Abstract: In one embodiment, the internal path traversed by packets between two user visible interface, selected by a user, is displayed. The path displayed includes internal interfaces traversed by the packets.

The control system communicates one or more control messages (e.g., Session Initiation Protocol or SIP messages) over the data network to establish a call session with a remote device in response to receipt of a request through the user interface. One or more commands are transmitted to a voice device associated with the control system to establish the call session between the voice device and the remote device over the data network. A Real-Time Protocol (RTP) link may be established between the voice device and the remote device.

Abstract: A traffic prioritization system and method performs a coarse classification of upstream bursts at the physical interface of a wireless communications device. The wireless device monitors and controls communications with a plurality of remote wireless communications devices throughout a widely distributed network, including the Internet. The traffic prioritization system includes a burst receiver that receives and sends the upstream bursts to a classifier. At an appropriate time, the classifier receives the upstream bursts and queries a priority lookup table (LUT) to determine a priority classification. The priority classification is used to separate the bursts into two or more priority levels. The higher priority level is used to designate services having a low tolerance for delay, such as telephony. Upon classification, the upstream bursts are forwarded to one of several priority queues. Each priority queue corresponds to at least one priority level.

Abstract: Principles of the invention relate to techniques for transmission of Layer 2 (L2) multicast traffic over a point to multi-point (P2MP) label switched path (LSP) within a multi-protocol Label Switching (MPLS) network. The principles of the invention include configuring circuit cross-connect (CCC) switches that transparently cross-connect L2 interfaces to a P2MP LSP within an MPLS network. The transparent cross-connections allow L2 multicast traffic to be encapsulated as MPLS packets regardless of the type of payload the L2 multicast traffic is carrying. A CCC switch may be configured within an ingress router of a P2MP LSP to cross connect an L2 interface to the P2MP LSP. CCC switches may also be configured within each egress router of the P2MP LSP to cross-connect each leaf of the P2MP LSP to one or more L2 interfaces.

Abstract: In a cable modem system, increasing or decreasing the rate of an MPEG Transport Stream involves two separate, but related, tasks: 1) incorporating a sufficient number of additional packets (or discarding packets) to make up for the difference in data rates between input and output, and 2) altering timing information (for instance, PCR (Program Clock Reference) values) present in some incoming packets to reflect their altered positions in the output stream. Both of these tasks can be facilitated by the use of a FIFO (First-In, First-Out) structure, through which the data flows.

Abstract: A data structure is stored in a memory of a router, the router located along a path between a source end station and a plurality of destination end stations in a multicast distribution tree. In response to receipt of trace packets containing a listing of network devices in the multicast distribution tree, the data structure is updated. When the source end station desires to send a multicast packet, it transmits a packet to the router. The router then writes the path information stored in the data structure into the packet. Such path information may include a tree list that specifies the arrangement of network devices along the multicast distribution tree and an address list that specifies the Internet Protocol (IP) addresses of these network devices along the multicast distribution tree. By storing the complete description of the network devices of the multicast distribution tree in the packet, routing demands on the devices along the multicast path are minimized.
