| HTTP business | 600Mbps | 500Mbps | 100Mbps |
| P2P business | 1900Mbps | 1000Mbps | 900Mbps |
| Instant messaging business | 10Mbps | 5Mbps | 5Mbps |
| Route webmaster information service | 0.01Mbps | 0.005Mbps | 0.005Mbps |
In the embodiment of the present invention, flow scheduling server obtains the link information of each bar link in backbone network, specifically include but not limited to as under type: the network equipment in backbone network obtains the link information (it is network layer leading indicator) of each bar link in backbone network by the link service condition of each bar link in monitoring backbone network, and the link information of each bar link in backbone network is reported flow scheduling server, the link information of each bar link that the network equipment in backbone network reports is received by flow scheduling server.

| The network equipment 1-network equipment 2 | 55ms | 1ms | 0.005% | 30% |
| The network equipment 1-network equipment 3 | 60ms | 0.5ms | 0.005% | 40% |
| The network equipment 2-network equipment 3 | 35ms | 0.5ms | 0.005% | 25% |
Step 202, the flow information of flow scheduling server by utilizing miscellaneous service type and the link information of each bar link determine the transmission link of the flow of each type of service in backbone network.
In the embodiment of the present invention, the flow information of flow scheduling server by utilizing miscellaneous service type and the link information of each bar link determine the transmission link of the flow of each type of service in backbone network, specifically include but not limited to as under type: the flow information of flow scheduling server by utilizing miscellaneous service type determines that often kind of type of service needs the flow transmitted in backbone network, the link information of each bar link is utilized to determine the flow that every bar link can carry, and the flow that the flow utilizing often kind of type of service to need to transmit in backbone network and every bar link can carry determines the transmission link of the flow of each type of service in backbone network.
Such as, when the flow information of miscellaneous service type is as shown in table 1, flow scheduling server determines that the flow that HTTP service needed is transmitted in backbone network is 600Mbps, determine that the flow that P2P service needed is transmitted in backbone network is 1900Mbps, determine that the flow that instant messaging service needed is transmitted in backbone network is 10Mbps, determine that route webmaster information service needs the flow transmitted in backbone network to be 0.01Mbps.
Such as, when the link information of each bar link is as shown in table 2, the flow that flow scheduling server determination link (network equipment 1-network equipment 2) can carry is link bandwidth * (1-30%), this link bandwidth is the link bandwidth between the network equipment 1-network equipment 2, and its bandwidth value can be pre-configured on flow scheduling server; Determine that the flow that link (network equipment 1-network equipment 3) can carry is link bandwidth * (1-40%), this link bandwidth is the link bandwidth between the network equipment 1-network equipment 3, and its bandwidth value can be pre-configured on flow scheduling server; Determine that the flow that link (network equipment 2-network equipment 3) can carry is link bandwidth * (1-25%), this link bandwidth is the link bandwidth between the network equipment 2-network equipment 3, and its bandwidth value can be pre-configured on flow scheduling server.
Based on the flow that often kind of type of service needs the flow that transmits in backbone network and every bar link to carry, flow scheduling server determines that link that the flow that can carry is greater than the flow that type of service needs transmit in backbone network is the transmission link of flow in backbone network of this type of service.
Further, when the link that the flow that can carry is greater than the flow that type of service needs transmit in backbone network is multiple link, flow scheduling server by utilizing often plants the process that flow that type of service needs to transmit in backbone network and the flow that every bar link can carry determine the transmission link of the flow of each type of service in backbone network, specifically include but not limited to as under type: flow scheduling server selects the flow that can carry to be greater than the link (i.e. multiple link) of the flow that type of service needs transmit in backbone network, and determine that (this chain index is carried in link information for the chain index corresponding to link of each selection, and this chain index specifically includes but not limited to one of following or combination in any: time delay, shake, packet loss), afterwards, flow scheduling server needs to select the chain index corresponding to link to meet the flow transmission link backbone network in of link as this type of service of chain index required for this type of service.
Wherein, can in advance for each type of service configure chain index required for each type of service, as shown in table 3, a kind of example of chain index required for pre-configured each type of service, now chain index is time delay, shake, packet loss; Further, flow scheduling server needs to select the chain index corresponding to link (it corresponds to content shown in table 2) to meet the flow transmission link backbone network in of link as this type of service of chain index required for this type of service (it corresponds to content shown in table 3).
Table 3
| Type of service | Delay requirement | Shake requirement | Packet loss requirement |
| HTTP business | 70ms | 1ms | 0.01% |
| P2P business | Nothing | Nothing | Nothing |
| Instant messaging business | 65ms | 1ms | Nothing |
| Route webmaster information service | 60ms | 0.5ms | 0.005% |

In a kind of specific implementation of the embodiment of the present invention, flow scheduling server can perform step 202 and subsequent step when backbone network generation link congestion (the bandwidth utilization rate as link in backbone network is greater than pre-determined threshold), do not perform step 202 and subsequent step when link congestion (the bandwidth utilization rate as link in backbone network is less than pre-determined threshold) does not occur backbone network, process according to existing mode.
Step 203, the transmission link of the flow of each type of service in backbone network (forwarding strategy that namely type of service is corresponding) is informed to each network equipment in backbone network by flow scheduling server.
In the embodiment of the present invention, the transmission link of the flow of each type of service in backbone network is informed to each network equipment in backbone network by flow scheduling server, specifically includes but not limited to as under type:
Corresponding relation between the transmission link of the flow of type of service and this type of service in backbone network is informed to each network equipment in backbone network by policybased routing mode by mode one, flow scheduling server.
Wherein, which goes for traditional network equipment (as router), by adopting policybased routing mode, the corresponding relation between the transmission link of the flow of type of service and this type of service in backbone network is directly informed to each network equipment in backbone network by flow scheduling server.
Corresponding relation between the transmission link of the flow of type of service and this type of service in backbone network is informed to each network equipment in backbone network by stream table mode by mode two, flow scheduling server.
Wherein, which goes for SDN(Software Defined Network, software defined network) network architecture, by adopting stream table mode (as: this stream table mode is specifically as follows the stream table mode based on transport layer port number), the corresponding relation between the transmission link of the flow of type of service and this type of service in backbone network is directly informed to each network equipment in backbone network by flow scheduling server.
Step 204, in backbone network, each network equipment transmits the flow of this type of service according to the transmission link of flow in backbone network of type of service; Such as, when the transmission link of flow in backbone network of HTTP business is link 1, then each network equipment needs the flow being transmitted HTTP business by link 1.
In the embodiment of the present invention, in backbone network, each network equipment is after receiving the service message needing transmission, by the link-layer identification to service message, and/or Network Layer identities (includes but not limited to ether, VLAN(Virtual Local Area Network, VLAN), MPLS(Multi-Protocol Label Switching, multiprotocol label switching), IP etc.), and/or transport layer mark is distinguished, the type of service of this service message can be known, then the flow (i.e. corresponding service message) of this type of service can be transmitted according to the transmission link of the flow of the type of service of this service message in backbone network.
In sum, in the embodiment of the present invention, the transmission link of the flow of each type of service in backbone network can be determined based on the link information of each bar link in the flow information of the miscellaneous service type transmitted in backbone network and backbone network, thus carry out the flow scheduling of IP network based on type of service (as HTTP business, instant messaging service, P2P business etc.); In addition, can carry out flow scheduling based on time delay, shake, packet loss, the indication range of consideration is much larger than traditional traffic engineering; In addition, carry out traffic engineering work by special flow scheduling server, its scheduling accuracy, flexibility are greater than traditional traffic engineering; Further, aforesaid way can improve bandwidth availability ratio, and distribution according to need link bandwidth, ensures business experience, differentiation flow scheduling, and avoid some link Overload or congested, and the problems such as other link utilization deficiency.
