Embodiment 1

[0060] Please refer to image 3 , the embodiment of the present invention provides an SDN-based IDC network egress traffic balance adjustment method, the method is used to adjust the egress traffic from the IDC network to the public network, the IDC network such as figure 2 As shown, it includes: a data center edge network element DPE, a traffic analysis device and an SDN controller connected to the DPE, and a policy control device connected to the traffic analysis device and the SDN controller; the DPE is connected to the public network Multiple public network edge network element CPEs are connected through multiple egress links. The embodiment of the present invention can be used to balance and adjust the egress traffic of the IDC network according to the granularity of the AS. The method may include:

[0061] 301. The policy management and control device sends grouping information of a plurality of preset AS (autonomous domain) groups to the SDN controller, and the groupin...

Embodiment 2

[0095] Please refer to Figure 5 , the embodiment of the present invention also provides another SDN-based IDC network egress traffic balance adjustment method, the method is used to adjust the egress traffic from the IDC network to the public network, the IDC network such as figure 2 As shown, it includes: DPE, a traffic analysis device and an SDN controller connected to the DPE, and a policy control device connected to the traffic analysis device and the SDN controller; the DPE communicates with multiple CPEs in the public network Multiple egress link connections. The embodiment of the present invention can be used to adjust the traffic of the egress bandwidth of the SDN-based IDC network according to the granularity smaller than that of the AS, that is, according to the granularity of the IP (Internet Protocol, Internet Protocol) network segment. The method may include:

[0096] 501. The policy control device sends VIP information to the traffic analysis device, and rece...

Embodiment 3

[0128] In some embodiments of the present invention, an SDN-based IDC network egress traffic balance adjustment method is also provided, the method is used to adjust the egress traffic from the IDC network to the public network, and the IDC network is as follows figure 2 IDC network shown.

[0129] The method may include: steps 301 to 305 in the first embodiment; and steps 501 to 504 in the second embodiment. Wherein, steps 301 to 305 can be performed first, and then steps 501 to 504 can be performed; or in reverse, steps 501 to 504 can be performed first, and then steps 301 to 305 can be performed; or in other order.

[0130] For more details, please refer to the content recorded in Embodiment 1 and Embodiment 2.

[0131] In the embodiment of the present invention, first, the network traffic is quickly and roughly adjusted, that is, adjusted according to the AS granularity, and the adjustment accuracy reaches about 5%; then, the network traffic is precisely fine-tuned, that i...

Abstract

An SDN-based IDC network egress traffic balance adjustment method, device and system to solve the technical problem in the prior art that the IDC network egress traffic cannot be balanced and adjusted. In some feasible implementation manners of the present invention, the method includes: the policy management device sends group information of at least one AS group to the SDN controller, and the group information is used by the SDN controller to generate an AS filtering policy and sends it to the DPE, Obtain the AS flow information that DPE counts according to the AS filtering strategy, and generate a flow adjustment strategy according to the AS flow information, and the flow adjustment strategy is used to indicate that the flow of the destination AS group is adjusted to the destination egress link; send the flow adjustment strategy to the SDN controller , the traffic shaping policy is used by the SDN controller to control the DPE to perform egress traffic shaping.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an SDN-based IDC network egress flow balance adjustment method, device and system. Background technique [0002] In the era of cloud computing, a data center (Data Center, DC) network faces many challenges. In a traditional IDC (Internet Data Center, Internet Data Center) network, the network and business are separated. Due to the separation of networks and services, the traditional IDC network is manually configured by the administrator through the command line or the network management system. It is a static network itself. Therefore, service deployment is very inefficient and dynamic adjustment cannot be realized. Moreover, due to the separation of network and business, traditional IDC network customization capabilities are weak and the adjustment period is long. It often takes several years of feature and architecture adjustments and the introduction of new equipment ...
