Abstract: A system and method for providing session admission control are provided. Generally, a source of a communication request and a session director are utilized. The session director allocates bandwidth to accommodate a bandwidth allocation request from the source, ensures that quantity of the allocated bandwidth is appropriate for transmission of multimedia packets from the source to the session director, and ensures that quality of service of the allocated bandwidth is appropriate to provide a flow of the multimedia packets via the allocated bandwidth.

Abstract: Methods and systems for controlling access to a host processor is disclosed. One exemplary method comprises the steps of receiving a plurality of signaling packets and controlling access to a host processor, via a first and a second path, for at least a portion of the packets in accordance with a bandwidth limit for the respective path. An exemplary system comprises: a host processor; and a traffic manager coupled to the host processor via a first path and a second path. The traffic manager is configured to communicate at least a portion of the packets to the host processor via a selected one of the paths. The traffic manager is further configured to regulate traffic along the first path such that the bandwidth limit of the first path is respected, and to regulate traffic along the second path such that the bandwidth limit of the second path is respected.

Abstract: A system and method for providing statistics gathering within a packet network is disclosed. The system comprises a network processor, a traffic manager, a host processor, and a field programmable gate array. The network processor adds a header to received multimedia packets and the traffic manager measures and enforces multimedia flow rates. The host processor performs multimedia flow quality measurement services on a per flow basis, wherein the multimedia flow quality measurement services comprise maintaining current statistics for multimedia flows within the network processor including aggregate and minimum/maximum statistics for the multimedia flow.

Abstract: A system and method for determining a source of an Internet protocol packet (IP). Generally, the system comprises a memory and a processor. The processor compares a destination address of the IP packet to a first destination address stored within a first destination address cell of the memory, and compares a destination port of the IP packet to a first destination port stored within a first destination port cell of the memory. The network processor also compares a source address of the IP packet to a first source address stored within a first source address cell of the memory, and compares a source port of the IP packet to a first source port stored within a first source port cell of the memory, wherein the stored first source address and the stored first source port are associated with the stored first destination address and the stored first destination port.

Abstract: A system and method that implements a network of voice mail systems using a telephone network. Each node of the network queues voice messages to be sent to remote locations in a voice mailbox created for that remote location until a scheduled time for sending messages to that remote location. When the messages are sent, conventional telephone lines of the telephone network are used by dialing through the public telephone network to establish a node to node connection. When the connection is established, the messages in the queue are transferred over the telephone network in either analog or digital form. Multiple message processors in each node can allow multiple connections and simultaneous transmission and receipt of messages between nodes.
