Current network switching architectures require communication with a high er level network control plane, which can be slow to reroute communications, resulting in unacceptable losses of communications for customers. Examples embodiments of the present invention reroute communications faster detecting optical power of an optical signal at optical switches coupled via optical communication paths, and causing at least one optical communication path bet ween a first optical switch and second optical switch to switch to an altern ative optical communication path, in part, through physical layer triggering in an event optical power at at least one of the first or second optical sw itches falls below a threshold level. Switching in response to physical laye r triggering may result in reduced switching times and, consequently, faster restoration of communications to customers after a network fault interrupti on. |
