摘要： An existing path in a connection-oriented network requires resizing from a first size to a second size. Nodes exchange control plane signalling with other nodes which advertises available resources on links between nodes. A node on the existing path receives a request to establish a path capable of being resized to the second size. The node determines, using information acquired by the control plane signalling with other nodes, a new path between nodes capable of supporting the second size. The node signals to establish the new path and switches traffic from the existing path to the new path. The node causes the new path to be resized to the second size. Nodes exchange control plane signalling with other nodes which advertises whether a link supports resizing, such as OSPF-TE advertisements.

摘要： In an optical transport network a traffic flow comprises data grouped into a number of resizable data units, encapsulated by optical transport frames, each having a frame overhead. A rate of the traffic flow is changed by changing the data unit overhead and changing at the source node the frame overhead to indicate a change in rate of an optical signal carrying the traffic flow. An optical transmission part is tuned to transmit at the new rate, and at any intermediate nodes along the route the indication of the change in rate is detected in the frame overhead so that the traffic flow on a next optical link is transmitted at the new rate. Thus optical bandwidth allowed for enlarging the data units, can be saved, and electrical processing of data units at the nodes can be simplified, reducing power consumption.

摘要： Configuring a node (410) of a synchronization network involves identifying (10) possible alternative time synchronization trails arranged to carry time synchronization information for time synchronization at the node, and possible alternative frequency trails, arranged to carry frequency synchronization information for frequency synchronization at the node. Using information about the sources (20), a comparison of the trails (30) is biased to increase a likelihood of choosing time synchronization and frequency trails which share the same source, over a likelihood of choosing trails with different sources. This can help avoid divergence and consequent bit errors arising from phase errors, resulting from trails having different sources. It can encompass for example changing both to a new common source, or changing one or both trails while still using the old common source.

摘要： An optical transport network signal (OTM) comprising at least one optical channel is received at a first network equipment. The optical transport network signal (OTM) is processed to extract optical data units (ODUk) for each optical channel (OCh). There is detection for defects during the processing. The optical data units are retransmitted within optical transport units (OTUk) towards a second network equipment. When a defect has been detected, the retransmitting comprises inserting an optical channel transport unit alarm indication signal (OTUk-AIS) in an optical channel transport unit (OTUk) containing optical channel data units (ODUk) that are affected by the detected defect. The second network equipment detects for the presence of the optical channel transport unit alarm indication signal (OTUk-AIS) and generation of an alarm is inhibited for any optical channel data units (ODUk) contained within the optical channel transport unit that comprises the optical channel transport unit alarm indication signal (OTUk-AIS). The network equipments can comprise a WDM or DWDM equipment and a cross-connect.

摘要： A method distributes clock synchronization information within an optical communications network having a plurality of network elements. The method receives an ingress clock synchronization message at a first network element. The ingress clock synchronization message includes a clock synchronization message identifier and a correction field. The clock synchronization message identifier is inserted into an optical channel frame overhead and the ingress clock synchronization message is inserted into an optical channel frame payload. The optical channel frame overhead and the optical channel frame payload are transmitted across the first network element, across the network to a second network element, and across the second network element. A transit time of the clock synchronization message identifier is determined across each of the network elements. At the second network element, the correction field of the ingress clock synchronization message is updated with the transit times to form an egress clock synchronization message.

摘要： A node for a communications network has a converter for digitizing at a receiver clock rate a received optical signal received over an optical link from an optical transmitter at a source node, a framer for detecting frames and a forward error correction part for correcting errors in the payload of the frame. An error rate in the received payload part is monitored and a processor sends, according to the monitored error rate, a request to the optical transmitter to adapt a length of the transmitted forward error correction part and to adapt a clock rate of the transmission of the frame if FEC length is reduced or FEC is disabled. This can enable power saving, when less FEC information is being sent.

摘要： A method for adapting the rates of a certain number of asynchronous HDLC channels (15) to a single clock domain suited for interfacing with an HDLC processor (13) through a synchronous pseudo-TDM interface (14) in which the HDLC channels are multiplexed in time and vice versa in the opposite direction. In one direction the algorithm is based on the writing of the HDLC channels in a dedicated buffer (17) and in reading these buffers with a common synchronous clock just above the expected maximum HDLC rate. The under-run condition is avoided by inserting neutral information between the end byte and the start byte of the HDLC packets when this is suggested by the buffer fill monitoring function. A simple function to locate the first and last bytes of each HDLC packet read by the buffer is hence used in combination with the buffer fill monitoring function. The algorithm is also suited in the opposite direction in which different asynchronous physical lines receive their HDLC channels from a synchronous TDM-type interface on condition that this interface clock domain be just below the minimum expected HDLC output rate. In this case also the under-run conditions are avoided by insertion of neutral data after having used the same algorithm described above. Adaptation devices and a telecommunications card using them are also proposed.
