摘要： A first network device enables active measurement in a network path between a second network device acting as a controller of a network performance observability protocol and a wireless device. The first network device captures a measurement packet from the second network device; determines a destination of the measurement packet; and determines a measurement model associated with the destination. The measurement model represents a correspondence between one or more parameters related to the wireless device and estimated values of a measurement for the wireless device. The first network device determines a current value of a parameter related to the wireless device; determines, based on the current value of the parameter and the measurement model, a current estimation of the measurement for the wireless device; and responds to the measurement packet based on the current estimation of the measurement while avoiding to transmit the measurement packet to the wireless device.

摘要： A processor implemented method for monitoring the performance of a message queue for communication between processes. The method comprises, by an initiating process, publishing a trigger message to a first topic in the message queue, wherein the trigger message identifies one or more performance metrics and at least two processes that communicate via the message queue. By one or more of said processes, retrieving the trigger message from the first topic in the message queue; performing a measurement on a message or messages exchanged between the processes over the message queue, wherein the measurement determines the one or more performance metrics; and publishing the one or more determined performance metrics to a second topic in the message queue. The method also comprises, at a receiving process, retrieving the published performance metrics from the second topic in the message queue.

摘要： The application relates to a method and a node (110) for distributed performance monitoring in a communication network (100) comprising a set of nodes (110-160). Each node in the set is configured to operate alternatively as a monitor node or as a sensor node and wherein each monitor node in the network is configured to perform measurements together with a corresponding sensor node. The monitor node (110) determines (from a priority list) the sensor node (140) which has the highest priority and sends a first query (181) to that sensor node (140). The sensor node (140) on its side has a listening period for receiving queries. When the listening period expires, the sensor node (140) selects the monitor node (110) having the highest query priority and performs measurements 15 together with said selected monitor node (110).

摘要： The present invention relates to a method and arrangement for estimating available bandwidth of sub-path of a data path. The solution is based on the sending of probe packet trains comprising inner and outer packets from a start node to an end node using different TTL values for the outer and inner packets of these probe trains. By comparing measurements using different TTL values of the inner packets, it is also possible to determine which link are the local tight link and what available bandwidth it has.
