Comparing OSNR based policies for an adaptive-alternative IA-RWA algorithm applied to all-optical networks

A framework for analyzing in-band crosstalk accumulation in ROADM-based optical networks

“…One set includes a number of real or planned topologies, and another set includes a number of regular topologies. The first set comprises the COST239 network (11 nodes, 26 links) [21], the Finland network (12 nodes, 19 links) [22], the NSFNET network (14 nodes, 21 links) [23], the EON network (19 nodes, 36 links) [21] and the UBN network (24 nodes, 42 links) [21]. The second set comprises star topologies (see Table 1) and other well-known regular topologies, described in Table 2.…”

Cognitive methodology for optical amplifier gain adjustment in dynamic networks

“…A detailed review of such approaches can be found in [10]. Recent works on RWA include an adaptive-alternative routing algorithm for all-optical networks that selects the route considering OSNR restrictions [11]; an ant colony optimization approach to solve the grooming, routing, and wavelength assignment problem considering mixed line rate and physical impairments [12]; and an adaptive approach to choose the most efficient forward error correction (FEC) for different lightpaths based on their individual OSNRs [13].…”
