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.

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.

The invention includes a method and apparatus for providing secure remote access to enterprise networks. An apparatus includes a network interface module adapted for maintaining a secure network connection with a network device independent of a power state of a host computer associated with the apparatus a storage module for storing information associated with the secure connection, and a processor coupled to the network interface and the memory where the processor is adapted for automatically initiating the secure connection without user interaction.

For use with a path vector routing protocol, a system and method for increasing alternative network route convergence speed and a border gateway router incorporating the system or the method. In one embodiment, the system includes: (1) a router information base (RIB) data receiver, associated with a network, that receives RIB data including: (1a) an update of an active route to a domain in the network that causes the active route to become a withdrawn route and (1b) indications, based on loopback addresses associated with nodes through which the withdrawn route passed, of a reachability of the each of the nodes and (2) route disqualification logic, associated with the RIB data receiver, that disqualifies alternative routes to the domain based on the indications.

Congestion in connection-oriented data networks is alleviated by simulating the rerouting of circuits to uncongested parts of the network and then rerouting such circuits in a manner that causes little, or no, disruption to other parts of the network.

A system and method providing fault resilient multicast services using a network topology in which a source node communicates with a plurality of receiver nodes via at least two disjoint paths in which at least one receiver node is provisioned according to a 1+1 protection mechanism.

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.

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.
