Abstract: A frequency allocation method includes receiving, by a control device, a frequency allocation message using a dedicated channel, wherein the frequency allocation message carries a node identifier and a received signal strength information for a frequency, and determining, according to the frequency allocation message, a station needing frequency allocation, and obtaining node information of each station in a network. The method further includes computing, according to the received signal strength information for the frequency of the station needing frequency allocation and further according to the node information of each station, an optimum working frequency of the station needing frequency allocation, and allocating the optimum working frequency to the station needing frequency allocation.

Abstract: The present disclosure discloses a protection switching method and a node. The method includes: receiving, by an intermediate node, a first protection switching request message sent by an upstream neighboring node, where the first protection switching request message is used to request to activate a first protection path, and the intermediate node is a node on the first protection path; determining, by the intermediate node, that the first protection path needs to occupy N1 timeslots, and selecting N1 timeslots for the first protection path from N2 available timeslots in a preset order; and sending, by the intermediate node, a second protection switching request message to the downstream neighboring node, where the second protection switching request message is used to request the downstream neighboring node to complete a cross-connection, on the first protection path, between the downstream neighboring node and the intermediate node based on the first group of timeslots.

Abstract: A method, an apparatus, and a system for sending a control request based on a key value configuration. The method includes generating, by a client controller, a control request, wherein having a plurality of configuration parameters, wherein the plurality of configuration parameters comprise a flexible key value, a control object name, and a universally unique identifier (UUID), where the flexible key value identifies a requested control object, and the flexible key value is determined using at least one of the control object name or the UUID, and sending, by the client controller, the control request to a server controller, where the control request indicates to the server controller to configure the control object.

Abstract: A network node for a Data Communication Network (DCN) and a network device for providing traffic to the DCN are provided. The network node is configured to receive a plurality of packets carrying DCN messages; determine, from the received packets, a first set of packets addressed to other network nodes of the DCN. The network node is then configured to forward the first set of packets over a Time-Division-Multiplexing (TDM) connection, in particular over an Optical Data Unit-k (ODUk) connection, to a determined network node of the DCN. According to the application, a high bandwidth efficiency is maintained, and the number of interfaces to be managed on a controller is reduced.

Abstract: A network analytics engine predicts impairment of one or more communications links included in a current data path being used to transmit data through a network, and transmits information indicating the predicted impairment to a network controller in a warning message. In response to receiving the warning message, the network controller identifies potential alternative data paths that exclude any communication links predicted to experience an impairment. Before setting up an alternative data path, however, the network controller waits for a fault notification confirming the predicted impairment. If the fault notification is received before expiration of a waiting period, the network controller sets up one of the potential alternative data paths in place of the current data path.
