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. |
