Abstract

The invention discloses an IPv6 network flow monitoring method and system based on an SDN. The IPv6 network flow monitoring system comprises a switch, a terminal device and an SDN controller. The switch forwards an IPv6 data packet in a network; the terminal device comprises a terminal host and a monitoring device. The SDN controller comprises a topology management module, an equipment managementmodule, a route calculation module, a forwarding rule installation module and a monitoring strategy processing module. A user inputs a monitoring strategy into the SDN controller. The SDN controller converts the strategy into a node or a link in the network through the monitoring strategy processing module. Information provided by the topology management module and the equipment management moduleis acquired. A shortest path from a monitoring target to monitoring device is determined by using a routing calculation module, a flow forwarding rule is installed in a switch on the shortest path through a forwarding rule installation module, and the switch forwards flow information of the monitoring target to the monitoring equipment according to the forwarding rule. According to the invention,the IPv6 network flow can be efficiently and accurately monitored in real time, and the method has extremely strong adaptability and flexibility.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an SDN-based IPv6 network flow monitoring method and system. Background technique [0002] With the depletion of IPv4 addresses and the huge demand for network addresses from the development of new technologies such as the Internet of Things, it is difficult for the existing IPv4-based Internet to meet the various needs of practical applications. The development of the Internet based on the IPv4 protocol to the next-generation Internet based on the IPv6 protocol has become an irresistible trend, and the research and construction of the next-generation Internet has also become a research hotspot in the field of computer networks. Compared with the IPv4 protocol, a remarkable feature of the IPv6 protocol is that the capacity of the address space has been greatly expanded. Large-capacity address space and complex network environment bring huge challenges to IPv6 netwo...
