Abstract: A system, method, and computer program product through which address resolution is performed for nodes (101, 103) of a network that are behind a network address translator (NAT). A determination is made upon the initiation of a communication session as to whether one or more of the nodes (101, 103) included in the session are behind a NAT. Based on the determination, information is exchanged (L102, L103) from an independent application server (105) to the nodes (101, 103) included in the session so as to resolve the addressing problems introduced by the NAT. The invention is applicable in applications including, but not limited to, IP telephony, and applications complying with the session initiation protocol (SIP).

Abstract: A method and system for monitoring the statuses of components within a telephony system, especially a cable-based telephony system, and to monitor quality issues within such system. By determining how components with the system are behaving, a network administrator may be able to troubleshoot problems remotely using a known set of problem resolution techniques. Such techniques may be applied stepwise by the administrator or may be automated through computer intervention.

Abstract: A computer based system, computer program product, and method for managing network status message data flow are provided for managing the flow rate of network status messages to a remote network operations console. Detailed network status is abstracted into hierarchical levels of detail so that an appropriate level of detail can be provided from a flow control daemon to the requesting network operations console without exceeding a predetermined allocation of bandwidth set aside for network status reporting.
