A technique for synchronizing a visual browser and a voice browser. A visual browser is used to navigate through visual content, such as WML pages. During the navigation, the visual browser creates a historical record of events that have occurred during the navigation. The voice browser uses this historical record to navigate the content in the same manner as occurred on the visual browser, thereby synchronizing to a state equivalent to that of the visual browser. The creation of the historical record may be performed by using a script to trap events, where the script contains code that records the trapped events. The synchronization technique may be used with a multi-modal application that permits the mode of input/output (I/O) to be changed between visual and voice browsers. When the mode is changed from visual to voice, the record of events captured by the visual browser is provided to the voice browser, thereby allowing the I/O mode to change seamlessly from visual to voice. Likewise, the voice browser captures events which may be provided to the visual browser when the I/O mode is changed from voice to visual.

The Translucent Proxying of TCP (TPOT) device and methods use TCP-OPTIONS and IP tunneling to guarantee that all IP packets belonging to a specific TCP connection will traverse the proxy which intercepts the first packet of data. This guarantee allows the ad-hoc deployment of TPOT devices anywhere within the communication network, and does not restrict the placement of proxy devices at the edge of the network. Furthermore, no extra signaling support is required for the TPOT device to properly function while the addition of TPOT devices to communication networks significantly improves the throughput of intercepted TCP packets of data.

A system and method for interacting with content, such as web-based markup content, using visual and voice browsers. A first browser facilitates communication in a first mode (e. g. , an HTML browser that facilitates visual/tactile interaction with HTML content), and a second browser facilitates communication in a second mode (e. g. , a VXML browser that facilitates audio interaction with VXML content). HTML and VXML content is created that: (1) indicates a correspondence between HTML and VXML pages that represent the same underlying content; and (2) contains specialized tags that indicate information to be send from one browser to the other to synchronize each browser to equivalent parts of the content. The HTML browser is adapted to use relative links as signals that information is to be sent to the VXML browser, and the platform on which the VXML browser runs is adapted to recognize a “hit” on its own port as a signal that information is to be sent to the HTML browser.

A technique for allowing an automated participant in a telephone conversation, such as an Interactive Voice Response (IVR) system or a voice browser, to react to the placing of the conversation “on hold. ” When a conversation between an automated participant and a human participant is placed on hold, a signal is provided to the automated participant indicating that the voice circuit between the two participants has been broken. In response to the signal, the automated participant may take appropriate action, such as suspending its participation in the conversation, extending the time for which it awaits a response from the human participant, continuing the conversation in a “visual” mode using the keypad and display on the human participant's handset, or some other appropriate action.

Multi-modal applications are capable of interacting with a user in a voice mode, a visual mode, and/or other modes of communication. Mode swapping refers to the process of changing from one mode of communication (or one combination of modes) to another. Mode swapping may be initiated by a user, by an application, or by another entity. Mode swapping may be performed “adaptively,” in that an entity monitors the effectiveness of a communication mode and initiates a mode swap if communication is proceeding non-optimally in the current mode. Mode swapping may be performed by dropping a call to a telephone terminal in the currently-open mode and placing a call to that same device in another mode. In one embodiment, logic for mode swapping resides on a gateway proxy that mediates communication between an application and a telephone terminal.

The present invention provides an architecture that advantageously leverages multiple content distribution networks to provide enhanced services. In accordance with an embodiment of the present invention, a share of content requests are served by each of a plurality of content distribution networks. The fraction of content requests served by a particular content distribution network can be determined dynamically, depending on the offered load or other traffic characteristics.
