop, after soon n will subtract 1, n=1＞0, keeping the numerical priority value of Ipa is 0, again campaigns for primary down hop, at this moment, the numerical priority value of Ipa is that the numerical priority value of 0, Ipb is 10, and namely IPb becomes primary down hop, upgrade the above-mentioned form that is stored in the numerical priority value in the router one, as shown in table 3.
Table 3
Go to the business datum that destination address is IP1 for the 101st from terminal 1 transmission, when sending to router one, router one sends to business datum on the transmission route device among the ISP 2, the priority that Ipb is corresponding subtracts 1 (the corresponding numerical priority value of Ipb becomes 9), and upgrades the above-mentioned form that is stored in the numerical priority value in the router one.
Go to the business datum that destination address is IP1 for the 110th from terminal 1 transmission, when sending to router one, router one sends to business datum on the transmission route device among the ISP 2, and the priority that Ipb is corresponding subtracts the corresponding numerical priority value of 1, Ipb and becomes 0.
Router subtracts 1 with the number of down hop, after soon n subtracts 1, and n=0, at this moment, recover the numerical priority value of Ipa and the numerical priority value of Ipb, and again campaign for primary down hop, at this moment, the numerical priority value of Ipa is 100, the numerical priority value of Ipb is 10, and namely Ipa becomes primary down hop, upgrades the above-mentioned form that is stored in the numerical priority value in the router one, this moment, this form was identical with table 1, did not repeat them here.
When receiving the business datum of self terminal 1, with continuing above-mentioned operating process, do not repeat them here.
