In survivable elastic optical networks, multi-path protection combined with traffic squeezing
has gained attention. Link-disjoint multipath routing (LD-MPR) and bandwidth squeezing …

Wide-area optical networks face significant transmission challenges due to the relentless
growth of bandwidth demands experienced nowadays. Network operators must consider the …

In this paper, we propose an evolutionary multiobjective regenerator placement strategy for
elastic optical networks (eMORP). The proposed optimization strategy uses the genetic …

The problem of regenerator assignment (RA) in translucent optical networks consists in
segmenting a lightpath into several transparent segments, each of which linked by 3 R …

Quality of transmission of optical signals, which are propagated beyond their transparent
reach, is ensured by re-amplification, re-timing and re-sha** (3R-regeneration) at certain …

In a dynamically reconfigurable wide-area translucent network, the pre-deployment of
regenerators at few sites has its advantages due to the increased system optimization and …

This work proposes a new regenerator allocation algorithm, named Circuit Invigorating
Regenerators Assignment (CIRA) algorithm. The CIRA selects the regenerators to be …

Provisioning strategies for Translucent Elastic Optical Networks (EONs) should consider
both spectrum and transponder costs. End-to-end connections that support user demands …

In this article, we propose an auxiliary-graph-based methodology to best assess regenerator
assignment choices in translucent elastic optical networks. The proposed methodology …

In a Translucent Elastic Optical Network, an optical signal can be propagated beyond its
transparent reach by 3R regeneration (re-sha**, re-timing and re-timing) at certain nodes …
