  • Patent number: 7406634
    Abstract: A method and apparatus utilizes an exception handler to implement LOAD and STORE instructions for moving data between a peripheral device and CPU registers. TLB entries for peripheral devices are flagged invalid during initialization and an exception handler occurs when LOAD or STORE instructions are executed by the CPU. The exception handler programs a data mover to perform the LOAD or STORE instruction so that the CPU will not hang up in the event that the peripheral device does not respond thereby avoiding reset of the SOC by the watchdog timer. If the peripheral device does not respond before an exception handler timer expires an error is indicated by the exception handler.

  • Patent number: 7386632
    Abstract: A method for maintaining Quality of Service for communication network subscribers regardless of their log-on location is disclosed. For one embodiment the communications network has a first access point having a first router and a local memory containing at least one user profile containing a subscriber's pool identifier, and a second access point having a second router configured to provide a forwarding rate based on a source address from each of said packets. A service type for a subscriber is defined. A pool identifier corresponding to a service level agreement is assigned to the subscriber. If the subscriber attempts to log-on to the second access point, the subscriber's pool identifier is obtained from a global memory available to the second access point. The pool identifier is used to select a source address. A packet sent by the subscriber is forwarded using the second router, each packet containing the source address.

  • Patent number: 7245614
    Abstract: A system for managing access to IP multicast traffic includes a join request manager within an access router. The access router includes a central processing unit (CPU) and a memory unit. The access router replicates multicast traffic flows for communication to one or more user devices within user systems coupled to the access router using a link. The join request manager receives a request to receive a multicast traffic flow, the request being received from one of the user devices within one of the user systems, and denies the request if a system metric is above a threshold.

  • Patent number: 7165117
    Abstract: An address is allocated to a host device which is selected to obtain network access from any access point within a given communications system, while maintaining a network bandwidth management scheme that is consistently applied to a user's network bandwidth usage regardless of the access point used by the user. This is accomplished using a communications network having a at least one access point coupled to a first router which is configured to forward packets at a forwarding rate based on a source address contained in each of the packets. A user profile is assigned to each subscriber belonging to an access point. Each user profile includes a pool identifier which corresponds to a forwarding rate used by the router for packets corresponding to the subscriber.

  • Publication number: 20060217105
    Abstract: Apparatuses and methods for a wireless device to provide location data of the wireless device and multimedia data in an emergency situation. The wireless device may initiate a communication link to an emergency response entity (e.g., service center or emergency service provider), and communicate with the emergency response entity over the communication link to provide location data of the wireless device and multimedia data associated therewith. The location data and the multimedia data, including audio, video, and textual information, may be transmitted to the emergency entity in a single message. In some embodiments, the initiation of the communication link may be accomplished by a single user entry to the wireless device.

  • Publication number: 20050193158
    Abstract: A bridging device has at least two ports. The first port allows the device to communicate with devices on an expansion bus and at least one other port to allow the bridge to communicate with a system memory on a system bus or other devices on another expansion bus. The device is capable of identifying at least two regions in memory, a descriptor region and a data region. A descriptor provides information about segments of data in the data region. The bridge may detect descriptors read from the memory, extract information related to data associated with those descriptors and use this information to perform prefetching of data from the system memory.

  • Patent number: 6895434
    Abstract: A method for handling access requests at multiple PoPs using the sharing of NAS information between the PoPs, enabling each PoP to maintain its own, independent, database of user records. When an access request is received, it is forwarded to a specific PoP designated as the user's “home PoP”. This home PoP is the only PoP to contain the user's records. The home PoP may then handle the access request by utilizing a local NAS list, the local NAS list being synchronized with other NAS lists in the network and providing information on all the “known” NASes throughout the entire network. This allows for a user to roam between PoPs, while reducing the bandwidth and security concerns that have existed in the past when users chose to roam. The NAS lists may then be updated via a central Network Control Console.

  • Patent number: 6871224
    Abstract: A method for conveying data communications network management information to an umbrella management system whereby network management information events are published on an information bus and received at a subscribing monitor interface located on the information bus. The monitor interface then converts the network management information events into umbrella management system-useable information and communicates the umbrella management useable information to the umbrella management system. In this manner, the umbrella management system is able to import valuable information pertaining to the devices and services that comprise the overall network. The monitor interface includes an adapter located on the information bus that subscribes to network management information events, a converter that formats the network management information events into data useable by the umbrella management system, and a forwarder that communicates the umbrella management system-useable data to the umbrella management system.
