Abstract

Disclosed in the present invention are a route configuration method and device for a PIC type of optical switch matrix. The route configuration method comprises: receiving a request for establishing a route; searching an optical switch matrix for a non-blocking path included in the request; if one non-blocking path is obtained by searching, taking the path as the route; if multiple non-blocking paths are obtained by searching, selecting a non-blocking path closest to the first or last 2x2 middle node in the optical switch matrix as the route. With the present invention, the blocking rate of establishing routes in an optical switch matrix can be reduced.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a routing configuration method and device for a PIC (Photonic Integrated Circuits, integrated optical circuit) type optical switch matrix. Background technique [0002] As an optical signal switching technology with low energy consumption and high throughput, all-optical switching technology has formed a development trend of gradually replacing electrical switching technology as a switching network. The core component of all-optical switching technology is the optical switch matrix. Among them, the PIC type optical switch matrix has been widely used in the field of optical communication network because of its integrability, high response speed and low cost. [0003] Currently, the PIC-type optical switch matrix is ​​mainly divided into strict non-blocking type and rearrangement non-blocking type according to path blocking characteristics. Strictly non-b...
