Abstract: The present invention provides an audio source selection process for a conference bridge. The conference bridge receives multiple audio sources and selects at least one of the audio sources based on the relative signal levels associated with the audio signal at each of the audio sources. The audio signals associated with the selected source are delivered to conference participants via one or more audio outputs. The conference bridge will repeatedly employ a selection process to select an audio source based on signal level measurements for the audio signals of the audio sources. During the selection process, the influence of a selected audio source relative to the other unselected audio sources is reduced, after the selected audio source has remained selected for more than a first time period.

Abstract: Application program network service requests are translated into specific actions that are then performed through the management plane and/or control plane. The translations and resulting actions are responsive to previously defined policies for the communication network, and may further reflect processing of previous service requests by the same or another application program. The amount of resources available for use by a given application program may be predefined based on a globally defined network policy. Each service request obtained from an application program may be translated into multiple actions performed using various specific protocols and/or interfaces provided by either the management plane, the control plane, or both the management and control planes. Reports of network activity, status and/or faults for a requesting application program may be tailored to the requesting program's view of the network, and passed directly and exclusively to the requesting program.

The invention is also directed to apparatus and software for performing the methods.

Abstract: A level of interference affecting signal components of received communication signals is estimated and used to weight the signal components. The signal components in a each of a number of groups of signal components are weighted based on respective interference estimates to thereby adjust signal components for colored interference, which may vary significantly between different groups of signal components. Each group of signal components may include a single component or components within a relatively narrow sub-band of the communication signals, such as a coherence bandwidth of an Orthogonal Frequency Division Multiplexing (OFDM) signal.

Copying may involve copying multimedia content from an application while the application is using the multimedia content. There is also provided a method, apparatus, processor-readable medium and signals for providing a presentation by identifying multimedia content previously identified by a user as to be included in the presentation and accessing and presenting at least some of the multimedia content previously identified by the user.

Abstract: Described are a network, network device, and method for a method of distributing routing information for a virtual private network (VPN) application through a packet-switched network (PSN) having fully meshed provider edge (PE) routers through Provider Backbone Bridge (PBB) tunnels. Each PE router is configured to support at least one VPN and to run a BGP (Border Gateway Protocol) as an auto-discovery process for finding one or more other PE routers attached to the same VPN. A given VPN is associated with a PBB tunnel. A service instance identifier (I-SID), as defined in IEEE 802.1ah, is assigned to the VPN. Each PE router advertises membership in the VPN by including the I-SID assigned to the VPN in a BGP message issued during the auto-discovery process.

Each potential routing solution is based on at least one measured wireless communication parameter between internal nodes. Metric calculations for each potential routing solution are computed to determine a preferred routing solution. The wireless mesh network is configured to route traffic using the preferred routing solution.

Abstract: Methods and devices for logically segmenting an LSP so that OAM DTUs may be used to determine the performance and/or the status of LSP segments. To segment a previously determined LSP, a dedicated subpath (a logical LSP) within that predetermined LSP is defined between two LSRs that are capable of processing OAM DTUs. The source node (source LSR) establishes a logical LSP between itself and the destination node (destination LSR) using an LDP. In doing this, the logical LSP traverses a specific path and transits through specific nodes in that path. The source node then transmits an OAM DTU or any other specialized DTU to the destination node using a label specifically associated with the logical LSP that was established. The characteristic of the specific path traversed by the logical LSP can thus be determined by when, how, and if the specialized DTU is received by the destination node.

This ME-ARP allows the building of independent IP based Virtual Private LAN segments (VPLS) over a multicast enabled IP backbone using stateless tunnels and optimal VPLS traffic forwarding. Each VPLS has an associated IP subnet which is completely independent from other VPLS or the underlying IP backbone itself. Each Customer Premises Equipment (CPE) device needs only to be configured with a VPLS identifier and its serving IP subnet per VPLS designated interface.
