Looking into the future, this paper presents the effects of having packets of large sizes, called XLFrames (XLFs), in a network. The analysis is motivated by the fact that the Internet is soon to witness stupendous amounts of traffic that have to be processed and switched at amplifying line rates; and this brings forth multiple challenges in the form of energy efficiency, network performance and end-host...
We describe the dimensioning and benchmarking of packet transport networks with aggregated link capacities up to the Tbit/s range, using a circuit-switching (cross-connect) infrastructure below packet-switching nodes. The different network solutions to be evaluated are designed to carry large numbers of high-definition video and other data streams, with upper bounds on packet latency and packet loss...
Accurate performance evaluation and network dimensioning are required for the design and the deployment of new telecommunication networks based on packet-switching technologies (e.g., Ethernet, IP, G/T-MPLS, etc.). In this context, network engineers need simple, efficient and realistic traffic models. In this paper we investigate traffic modeling based on the coefficient of variation CoV(t) of the...
We propose a new optical metro-access ring concept featuring a flexible color management for efficient network operation. Experimental results show that 1 hub, up to 8 nodes and 80 Gbit/s capacity without optical amplification are achievable.
We experimentally validated the concept of transparent (without regeneration) waveband-based optical backbone networks through a 32×10Gbit/s transmission over 3600km of TeraLight™ fiber including sub -equipped optical cross-connects and taking into account networks constraints on dispersion map and power equalisation.
We experimentally validated a new transparent monitoring method based on asynchronous under-sampling enabling eye-diagram reconstruction and BER estimation. It gives very accurate BER estimation in presence of chromatic dispersion and non-linear effects without requiring knowledge of the bit rate
