Systems and methods for integrating telephony and multimedia content include concurrently displaying a graphical user interface and a video channel of a media broadcast on a screen of a multimedia device. The graphical user interface has a graphical element by which an end-user of the multimedia device can select execution of an interactive application that invokes a telephony service. In response to a selection of the interactive application by the end-user, a message is sent to a networked resource requesting the telephony service. The requested telephony service can be to ignore, reject, or forward the incoming telephone call. Alternatively, the requested telephony service can be a click-to-call. Other interactive applications can request access to an address book, acquire presence information, or request an RSS (Really Simple Syndication) feed.

Streams of data traffic from various applications may be handled by a network-aware adapter module as part of a greater platform for filtering communicating the streams to intelligent network components. A distinguishing factor associated with a given data stream may be determined and used as a basis for selecting a QoS policy setting for the given data stream. The selected QoS policy setting may then be signaled to a media access control layer to take advantage of the QoS function of the embedded underlying active media type that is active and optimal (both from technical and business perspective) to carry out the communication for the application.

A method of redirecting content requests among content distribution network peers. In operation, a client sends a request for content to a content distribution network (CDN). When this CDN does not currently have the capacity to deliver the content, the CDN refers to one or more content distribution tables to see if the neighbor peers are able to provide this content. The content distribution table is populated at the time of distribution of the content. When the neighbor peer has this content, the request is redirected to the neighbor peer. In redirecting request, an address of the neighbor peer is appending to the previous address such that each peer receiving the request knows where the request came from and where it has been previously.

Content request routing method

A multi-staged services policer implements multiple policies, at an edge device of network, on the data traffic of a single customer. In such a multi-staged services policer, services policers in a given stage may receive information from policers in subsequent stages. This information may be used when policing in the given stage.

An overlay network includes a virtual content server for representing a content provider in a virtual content network and at least a client having a membership in the virtual content network and a content path between the virtual content server and the client. Each node in the content path is also a member of the virtual content network and each link between nodes is provided by a tunnel to ensure trust and integrity at the content level.

Overlay networks

The present invention generally relates to the acceleration of customer premises equipment based virtual private networks (CPE-VPN). To provide virtual private network service from an enterprise network to a mobile client in a secure manner apparatus and method are provided whereby VPN service is provided which allows the wireless network to use data acceleration techniques. This is accomplished by providing a VPN acceleration server that terminates VPN tunnel from the enterprise network, accelerates the data for wireless transmission then encrypts the data for transmission to the mobile client (VPN acceleration client) over an encrypted acceleration tunnel. The encrypted acceleration tunnel may use PKI encryption.

In a generic, end-to-end address resolution methodology, destination addresses in one format are translated into local addresses of different formats for purposes of routing calls across a plurality of interconnected networks which use different address formats. Translation of addresses is accomplished through either database query or by conversion algorithm. To facilitate routing across a particular network, the signaling message of the call is repacked with the local address as the routing address. The original destination address is preserved and carried transparently across that network. The signaling message is then repacked with the destination address as the routing address. Bi-level addressing schemes are supported, so that a network-level destination address and user-level destination address may both be carried transparently across a particular network.
