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.

Documents written using a markup language such as XML may be decomposed into Path and Parent Associated Node (PPAN) elements, each of which is a linear data structure that includes the content of a node, the parent-child relationship of the node, and the path level of the node. A number of PPAN elements may be grouped together to form A PPAN chain. A PPAN matching process uses the PPAN elements/PPAN chain to search for structured documents that match the PPAN chain. The PPAN matching process is able to perform query and match at the same time to accelerate the PPAN matching process, and also enables complex services to be represented by generic structured documents. Optionally, the PPAN matching process may support wildcard requests so that services may be discovered without prior knowledge of the services.

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 technique for transmitting an optical signal along an optical wavelength path through an optical network having a plurality of network nodes is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for transmitting an optical signal along an optical wavelength path through an optical network having a plurality of network nodes. Such a method may comprise transmitting a first message from a first node to a second node requesting an optical wavelength path from the first node to at least the second node, and simultaneously configuring the first node for transmitting an optical signal along the optical wavelength path from the first node to the second node.

A method and system for allocating bandwidth of a wireless channel to different types of traffic includes partitioning the bandwidth of the wireless channel into a plurality of contention periods. Traffic flows are associated with access categories, and one or more of the access categories are assigned to each contention period. During at least one of the contention periods, traffic flows associated with a proper subset of the access categories contend for access to the wireless channel.

Reliable quality of service (QoS) provisioning using adaptive class-based contention periods

Various techniques for queue management based on random early detection (RED) are disclosed herein. In particular, a method for generating a drop probability for an incoming packet in a device having a queue to buffer packets between segments of a network is provided. The method comprises determining, upon receipt of an incoming packet, a size of the queue and determining an error based at least in part on a difference between the queue size and a threshold. The method further comprises determining a drop probability for the incoming packet based at least in part on the error and a constant gain factor. The constant gain factor may be based at least in part on a linearized second order dynamic model of the network.

A technique for wave-mixing bulk frequency conversion in a network comprising one or more channels is disclosed that enables cost-effective wavelength-conversion. In one particular exemplary embodiment, the technique may be realized by a new class of multi-log wave-mixing-cross-connects that are based on arbitrary b&times;b space-switching elements, where b>2. In such cross-connects, for any light-path, the worst case number of cascaded frequency-conversions is O(log (FW)), F being the number of fibers. One benefit of the new design may be maximized when W&equals;O(F), b&equals;O(F), and the worst-case number of cascaded conversions is O(1).

A technique for wave-mixing frequency translation is disclosed. In one particular exemplary embodiment, the technique may be realized as a general construction for multi-log wave-mixing unicast or multicast cross-connects, with b&times;b space-switching elements, where b&gE;2. The resulting cross-connects support all-optical frequency-conversion, and they exploit multi-stage wave-mixing bulk frequency-translation In these cross-connects, for any light-path the worst case number of cascaded frequency-conversions is O(log W), where W is the number of wavelengths per fiber. The wavelength-converter requirements are of between O(F) and O(F log W), per stage and per plane, where F is the number of fibers.
