摘要： A method for signalling of data transmission path properties is proposed. The method contains several steps at a first network endpoint device. As a first step, at least one data transmission path is provided via a client-server interface to a client device by the first network endpoint device. The data transmission path is a path through the network connecting the first network endpoint device and a second network endpoint device. As a second step, the first network endpoint device receives via a server-network interface OAM information generated by the second network endpoint device or internal network devices and terminates this received OAM information. As a third step, the first network endpoint device determines at least one data transmission property parameter from such received OAM information which was generated by the second network endpoint device or internal network devices. The fourth step is that of signalling via the client-server interface at least one transmission property message towards the client device in dependence on the at least one determined transmission property parameter.

摘要： The present invention provides for a method for Enhanced Equipment Protection Switch for Customer's device Dual-Homing, in an interconnection between a Central site/Pop and a Transport Network Hub by two boards. Each board is simultaneously connected to the Switching Matrix of the Transport Network Hub with B/2 bandwidth. Both boards receive the band B from the Central site/Pop, and send half a band B/2 directly to the Switching Matrix, and the other half band B/2 to the other board.

摘要： Described is a method extending the OAM functionality in the RPR networks through a new OAM loopback procedure of request-reply type together with the definition of a new RPR OAM loopback frame. The OAM loopback function allows any RPR station to check the reachability of another RPR station. It is not necessary to stop any data traffic communication on the network in order to perform this function.

摘要： It is disclosed a method for in-band path failure detection localization in a SDH/SONET network, the network comprising at least one network domain, the method comprises the steps of defining at least one path (PATH) through which SDH/SONET frames are transmitted and is characterized by coding K3 byte of POH, for SDH technology, or coding the Z4 byte of STS1 POH, for SONET technology. Bits 1-6 of byte K3 or Z4 are coded for providing: a node identifier indicating a node detecting a failure; Remote Defect Indication information; and information relating to the fact that a failure is external or internal to a network domain.

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.
