摘要： In general, techniques are described for extending routing protocol advertisements to include respective attributes of constituent links of an aggregation group. In one example, a network device includes a management interface that receives configuration information that specifies first and second constituent links for a layer two (L2) aggregated interface. The first and second constituent links are physical links connected to respective physical interfaces of forwarding units of the network device. A routing protocol daemon of the control unit generates a link state message that specifies layer three (L3) routing information associated with the aggregated interface and further specifies an attribute of the first constituent link and an attribute of the second constituent link. The routing protocol daemon sends the link state message from the network device to another network device of the network in accordance with a routing protocol.

摘要： A method, a network, and a node each implement the transmission of Automatic Protection Switching (APS) switching coordination bytes across an OTN network. A working signal and a protection signal are received, one of which is designated as an active signal. The active signal is encapsulated in an Optical channel Data Unit (ODU) signal. APS switching coordination bytes from the working and protection signals are placed in an overhead segment of the ODU signal. The ODU signal is transmitted into and received from an Optical Transport Network (OTN) network. The working and protection signals are recreated based on the active signal encapsulated in the ODU signal and the APS switching coordination bytes in the overhead segment. The recreated working and protection signals are transmitted. In this manner, a single ODU signal may be used to transmit both the working and protection signals.

摘要： A method and apparatus for transceiving multiple service data from multiple communication services to a SONET/SDH communication system or network is provided. A SONET/SDH universal framer (SURF) bidirectionally provides communication between a SONET/SDH communication port and multiple service communication ports using their native data format. A provisioning register stores provisioning information describing the communication system and the communication ports. A SONET/SDH byte engine processes complex hierarchical SONET/SDH frames storing intermediate states when it changes to process a byte of data of a different STS-1 equivalent frame in a SONET/SDH STS-N frame. A service byte engine processes the multitude of service data formats and generally its intermediate states are restored, processed, and saved when it changes to process a different data stream or a different frame of data of a given service. An elastic storage means allows the SONET/SDH byte engine and the service byte engine to operate independent of one another in an asynchronous mode.

摘要： When multiple SDH/SONET frame are accumulated and then lower-order path information removed from multiple frames is multiplexed into the same packet to achieve better transmission efficiency during packetization, the delay for accumulating increases. Disclosed is a transmission device that packetizes an SDH/SONET lower-order path with timing which is an integer factor of 1 cycle of the SDH frame. In this case, the destination loads the same multiple lower-order path in one packet. The result is that delay time accompanying lower-order path packetization is kept to less than the time of 1 cycle of the SDH frame, and the efficiency with which lower-order paths are accommodated in packets is further increased. The result is that improved transmission efficiency is realized.
