  • Patent number: 7292571
    Abstract: Generally, a terminal can access a resource selection device to access a content source, the content source being structured and arranged to respond directly to the terminal. For example, a PC (“personal computer”) may be pointed at a load-balancing switch. The load balancing switch translates the PC's traffic and directs the PC traffic to a server (or switch) providing streaming services. The server responds directly to the terminal, but uses the IP address/identity of the load-balancing switch with which the terminal is communicating.

  • Patent number: 7289511
    Abstract: A system and method provide enhanced services for a call that is transported from a communication device through an asynchronous transfer mode system. The call has user communications in asynchronous transfer mode cells and call signaling. A signaling processor receives the call signaling and processes the call signaling to determine a connection to a service platform. The signaling processor transports a processor control message designating the selected connection. An asynchronous transfer mode interworking unit receives the user communications from the communication device and the processor control message from the signaling processor. The asynchronous transfer mode interworking unit converts the user communications from the asynchronous transfer mode cells to a format compatible with the service platform and dynamically transports the user communications to the service platform in real time. The service platform processes the user communications.

  • Patent number: 7283476
    Abstract: A switch to switch protocol for network load balancing which negotiates among switches operable in accordance with the invention to assign a unique loop bit offset identifier value to each switch. Various other load balancing protocols associated with the switches then utilize the loop bit offset value as an identifier field when determining loops in the network of switches and costs associated with non-looped paths in the switches. A loop bit offset identifier requires less switch processing overhead than techniques which utilize an entire address value (i.e., MAC address value) for such protocols. Further, the loop bit offset identifier assigned by the present invention reduces the size of load balancing related packets. Specifically, cost computation related packets are reduced in size to the minimum 64 byte packet size through use of the loop bit offset identifier value of the present invention.

  • Patent number: 7272145
    Abstract: A system and method establish an Internet protocol (IP) connection between an originating end-system and a destination end-system, incapable of resource reservation protocol (RSVP) signaling, through a switched transport network. A first interworking function (IWF) device inserts its switched transport network address into a first data field of an RSVP path message, received from an RSVP capable proxy signaling device that interfaces with the destination end-system. The first IWF device forwards the path message, through routers in an IP network, which is passed without modification to the first data field. A second IWF device receives the path message and forwards a setup message to the first IWF device through switching devices in the switched transport network, based on the first IWF device's address retrieved from the first data field of the path message. The IP connection is established through the proxy signaling device in response to the setup message.

  • Patent number: 7272143
    Abstract: An ATM communication system has a connection setting section for controlling a plurality of ATM switches to set an n:n bidirectional ATM connection having n terminals of a plurality of constituent terminals as terminal points and using the VPI/VCI for identifying the n terminal points, and a process ID allocating section for allocating an MID as a process ID to a plurality of processes, executed by the n terminals for sending a message to the bidirectional ATM connection. The ATM communication system migrates a process executed on an arbitrary terminal to another terminal while keeping the process ID allocated to the processes. Where a dead-lock occurs due to that a process becomes a sleep state for the reason of that the bandwidth of a physical link is insufficient for executing in parallel the processes on the ATM communication system, the bandwidth of the physical link that a sleeping process occupies is intercepted to avoid a CAC dead-lock.

  • Patent number: 7127399
    Abstract: In a voice communication system 1, a gateway server 4 receives IP packets from the Internet, converts PCM voice data in the IP packets into AMR encoded voice data frames, and transmits to a mobile terminal 7. During the propagation to the gateway server 4, there is a possibility of loss of IP packets and crucial bit error in IP packets. In that case, the gateway server 4 puts “No data” data on frames as voice encoded data for the IP packets in question and sends it to the mobile terminal 7. The “No data” data is a target of concealment.
