摘要： According to a first aspect of the present invention, it is described a probing method, arrangement and system for estimating condition, such as available bandwidth, of a data path (22) of a network comprising nodes (21, 23) using support from the probe-packet sender node (21 ) only. The probe-packet sender node (21 ) transmits probe packets (24) with a first inter packet separation (IPSsent) a time-to-live (TTL) towards an intermediate node (23). Control message packets (24b) are then generated by the intermediate node (23) when time-to-live (TTL) expires. The probe-packet sender node (21 ) receives the control message packets (24b) and calculates a received inter-packet separation. Sent (IPSsent) and received (IPSreceived) inter-packet separation is all that is needed to produce an estimate of the data path condition.

摘要： 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.

摘要： Information about virtual private networks -VPNs - in each domain (10A-E) of a multi-domain communications system (1) is provided. By comparing a request (31) for a configuration of a VPN with the provided information of other connected domains, a match can be found. VPN configuration can then be performed based on the outcome of the match. The provided domain VPN information is in one embodiment spread to other domains under constrictions put by SLAs between domain operators. The spreading of VPN information can be performed regularly or triggered by an external event. In another embodiment, the VPN configuration request is instead spread to different domains.
