Method and system for implementing communication among heterogeneous controllers

Abstract

Embodiments of the invention provide a method and system for implementing communication among heterogeneous controllers. The method comprises: receiving a first link layer discovery protocol message transmitted by an intra-domain switch of a first domain controller; determining a second link layer discovery protocol message according to the first link layer discovery protocol message; encapsulating the second link layer discovery protocol message, thereby obtaining a southbound protocol bearing message; transmitting the southbound protocol bearing message to a super controller, so that the super controller obtains inter-domain link information; acquiring intra-domain network information of each domain controller; encapsulating the intra-domain network information, thereby obtaining a first message; and transmitting the first message to the super controller, so that the super controller obtains the intra-domain network information of each domain controller and performs communication among the heterogeneous controllers according to the inter-domain link information and the intra-domain network information. The embodiments of the invention aim at supporting cooperation among the heterogeneous controllers.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a communication method and system between heterogeneous controllers. Background technique [0002] Software Defined Network (SDN) based on a new network architecture has become a research hotspot in the network field in recent years. Among them, the control plane is the core position of the SDN architecture, responsible for the control and management of the entire underlying network. As the scale of SDN networks continues to expand, in order to manage large-scale networks, especially in heterogeneous networks, it is necessary to deploy multiple heterogeneous controllers that work together. [0003] Existing collaborative solutions for multi-heterogeneous controllers are all based on a horizontal architecture. The controllers are fully connected and share their own network information. Each controller has global network information, and the controllers are realized through data ...
