摘要： A method of localizing failures occurring along a transmission path is provided. A data signal is transmitted along the transmission path, which comprises a path segment. A first network node performs a tandem connection monitoring source function of a tandem connection. A second network node monitors the transmission along the path segment, by performing a tandem connection monitoring sink function. When the first network node detects a failure of the data signal, the first network node enters information indicating a data signal failure into the data signal's overhead field. When the second network node detects a failure by the tandem connection monitory sink function, the second network node enters information into the overhead field. When a third network node detects a failure of the data signal, the third network node uses the information in the overhead field to determine whether the failure occurred within or outside of the path segment.

摘要： It is disclosed a method of monitoring, a Multi-Protocol Label Switching network, a tandem connection of a Label Switched Path. The tandem connection to be monitored has an input node and an output node. The method comprises the following steps: receiving a first Operation Administration Management packet at the input node; and generating a second OAM packet at the input node. According to the invention, the following steps are further performed: a tandem connection header is inserted into the first OAM packet; both the first OAM packet with the tandem connection header and the second OAM packet are sent towards the output node; and the second OAM packet is identified according to the presence or absence of said tandem connection header.

摘要： A method of dynamically adjusting a transmission capacity of a data transmission connection is proposed. The method comprises different steps at a network end node. An incoming frame-structured time division multiplex signal carrying incoming timeslots is received from a client. Furthermore, a request data set comprising for at least one incoming timeslot a corresponding subset is received. The subset has an identifier for identifying an existing data transmission connection and a status indicator for indicating to the network end node a status requested by the client for the corresponding timeslot. If the status indicator indicates a request for adding the timeslot to the data transmission connection or removing the timeslot from the data transmission connection, the network end node adjusts the transmission capacity of the data transmission connection. If the status indicator indicates valid data in the incoming timeslot, the network end node transmits the data of the incoming timeslot via the existing data transmission connection to a far-end network end node.
