Ethernet's success in local-area networks (LANs) is fueling the efforts to extend its reach to cover metro and long-haul networks. A key enabler for using Ethernet in the carrier's network is its ability to efficiently sup port multipoint-to-multipoint (MP2MP) services. MP2MP service is the core underlying structure to enable standard Ethernet services such as Ethernet virtual private networks (E-VPNs)...
Wavelength-division multiplexing (WDM) optical networks are characterized by maturity, high-capacity, agility, flexibility, and cost-efficiency. Today, optical transmission rates are increasing from 10 Gbit/s to 100 Gbit/s which increases the network's flexibility for capacity provisioning. We study the problem of dimensioning optical WDM networks under traffic growth. Particularly, we study link-rate...
We study the problem of determining the optimal transmission range (TR) for high-rate carrier-grade Ethernet. We show that, since traffic grooming can be combined with signal regeneration, optimal TR value depends on the traffic volume.
