Abstract: A method of identifying traffic flows is provided in a traffic generating node, where each traffic flow is being associated with an application process running on the traffic generating node. The method is configured to perform a mapping operation, such that an application process is being linked to a signature that uniquely identifies a traffic flow and an associated socket, and such that the obtained linked information is maintained in a list. The mapping operation is configured to be executed in response to recognising a change to a socket associated with the application process at the traffic generating node. Based on accumulated mapping information, one or more processing element located at the traffic generating node, or at another node, may classify and/or control traffic flows associated with any of the application processes of the traffic generating node.

Abstract: A probing method, arrangement, and system for estimating a condition, such as available bandwidth, of a data path in a communication network including multiple nodes are described. A probe-packet sender node transmits probe packets with a sent inter-packet separation and a time-to-live towards an intermediate node. Control message packets are generated by the intermediate node when the time-to-live expires. The probe-packet sender node receives the control message packets and calculates a received inter-packet separation. An estimate of the data path condition can be generated based on the sent inter-packet separation and the received inter-packet separation.

Abstract: A system and method for determining end-to-end available bandwidth of a path in a packet-switched communication network. A multi-rate packet chirp injector injects probe traffic packets at different probing rates, u, into the network utilizing a probe chirp. A receiver samples time separation of the probe traffic packets to generate time-separation samples, which are used to calculate relative inter-packet separation strain, ?, samples at different probing rates. An Expectation-Maximization, EM, analyzer utilizes an EM algorithm to identify useful strain ? samples and to estimate parameters of a line l2 representing a direct linear relationship between the probing rate and the inter-packet separation strain ? at probing rates greater than a break point. A filter such as, for example, a Kalman filter then determines the available bandwidth of the network path based on the estimated parameters of the line l2.
