In a network interconnecting a plurality of content providers and a plurality of clients, for providing content to a client, each of the plurality of content providers is coupled to at least one content distribution network of a plurality of content distribution networks, wherein the client is coupled to at least one of the plurality of content distribution networks and a request for the content is sent from the client to a redirector node that receives requests, wherein a redirector at the redirector node provides an address for a server available to serve the requested content. When the client's content distribution network is a primary content distribution network for the content provider providing the requested content, redirecting the client to a server within the client's content distribution network. When the client's content distribution network is not a primary content distribution network for the content provider but the client's content distribution network has a content peering relationship with a primary content distribution network for the content provider, redirecting the client to a server within the client's content distribution network. When the client's content distribution network is not a primary content distribution network for the content provider and the client's content distribution network does not have a content peering relationship with a primary content distribution network for the content provider, redirecting the client to a server outside the client's content distribution network. The redirecting can be done using a domain name service (DNS) server that responds to requests for domain name resolution that include metadata encoding for the content being requested and / or attributes of the resolution request other than a domain name or explicit client / redirector communication to perform the redirection.

A method of determining a channel estimate of a first transmission channel in a communications system. The method comprises deriving a first set of channel estimates from symbols received through said first transmission channel; deriving a second set of channel estimates from symbols received through a second transmission channel in the communications system; determining a scale factor between the first and second sets of channel estimates from a least squares error criterion; and determining the channel estimate of the first transmission channel as a channel estimate of the second transmission channel scaled by the determined scale factor.

Systems, methods, and devices for controlling and limiting use of functions, such as calling, texting, chatting, emailing, Internet surfing, and similar applications, on a mobile device when the mobile device is in a moving vehicle, includes use of an on-board computer installed within the vehicle, a transmitter in electronic communication with the on-board computer that periodically transmits speed data of the vehicle to a receiver installed on the mobile device, wherein the mobile device includes suitable software and a rules-based policy that define and control when and which functions of the mobile device are disabled or interrupted by the software when the vehicle is in motion above a minimum threshold speed. Policies are set by default but may be customized for particular individuals, devices, or circumstances. Policies may also be customized for particular groups or subgroups of employees or contractors for company or legal compliance to reduce distracted driving.

In an automated exchange system means are provided by means of which a market maker can enter a course of action in advance, so that the volume in the orderbook is continuously updated, and where the updating is performed differently with respect to different counter parts. Also, quotes that may result in a trade between Market Makers are hidden for some time before being matched, thus giving the Market Makers a chance to back off. The system employs a function that supports that Market Makers through pre-defined parameters will have new orders generated by the system and that a market maker can act differently with respect to different counterparts. The parameters specify if a Market Maker should add extra volume on an existing price or generate a new order at a worse price. In order to make it possible for market makers to have a very tight spread without forcing them to take larger risks, additional logic is used when matching orders. The algorithm used for this purpose protects the market makers in certain situations and gives market makers the possibility to have a tight spread without taking a large risk. The algorithm also supports that the market makers can take the risk to quote large volumes.

Methods and apparatus for providing synchronous playback of the same piece of time-based media on multiple devices connected over heterogenous channels consisting of varying degrees of delay. The preferred embodiment of the invention is a handheld music player that uses a Wi-Fi or Bluetooth communications link to enable users to share music with similar nearby players and to synchronously play back the same music different players simultaneously. Users of all players tuned into one source hear the same thing at the same time, enabling the feeling of a shared music experience. Users can also use their players to exchange profile information and text messages.

Methods and apparatus are disclosed for providing a virtual assistant to at least one party of a communication. The virtual assistant is injected into the communication, for example, by a VXML engine. The operation of the virtual assistant is controlled by one or more software modules that are obtained from a proxy node. The software modules allow commands received from or destined for the party to be interpreted. The virtual assistant may optionally be customized based on a selection of the one or more supported external applications. The proxy node provides at least one method for the party that allows the party to access functionality provided by at least one external application. The proxy node interprets signals from the virtual assistant; converts the signals from the virtual assistant into commands for the external application; and converts one or more of commands, messages and data from the external application into signals understood by the virtual assistant.

A system and method for Internet Protocol (IP) flow classification group IP flows in a packet-centric wireless point to multi-point telecommunications system is disclosed. The method comprises analyzing an IP flow in a packet-centric manner, classifying the IP flow, scheduling the IP flow for transmission over a shared wireless bandwidth between a wireless base station and at least one subscriber customer premises equipment (CPE) station, allocating the shared wireless bandwidth to a communication of the IP flow between the wireless base station and a subscriber CPE station so as to optimize end-user quality of service (QoS) associated with the IP flow.

In one embodiment, the first computer is accessible via a web browser so a remote user can control or operate the conference room devices. The conference room devices may include facility devices, such as room lights, thermostat, door lock, drapes, etc. in addition to audio / visual equipment, such as VCR's, projectors, screens, and cameras, for example.

A conference server enables collaborative communications among a variety of client processes of varying configurations all operatively coupled over a computer network to each other and to the server. The server receives audio streams from participating client processes in a conference, selects which audio streams are active, and broadcasts one or more of the active audio streams to the client processes participating in the conference depending on the clients receiving capabilities and the conference parameters. The client processes receiving multiple active audio streams perform mixing locally at the client node. Without having to perform mixing at the server, resources are saved and the number of simultaneous participating client processes to the conference may be increased accordingly. The server is further capable of simultaneously accommodating multipoint clients and non-multipoint H.323 clients, as well as operating in multiway and “push to talk” modes.
