Patent number: 8085789Abstract: A method for selecting packets to be switched in a collapsed virtual output queuing array (cVOQ) switch core, using a request/acknowledge mechanism is disclosed. An egress location for an ingress port is selected based on degrees of freedom for the selection mechanism. The degree of freedom can be derived from the collapsed virtual output queuing array by determining a number of egress locations to which an ingress port may send packets and determining a number of ingress ports from which an egress location can receive packets. Analyzing all the queued packets for assignment to an egress location, starting with a lesser degree of freedom and ending with a greater degree of freedom provides efficient switching allocations and acknowledgements.Type: GrantFiled: February 3, 2009Date of Patent: December 27, 2011Assignee: International Business Machines CorporationInventors: Alain Blanc, Rene Glaise, Francois Le Maut, Michel Poret

Patent number: 8009702Abstract: A communication system which consists of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master, the others are slave modules controlled by control signals derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.Type: GrantFiled: May 11, 2010Date of Patent: August 30, 2011Assignee: International Business Machines CorporationInventors: Michel Colmant, Alan Benner, Francois G. Abel, Michel Poret, Norbert Schumacher, Alain Blanc, Mark Verhappen, Mitch Gusat

Patent number: 7773602Abstract: An embodiment of the system operates in a parallel packet switch architecture having at least one egress adapter arranged to receive data packets issued from a plurality of ingress adapters and switched through a plurality of independent switching planes. Each received data packet belongs to one sequence of data packets among a plurality of sequences where the data packets are numbered with a packet sequence number (PSN) assigned according to at least a priority level of the data packet. Each data packet received by the at least one egress adapter has a source identifier to identify the ingress adapter from which it is issued. The system for restoring the sequences of the received data packets operates within the egress adapter and comprises buffer for temporarily storing each received data packet at an allocated packet buffer location, a controller, and a determination means coupled to a storing means and extracting means.Type: GrantFiled: May 20, 2008Date of Patent: August 10, 2010Assignee: International Business Machines CorporationInventors: Alain Blanc, Rene Glaise, Michel Poret, Rene Gallezot

Patent number: 7769003Abstract: A high speed data packet switch comprising input and output ports and a switch fabric to link each input port to each output port wherein each connection between input and output ports comprises a dynamic buffer memory for storing at least one data packet for a minimum specified storing time is disclosed. When a data packet is received through an input port, it is written in all individual dynamic memory buffers connected to this input port so as to have a copy of the incoming data packet ready to go through any output port to support unicast, multicast and broadcast traffic. Given the architecture of the data packet switch and its control algorithm, dynamic memory buffers neither need to be refreshed nor their contents have to be restored after reading.Type: GrantFiled: September 10, 2007Date of Patent: August 3, 2010Assignee: International Business Machines CorporationInventors: Rene Glaise, Alain Blanc, Francois Le Maut, Michel Poret

Patent number: 7706394Abstract: A system and a method to avoid packet traffic congestion in a shared-memory switch core, while dramatically reducing the amount of shared memory in the switch core and the associated egress buffers, is disclosed. According to the invention, the virtual output queuing (VOQ) of all ingress adapters of a packet switch fabric are collapsed into its central switch core to allow an efficient flow control. The transmission of packets from an ingress buffer to the switch core is subject to a mechanism of request/acknowledgment. Therefore, a packet is transmitted from a virtual output queue to the shared-memory switch core only if the switch core can actually forward it to the corresponding egress buffer. A token based mechanism allows the switch core to determine the egress buffer's level of occupation. Therefore, since the switch core knows the states of the input and output adapters, it is able to optimize packet switching and to avoid packet congestion.Type: GrantFiled: July 20, 2004Date of Patent: April 27, 2010Assignee: International Business Machines CorporationInventors: Alain Blanc, Rene Glaise, Francois Le Maut, Michel Poret

Patent number: 7668672Abstract: A method and systems for automatically adjusting the parameters of signal emitter in a synchronous high-speed transmission system, is disclosed. According to the method of the invention, the quality of a high-speed received signal is analyzed for a plurality of sets of parameter values and the one producing the best signal quality is selected. In a first embodiment, the quality of the high-speed received signal is determined by analyzing a digital eye characterizing the signal behavior, obtained by over-sampling the high-speed received signal. In a second embodiment, the quality of the high-speed received signal is determined by analyzing the behavior of the phase rotator used for data sampling. Finally, in a third embodiment, the quality of the high-speed received signal is determined by analyzing a digital eye, obtained by moving the position of a phase rotator from one end to the other and sampling data at each position.Type: GrantFiled: June 18, 2007Date of Patent: February 23, 2010Assignee: International Business Machines CorporationInventors: Alain Blanc, Patrick Jeanniot

Publication number: 20090141733Abstract: A method for selecting packets to be switched in a collapsed virtual output queuing array (cVOQ) switch core, using a request/acknowledge mechanism. According to the method, an efficient set of virtual output queues (at most one virtual output queue per ingress adapter) is selected, while keeping the algorithm simple enough to allow its implementation in fast state machines. For determining a set of virtual output queues that are each authorized to send a packet, the algorithm is based upon degrees of freedom characterizing states of ingress and egress adapters. For example, the degree of freedom, derived from the collapsed virtual output queuing array, could represent the number of egress ports to which an ingress port may send packet, or the number of ingress ports from which an egress port may receive packets, at a given time.Type: ApplicationFiled: February 3, 2009Publication date: June 4, 2009Applicant: International Business Machines CorporationInventors: Alain Blanc, Rene Glaise, Francois Le Maut, Michel Poret

Patent number: 7477685Abstract: Methods and systems for analyzing the quality of high-speed signals are provided, wherein a high speed signal is sampled simultaneously a plurality of times during a sampling clock period at each of a plurality of phase rotator positions to generate a plurality of partial values, wherein subset pluralities of the partial values are associated to phase rotator positions. The partial values are combined into a global value which is analyzed to determine a quality of the high speed signal. Phase rotator behavior may also be analyzed to determine signal quality. A best position to lock a phase rotator when determining signal quality may be determined from a graphic characterization of a phase rotator position distribution.Type: GrantFiled: July 7, 2007Date of Patent: January 13, 2009Assignee: International Business Machines CorporationInventors: Alain Blanc, Patrick Jeanniot
