    摘要： A method and apparatus for improving a channel change response time are disclosed. A meta channel associated with an original and auxiliary media streams is generated. The information conveyed by the meta channel is propagated toward at least one user device. The user device may receive the meta channel information and select one of the media streams using the meta channel information in response to a channel change request from a user terminal, or a network device may select one of the media streams for a user terminal in response to a channel change request from the user terminal.

    摘要： The invention includes a method and apparatus for notification and delivery of messages to mobile users using a secure client associated with a user device. The secure client includes a power module, a communication module, a storage module, and an alert module. The power module powers the client device independent of a power state of the user device. The communication module receives a wake-up message and responsively triggers the secure client to switch from an inactive state to an active state without changing the power state of the user device, initiates a secure connection with a secure gateway in response to the wake-up message, and requests and receives a user message from a messaging application using the secure connection. The storage module stores the received message independent of the power state of the user device. The alert module activates an alert to indicate that the message is available.

    摘要： A method and apparatus for improved inter-domain routing convergence, include transmitting reason information associated with a route update or withdraw. An apparatus receiving the reason information associated with the update or withdraw uses the reason information to determine which of its candidate routes are also affected by substantially the same event that triggered the initial route update or withdraw and which of its candidate routes are not affected. For example, a candidate route may be considered to be transient if the apparatus receiving the reason information determines from the received reason information that a candidate route is going to be updated or withdrawn in the near future due. A candidate route considered as a transient route is avoided being advertised as a preferred route.

    摘要： A method and apparatus for providing link state routing protocol redundancy in a router. A router includes an active controller and at least one standby controller. An internal adjacency relationship is established between the active controller and the standby controller to enable automatic switchover upon disablement of said active controller. The adjacency relationship is established by mirroring configuration data on a standby controller from an active controller, synchronizing Hello information between the active and standby controllers, and synchronizing database information between the active and standby controllers.

    摘要： An arrangement having a service fiber and a protection fiber connected to different I/O modules that are connected to an ATM switch. The switching functions necessary for achieving protection are realized through cooperation between the CPUs on the I/O modules of the service and the protection lines and the ATM switch fabric. The line selected has its frame buffer open, while the line in the standby mode has its frame buffer closed. In the other direction, traffic is multi-cast onto both the service and the protection lines by the ATM processing unit. In this manner, the protection fiber always contains information, ready to be switched from standby mode into active mode.
