Patent number: 6601988Abstract: Time values (hour, minute, AM/PM parameter) can be simply and quickly set in a computer system using a graphical representation of a circular analog clock face. Time setting zones (hour-indicative sectors and minute-indicative subsectors) are defined on the displayed clock face. A user selects an hour and a minute value in a single point-and-click operation by moving a cursor into the appropriate subsector within the appropriate sector and then performing a cursor select operation. Two different approaches are described for choosing an AM or a PM parameter to be associated with the selected time value.Type: GrantFiled: March 19, 2001Date of Patent: August 5, 2003Assignee: International Business Machines CorporationInventor: Mark E.

Patent number: 6583781Abstract: Methods, systems and computer program products are provide which control events associated with an element of a user interface by determining a characteristic(s) of pointer movement of a pointing device and adjusting a condition(s) for triggering an event associated with the element based on the determined characteristic of pointer movement. The triggering of the event is controlled utilizing the adjusted condition. By determining characteristics of pointer movement, a user's intent may be inferred from that pointer movement and, based on the inferred intent, the conditions for triggering of events may be adjusted consistent with such inferred intent.Type: GrantFiled: October 17, 2000Date of Patent: June 24, 2003Assignee: International Business Machines CorporationInventors: Niraj P.

Patent number: 6553421Abstract: A data communication network includes a network client, a network server, and a name caching entity located between the network client and the network server. The network server is coupled to the data communication network by a plurality of network adapters that each have a different network (e.g., Media Access Control (MAC)) address, but share a common logical name. The name caching entity includes a name cache, which stores the common logical name shared by the server's network adapters in association with the network address of one of the network adapters. By reference to the name cache, the name caching entity is able to convert broadcast frames to unicast frames, thereby advantageously reducing broadcast frames in the network.Type: GrantFiled: September 15, 1998Date of Patent: April 22, 2003Assignee: International Business Machines CorporationInventors: John Kevin Frick, Daniel Dean Heimsoth, Jon Michael Houghton, Edward Joel Rovner

Patent number: 6538990Abstract: A Fast Ethernet LAN hub may include a plurality of 100 Mbps ports, each dedicated to a single station or shared with a high speed Ethernet segment. The ports on the Fast Ethernet hub are connected to a low speed 10 Mbps LAN segment through a high speed LAN/low speed LAN bridge port. Because of the mismatch in data transmission rates, the LAN bridge may experience congestion as a result of data flow at the high speed/low speed interface. To minimize the impact on high speed ports, a congestion control system responds to a congested state by identifying 100 Mbps ports currently actively communicating with remote stations through the 10 Mbps port. Any 100 Mbps port identified as supporting a current connection to a network management station is excluded from the set of identified ports. The identified ports are temporarily prevented from sending or receiving data. Other 100 Mbps ports on the hub remain unaffected by the congestion control action.Type: GrantFiled: April 15, 1999Date of Patent: March 25, 2003Assignee: International Business Machines CorporationInventor: Thomas Joseph Prorock

Patent number: 6512742Abstract: A method and system are disclosed for balanced transmitting of data across a link aggregation of k links in a network, where k is not a power of 2, where data is specified by frames each having a source address and a destination address. N bits of the source address and N bits of the destination address are determined to be XORed together where N is greater than 2. An index table with 2N entry positions is created where each of the entry positions is assigned an index number between 0 and 2N−1. The entry positions of the index table are filled with one link of the k links in each entry position by repetitively entering each of the k links until all of the entry positions are filled. The frames of data with identical source address and destination addresses as other frames of data are grouped into a flow. N bits of the source address are XORed together with N bits of the destination address for each flow to obtain an N bit index number for each flow.Type: GrantFiled: December 9, 1998Date of Patent: January 28, 2003Assignee: International Business Machines CorporationInventors: Cedell Adam Alexander, Jr., Arush Kumar, Loren Douglas Larsen

Patent number: 6452921Abstract: In a data communication internetwork including a source station, an end station, and a default router for the source station, a default communication path including the default router is defined between the source station and the destination station. During operation of the data communication internetwork, a shortcut data communication path by passing the default router is established between the source station and the destination station, such that data packets transmitted by the source station are not received by the default router. After the shortcut communication path has been established, a control frame containing source-route information regarding the source station is transmitted to the router, and the source-route information is stored at the router.Type: GrantFiled: November 24, 1998Date of Patent: September 17, 2002Assignee: International Business Machines CorporationInventors: Cedell Adam Alexander, Jr., Russell Eugene Gardo, Brahmanand Kumar Gorti, Olen Lee Stokes, Jr.

Patent number: 6330560Abstract: A system and method for a multiple manager to multiple server Internet Protocol (IP) locking application in a directory-enabled network. The IP locking application is a component of a network management application and runs on each server device. The IP locking application processes requests from a network management application on two user-defined TCP/IP port numbers. The first port is designated as the status port and can be accessed by multiple network management applications and/or multiple users to determine the identification of the network management application and/or user that has control of the second port which is designated as the lock port. The status port is used to determine whether or not the server directory is currently being updated by another network management application or user. The lock port is used to actually lock the server device by forming a connection to the port and passing the user and network management application identifiers of the lock requester.Type: GrantFiled: September 10, 1999Date of Patent: December 11, 2001Assignee: International Business Machines CorporationInventors: Bret Elliott Harrison, William Donald Reed, Leo Temoshenko

Patent number: 6226297Abstract: A method for providing redundancy to an Asynchronous Transfer Mode (ATM) emulated local-area network (LAN) is disclosed. The ATM emulated LAN is served by a primary LAN Emulation Server, a Broadcast and Unknown Server (LES/BUS), and a LAN Emulation Configuration Server (LECS). A backup LES/BUS is coupled to the ATM emulated LAN. A logical redundancy virtual channel connection (VCC) is then established between the primary LES/BUS and the backup LES/BUS. When the redundancy VCC is present between the primary LES/BUS and the backup LES/BUS, the backup LES/BUS is placed in a dormant mode. However, when the redundancy VCC is absence between the primary LES/BUS and the backup LES/BUS, the backup LES/BUS is activated to serve any request generated by the ATM emulated LAN.Type: GrantFiled: January 30, 1998Date of Patent: May 1, 2001Assignee: International Business Machines CorporationInventors: Cedell A.
