Embodiment Construction

[0023] Further detailed description of the technical solutions of the present invention will be described below with reference to the drawings:

[0024] The designer of the present invention and the concept of service perception SDN combination can be appreciated that use of the network traffic flow measurement and analysis, performance goals to achieve by controlling the flow of traffic route, for example, load balancing or a minimum overhead, as in business select the routing path more in line with business requirements, efficient and flexible forwarding path settings.

[0025] , SDN Software defined backhaul network controller acquires the status information from the node and the link protocol as outlined view of the present invention; edge node after the network flow according to the respective service features, software-defined network flow entering the backhaul network, by controlling SDN flow table issued data plane, the network traffic flow split into a plurality of stream...

Abstract

The invention relates to a service-aware software-defined backhaul network routing method, characterized in that: with software-defined network controller as the core, the state information of the nodes and links in the software-defined backhaul network is obtained, and the flow is split into several service flows according to the characteristics of each service at the edge nodes; the software-defined network controller calculates the service flow routing path with the minimum total routing cost while measuring and analyzing the service flow parameter requirements. The method of the inventionconsiders the load of the network link and the network flow splitting and other constraints in the service-aware software-defined backhaul routing method, which not only can reasonably carry out pathplanning for the service flow, but also achieves good effect in routing overhead.

Description

Technical field [0001] The present invention relates to a software-defined network (hereinafter referred to as the expression SDN) route, in particular to the network service parameters considering the scene requirements, software defined network backhaul traffic routing method based on perception. Background technique [0002] With the continuous development of information technology, terminal type of business diversification and research network into a dense network deployment brings new challenges. Business sensitivity to latency or packet loss and other parameters vary in different application scenarios, the study is important from the perspective of the business features of routing policy. Traditional network architectures lack the flexibility and scalability, there are some limitations in the face of business integration and user experience requirements. Therefore, the software-defined network (Software-DefinedNetwork, SDN) as a new type of programmable network architecture...
