  • Publication number: 20060187927
    Abstract: A system and method for providing rapid rerouting of real-time transport protocol (RTP) multi-media flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor configured by the software. The processor is configured to perform the steps of, performing flow processing on a data packet received at a first endpoint, from a second endpoint, removing a multi-protocol label switching (MPLS) tag from the data packet, translating a source address and destination address of the data packet, and determining a forwarding destination if more than one destination address of the data packet is provided.

  • Publication number: 20060098577
    Abstract: A system for assisting in controlling real-time transport protocol flow through multiple networks is disclosed The system utilizes at least a first computer and a second computer that is connected to the first computer, wherein the second computer comprises a second transceiver, a second memory having logic stored therein defining functions to be performed by the second computer, and a second processor The second processor is configured by the second memory to perform the functions of: performing an inbound screen on route information received by the second computer, from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined with the second computer; and performing an outbound screen on the received and screened information prior to transmitting the received and screened information.

  • Patent number: 6697475
    Abstract: An operating system independent distributed self-contained dynamic logic system is disclosed. The dynamic logic system enables EO functionality in small edge routers or programmable switches which serve a small population of users instead of the rather large population typically served by a 5ESS or DSM100 central office switch. A disclosed method provides the capability for EO switch enhanced functionality that is programmable from a remote location The dynamic logic system may be implemented across several elements, including a subscriber database called a Service Control Point (SCP), a computer called a Service Management Point (SMP) for controlling and distributing programmable logic to implement EO features, and an Edge Switching Point (ESP) for interacting with a physical device (telephone/data endpoint). The dynamic logic system may be introduced at the “intercept” layer between the physical edge switching point device, typically a telephone interface, and a routing network.
