摘要： A method is described for managing and propagating a failure indication in a telecommunication system. The telecommunication system comprises at least a synchronous transport network and a packet-switched network which is connected to the synchronous transport network by means of a node having a transport side towards the synchronous transport network and a packet side towards the packet-switched network. According to the invention, the method comprises the following steps, which are performed by said node: detecting a first failure at the transport side; performing consequent actions in the output direction at the packet side; detecting at the packet side a second failure which is caused by said consequent actions; and ignoring the second failure.

摘要： A method, a device and a system for interconnecting a multi-protocol label switching (MPLS) network and an Ethernet are provided. A packet sent by a node located at the Ethernet is received, the packet is parsed, the parsed packet is re-encapsulated by means of MPLS, and the re-encapsulated packet is sent to a node located at the MPLS network, so as to implement interconnection between the MPLS network and the Ethernet. A reverse solution is similar to this. An intermediate node in the solution adopts a manner of parsing a packet and then re-encapsulating the packet when the packet is sent from one network to another network, instead of transparent transmission only. Therefore, it is unnecessary to configure a Media Access Control (MAC) address of a remote node on a node located at the Ethernet and to configure Ethernet information on a node located at the MPLS network.

摘要： In order to facilitate the transport of 1 Gbit/s Ethernet signals over an Optical Transport Network using the Optical Transport Hierarchy as specified by ITU-T G.709, a new OTH entity referred to as Optical Channel Data Unit-0 (ODU0, 101) with a capacity of approximately 1.22 Gbit/s is defined. This new entity fits perfectly into the existing OTH multiplexing structure, allowing the transport of two times a 1 Gbit/s Ethernet client layer signal within the capacity of one ODU1 (110), while being individually switchable. A 1 Gbit/s Ethernet signal (102) can be mapped into the ODU0 payload (103) using the Transparent Generic Framing Procedure (GFP-T) encapsulation technique as specified in Rec. G.7041.

摘要： A system and method for reducing frame leakage in a VLAN defined in an Ethernet OAM network. Upon receiving a unicast OAM frame at a Maintenance Intermediate Point (MIP) entity, a first database is queried to verify it the frame's destination address (DA) is provided therein. If not, a second database is queried to verify the frame's source address (SA) is associated with a Maintenance End Point (MEP) entity provided therein. If so, OAM domain level information corresponding to the MEP entity is obtained and a multicast MAC address associated with the OAM domain level is determined. The incoming OAM frame's DA is then replaced with the multicast MAC address for forwarding the frame to a set of port addresses restricted to the OAM domain level.
