Example Embodiment

[0052] Example

[0053] figure 2 It shows the typical connection situation of IDC network of telecom operators. Generally speaking, there are three directions for the IDC exit of the city, namely the direction of the metropolitan area network, the direction of the IDC convergence network and the direction of the direct connection backbone network. Backbone network export traffic mainly comes from IDC traffic and metropolitan area network traffic. In some cities, IDC has only two directions, namely, the metropolitan area network direction and the IDC convergence network direction (such as figure 1 The status of SDN network is shown). The links are divided into two types according to whether they are directly connected to the backbone network:

[0054] Direct link:

[0055] IDC is directly connected to the export link of the backbone network, such as L3, L4, L5, L6;

[0056] The metropolitan area network is directly connected to the backbone network outlet link, such as L1, L2, L9, L...

Abstract

The invention discloses a network flow arranging system and a network flow arranging method based on a software defined network (SDN) technology, and relates to a network flow arranging strategy based on the SDN technology. The strategy schedules flow between different SDN controllers via an SDN cooperative arranger based on analysis on overall network flow direction, and meanwhile, the invention analyzes and states a network device and a framework needed for achieving unified flow arrangement. According to the strategy provided by the invention, scheduling of the network flow of an Internet Data Center (IDC) can be guided, unified arrangement of large-scale multi-domain network flows can also be guided, meanwhile, operation complexity of network staffs can be greatly reduced, a utilization rate of network bandwidth resources can be improved, and finally network agility scheduling and intelligent control capacity is optimized, and new building and capacity expansion costs of network bandwidth are reduced.

Description

technical field [0001] The invention belongs to the field of data communication networks, and in particular relates to an SDN technology-based network flow orchestration system and method. Background technique [0002] Currently, operators still manage data communication networks based on traditional network management software, mainly in the management and monitoring of network information. In terms of traffic scheduling, operators usually manually adjust BGP (Border Gateway Protocol) routing. strategy implementation. A common practice is that the operation and maintenance personnel log in to the router to manually adjust the routing policy and change the traffic flow of specific services. The operation is very complicated and the workflow takes a long time. [0003] With the introduction of SDN (Software Defined Networking, SDN) technology, the centralized control and programmable features of network functions can realize automatic scheduling of traffic in complex network...
