Abstract: 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.

Abstract: Disclosed is a method for controlling handoff by a network infrastructure, which includes collecting channel information and transmitting the channel information to a Mobile Terminal (MT) and a method for controlling handoff by a MT, which includes receiving channel information collected by a network infrastructure and making a handoff decision according to the channel information. The present invention also discloses apparatuses for controlling handoff. Applying the present invention, the handoff decision will be made based on both the information collected by the network infrastructure and the information collected by the MT, therefore blind handoff is reduced, the network workloads are balanced and the QoS is assured before and after the handoff.

Abstract: 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.

Abstract: The embodiments of the present invention provide a method and an apparatus for establishing a virtual link.

Abstract: The present invention discloses a method for a wireless local area network terminal to access a network, a local area network system and a wireless local area network terminal. The wireless local area network includes at least one basic service set and at least one extended service set thereof constructed by a plurality of terminal equipments. In the invention, the extended service set has a uniquely identified extended service set ID, when performing channel scan, the extended service set ID parameter is added; and network selection is performed based on the extended service set ID parameter. Moreover, in the method according to the invention, network sharing may also be performed based on an extended service set.

Abstract: 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×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(logb(FW)), F being the number of fibers. One benefit of the new design may be maximized when W=O(F), b=O(F), and the worst-case number of cascaded conversions is O(1).

Abstract: 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×b space-switching elements, where b≧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(logb W), where W is the number of wavelengths per fiber. The wavelength-converter requirements are of between O(F) and O(F logb W), per stage and per plane, where F is the number of fibers.
