A mobile content delivery system that optimizes the delivery of especially bandwidth-consuming content (or the flow of any peak-hour data traffic) in a way that best utilizes the free capacity in the radio network, thus enabling considerably more efficient usage of the radio capacity. It also allows new services and pricing structures to be used in the cellular network, that otherwise would not be possible. The class of delivery of message content can be selected by the user on a transaction basis, or subscription-based and pre-defined in a user profile. By choosing a scheduled delivery the user can receive the content at a fraction of the price compared to instant delivery, since the content is sent at a time when the network is least utilized.

A design and proof of concept of a new type of WLAN, complete with simulation and results from the simulation has been described. Each AP Node is implemented as a self-contained embedded OS unit, with all algorithms resident in its Operating system. The normal day-to-day functioning of the AP node is based entirely on resident control algorithms. Upgrades are possible through a simple secure communications interface supported by the OS kernel for each AP node. Benefits provided by a wireless network, as proposed in this invention, are that: it installs out of the box; the network is self-configuring; the network is redundant in that mesh network formalism is supported, ensuring multiple paths; load balancing is supported; there is no single point of failure; allows for decentralized execution; there is a central control; it is network application aware; there is application awareness; there is automatic channel allocation to manage and curtail RF interference, maximize non interference bandwidth and enable seamless roaming between adjoining wireless sub networks (BSS) and it supports the wireless equivalent for switching—for seamless roaming requirements.

An IP address autoconfiguration method and system of an IPv6-based Low Power WPAN for reducing network traffics is applicable for an Internet Protocol (IP) based network including a plurality of devices. The address autoconfiguration method generates and broadcasts, at a first device, a beacon frame containing an adaptive router advertisement (RA) message having prefix information, and configures, at a second device received the beacon frame, an IP address using the prefix information extracted from the adaptive RA message carried by the beacon frame and a physical address of the second device. The system includes a first type device which broadcasts a beacon frame carrying a prefix; at least one second type device which relays the prefix using a beacon frame; and at least one terminal device which configures an IP address using the prefix in the beacon frame and a physical address of the terminal device.

The invention comprises a method and apparatus that prevents the activation of a congestion controlling process that would otherwise be activated in response any packet loss condition. The congestion controlling process is inhibited when a congestion parameter associated indicates that the packet loss condition is not caused by congestion.

Embodiments of the present invention provide for execution of a protocol in a multi-processor network device. In one embodiment, a hash function is applied to one or more fields of the data packet header to determine a unique index. A hash table is then queried, whereby data indicating one or more threads corresponding to said unique index is extracted. An available thread of execution, which has previously handled packet in the same receive stream, may thus be selected from a pool of threads. The selected thread of execution is then dispatched to provide for receive processing of the present data packet.

An N-dimensional lattice network that scales to capacities of the order of a Yotta bits per second (1024 bits per second) includes a plurality of sub-nets of edge module switches interconnected by an agile switching core. The agile core may be distributed. In the N-dimensional lattice network, each edge module 408 is connected to N core stages, each core stage having an associated dimensional indicator. The input / output ports of each edge module are divided into (N+1) port groups. One of the port groups serves local sources / sinks while the remaining port groups are respectively connected to core stages in each of the N dimensions. This structure permits virtually unlimited capacity growth and significantly simplifies the routing and forwarding functions. The edge modules are addressed using logical coordinates, one coordinate being assigned for each of the N dimensions. This simplifies routing and permits each edge module to compute its own routing tables.

The present invention relates to a method and network node for controlling packet flow in a buffer means (13; 14) of a network node of a data network, wherein a nominal capacity is assigned to each data flow, and an additional or free capacity is shifted from a first flow portion to a second flow portion when a new data packet of said second flow portion has been received and said nominal capacity has been exceeded. The nominal capacity may be an upper buffer memory limit used for controlling queuing of data packets in a buffer memory (13) of said buffer means, wherein the memory space of the buffer memory (13) is shared between a plurality of channels allocated to respective packet data connections. Then, the free capacity corresponds to a memory space shifted from a first channel to a second channel, when a new data packet of the second channel has been received and not enough memory space is available for the second channel. Thus, a dynamic buffer-sharing mechanism is provided which reduces the number of packet drops in the buffer memory (13) during congestion and improves network throughput. Alternatively, the nominal capacity may be a nominal flow rate at which data flow traffic is guaranteed in a QoS scheduling algorithm. Then, a residual rate corresponding to the difference between the nominal flow rate and an instantaneous traffic is shifted between flow portions of a buffer means controlled by the scheduling algorithm to maximize total system throughput.

An access point operates in an 802.11 wireless communication network communicating with a client station, and includes a smart antenna for generating directional antenna beams and an omni-directional antenna beam. An antenna steering algorithm scans the directional antenna beams and the omni-directional antenna beam for receiving signals from the client station. The signals received via each scanned antenna beam are measured, and one of the antenna beams is selected based upon the measuring for communicating with the client station. The selected antenna beam is preferably a directional antenna beam. Once the directional antenna beam has been selected, there are several usage rules for exchanging data with the client station. The usage rules are directed to an active state of the access point, which includes a data transmission mode and a data reception mode.
