Abstract

The invention discloses a distributed network tracing system and method based on an SDN. According to the invention, topology acquisition with low energy consumption and routing forwarding based on load balancing are realized through network design; according to the invention, label marking and path backtracking are realized through the traceability method, a label is added to each data packet inthe label marking stage, and the forwarding path of the data packet is reconstructed by extracting the label information segment in the path backtracking stage, so that fine-grained and high-accuracynetwork traceability is directly and accurately realized. According to the invention, the resource consumption is reduced, the load balance is realized, the network performance is improved, and the fine-grained and high-accuracy network traceability is realized. Network tracing is an effective means for maintaining network security, and design and implementation of a traceable network provide a good environment for subsequent deployment of a network security mechanism.

Description

technical field [0001] The invention relates to the technical field of computer network management, in particular to an SDN-based distributed network traceability system and method. Background technique [0002] With the development of information technology, the network scale in today's world is getting larger and larger, the network traffic is increasing, and the network structure is becoming more and more complex. The traditional network architecture has poor adaptability and low service efficiency due to its decentralized network control, complex network coordination, closed network equipment, and independent network protocols. Traditional networks have great difficulties in network management, and it is difficult to innovate in providing network services to users. Therefore, a new network architecture SDN (Software Defined Network) came into being. [0003] In the network environment of traditional networks, it is difficult to trace the source of data packets. SDN is...
