Abstract
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.
