The invention relates to discovering a path in a communications network. Embodiments of the invention disclose determining whether at least two server trail termination points (TTPs) of the path are compatible, creating a server trail between the at least two TTPs, determining whether each TTP is framed by a respective client connection termination point (CCTP) of a higher layer, assigning a respective CCTP to each of the two TTPs, creating a link connection between the respective CCTPs, determining if one of the respective CCTPs is associated with a higher layer TTP, and if it is not so associated then determining if one of the respective CCTPs is constrained to a single TTP. The embodiments of the invention allow paths in a network to be determined after a change has taken place or a physical link has been created. |
