Abstract

The present invention discloses a method, a system and an apparatus for discovering a network function virtualization (NFV) resource pool topology. The method comprises the steps that after a monitor proxy is implanted in a virtual switch and a virtual network function (VNF) of an NFV resource pool, the monitor proxy receives network planning information delivered by a software defined network (SDN) controller, wherein the network planning information comprises a network planning topology; the monitor proxy acquires, according to the network planning topology, information of a neighbor node of a node at where the monitor proxy is; and the monitor proxy detects a condition of network connection between the node at where the monitor proxy is and the neighbor node, and feeds back the condition of network connection to the SDN controller, so as to enable the SDN controller to discover a current network topology of the NFV resource pool according to the condition of network connection of all nodes in the NFV resource pool. The method is applicable to discovering the NFV resource pool topology.

Description

technical field

[0001] The invention relates to the field of intelligent pipes, in particular to a method, monitoring agent, SDN (Software Defined Network, Software Defined Network) controller and system for realizing NFV (Network Function Virtualization, Network Function Virtualization) resource pool topology discovery. Background technique

[0002] NFV realizes the decoupling of software and hardware through virtualization technology, abstracts the network element function into an independent VNF ​​(Virtual Network Function, virtual network function), and deploys it on a unified platform based on standard servers, storage, and switches. If you can understand the network topology of NFV and adjust the computing resources of the corresponding VNF, you can further realize the elastic adjustment of network capabilities.

[0003] The existing topology discovery method is to enable LLDP (Link Layer Discovery Protocol) on network devices, but this method can only discover hosts a...
