摘要： Malicious network node activity and, in particular, denial of service attacks, may be mitigated by one or more practical mitigation mechanisms and mitigation mechanism combinations. Suitable protocol messages may be challenged with a challenge probe. A response to the challenge probe may be utilized to determine if received protocol messages are illegitimate, that is, originated by a malicious network node. Received protocol messages may be classified as questionable protocol messages. For efficiency, protocol message challenges may be limited to protocol message classified as questionable. A sequence number limit may be calculated as a function of receive window size. Transmission control protocol messages may be determined to be illegitimate by comparing the acknowledgement number field with the calculated sequence number limit. Randomized selection of source port numbers for transmission control protocol connections may also mitigate malicious network node activity by resulting in legitimate protocol message field values that are less predictable.

摘要： A computing device operating according to a frequency division multiplexed protocol in which communication occurs over a signal formed from a plurality of sub-channels selected from anywhere in a frequency spectrum. A computing device may select sub-channels cognitively by using information about sub-channels previously deemed suitable or unsuitable by that computing device or other computing devices. A described technique for determining sub-channel suitability includes analyzing radio frequency energy in the sub-channel to detect signals generated by another computing device or high noise levels. Information may also be used to cognitively select sub-channels to be analyzed, such as by first selecting for analysis previously-used sub-channels.

摘要： A computing environment containing a mesh network that is adapted to provide a reliable transport mechanism over which services may be delivered. Nodes of the mesh can automatically select routable addresses without conflicts, which allows nodes of the mesh to be accessed, even as the mesh changes through the addition or deletion of nodes. Also, nodes communicate with a protocol that supports service advertisements. These advertisements can identify mesh nodes that supply services, such as file or print servers, for which devices that have not yet connected to the network may be searching. Advertisements can also identify services to be used by nodes in the network, allowing, for example, a node to select a gateway providing a reliable connection to an external network. The mesh network can be used as a transport for communication using protocols, such as TCP/IP, that generally exhibit poor performance when using unreliable transports.

摘要： A system facilitates managing one or more devices utilized for communicating data within a telepresence session. A telepresence session can be initiated within a communication framework that includes a first user and one or more second users. In response to determining a temporary absence of the first user from the telepresence session, a recordation of the telepresence session is initialized to enable a playback of a portion or a summary of the telepresence session that the first user has missed.

摘要： A communication system in which an access point and one or more devices communicating through the access point adaptively apply Orthogonal Frequency Division Multiple Access (OFDMA). The access point may assign orthogonal subcarriers to devices as in conventional OFDMA, but the access point senses activity on the subcarriers and selects subcarriers without activity for assignment. In an alternative approach, a device that is configured for OFDMA communication may receive a channel assignment from a device that does not support OFDMA. The OFDMA-capable device may use only a portion of the subcarriers in the assigned channel, which may be communicated to the non-OFDMA device. During the non-OFDMA device may then ignore unused subcarriers in error detection and correction to avoid incorrectly classifying communications as erroneous. Information about OFDMA capabilities, subcarrier assignments and subcarriers in use may be communicated as information elements in network control communications, such as beacons and probe messages.
