End-to-end network design and experimentation in the DISCUS project

Abstract

Abstract-This paper reports on the overall outcome of the FP7 DISCUS project, which aimed at designing end to end architectures, protocols and a physical layer exploiting Long-Reach Passive Optical Network an integrated access and metro network interconnected with a low cost flat optical core network. Our architectural modelling results show that the benefits of node consolidation on the access side extends also to the core part, by enabling a flattening of the backbone network, bringing a substantial reduction in the number of router ports. In addition we report on testbed results demonstrating end-to-end service provisioning across multiple network layers, from application down to physical layer Index Terms-access metro, network convergence, fixed mobile convergence, Long-Reach PON, flat optical core, optical island, 5G architecture, next generation multi wavelength PON.

Comparison of Erbium, Raman and Parametric Optical Fiber Amplifiers for Burst Traffic in Extended PON

“…Current physical reach in 10G-PON passive optical networks is limited to 20 kms due to chromatic dispersion and power budget allowance in direct detection systems [1].Reach extension in PON is required to extend number of users and also to consolidate physical metro-access network layers hence to reduce multiple active nodes [2].Future access networks will evolve current state-of-the-art PON to enhanced dispersion tolerable transceiver solutions using coherent and advanced digital signal processing. But to increase power budget allowance in-line amplification is required parallelly enhancing point to multipoint capacity at branching nodes.…”
