SESSION We.B3 GOC III
Power Consumption analysis of opaque and transparent optical core network
A, Autehrieth, A.K. Tilwankar, C. Mas Machuca, J-P. Elbers
Transparent Optical Networks are increasingly more economical over 20Tbps traffic volume. Under that volume opaque network is more economical due to grooming.
The cross point is at an average demand value of 16-30 Gbps in the considered network.
Cross-layer Re-configurable optical network: Fast failure recovery in test-bed for routing algorithm
C. Ware, C.P. Lai, D. Brunina, W. Zhang, A.S. Garg, B. G. Bathula, K. Bergman
Lambda stripping: WDM payload +header wabelengths.
A failuer would trigger the switcher to an alternate port.
The impact of optical networks considering physical impairments, CAPEX and energy consumption
K. Georgakilas, A. Tzanakazi
Wavelength sharing for bkp path with common links assuming the respective primary paths are disjoint.
SESSION We.C3 WAOR III
Dynamic impairment- aware optical networking: Some experimental results of the EU DICONET project
S. Spadaro, J. Perelló, F. Agraz, M. Angelou, S. Azodolmolky, Y. Qin, R. Nejabati, D. Simeonidou, I. Tomkos
A Q-factor is estimated by a Q-tool. A PPD has info on physical impairment on the network
The established connection executed by the RSVP collects information on the physical impairments on the links on the calculated path and this info is to be used by the Q-tool.
It is and enhanced PCE E-PCE = PCE + NPOT
Centralized light-path establishment.
Off-line algorithms for routing, modulation level and spectrum assignment in elastic optical networks
M. Klinkowski, K. Wakowiak, M. Jaworski
Elastic Optical Networks (EON)
Off-line algorithm. for routing, modulation level and spectrum assignment - RMLSA
Flexible operation: provision of just the resource requirements of a resource
Frequency slots (Jinno et al 2010)
RMLSA problem (Chistodoupoulos et. al 2011)
In a RWA algorithm a whole wavelength is assigned. In a RMSLA problem contiguous slots are assigned.
Experimental implementation of efficient multicast processes: towards carrier Ethernet networks and all-optical multicast
A. Valentí, N. Avallone, A. Pompei, F. Matera, G. Tosi Beleffi
Carrier Ethernet ad all optical multicast
MPLS-TP (transport profile)
Provider backbone bridges
E-Line, E-LAN, and E-tree services
layer 2 multicast by carrier Ethernet network
E-LAN service for multicast traffic live IPTV
Employing Ethernet spanning tree protocols in an integrated hybrid optical network
R. Veisllari, S. Bjørnstad
Hybrid optical network: employs circuit switched path and packet switched path
Optical Labeling through parametric amplification
M.L.F. Abbade, A.L.A. Costa, J.D. Marconi, V.V. Cardoso, H.L. Fragnito, E. Moschim
New optical labeling technology
Label is inserted all optically
Label and payload are emitted a part, in the same BW and different time (strategy for transmission of payload and label)
