Abstract
An optical switch control method and an apparatus are disclosed, to reduce impact on access performance by time overheads of optical link switching. The method includes: receiving an optical link establishment request sent by a computation node; determining whether the first optical link that needs to be established conflicts with the existing optical link; and if the first optical link that needs to be established conflicts with the existing optical link, determining whether to allow establishment of the first optical link, and establishing the first optical link if the establishment of the first optical link is allowed; or establishing the first optical link if the first optical link that needs to be established does not conflict with the existing optical link.
