Distributing method, controller, device, and system for virtual network

Abstract

An embodiment of the invention provides a distributing method, a controller, a device, and a system for a virtual network. A lessee sends to a leaser a leasing request for leasing a virtual network resource, and the leasing request carries a network parameter value required to be satisfied by the virtual network resource required to be leased by the lessee. The leaser according to the network parameter value carried in the received leasing request, when determining that allocation of the virtual network resource satisfying the network parameter value to the lessee is enabled, allocates the virtual network resource satisfying the network parameter value to the lessee, and sends to the lessee a leasing feedback message notifying the lessee of successful leasing of the virtual network resource. The efficiency of virtual network allocation to the lessee by the leaser is improved, and modification of the leased virtual network according to the self requirement of the lessee can be flexibly performed. The invention relates to the field of communication technology.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, controller, device and system for distributing a virtualized network. Background technique [0002] In the prior art, many enterprises or individuals need to designate communication lines between network nodes to transmit data, so they can lease communication lines between designated network nodes from operators. That is to say, when an enterprise or individual needs to lease the communication line from point A to point B, the enterprise or individual can lease the communication line from point A to point B as a tenant from the operator (tenant). In the line leasing method, the operator as the outgoing tenant will lease the entire bandwidth of the communication line between point A and point B to the tenant, which is not only expensive, but also if the tenant does not need the full bandwidth from point A to point B, It will cause waste of bandwidt...

Problems solved by technology

[0006] Embodiments of the present invention provide a virtualized network allocation method, controller, device, and system to solve the problem of low efficiency when lessors allocate virtualized networks for tenants in the prior art, and the inability to flexibly adapt to the needs of tenants at any time. The problem that requires modification of the leased virtualized network
