Embodiment Construction

[0042] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0043] refer to figure 1 The overall framework of the present invention is shown in , the main part of the strategy obtains the required data through the northbound interface, and sends the data to the application layer for processing, making full use of the programmability of the network, and avoiding the congestion of the network through the northbound interface The interface is used to deliver the implementation, specifically, it is implemented by the protocol between the control layer and the data link layer. The advantage of the invention is that network administrators only need to configure and deploy to realize the functions conveniently, so that the underlying controller and network are transparent to administrators. figure 2 is a schematic diagram of the framework of the reliability-based routing strategy. All three parts are deployed on the control layer....

Abstract

The invention discloses a data plane abnormity processing method in a software defined network. For fault and congestion problems in a data plane of the SDN, the robustness of network service can be still ensured in a mode of reasonably allocating or reallocating bottom layer resources under the condition that the fault and congestion problems occur. According to the specific method, routing strategies are called according to demands through utilization of high logic centralized visualization characteristics of the SDN, the balance and robustness of bottom layer links are ensured in real time; when demands are issued to flow again, the purpose of reducing south interface time delay is realized in a mode of modifying flow tables as little as possible; after the congestion occurs, a strategy is adjusted, when links reach a threshold, the strategy is adjusted, the selection of the threshold is related to history bandwidth change, and the purpose of increasing a flow acceptance rate, reducing a packet loss rate and the time delay by searching new paths for specific flow demands; and according to the method, through utilization of the programmability and openness of the SDN, the adaptability of most controllers is satisfied through software.

Description

technical field [0001] The present invention relates to the research on control functions in software-defined networks, and in particular to a method for processing data plane exceptions in software-defined networks; aiming at the problems of faults and congestion in data planes in SDN (Software Defined Network, software-defined network) architectures, a Judgment and processing, making full use of the programmability and global controllability of SDN. Background technique [0002] With the continuous expansion of computer networks, the Internet has developed from an early local resource sharing platform to today's global data communication network. To solve many problems faced by the existing TCP / IP architecture, research on the future Internet is carried out on a large scale, including SDN technology based on OpenFlow. ONF (Open Network Foundation), which believes that the ultimate goal of SDN is to provide a complete set of programming interfaces for software applications...
