The invention discloses an Ethernet-oriented adaptive dynamic flow control system and method, belonging to the technical field of data communication. Ethernet MAC module, the 40G Ethernet MAC module is connected to the peer network device; the checksum generation module includes a UDP protocol packet header encapsulation module, an IP protocol packet header encapsulation module and a ping-pong cache FIFO, which are connected in sequence, and a ping-pong cache FIFO and a transmission control module connect. By adopting the state monitoring algorithm and flow control method, the frame length and frame interval of the transmitted data are automatically determined, and the filling process of the transmitted data is adaptively started, paused, and terminated, so as to maximize the utilization of the transmission bandwidth of 40G Ethernet.

Embodiments of the present invention provide a data forwarding method and device based on node social similarity and individual centrality. The method is applied to the Internet of Things, and the Internet of Things includes multiple mobile nodes; the method includes: the current mobile node uses the law of universal gravitation to determine the next-hop mobile node; the individual centrality values ​​of the current mobile node and the next-hop mobile node represent respectively The quality in the law of gravity; the social similarity value between the current mobile node and the next-hop mobile node represents the distance in the law of gravity; the individual centrality value and the social similarity value are based on the distance between the current mobile node and the next-hop mobile node The encounter frequency and proximity are determined; the current mobile node transmits the data to be forwarded to the next-hop mobile node. Therefore, the embodiment of the present invention improves the data forwarding performance, so that the Internet of Things has the effects of high data delivery rate, low delay, less average hops in message delivery, low message delivery failure rate, and low energy consumption in the application.

The invention discloses a method for distributing and updating routing information in an SD-WAN network and a controller, relating to the field of controllers and routing, including collecting routing information after the SD-WAN controller is connected to the SD-WAN network, and converting the entire network The routing information, the routing information sent to the device, and the routing information associated with the network are stored separately; when the user establishes a service, the controller sends part of the routing information to the associated device as needed according to the network identifier and routing prefix, and stores the information of the network and the device. corresponding relationship, and refresh the mapping relationship between routing information and network. In the method for distributing and updating routing information in the SD-WAN network of the present invention, the SD-WAN controller serves as the control plane to establish a connection with the device, centrally manage the device, collect the routing information of the SD-WAN network and update it in time, so that the device is only responsible for forwarding, Improve data forwarding performance.

The invention relates to a method for realizing network address translation. This method is to reasonably divide the various tasks required for network address translation, and complete them respectively by CPRC and SDP in the C5 network processor, that is, to determine the address information that needs to be converted in the message and the calculation needs in the CPRC module. The difference value of the converted address information, and look up the table to determine the converted address information. In the SDP module, the calculation of the checksum value of the converted address information of the message, the conversion of the address information of the message, and the report The text is forwarded. The invention can improve the efficiency of network address translation, and provides a basis for wire-speed forwarding of messages based on network address translation in a network communication system.

The invention discloses a method for realizing split horizon. An entry sub-module of distribution-typed network equipment in the core network sends the entry attributes and the content of an unknown address data packet to a forwarding matrix sub-module of the distribution-typed network equipment, and the unknown address data packet is a data packet which is received from the interface connected with the equipment of other core networks; after the forwarding matrix sub-module receives the entry attributes and the content of the unknown address data packet, the entry attributes of the unknown address data packet is compared with the exit attributes of an exit sub-module of the distribution-typed network equipment, if the attributes are same, the content of the unknown address data packet is not forwarded to the exit sub-module; otherwise, the content of the unknown address data packet is forwarded to the exit sub-module. The invention reduces the times that the forwarding matrix sub-module copies and forwards the unknown address data packet and improves the data processing capability of the forwarding matrix sub-module.

The embodiment of the invention provides a data forwarding method and device based on an articulated naturality web. The method comprises steps of creating a plurality of virtual articulated naturality web terminals in the physical articulated naturality web server, receiving articulated naturality web conference data sent by the articulated naturality web devices in the first articulated naturality web device cluster by using the virtual articulated naturality web terminals, and sending the articulated naturality web conference data to the articulated naturality web devices in the second articulated naturality web device cluster by using the virtual articulated naturality web terminals, wherein the data forwarding performance of the virtual articulated naturality web terminal is higher than or equal to the data forwarding performance of the physical terminal, the sum of the data forwarding performance of the plurality of virtual articulated naturality web terminals is higher than thedata forwarding performance of one physical terminal. Therefore, if the data size of the Internet of Things conference data needing to be interacted between the Internet of Things equipment of the first Internet of Things equipment cluster and the Internet of Things equipment of the second Internet of Things equipment cluster is very large, a plurality of virtual articulated naturality web terminals can quickly forward a large amount of articulated naturality web conference data, so that the articulated naturality web conference can be smoothly carried out.

The invention discloses a method for distributing and updating routing information in an SD-WAN network and a controller, and relates to the field of controllers and routing.The method comprises the steps that after the SD-WAN controller accesses the SD-WAN network, the routing information is collected, and the routing information of the whole network, the routing information issued to equipment and the routing information associated with the network are stored respectively; and when a user establishes a service, the controller issues a part of routing information to the associated equipment as required according to the network identifier and the routing prefix, stores the corresponding relationship between the network and the equipment, and refreshes the mapping relationship between the routing information and the network. According to the method for distributing and updating the routing information in the SD-WAN network, the SD-WAN controller serves as a control plane to establish connection with the equipment, the equipment is managed in a centralized mode, the routing information of the SD-WAN network is collected and updated in time, the equipment is only responsible for forwarding, and the data forwarding performance is improved.
