Abstract: In one embodiment, a network device comprises a tag processor configured to process a media stream received at the network device. The media stream is sent through a network to a desired destination. The tag processor comprises at least one of a tag inserter module and a tag module. The tag inserter module inserts a tag into the media stream, the tag indicating content of the media stream and the network device providing the tag. The tag module identifies and reports a value of a tag received within the media stream, and forwards the media stream to a user and/or compares the identified value to an expected tag value, and forwards the media stream to a user in the event that the comparison indicates a match. The present invention embodiments further include a method and logic for content tagging of the media stream.

Abstract: A communication system includes multiple routers interconnected by a packet-based communication network. Each of the routers includes a monitoring application that monitors quality of one or more packet flows during each of multiple successive monitoring periods. For each of the packet flows, the monitoring application determines quality metrics based on information obtained from transport headers of packets.

Abstract: A dispatching technique dispatches packets to a plurality of service control engines (SCEs) which in aggregate may be configured to handle traffic produced by a high-speed high-capacity data link. Upstream and downstream packets that are associated with a data flow between a subscriber and a destination node in a communication network are received from by a dispatcher which is located in a path used by the data flow. For each packet, the dispatcher identifies an SCE from among a plurality of SCEs that is to receive the packet based upon an address contained in the packet. The packet is then dispatched by the dispatcher to the identified SCE which processes the packet accordingly. After processing the packet, the SCE returns the packet to the dispatcher which further processes the packet including transferring the packet onto the communication network towards its destination.

Abstract: An internetworking device that provides improved immunity to Denial of Service attacks, and in general, improved Quality of Service (QoS). An internetworking element or other route processor is composed of two main parts, including a data forwarding plane and a control plane; the control plane runs routing, signaling and control protocols that are responsible for determining the packet forwarding behavior by the data plane. Independent control plane processes may be provided; however, they are considered to be a single network entity that is a uniquely addressable port. Packets thus intended for the control plane always pass through a designated point. As a result, a set of port services unique to the control plane may be applied to the control plane port. These control plane port services thus can be utilized to control all packet traffic entering and exiting the control plane processes as a whole.
