摘要： Systems and methods are disclosed for configuring a communications network. In disclosed embodiments, a set of permissible service link decompositions and a set of basic service links may be obtained for the communications network. A spanning subset of service links for the communications may be generated. Generation of the spanning subset may include selecting a decomposition of a first service link from a set of permissible service link decompositions; updating the set of permissible service link decompositions based on the selected decomposition; and updating the set of basic service links using the updated set of permissible service link decompositions. In some embodiments, obtaining the set of permissible service link decompositions can include generating a set of permissible service link decompositions by traversing decomposition graphs generated for each of the service links. In some embodiments, the communications network can be configured to satisfy network demands using the spanning subset.

摘要： A method and system are provided for connecting at least three provider peer elements PEs located in two L2 network sites, via a provider network, wherein at least in one of the L2 sites and two of the provider peer elements PEs are connected to a customer equipment CE forming together a dual homing structure. The method and system are characterized in that they rely on the use of only a single PW in the provider network that extends between PEs of the two L2 network sites while ensuring traffic protection for the PW in the provider network, and ensuring that in case of a failure of one of the PEs or its connection to the customer equipment at one of the sites, the other L2 network site remains unaware of the failure, so that once established, traffic communication over the PW is maintained like no failure has happened.

摘要： A method is provided for synchronizing binary data transmitted in parallel via N channels. The method comprises performing at the receiver side, a data-clock-alignment for the data in the N channels by selecting an optimal reference channel to which no delay will be added, and adding an appropriate delay to each of the remaining channels, until their respective centers of valid data portions are aligned to each other, and associating clock edges with the centers of the valid data portions. The method is characterized in that the alignment is performed regardless to whether binary word alignment is simultaneously achieved or not, and wherein the optimal reference channel allows aligning the centers of valid data of all the channels while adding a minimal delay to a worst channel from among the remaining channels, wherein the worst channel carries valid data portions which are maximally shifted from those of the reference channel.

摘要： A method is proposed for improving protection of data traffic in an optical ring network, where the data is arranged in SDH/SONET frames and the network supports a standardized MS-SPRING/BLSR protocol. The method comprises providing means to distinguish between a first kind and a second kind of coded protocol messages. The first kind of the messages is a bridge request message sent from node P (a first node) to node Q (a second node) and signaling about a unidirectional signal failure or degradation between the node P and Q, and the second kind of the messages is an acknowledgement message sent from node Q to node P in response to the bridge request message.
