Embodiment Construction

[0090] The present invention is further described below in conjunction with accompanying drawing:

[0091] 1. Modify the source code of the receiving end software switch

[0092] The switch directly connected to the host that needs to be guaranteed should be an OpenvSwitch software switch. The following steps introduce the process of modifying the source code:

[0093] (1) Identify duplicate data packets

[0094] ISO (International Organization for Standardization, International Organization for Standardization) has formulated the OSI (Open System Interconnection, Open System Interconnection) model, which divides the work of network communication into 7 layers, namely physical layer, data link layer, network layer, and transmission layer. layer, session layer, presentation layer, and application layer. Among them, the transport layer provides end-to-end services between host application processes, and is the core of the entire protocol hierarchy. It is solely responsible for...

Abstract

The invention discloses a reliable transmission method based on an SDN, relating to the technical field of network communication. The method is mainly applied to a computer network, an information center network and the like. In order to improve a fault-free operation time of the SDN and improve the reliability of network transmission, the adaptive calculation and the simultaneous transmission of data through multiple paths are carried out according to a network resource use condition based on the SDN, at the same time, redundant repeated data packets are processed in a receiving end software switch. Through the above mode, the reliability of network data transmission can be effectively improved, the possibility of network interruption or delay caused by a link failure is reduced, the fault-free operation time of the network is improved, and better quality of network service is provided for users.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a reliable transmission method based on an SDN network. Background technique [0002] With the rapid development of the Internet, various businesses have put forward higher requirements for the timeliness and reliability of network transmission. Generally, a single path is used for transmission in the network transmission process. Once a physical or logical failure occurs on the transmission path, it will affect the normal data transmission. In the case of a very large network, when a network failure occurs, if the network administrator manually configures the solution, it will take a lot of manpower and material resources, and the recovery time will be long. [0003] Software-Defined Networking (SDN) is an emerging dynamic, easy-to-manage, and adaptable innovative architecture. Its core technology, OpenFlow, decouples the data forwarding plane from the control pl...
