ICTON 2011 2ND DAY - Random notes

SESSION TuC3 RONEXT III

Survivable Impairment Aware Traffic-grooming and re-generator placement with shared connection-level protection
C. Gao, H.C. Cankaya, A.N. Patel, J.P. Jue, X. Wang, Q. Zhang, P. Palacharla, M. Sekiya

Protection in the connection level x in the light-path level.
Electric backplane: grooming card, line card. Client card.
Transponders (10, 40, 100 Gbps) The cost increases less than the capacity in Gbps.
Reduced signalling, control traffic reduction for hybrid approach of light-path and connection level restoration.

When grooming there is also regeneration since the signal must pass through electronic processing.


Survivable cross-layer virtual topology design using a hyper-heuristic approach
F. Corut Ergin, A Yayimli, A Sima Uyar

An heuristic over a lower level heuristic is used to select which low level heuristic is better to be used.
Ant colony to find a survivable light-path topology.


Cost dependency on protection of optical access networks for dense urban areas
C. Mas Machuca, J. Chen, L. Wosinska

FTTH - PON
Protection in access networks can be highly costly.
Protection until remote node x protection until the user.
cost by deciding previous protection or late reaction.
