Description

technical field

[0001] The invention belongs to the category of network technology, and is a method for configuring an optical channel connection for data transmission in an optical network. Background technique

[0002] At present, there are two more realistic optical switching methods used in all-optical networks. One is circuit switching with wavelength routing, that is, automatic switching optical network (ASON) based on connection, and the other is optical burst switching (OBS). ). Automatically Switched Optical Network (hereinafter referred to as ASON) introduces an independent control plane into the optical network to implement dynamic configuration and connection management, so as to automatically and dynamically allocate optical channels according to user needs. The core technologies of the ASON architecture include signaling protocols for establishing, maintaining, and dismantling management of distributed connections; routing protocols for providing routing servi...
