  • Patent number: 7318119
    Abstract: A fault-tolerant and efficient way of deducing a set of inconsistent stripes for a network RAID protocol, wherein clients forward input/output (I/O) to a particular controller device called the coordinator, which executes RAID logic and which sends out device IOs to the relevant storage devices. If the coordinator fails then a new coordinator reconstructs its state from the storage devices.

  • Patent number: 7240155
    Abstract: A client node of a distributed storage system adaptive determines on an operation-by-operation basis whether to process a network-RAID IO operation (IO request) locally at the client node or to forward the IO request to a storage server of the system for processing. The client node determines to process the requested network-RAID operation at the client node when a local estimator for a type of the requested network-RAID operation is less than a central estimator for the type of the requested network-RAID operation. Otherwise, the client node determines to process the requested network-RAID operation at a storage server when the local estimator for the type of the requested network-RAID operation is greater than the central estimator for the type of the requested network-RAID operation.

  • Publication number: 20060084431
    Abstract: A technique and system are provided to allow home subscriber servers (HSSs) to retrieve a subscriber's dynamic location/state information from a legacy home location register (HLR). For example, a mobile application part (MAP) operation ATI (AnyTimeInterrogation) messaging technique may be used by the home subscriber server (HSS) to query the legacy home location register (HLR) and obtain the requested location/state information.

  • Publication number: 20060067338
    Abstract: A routing technique for supporting an internet protocol (IP) Multimedia Subsystem (IMS) Subscriber Locator Function (SLF) is provided. It is, in part, based on using a user's identification information, e.g. a user's realm, to facilitate the routing of information. This technique enables the implementation of a distributed subscriber location function (SLF) in an IMS network. The subscriber locator function (SLF) ultimately allows for accommodation of more users through multiple home subscriber service (HSS) elements.

  • Publication number: 20050113096
    Abstract: This invention relates to a method and apparatus for anonymous call redirection in a wireless network. More particularly, the invention is directed to providing an anonymous call redirection service for wireless service subscribers by implementing service logic within the wireless network to intercept incoming calls for which no calling name or number is available and redirect the calls to an intelligent peripheral device for further processing. In one embodiment, anonymous calls are directed to an intelligent peripheral such as a network-based recording device, which records the caller's name and then repeats or plays this name to the called party, before the call is connected to allow the called party to accept or reject the call.

  • Patent number: 5988113
    Abstract: A self-activated acaricide applicator for killing ticks on large mammals. The applicator is self-activated by motion and heat detection when the mammal moves to investigate an attractant canister. This results in the discharge of an atomized acaricide onto the mammal.
