Problems solved by technology

[0002] At present, the Internet has the following problems: first, routing is based on the destination IP address and the shortest path, ignoring the requirements of the available link capacity of the network and the packet flow itself, such as some links are overloaded or congested, while other links are under utilization. The bandwidth utilization rate of the entire network link is not high; secondly, the current IP technology hopes to support a wide range of services (such as voice and video, etc.), but the current IP service cannot guarantee the service quality of these services
[0006] In the current traffic engineering solution, since the main function of the router is the IP layer forwarding function, in the above process, only some IP layer indicators (such as link bandwidth) can be negotiated, and the indicators for obtaining links are relatively small, and the final decision The forwarding link of may not be the optimal forwarding link

Embodiment 1

[0027] In view of the problems in the prior art, the first embodiment of the present invention provides a traffic scheduling method based on service types, which is applied to at least a traffic analysis device, a traffic scheduling server, and various network devices (such as routers) in the backbone network. In the network of figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention. The traffic analysis device is located between the provincial network outlet and the backbone network. The traffic scheduling server may specifically include multiple traffic scheduling servers to share the processing workload, and the traffic scheduling server and each The flow analysis equipment is connected with each network equipment in the backbone network.

[0028] In the above application scenarios, such as figure 2 As shown, the method includes the following steps:

[0029] Step 201: The traffic scheduling server obtains the flow information of v...

Embodiment 2

[0065] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a traffic scheduling system based on service types, which includes:

[0066] The traffic scheduling server is used to obtain the traffic information of various service types that need to be transmitted in the backbone network, and obtain the link information of each link in the backbone network; and use the traffic of the various service types Information and the link information of each link to determine the transmission link of the traffic of each service type in the backbone network; and notify all the transmission links of the traffic of each service type in the backbone network. The network devices in the backbone network; network devices are used to transmit the traffic of the service type on the transmission link in the backbone network according to the traffic of the service type.

[0067] In the embodiment of the present invention, the system further include...

Embodiment 3

[0070] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a traffic scheduling server, such as image 3 As shown, the traffic scheduling server includes: a service state sensing module 11, a link state sensing module 12, a traffic scheduling module 13, and a policy issuing module 14. The traffic scheduling server also includes a first interface, a second interface, and a third interface, The first interface is the interface between the traffic scheduling server and the traffic analysis device, the second interface is the interface for reading the link status between the traffic scheduling server and the network equipment in the backbone network, and the third interface is the traffic scheduling server and the backbone network. For the interfaces that issue forwarding policies between network devices, the second interface and the third interface can be physically integrated but logically separated.

[0071] The service stat...

Abstract

The invention discloses a traffic scheduling method, system and equipment based on business types. The method includes: a traffic scheduling server acquires traffic information of various business types that need to be transmitted in the backbone network, and acquires the traffic information of each chain in the backbone network. The traffic scheduling server uses the traffic information of various service types and the link information of each link to determine the transmission link of the traffic of each service type in the backbone network; the traffic scheduling server divides the traffic of each service type The transmission link in the backbone network notifies each network device in the backbone network, and each network device in the backbone network transmits the traffic of the service type on the transmission link in the backbone network according to the traffic of the service type. In the embodiment of the present invention, bandwidth utilization can be improved, link bandwidth can be allocated on demand, service experience can be guaranteed, and traffic scheduling can be differentiated.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a traffic scheduling method, system and equipment based on service types. Background technique [0002] The Internet currently has the following problems: First, routing is based on the destination IP address and the shortest path, ignoring the network's available link capacity and the requirements of the packet flow itself, such as some links are overloaded or congested, while other links are in use Insufficient rate, resulting in low utilization of the entire network link bandwidth; second, the current IP technology hopes to support a wide range of services (such as voice and video, etc.), but the current IP services cannot guarantee the quality of these services. Based on the above problems, IP technology considers adding flow control (or called flow engineering) technology to provide a direct flow control mechanism. [0003] Traffic engineering is used to avoid the c...
