In Transparent optical networks (TONs), the data signals remain in the optical domain for the entire transmission path, creating a virtual topology over the physical connections of optical fibers. Due to the increasingly high data rates and the vulnerabilities related to the transparency of optical networks, TONs are susceptible to different physical layer attacks, including high-power jamming attacks...
Optical network is playing a vital role to fulfill the demand of bandwidth hungry applications. Optical circuit switching (OCS), Optical packet switching (OPS), and optical burst switching (OBS) techniques have been proposed to provide high capacity link in optical domain. Dynamic optical circuit switching (DOCS) is the new paradigm which involves dynamism in OCS. It is the most practical and cost...
The hierarchical routing infrastructure in automatic switched optical network (ASON) is researched. Three operational algorithms MLLR (multi-layer least loaded routing algorithm), MLCR (multi-layer least congestion routing algorithm) and MROB (multi-layer routing algorithm based on backtracking) are proposed. In these algorithms, the resource coordination and balancing of multi-domain and multilayer...
