Abstract
The design of survivable all-optical mesh networks based on bidirectional wavelength division multiplexing (WDM) self-healing rings (SHRs) to supply complete protection against any single link failure requires an efficient solution. This paper proposes a shared protection algorithm called shared protection by concatenated rings (SPCR) using self-healing capability and a pre-configuration mechanism. Our algorithm protects and recovers any single link failure with very little capacity, faster detection, and recovery time on failures in mesh networks. The comprehensive computer simulation shows that the protection cost is reduced up to about three times and the protection delay is improved up to about five times comparing to short leap shared protection (SLSP) scheme which is known to be effective.
