Granted: 2008-04-29
Abstract: Dans un système de télécommunications à étalement du spectre (10) prenant en charge des services de télécommunication à transmission amont et aval de paquets de données par rafale, on rencontre généralement des difficultés du fait de la génération de niveaux d'interférence inacceptables issus de plusieurs transmissions simultanées de paquets de données. La solution retenue ici consiste à faire organiser sélectivement par le système (10) un échéancier d'accès pour les transmissions de paquets de données de station mobile amont et un échéancier de remise pour les transmissions de paquets de données aval. Pour la liaison amont, l'échéancier est transmis à plusieurs stations mobiles (16) dans une trame courante (par exemple, la trame n) et identifie la ou les stations mobiles (16) qui sont autorisées à faire une transmission de paquets de données amont dans une trame suivante (par exemple, la trame n+1). Seules les stations mobiles (16) autorisées à avoir accès à la trame suivante (n+1) transmettent ensuite leurs paquets de données (ou des partie de ceux-ci) à la station de base (12) pendant cette trame suivante (n+1). Dans le sens aval, une notification de remise prévue est communiquée à des stations mobiles (16) de destination dans une trame courante (n). Le système (10) effectue ensuite une remise en aval, conformément à l'échéancier, à destination des stations mobiles (16) dans une trame suivante (n+1).

Title: Method of validation and host buffer allocation for unmapped fibre channel frames
Inventor: ROACH BRADLEY
IPC: H04L49/901
Filed: 1999-03-24
Granted: 2003-09-16
Abstract: A method of validation and host buffer allocation for unmapped fibre channel frames. More particularly, the invention encompasses a method of validating unmapped frames, each including a header and a payload, including receiving a frame (500) as a current frame; determining if the current frame is a first frame in a sequence (502), and if so, saving the header and payload of the current frame in a buffer (504), and otherwise determining if the current frame is a next expected frame in the sequence (508), then saving the payload of the current frame in the buffer after the payload of the prior frame (512);  determining if the current frame is a last frame in the sequence (510), and if so, sending a message to a host indicating receipt of the complete sequence (518); if the current frame is not the next expected frame in the sequence, then saving the header and payload of the current frame in the buffer (520), and sending a message to the host indicating receipt of a partial sequence (522). The host CPU is interrupted when either a complete sequence is received, or a partial sequence is received, followed by a frame from a different sequence. The host CPU may then process the concatenated payload of the sequence. The invention is particularly useful for processing TCP/IP  frames in a Fibre Channel network.

Abstract: An apparatus and method are described for combining optical amplification and dispersion compensation in a Raman ampli-fier. A Dispersion-Managing Raman Am-plifier (DMRA) combines Raman amplification with dispersion compensation by select-ing the length and dispersion of the gain fiber to balance the dispersion of the link. This gain fiber is also single-mode at the signal and pump wavelengths. The pumping level is adjusted to balance the losses from the gain fiber and transmission link, while the pumping configuration is selected to remain within the 3dB loss length for the pumping light. When the amplifier is split into two segments, the two segments may be joined by an isolator, a gain equalization element, and/or an optical add/drop multiplexer. For WDM transmission systems based on dispersion-shifted fiber (DSF), operation in the "vi-olet band" between 1430-1530 nm is based on Raman amplification. By using a DMRA, a dispersion and nonlinearity managed system can be implemented. In particular, 4WM does not phase match in such a system, and modulation instability is absent in the transmission link. Furthermore, gain equalization can be added to the DMRA by cascading one or two Mach-Zehnder frequency filters. The invention also includes a method for symmetrically adding channels below and above the C-band, the gain tilt within the C-band can be minimized.  Therefore, a roughly equal number of channels should be placed in the short-wavelength S-band and the long-wavelength L-band to minimize the Raman energy exchange in the C-band. Also, whereas C- and L-bands can be amplified using erbium-doped fiber amplifiers, the S-band can use either discrete or distributed Raman amplifiers. To minimize the interaction between pumps for different bands, alternate band pumps can be spatially dispersed and/or cross-polarized. The distributed Raman amplification can be achieved by pumping the transmission line with discrete laser diodes or by a Raman oscillator.
