This invention discloses a kind of fast looped network protection method. It concludes: the fast looped network protection area is set up. Nodes are connected with each other through ports to form a loop. Each node is consisted with two ports that are connected with loop; master node sets the first port to retransmission mode and sets the second port to blocking mode; the link trouble is acquired through accessing control table, retransmission table entry or virtual local area network. The said virtual local area network retransmits data messages and protocol messages; when acquiring the link trouble, master node sets the second node to retransmission mode. The retransmission tables of master node and other nodes are refreshed. A special control VLAN aiming at protocol message does not need. Thus, it can save VLAN ID resource of each node.

The embodiment of the invention provides a bullet screen information transmission method and device, a bullet screen information displaying method and device, and an electronic device. The bullet screen information transmission method comprises the steps of when bullet screen information is received, determining a video identifier corresponding to the bullet screen information; determining all long connection links associated with a video corresponding to the video identifier; and sending the bullet screen information through each long connection link. Through utilization of the method, after terminals watching the same live broadcast video at the same time send the bullet screen information to a server, the server can directly send the bullet screen information to the terminals watching the live broadcast video directly through preset long connection links on the server. In the whole process, the server only forwards the bullet screen information and does not process the bullet screen information, so the forwarding time of the bullet screen information is reduced.

The invention relates to an input buffer structure and a data forwarding method of an Ethernet switch, and belongs to the technical field of computer network communication. The cache structure of theinvention includes different storage areas divided according to data frame types, and the storage areas of each data frame type include an address storage module, a data storage module and a verification storage module, wherein the data storage module is used to store the data content of the data frame when a forwarding port is queried according to the destination address in the address storage module. When searching for the relevant forwarding port corresponding to the destination address, the invention caches the data of the corresponding frame into the corresponding data storage module, andfully utilizes the data storage time of the data frame to make the data in the received data frame be processed in parallel with the forwarding port searching the destination address, thereby reducing the search time, shorting the forwarding time of the data frame in the switch, improving the efficiency, and meeting the requirement for the switching delay of time-triggered Ethernet switch.

The embodiment of the invention provides a message sending method and device, a storage medium and node equipment, and relates to the technical field of communication. The method comprises the following steps: acquiring service information; acquiring a tunnel identifier of the SR forwarding tunnel corresponding to the priority mark according to the corresponding relationship between the priority mark and the forwarding delay of the SR forwarding tunnel; encapsulating the tunnel identifier in the service information to obtain an SR tunnel message; and sending the SR tunnel message to other nodeequipment. According to the corresponding relationship between the priority mark and the forwarding delay of the SR forwarding tunnel, the forwarding delay is reduced; obtaining a tunnel identifier of an SR forwarding tunnel corresponding to the priority mark, that is to say, what is to say is to say, when the priority of the priority mark of the service information is high, the tunnel identifierof the SR forwarding tunnel with low forwarding delay can correspond to the priority mark of the SR forwarding tunnel, so that the service information is forwarded through the SR tunnel with low forwarding delay, the forwarding time of important messages can be shortened, and the forwarding efficiency of the messages is improved.

The invention discloses a network data forwarding method and system of a Linux device, and relates to the technical field of Linux network data forwarding. The method comprises the following steps ofdetermining whether a Hash table item corresponding to the received data packet exists in a Hash link list, if yes, forwarding the received data packet, otherwise, keeping the Linux device in the Hashlink list, and forming the Hash table item according to the received data packet; subjecting the received data packet to the CPU processing to form a sending data packet; if the Hash table item corresponding to the data packet information exists in the Hash link list, comparing the header information of the sending data packet with the header information of the data packet in the Hash table itemto obtain the difference header information, and forwarding the sending data packet through a Linux standard network protocol stack after the difference header information is added to the hash table item. On the basis that the data packet is not forwarded relaying on a hardware network accelerator, the probability of data packet loss is reduced, the forwarding time of the data packet is shortened,and the forwarding efficiency of the data packet is improved.

The invention provides a high usage router method applied in an underground wireless network by combining the topographical features of the mine laneways. Firstly the critical angle and the critical distance of the switch between the underground laneway environment power estimation and the router are determined; a sending node selects the optimal next skipping node according to the position information of adjacent nodes, and the sending power is dynamically adjusted according to the judgment of near-wall transmission or in-cave transmission; a receiving node determines the transmission mode selected by the sending node according to the orientation of the sending node and performs corresponding receiving power estimation; once being determinated as the optimal forwarding node, the receiving node compresses the redundant RREQ and preferentially carries out RREQ forwarding process. At the same time, if the established route is interrupted due to the failure of the certain node, a complementary route can be found by the recorded RREQ information to restore the router. The method fully considers the features of the communication environment of the underground laneway, thus being a self-adaptive geographic router method with high robustness.

The invention provides a message forwarding method and apparatus. The method comprises the following steps that firstly, when an AP in the MESH network receives a data message, it first judges whether the data message carries tag forwarding information, If so, the destination AP corresponding to the destination forwarding tag is searched when a destination forwarding tag is not the tag of the AP, and the message is forwarded to the destination AP; when the destination forwarding tag is the tag of the AP, the tag forwarding information of the message is removed, and the MAC address table entry is searched and forwarded according to the destination MAC address of the message; if not, whether the outcoming interface of the data message is the MESHLINK port or not is determined; if yes, the message is added with the tag forwarding information and then forwarded to a next-hop AP; and if not, forwarding is performed according to the MAC address table entry. Therefore, the present invention can prevent each hop AP from guiding the forwarding by looking up the MAC forwarding table entry.
