A method of SDN-based traffic monitoring and business service quality assurance strategy

Abstract

The invention discloses a method for SDN-based traffic monitoring and business service quality assurance strategy, comprising the following steps: a. Create a network topology structure under the SDN architecture, configure an Openflow switch, and establish a connection between the switch and an SDN controller; b. The SDN controller has an open northbound API interface; c. The application system program obtains complete device information and link information; d. According to business requirements, input the services that need to be guaranteed; e. According to the source and destination addresses of the business flows, transmit Enter the algorithm class to calculate the scheduling path, and generate the current network optimal scheduling path; f, import the scheduling path in e into the policy generation class, combine the business guarantee strategy in d, combine and generate the scheduling flow table and send it to the switch; g . According to the scheduling flow table in f, add a data transmission queue for the switch port. The present invention guarantees the stable operation of network services to the greatest extent, the efficient utilization of link bandwidth, and the maximum optimization of the entire network performance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for SDN-based flow monitoring and business service quality assurance strategy. 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 part of the Internet protocol cluster defined by the IETF (Internet Engineering Task Force, Internet Engineering Working Group). 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), which provide a series of powerful operation instructions for monitoring network information, and c...

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
