We report an experimental investigation about the Quality of Service of High Definition IPTV applications in a core-access network based on a DiffServ over MPLS architecture with GBE interfaces. We show that particular traffic treatments are required in the network, especially at the edge segment in order to guarantee high QoS performance.
We propose and we experimentally demonstrate a novel fast restoration method for Gigabit Ethernet based on the wavelength recovery. It permits to route the wavelength of a broken link in another existing ling exploiting the wavelength division multiplexing of the fibre. Such a procedure is obtained by means of an optical switch, driven by a Loss of Light… (More)
