Multi-Flow Transmitter Based on Polarization and Optical Carrier Management on Optical Polymers

Abstract: We propose a novel multi-flow transmitter concept capable of controlling the number, type, wavelength, and destination of the generated optical flows depending on the client traffic. The concept is based on the selection of the number of optical carriers per flow and the selection between single- and dual-polarization flows. We demonstrate the proof-of-concept combining two commercial In-Phase/Quadrature (IQ) modulators with two prototype polymer circuits, which integrate three tunable lasers for flexible wavelength allocation, four thermo-optic switches for flexible optical routing on-chip, and elements for polarization handling on-chip. We incorporate this transmitter inside an optical node, and we investigate one-flow scenarios with dual-carrier or dual-polarization quadrature phase shift keying (QPSK) modulation, and two-flow scenarios based on two independent QPSK signals. The transmitter and node configuration are controlled by a software-defined optics platform. We demonstrate dynamic operation at 28 GBd and error-free coherent transmission over 100 km of the standard single-mode fiber.

Setting the course for a green Internet.

Abstract: In his Perspective “Toward a green Internet” (29 March, p. [1533][1]), D. Reforgiato Recupero reflects (partially) some of the ideas and even the wording of the ECONET project's Description of Work (DoW) ([ 1 ][2]), first published on 6 September 2010. However, the general philosophy of the

Method and system for simulating communications networks, object and computer program product therefor

Abstract: A method for simulating a telecommunications network through objects that model a respective set of network modules or devices provides for the insertion, for every module or device of the set, of at least one respective interfacing object with the other modules of the set. The above interfacing object has an external side and an internal side with respect to the module or device. Such external side has a character that is independent of idiosyncrasies of such module or device and is therefore uniform for all modules or devices. When there are a plurality of different implementations of the same module or device, it is possible to provide both a unique interfacing object for all different implementations, and a respective interfacing object for every single implementation.

Method and system for data management in communication networks

Abstract: Method for operating a node of a communication network comprising a plurality of peer-to-peer nodes, the node being linked with predetermined neighbour nodes among said plurality of peer-to-peer nodes, the method comprising: a) storing, on a first storage area, node information indicative of predetermined data required by the node to become an information provider node; b) waiting to receive from at least one information provider node of the neighbour nodes describing information of data that can be provided by said information provider node; c) at the receipt of said describing information from said at least one information provider node, checking in said first storage area if the data that can be provided by said at least one information provider node match at least in part the predetermined data required by the node; d) in the affirmative, deleting in the first storage area the node information indicative of the matching data; e) in the negative, forwarding the describing information received in c) to at least one of the plurality of peer-to-peer nodes.
