Abstract: A multicast transmission gating system is provided as a gateway for reception of multicast transmissions for various multicast groups from a public network to a private network having a number of clients. The gating system provides transcoding capability to provide real-time sub-groups to the private network and provides control of access by network clients to prevent bandwidth conflicts and dissemination of secure information. Firewall capabilities are also supported to prevent security breaches of the private network via the multicast facilities of the public network.

Abstract: Extending network capabilities for a network with a policy-based network management (PBNM) architecture. The method includes sending a first message from a policy enforcement point (PEP) to a policy decision point (PDP) in response to an external action, and sending a Java object in a second message from the PDP to the PEP in response to receiving the first message. The Java object may be executed on the PEP to implement a policy.

Abstract: A method and system analyze traffic on a network by monitoring network traffic and, when a particular network condition (for example, network congestion) is detected, gathering information about the traffic on the network by launching an agent and having the agent iteratively identify which of the links on the node on which the agent operates accepts a type or class of traffic, traverse the identified link to the node across the link, and repeat the process.

Abstract: A system and method of data transmission in a wireless communication network are disclosed. The method comprises detecting an error in an original transmission and in response thereto, determining that latency sensitive data in the original transmission would be stale when transmitting a copy of the original transmission. The method further comprises transmitting the copy of the original transmission when a retransmission value function at least equals a predetermined threshold and transmitting a new transmission when the retransmission value function is less than the predetermined threshold. The new transmission comprises a copy of the data from the original transmission that is not stale when transmitting the new transmission.

Abstract: A method for communicating between a sender and a receiver a set of dependencies among a set of media streams in a data network. The method comprises the step of creating a payload data packet having a header and a set of stream descriptors, where the header has a required stream field. Each stream descriptor is uniquely associated with a media stream belonging to the set of media streams and has a connection field to provide a network address for its associated media stream. Each stream descriptor that is associated with a media stream having a dependency also has a dependency field. The method also comprises the steps of creating a control data packet having the payload data packet as a payload; setting the required stream field to a value indicative of a required set of media streams, the required set of media streams being a subset of the set of media streams; and setting the dependency fields to indicate the set of relationships.
