Managing multi-media call flows involves establishing a call in an environment having a first signaling protocol to an environment having a second signaling protocol, identifying in the first signaling protocol that the call is going to the environment having the second signaling protocol, replacing a first signaling element of the first signaling protocol with a corresponding second signal element of the second protocol, and completing the call on the basis of the first signaling protocol with the corresponding second signaling element of the second protocol.

ATM-coupled multicast data are transmitted to a multiplicity of ATM users over an IP backbone by having a controller in the IP backbone translate a pre-stored Multicast Initiating Address into a multiplicity of pre-stored pairs of addresses, each pair composed of a users ATM destination address and the IP address of the (user) gateway serving the users ATM destination, then establishing connections between the multicast source ATM address and each of the users ATM addresses, having IP routers attach the user gateways to the multicast group, and encapsulating the multicast data ATM cells in IP packets for routing to the user gateways, and decapsulating the multicast data ATM cells for routing to the user ATM addresses.

The invention comprises a system and method for transmitting and receiving VoDSL voice traffic that avoids, where possible, the transcoding of a speech signal multiple times. The invention advantageously provides enhanced Quality of Service (QoS) by opportunistically avoiding signal degradation where VoDSL to VoDSL gateway communications may be provided.

A method and apparatus for transporting Asynchronous Transfer Mode protocol cells over an Internet Protocol backbone network is disclosed herein. ATM signaling cells are initially received at a source gateway interconnected to the IP backbone. The signaling message is converted to an H. 323 message and transmitted to a controller which provides ATM to IP address translation. The corresponding IP address is received at the source gateway and ATM bearer cells of the same call as the original ATM signaling cell are encapsulated with IP headers which include the IP address to form an IP packet which keeps the ATM cells intact within the packet. The IP packet is transferred onto the IP backbone network and routed to the appropriate destination gateway where the IP packets are decapsulated to retrieve the original ATM bearer cell.

A simplified methodology for accomplishing traffic management in a packet based network is achieved by allowing allocation of bandwidth based on a count of the number of endpoint connections associated with a specific service for a corresponding network device. A network device (e. g. , IP router) can be configured to count the number of TCP/IP and UDP/IP connections and bandwidth usage per interface. The counting can be done by identifying the IP Addresses, Type of Service (TOS), and TCP/UDP and/or UDP/IP socket number range in the IP Header of a packet and then querying a specific communication type. When reaching the maximum allowed connections or bandwidth for a specific service, the network device (e. g. , IP router) stops forwarding any new calls by means of dropping packets of new calls and informing the given endpoints to disconnect the new calls. In one exemplary embodiment of the invention, a procedure for managing traffic flowing through individual routers of a packet network includes the steps of reserving a given amount of bandwidth on interfaces of the individual routers for specific types of communications traffic, periodically querying endpoint connections based on data from a corresponding router connection table, receiving responses from the periodic querying to determine a current connection status and bandwidth allocation of said endpoints and calculating current bandwidth allocation for a specific type communications service on an interface handled by the router.

The invention comprises a system and method for transmitting and receiving multiplexed Voice over Internet Protocol (VoIP) traffic. The invention advantageously provides efficient gateway-to-gateway communication by reducing overhead where at least two conversations are transmitted between VoIP gateways. Additionally, signal degradation is avoided since there is no transcoding of signals.

A system and method is provided for transmitting a packet received at a Foreign Agent associated with a Packet Data Service Node where the packet has a source network layer address, such as an Internet Protocol address of a mobile station that points to a geographically remote Home Agent and a destination Internet Protocol address. The method comprises caching Internet Protocol addresses in memory, comparing the destination Internet Protocol address of the received packet with the Internet Protocol addresses in memory, and if no match is found, querying a Policy Server for a match, and forwarding the received packet with the Internet Protocol address of the Foreign Agent associated with the Packet Data Service Node as the source Internet Protocol address when the destination address of the received packet matches the Internet Protocol address in memory or Policy Server, resulting in significant savings in transport cost and response time.
