Publication number: 20020131365Abstract: The decision to discard or forward a packet is made by a flow control mechanism, upstream from the forwarding engine in the node of a communication network. The forwarding engine includes a switch with mechanism to detect congestion in the switch and return a binary signal B indicating congestion or no congestion. The flow control mechanism uses B and other network related information to generate a probability transmission table against which received packets are tested to determine proactively whether a packet is to be discarded or forwarded.Type: ApplicationFiled: January 18, 2001Publication date: September 19, 2002Applicant: International Business Machines CorporationInventors: Kenneth James Barker, Gordon Taylor Davis, Clark Debs Jeffries, Mark Anthony Rinaldi, Kartik Sudeep

Patent number: 6381267Abstract: Modems, methods, and computer program products for falling back to a low speed mode of operation upon detection of abnormal line conditions during startup perform a first phase of a multiphase startup procedure in accordance with a high speed mode of operation. A determination is then made whether the line conditions will support high speed communication. If a high speed connection cannot be established, then subsequent phases of the startup procedure will be performed in accordance with the low speed mode of operation. Otherwise, subsequent phases of the startup procedure will be performed in accordance with the high speed mode of operation.Type: GrantFiled: March 8, 1999Date of Patent: April 30, 2002Assignee: International Business Machines CorporationInventors: Youssef Abdelilah, Gordon Taylor Davis, Jeffrey Haskell Derby, Ajay Dholakia, Evangelos Stavros Eleftheriou, Dongming Hwang, Fredy D.

Patent number: 6341360Abstract: Decision feedback equalizers having a stabilization capability, and methods and computer program products for stabilizing a decision feedback equalizer under severe error conditions use output samples from an equalizer to determine whether a severe error event has occurred in accordance with predefined criteria. If a severe error occurs, then a determination is made to evaluate whether the number of severe errors that have occurred has exceeded a threshold. If the threshold has been exceeded, then the coefficients for the filter(s) in the decision feedback equalizer are preserved in their current state. Severe errors can cause the equalizer filter coefficients to be pulled away from their normal operating values, which can result in several modulation cycles passing before the coefficients are restored.Type: GrantFiled: March 8, 1999Date of Patent: January 22, 2002Assignee: International Business Machines CorporationInventors: Youssef Abdelilah, Gordon Taylor Davis, Jeffrey Haskell Derby, Ajay Dholakia, Evangelos Stavros Eleftheriou, Dongming Hwang, Fredy D.

Patent number: 6065082Abstract: Communication, using a synchronous protocol, over a synchronous communications link, between synchronous application programs executed on a terminal (i.e., personal computer, PC) with an asynchronous byte-oriented interface and a PC with a synchronous frame orientated interface is made possible by enhancing the PC with the asynchronous byte-oriented interface with a device which modifies the data to be transmitted by inserting framing flags and transparency characters before the data passes through the COMM port (asynchronous byte-oriented interface) and extracting the transparency characters after the data exits the COMM port. As a consequence, the PC with the frame-oriented interface does not have to be modified.Type: GrantFiled: November 13, 1998Date of Patent: May 16, 2000Assignee: International Business Machines CorporationInventors: Dana Lynn Blair, Gordon Taylor Davis, Cloyd Stanley McIlvaine

Patent number: 5831837Abstract: A switch mode power supply comprises: a transformer (T1). A switch (Q4) alternately opens and closes a current path through a primary winding (L1) of the transformer in response to a pulse switching signal. An oscillator (110) generates the switching signal and synchronises the switching signal to a synchronisation signal (HSYNC') from an external source. A pulse width modulator (140) varies the pulse width of the switching signal in dependence upon a feedback signal indicative of a load on the power supply. A current limiter (150) turns off the switch to close the current path in response to current in the primary winding exceeding a threshold. Compensation means (160) is provided for varying the threshold in dependence upon the frequency of the synchronisation signal.Type: GrantFiled: June 9, 1997Date of Patent: November 3, 1998Assignee: International Business Machines CorporationInventors: David Coyne, David Alexander Grant, Ewan James Lister, Lindsay Gordon Taylor

Patent number: 5668957Abstract: Apparatus and method for providing virtual DMA capability for an adapter card connected to a host system bus with no DMA support. A special interface circuit resides on an adapter card together with a cache data memory. A special software driver resides in the host system. The software driver manages DMA transfers for the application processing circuitry on the adapter card using the cache data memory. The processing circuitry on the adapter card transfers data in and out of the cache data memory as if it had direct memory access to host system memory. In this way, an adapter card for a non-DMA-capable bus, such as the personal computer memory card international association (PCMCIA) bus can act as a bus master.Type: GrantFiled: November 2, 1995Date of Patent: September 16, 1997Assignee: International Business Machines CorporationInventors: Gordon Taylor Davis, Robert James Devins, Patrick Kwong-hung Kam, James L.
