Feature Issue on High Availability in Optical Networks

After many years of research and industry efforts, ultralong-haul (ULH) technologies for DWDM transport are maturing, and carriers are deploying them for high capacity and capital savings. Unlike opaque optical networks, it is still uncertain how best to restore an all-optical ULH network after failure. This paper focuses on this issue and proposes a standby restoration scheme and its variants with different restoration speed and associated restoration cost. Our observations suggest that the proposed hot standby scheme would yield both faster restoration and cost efficiencies compared with other schemes.
