Patent number: 9042302Abstract: Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. These services may include caching of data, data or video compression techniques, push-based services, charging, application serving, analytics, security, data filtering, and new revenue-producing services, as well as others. This architecture allows performing new mobile network services at the edge of a mobile data network within the infrastructure of an existing mobile data network.Type: GrantFiled: November 15, 2012Date of Patent: May 26, 2015Assignee: International Business Machines CorporationInventors: Bruce O. Anthony, Jr., Ronald L. Billau, Canio Cillis, Vincenzo V. Di Luoffo, Philip E. Grady, Ravinder K. Sabhikhi, Raj K. Singh, George W. Van Leeuwen

Patent number: 9001718Abstract: Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A breakout component in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. These services may require the use of keys. Keys are stored and retrieved from a non-volatile key storage in a way that assures subsystems that need the keys have access to the keys. The keys retrieved from the non-volatile key storage are stored in a shared memory in the requesting subsystem, which allows any applications that requires access to the keys to directly access the keys in the shared memory.Type: GrantFiled: November 19, 2012Date of Patent: April 7, 2015Assignee: International Business Machines CorporationInventors: Ronald L. Billau, Vincenzo V. Di Luoffo, Philip E. Grady, George W. Van Leeuwen

Patent number: 8724455Abstract: A fail-to-wire (FTW) module preserves a primary data path connection from an upstream computer to a downstream computer if there is any kind of failure in a breakout data path to a breakout system. The FTW module provides switches between the incoming data network data and the breakout system such that when the breakout system encounters a failure, the switches are de-activated to bypass the breakout system. The switches in the FTW module are activated by a system health signal controlled by a health monitor in the breakout system. The health monitor provides intelligent switch control based on alerts from a variety of control points. These control points include firmware, hardware, thermal sensors, subsystem operating systems, subsystem software applications, and appliance tamper logic in order to determine if the FTW module switches should be in an active or inactive state.Type: GrantFiled: January 20, 2012Date of Patent: May 13, 2014Assignee: International Business Machines CorporationInventors: William F. Berg, Jeremiah D. Carlin, Scott A. Liebl, George W. Van Leeuwen

The switches in the FTW module are activated by a system health signal from the breakout system. The breakout system can be serviced without interrupting the data network connections since the FTW module can be extracted from the failed breakout system with data network connections intact. The FTW module is preferably a compact modular element that fits within the breakout chassis and is easily inserted and removed from the breakout system during servicing operations.Type: GrantFiled: November 16, 2011Date of Patent: May 6, 2014Assignee: International Business Machines CorporationInventors: Raymond F.

Patent number: 5630104Abstract: A disk drive stores multimedia data in long spiral data tracks. The tracks on opposite surfaces of the disk spiral in opposite directions, so that a track on one surface can be read as the actuator sweeps in, and a track on the opposite surface can be read as the actuator sweeps out. Because the actuator only follows spiral tracks without performing long seek operations, the actuator motor can be reduced in size and stresses on actuator bearings and other parts are reduced. Additionally, due to reduced disturbances associated with seeks, it is possible to follow tracks more closely and therefore reduce the width of individual tracks. Further cost reductions are accomplished by spinning the disks at a slower speed and reducing the size of the spin motor accordingly. Finally, data density can be increased simply because multimedia data does not require the same low error rate as conventional data. Preferably, a group of disk drives optimized for multimedia data is used to form a video-on-demand system.Type: GrantFiled: May 18, 1995Date of Patent: May 13, 1997Assignee: International Business Machines CorporationInventors: Hal H.
