    摘要: A packet-switched communications network (PSN) includes a multiplicity of nodes (Ni) adapted to switch streams of packets benefiting from circuit emulation services, known as CES packets. The network uses a particular method of resynchronizing the CES streams. According to that method, for a CES stream intended to take an associated path (CE) from an ingress node (N1) passing through a set of nodes including a subset of nodes adapted to resynchronize CES streams selectively, effective resynchronization of said stream by a node selected from said subset is conditioned by a value representative of the cumulative jitter suffered by said stream as far as that node.

    摘要: In order to be able to use a semiconductor light amplifier of conventional type and operating under gain saturation conditions while nevertheless providing constant gain for an optical signal to be amplified, the device comprises means for producing a compensation light wave and coupling means for injecting the optical signal to be amplified and the compensation light wave into the amplifier. The compensation light wave presents amplitude modulation such that when combined with the optical signal to be amplified the overall amplitude modulation is eliminated or at least attenuated. The device is applicable to optical transmission systems operating at a single wavelength or with wavelength division multiplexing.

The first request includes a number of physical IT resources allocated for a plurality of customer edges. The second equipment sends a first response to the first equipment with a first part of physical IT resources allocated, and sends a second request to a datacenter for additional physical IT resource(s).

    摘要: The invention relates to a laser device for optical packet data transmission. Such devices are basically known in the art and comprise a laser light source for outputting a laser light beam and a laser driver for driving said laser light source. The laser device further comprises an optical modulator means for modulating a packet data stream onto said laser light beam. The optical modulator means presently available on the market, only have a low extinction rate; consequently residual light is output by said optical modulator means, even if a logical zero shall be transmitted.
