Abstract

The invention provides a virtual switch distributed escape method and device, and a storage medium, and is used for solving the technical problem of gateway resource and performance pressure generated by centralized processing of routing request related messages by an exit gateway. According to the method, a SDN controller issues gateway configuration information to a proxy component, the proxy component creates a virtual gateway interface and starts a monitoring daemon, a router solicitation (RS) message sent by a virtual machine is sent to the virtual gateway interface through the OVS, and the monitoring daemon assembles a router advertisement (RA) message after monitoring the RS message and sends the RA message to the virtual machine through the OVS. According to the method, the RS message is answered by a local virtual gateway interface in a distributed mode, the east-west IPv6 service of the virtual machine on the OVS can still keep normal and support the OVS of different manufacturers under the condition that the control plane fails, the pressure of the exit gateway can be reduced, the reliability of the whole network is improved, and the network bandwidth occupancy rate is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a distributed escape method, device and storage medium for a virtual switch. Background technique [0002] An IPv4 address is 32 bits (4.3 billion), and an IPv6 address is 128 bits (4.3 billion * 4.3 billion * 4.3 billion * 4.3 billion), which is enough for every grain of sand on the earth to have an address. Due to the limited IPv4 addresses, mutual access between the private network and the public network becomes very difficult. IPv6 addresses are extremely rich, and every device, car, and street lamp in the world can have an independent IP address, realizing the true Internet of Everything. [0003] After the IPv6 network in the traditional IT architecture is deployed and launched according to business requirements, if the business requirements change, it is very cumbersome to re-modify the configuration on the corresponding network devices (routers, switc...
