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: Link information is obtained about new or changes links in a communications system having a plurality of domains. The link information concerning a link between a first and a second domain comprises at least four pieces of information, domain identity of the first domain, domain identity of the second domain, link end identifier for a first end of the link, and link end identifier for a second end of the link. The link information is cascaded through the communications system by providing the link information stepwise from one domain to an adjacent domain. This is achieved by spreading the obtained link information to adjacent domains and by distributing link information received from adjacent domains to further adjacent domains. Preferably, the link information is compiled and access to the compiled link information is provided for creation of a system link map.

Abstract: The present invention relates to a method for retransmission of lost data, a receiving device operating according to the invented method and a retransmission server. In the absence of a unique identifier per data packet or data frame, there is obviously a problem to directly identify a specific data packet, data block or data frame in the stream and retransmission can't take place with current technologies. The object of the present invention is to offer a retransmission method and means for making said retransmission of missing data packets possible in the absence of a unique identifier.

Abstract: A method of enabling traffic flow classification on a node, which may be used for controlling the traffic flows on the same node or on another node of a communication network. A first mapping process is configured to manage an operation for linking an application process to a class, and a second mapping process is configured to manage an operation for linking an application process to a unique signature. A third mapping process is configured to manage a record of accumulated linking information, such that a traffic flows associated with an application process may be identified and such that a classification of the respective traffic flow can be recognised. The accumulated classification information may then be used for controlling purposes.

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.
