Description
Technical Field
The invention relates to the technical field of routing switches, in particular to a router realizing virtualization based on docker and a method thereof.
Background
A virtual router (vrouter) is a software function that replicates in software the functionality of hardware-based layer 3 internet protocol (ip) routing. Virtual routing is a form of network function virtualization (nfv) that translates the functionality of traditional hardware-based network devices into software, rather than running on standard commercial off-the-shelf (copies) hardware. This can reduce hardware costs and facilitate hardware interoperability without the need for a dedicated hardware platform.
Docker is an open source application container engine, so that developers can pack their applications and dependence packages into a portable container, and then distribute the container to any popular Linux machine or Windows machine, and can also realize virtualization, and the containers completely use a sandbox mechanism and do not have any interface.
The invention provides a new scheme for realizing a virtualized router by using a docker mode as a supplement to the existing scheme for realizing the virtualized router.
