Embodiment Construction

[0043] Before elaborating the technical solutions of the embodiments of the present invention in detail, a network control architecture based on a Software Defined Network (SDN, Software Defined Network) is briefly described first.

[0044] figure 1A schematic diagram of a network control architecture applied to the method for determining routing information in an embodiment of the present invention; figure 1 As shown, the network control architecture includes SC and DC; DC is used to implement intra-domain routing control and resource management; SC is used for inter-domain coordination and resource scheduling to achieve multi-domain intercommunication, especially the configuration of intercommunication ports, etc. . Each domain requires at least one DC; and between multiple domains requires at least one SC. The DC and SC exchange signaling through the DC northbound interface to implement unified SC scheduling. The northbound interface generally uses an information model o...

Abstract

The embodiment of the invention discloses a routing information determination method, a node, a system and a storage medium. The method comprises the steps that a first node sends a network abstraction request to a second node, wherein the network abstract request carries optimization target information; and the first node obtains abstract node information from the second node, and determines routing information based on the abstract node information, wherein the abstract node information meets the optimization target information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, node, system and storage medium for determining routing information. Background technique [0002] When a service is provisioned, depending on the type of service, the optical transport network usually needs to perform routing calculation according to different constraints or optimization objectives. [0003] According to the Abstraction and Control of Traffic Engineered Networks (ACTN, Abstraction and Control of Traffic Engineered Networks) model of the Internet Engineering Task Force (IETF, The Internet Engineering Task Force), there are currently two main ways to calculate cross-domain routing: [0004] The first method is to complete the cross-domain routing calculation through the cooperation of the inter-domain controller (SC) and the intra-domain controller (DC); the SC does not save the intra-domain topology, but only calculates the inter-domain r...
