摘要： In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established. Each client terminal uses that MARS server, whether on the same or different IP sub-networks, but on a common ATM network, for purposes of mapping the multicast IP addresses used in the conference into a set of unicast ATM endpoint addresses used by the ATM-connected client terminals. Similarly, when a specific conference uses a Multicast Server, a single special purpose Multicast Server is used for all clients on the conference, whether on the same or different IP sub-networks, for purposes of establishing point-to-multipoint ATM connections to the conference endpoints.

摘要： In a multicast capable IP network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. When a conference originator establishes the conference, a number of multicast IP addresses are allocated for later assignment to the clients during the conference. As each client joins the conference, it is assigned a multicast IP address from the allocated group for each media type it will transmit. Those assigned addresses are then marked as unavailable for assignment to any other client that subsequently joins the conference. When the original client later exits the conference, its assigned multicast IP address(es) is (are) marked as available for assignment to a later joining client. At the conclusion of the conference, all multicast IP addresses allocated to the conference are marked as available for use in another conference.

摘要： This invention provides a more effective method for capacity planning and traffic engineering of packet networks that connect Virtual Private Network (VPN) sites. A distributed architecture efficiently computes traffic matrixes that show the number of bytes and/or packets exchanged among provider edge (PE) routers and/or service nodes. Each PE router in a service node is exports flow records to a Flow Record Processor (FRP) in the same location. The FRPs use these records in conjunction with configuration data extracted from the PE routers to compute partial traffic matrixes. The partial traffic matrixes are uploaded to a Matrix Generator to create a total traffic matrix. The total traffic matrix is essential input for capacity planning or traffic engineering tools.

摘要： A method of configuring a network element such that a Virtual Private Network (VPN) site can connect to the network element is disclosed. An interface on a Provider Edge (PE) router is configured in restricted mode. A request is received from the interface to authenticate a user associated with a VPN requesting to connect to the interface. A determination is made as to whether the user is authorized to submit requests to the interface. If the user is authorized, an activation request is received from the interface to allow the VPN can connect to the interface. A determination is made as to whether the user is authorized to connect to the interface via the VPN. If the user is authorized, VPN site parameters are configured at the PE router and the PE router is configured in unrestricted mode.

摘要： Systems in the current art provide capacity planning for packet networks. These systems require input data that characterizes traffic demands. The demands may be expressed as matrixes that record the number of bytes and packets exchanged between access routers or service nodes for each type-of-service. This invention defines a system and method to calculate these traffic matrixes. Access routers in a service node export flow records to a Record Collector. The flow records are processed to create ingress and egress records that are stored on the Record Collector. This data is uploaded to a Capacity Planning Server at which the traffic matrixes are generated. The egress access router(s) for a flow are determined by searching for matching ingress and egress records. Matching records have identical source and destination addresses. This algorithm requires no knowledge of the complex topology and routing protocols that are used within packet networks. Sampled or non-sampled flow records may be used. The concepts in this invention may also be used to calculate traffic matrixes for virtual private networks (VPNs).
