The disclosure discloses a method for realizing hot backup in a centralized network node, in which a main control module and a standby control module are arranged, including: an Resource Reservation Protocol-Traffic Engineering (RSVP-TE) tunnel, which contains two Label Switched Paths (LSPs): a main LSP and a standby LSP, is established for services; and further including: the main control module acquires control information of the main LSP and that of the standby LSP, sets identification information of the control information of the main LSP and that of the standby LSP as Active or Inactive according to the current statuses of the main and standby LSPs, and synchronizes the control information of the main LSP and that of the standby LSP to the standby control module; and the current main control module generates forwarding information according to the control information of the LSP whose identification information is Active, and forwards a service after the switching between the main and standby control modules. The disclosure further discloses a system for realizing the method. The disclosure reduces the switching time and the forwarding time, and improves the service forwarding speed.

Disclosed are a physical-port control method and apparatus. The method comprises: monitoring a change of channel information corresponding to a physical port for a layer-2 service; when it is detected that the channel information changes from complete to incomplete, closing the physical port; and when it is detected that the channel information changes from incomplete to complete, opening the physical port.

The invention provides an uplink bandwidth allocation method based on neural network prediction in a 50G-PON network, comprising: training an LSTM neural network; all ONUs send report messages to the OLT to report the queue length; and the OLT prioritizes the services of the ONUs according to the report messages Divide, and sort all ONUs and report queue lengths according to RTT; allocate all services according to the sorting results and LSTM neural network; calculate and allocate the low-priority services of the last ONU to ensure the end of the polling cycle At the same time, the allocation result is obtained; the OLT packages the allocation result and publishes it to all ONUs; each ONU sends information in turn according to the received allocation result. The uplink bandwidth allocation method adopts the method of neural network prediction, which ensures that the data can be forwarded in time and effectively reduces the transmission delay; at the same time, this scheme takes into account the characteristics of bandwidth and delay requirements of different services, and reasonably allocates the transmission order. , to ensure the quality of network service.

The embodiments of the present application disclose a network configuration deployment method, apparatus and device. The method includes: in the SDN network environment, the SDN controller determines the network device through the management channel; the SDN controller determines the network role of the network device according to the type and characteristics of the network device, and combines different network devices into a network device according to the network role. The corresponding network model; the SDN controller determines the topological connection relationship between network devices in the network model according to the network roles and service ports on the network device, and completes the network planning; Resources are allocated, network resource parameters are determined, the allocated network resource parameters are converted into configuration commands, and the configuration commands are allocated to the network devices, so that the network devices run network protocols through the configuration commands to achieve network connectivity.

Embodiments of the present invention provide a flow rule sending method, a path computation element (PCE), a path computation client (PCC), and a system. The method comprises: a PCE generates a correspondence between path identification information and flow rules; and the PCE sends a path computation element communication protocol (PCEP) message to a PCC, the PCEP message carrying the correspondence between the path identification information and the flow rules, and the flow rules being used for instructing the PCC to forward a traffic matching the flow rules according to the path identification information. The PCE comprises: a processing unit, used for generating a correspondence between path identification information and flow rules; and a sending unit, used for sending a PCEP message to a PCC, the PCEP message carrying the correspondence between the path identification information and the flow rules, and the flow rules being used for instructing the PCC to forward a traffic matching the flow rules according to the path identification information. By means of the technical solution in the embodiments of the present invention, a traffic matching flow rules can be forwarded in time.

The invention discloses a method, a device and a system for requesting data, and relates to the technical field of internets, which aims at solving the problem of paralysis caused by excessive query requests of a database. The method comprises the following steps of establishing a first coroutine corresponding to the database, detecting the load state of the database through the first coroutine, and obtaining the detection result; when an query request reported by a terminal is received, establishing a second coroutine corresponding to the query request, and obtaining the detection result from the first coroutine through the second coroutine; when the detection result represents that the database is in the overload state, stopping forwarding the query request to the database. The method is mainly applied to postgresql database systems.
