摘要： A web-based system is provided for generating binary images customized for different users in memory space constrained environments. Inputs from a user identifying a set of features of interest in a software program, and a maximum size of memory space available for storing the software program are received. A required size of memory space for the software program, including the set of features is computed. If the required size is more than the maximum size, the user is notified that the set of features cannot be fit into the available memory space. Otherwise, a corresponding binary image implementing both of a core functionality of the software program and the set of features of interest is built. The user can retrieve the binary image from the server via the client system.

摘要： A dual-mode device may compute an expected time instance of arrival of a first beacon based on prior received beacons. If the first beacon is received at an actual time instance which is in variance with the expected time instance, the device re-computes a sequence of future time instances of arrival of respective future beacons and schedules a sequence of station windows, with each station window to cover the corresponding future time instance of the sequence of future time instances and to have a desired first period. The dual-mode device operates in station mode in the sequence of station windows and in the AP mode in a sequence of AP windows, wherein each station window of the sequence of station windows is operated alternately with each AP window of the sequence of AP windows in a TDM manner, with each AP window having a desired second period.

摘要： A wireless station associates with an access point to join a wireless local area network (WLAN). The access point is part of the WLAN and operates as a switching device between wireless stations of the WLAN. The wireless station forms a TCP session via the access point with an external device which is external to the WLAN. The wireless station exchanges (i.e., transmits and/or receives) a first sequence of packets on the TCP session. The wireless station receives a frame from the access point, the frame indicating that the wireless station has been disassociated after having associated earlier with the access point. The wireless station re-associates with the access point. The access point then communicates with the external device on the TCP session after re-associating, the communicating involving exchanging a second sequence of packets with the external device after the re-association.

摘要： A wireless station (STA) of a wireless network transmits parallel data streams. The STA maintains transmission profiles, each corresponding to a respective data stream of parallel data streams. A transmission profile contains a set of rules or parameters, which are used for determining various characteristics in relation to transmission of packets in the corresponding data stream. The STA queues packets of each data stream in a corresponding queue. The STA selects a packet from a queue, and determines a transmission rate for the selected packet according to a transmission profile of the queue. The STA transmits the packet at the determined transmission rate. In an embodiment, the wireless network corresponds to an IEEE 802.11 network.

摘要： Router nodes of a wireless network deliver layer-3 multicast packets to subscribing end devices. In an embodiment, upon receiving a layer-3 multicast packet, a router determines a source that originated the layer-3 multicast packet. The router broadcasts at L2-level, the layer-3 multicast packet only if either one of a first condition and a second condition is satisfied. The first condition is satisfied only if (A) the source is not a descendant node of the router node according to the hierarchy, (B) the layer-3 multicast packet is received from a parent node, and (C) the layer-3 multicast address is subscribed to by a descendant of the router node. The second condition is satisfied only if (A) the source is a descendant of the router node, and (B) the layer-3 multicast packet is received from a child node according to the hierarchy, the source being reachable from the child node.

摘要： According to an aspect of the present disclosure, an access point sends timing information related to updating of a group key. A wireless station communicates with the access point according to the timing information to receive an updated group key. The updated group key is thereafter used for processing of multicast packets. Due to the use of the timing information, the wireless station can operate in a power-down mode, and yet receive at least the required group keys. In one embodiment, the timing information specifies a future time instance at which the update group may be available. In an alternative embodiment, a version number is associated with each value of the group key and the version number of the currently operative group key (in the access point) is broadcast to the wireless stations.
