Method for traffic monitoring and business service quality guarantee strategy based on SDN

Abstract

The invention discloses a method for a traffic monitoring and business service quality guarantee strategy based on SDN. The method comprises the following steps: a. creating a network topology under the SDN architecture, configuring an Openflow switch, and establishing a connection between the switch and an SDN controller; b. providing an open northbound API interface on the SDN controller; c, obtaining, by an application system program, complete device information and link information; d, inputting the business to be guaranteed according to the business requirements; e, according to a sourcedestination address of the service flow, transmitting an algorithm class to calculate a scheduling path, and generating the optimal scheduling path of the current network; f. transmitting the scheduling path in e into a strategy generation class, generating a scheduling flow table in combination with the business guarantee strategy in d, and issuing the scheduling flow table into the switch; and g. adding a data transmission queue to a switch port according to the scheduling flow table in f. By adoption of the method disclosed by the invention, the stable operation of the network business, theefficient use of the link bandwidth and the maximum optimization of the whole network performance are maximally guaranteed.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an SDN-based flow monitoring and service quality assurance strategy method. Background technique [0002] SNMP (Simple Network Management Protocol, Simple Network Management Protocol) is a very popular network management method under the traditional network architecture. The SNMP protocol is a part of the Internet protocol suite defined by IETF (Internet Engineering TaskForce). Its goal is to manage the software and hardware platforms produced by many manufacturers on the Internet. Therefore, SNMP is deeply influenced by the Internet standard network management framework. SNMP uses SMI (Structure of Management Information, management information structure) and MIB (Management Information Base, management information base), they provide a series of powerful operating instructions for monitoring network information, conform to the communication requirements of TCP / IP, and...

Problems solved by technology

[0004] Traditional routing protocols use the shortest path policy to forward traffic, regardless of network status and actual business needs, so that important services in the current network are disturbed by subsequent traffic, or subsequent key business needs cannot be met, affecting the experience and quality of private network users. to feel

Using advanced routing configuration is not only cumbersome to configure, but also cannot achieve end-to-end business guarantee and cannot meet the growing business needs
