  • Patent number: 8199760
    Abstract: Policy-based routing of packets over a peer-to-peer, quality of service connection includes sending a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between a source peer implemented on at least one device and a destination peer implemented on at least one device. Packets originating from an application requiring a specified level of service are transmitted, from the source peer implemented on at least one device, over the peer-to-peer, quality of service connection. Packets originating from an application that does not require the specified level of service are transmitted, from the source peer implemented on at least one device, over a best effort connection.

  • Patent number: 7937483
    Abstract: A system and method of routing data packets is disclosed. In a particular embodiment, the method includes receiving a first Internet Protocol (IP) data packet at a first access port of an access line card within a data router. The method also includes transmitting the first IP data packet from the first access port to a network line card within the data router, via a first trunk port of the access line card. The first access port is coupled to the first trunk port and not coupled to at least one other access port. The method further includes receiving a second IP data packet at a second trunk port of the access line card from the network line card. In addition, the method includes transmitting the second IP data packet from the second trunk port to a second access port of the access line card.

  • Patent number: 7839866
    Abstract: Communication between a source and a destination is dynamically established. A connection request is received. The connection request is based on a request transmitted over a best-effort path from the source. A network connection is established having a specified quality of service (QoS) based on the request between the source and the destination. Data for a first application is transmitted over the network connection and data for a second application is transmitted over the best-effort path.

  • Patent number: 7773503
    Abstract: VoIP traffic bandwidth through a router port is controlled so that it does not exceed a predetermined bandwidth to ensure a desired quality of service for all VoIP calls routed through the port. Information of a packet received by the port is extracted from a packet header. The information includes source and destination addresses and port numbers as well as the bandwidth used by the packet. If the packet is from an existing call, the packet is routed and the time the packet was received is updated. If the packet is from a new call, it is determined whether the port has sufficient bandwidth to route the new call. If the port has sufficient bandwidth, the packet is routed, bandwidth is allotted for subsequent packets from the new call, and the port information is updated to accept the subsequent packets. If the port does not have sufficient bandwidth, the packet is dropped.
