Abstract: Techniques for estimating a position of an observing station are disclosed based on capturing, at the observing station, a first and a second FTM message exchanged between a first messaging station and a second messaging station. At the observing station, a first time of arrival of the first FTM message and a second time of arrival of the second FTM message may be determined. Based on contents of one or more FTM messages, a first transmission-related time associated with the first FTM message and a second transmission-related time associated with the second FTM message may be obtained. The position of the observing station may be estimated based on (1) a position of the first messaging station, (2) a position of the second messaging station, (3) the first time of arrival, (4) the second time of arrival, (5) the first transmission-related time, and (6) the second transmission-related time.

Abstract: A method for carrying data on a live host signal, comprising the steps of: varying timing in a host signal in response to data to be encoded, wherein variations in timing are smaller than a sampling period for detection and capture of the digital signal receiving the live host signal; sensing pulse timing variations in the received live host signal by comparison to a reference signal; and determining information in the sensed timing variations.

Abstract: Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.

Abstract: A method and poll control entity (300) for controlling a polling procedure in a radio communication where a data transmitting node (302) transmits data (3:1) to a data receiving node (304) and sends polls to the data receiving node according to a default polling frequency. The polls require the data receiving node to send feedback (3:2) to the data transmitting node indicating whether said data has been received and decoded by the data receiving node or not. The poll control entity detects (3:3a-c) a trigger of the radio communication indicating a deviation of a feedback time which is a time period between a time of sending the poll and a time of receiving the feedback from an expected feedback time range. The poll control entity then adjusts (3:4) the polling frequency based on the detected trigger such that the deviation of the feedback time is reduced, and enforces (3:5) the adjusted polling frequency at the data transmitting node. In this way, the polling frequency can be dynamically and individually adapted to the current situation of traffic load and/or radio conditions which may influence the resulting feedback time in the radio communication, to achieve efficient communication of data and good throughput.

Abstract: Described embodiments include a system that includes a network interface and a processor. The network interface is configured to receive, at a first time, a packet transmitted from a source communication terminal over a communication network en route to a target communication terminal, before the packet passes through a particular portion of the communication network, and to receive the packet at a second time, after the packet has passed through the particular portion of the communication network. The processor is configured to delay the packet, subsequently to the packet being received at the second time, by a delay duration that is a decreasing function of a duration between the first time and the second time, and to send the delayed packet, subsequently, via the network interface, en route to the target communication terminal. Other embodiments are also described.

Abstract: It is described a network attack detection method. A topology analysis on network is conducted to obtain a probing path set containing at least one probing path. A first probing path contained in the probing path set is probed by using a probing pattern to obtain a performance metric of the first probing path. It is determined whether the first probing path is subjected to network attack according to the performance metric and a control performance metric.
