Abstract: The present invention relates to a method and apparatus for distributing paging messages in a wireless communication system. The wireless communication system may include a paging controller configured to distribute the paging messages in a paging area, a paging group including a plurality of base stations within the paging area configured to receive the paging message, and a paging interface between the paging controller and the paging group configured to support transmission of only the paging messages to all the plurality of base stations through a single transmission of the paging message from the paging controller. The method may include distributing a paging message to all of a plurality of base stations through a single transmission of a paging message from a paging controller over a secured IP-multicast group.

Abstract: A method and apparatus is described for encapsulating data from a cell and packet based network utilizing a virtual circuit type implementation mechanism and an asynchronous transfer format such as ATM in a frame of a frame based protocol such as Ethernet. At least two policies are provided for scheduling the encapsulation of the data. One of the at least two policies is selected for encapsulating the data.

Abstract: The present invention describes a method and system for achieving high availability in a networked computer system. In particular, the method for achieving high-availability is executed in a networked computer system. The networked computer system includes nodes connected by a network. The method includes using high-availability-aware components to represent hardware and software in the networked computer system, managing the components to achieve a desired level of redundancy, and monitoring health of the networked computer system, including health of components and nodes. The method further includes detecting a failure in the networked computer system. Failures detected by the method include failures of a component and/or node. Finally, the method includes recovering from the failure by performing an appropriate failure recovery procedure.

Abstract: A distributed computer system, including a group of nodes. Each of the nodes have a network operating system, enabling one-to-one messages and one-to-several messages between said nodes, a first function capable of marking a pending message as in error, a node failure storage function, and a second function. The second function being responsive to the node failure storage function indicating a given node as failing, for calling said first function to force marking selected messages to that given node into error, the selected messages include pending messages which satisfy a given condition.

Abstract: Locating nodes in a distributed computer system. The system comprises a switch having ports. The switch comprises agent code that is operable to report status of the ports and to identify a node coupled to the ports. The system also has a node coupled to the switch that has manager code. The manager code is operable to retrieve, from the switch, status of a port of the switch. The manager code is also operable to request, from the switch, an identifier of a node coupled to the port of the switch in response to status for the port meeting a condition. The manager code is further operable to maintain a table of data groups comprising port identifiers and identifiers of nodes coupled to the ports.
