Embodiments of the present application provide a message sending method, device, storage medium and node equipment, and relate to the technical field of communications. The method includes: obtaining service information; according to the corresponding relationship between the priority mark and the forwarding delay of the SR forwarding tunnel, obtaining the tunnel identifier of the SR forwarding tunnel corresponding to the priority mark; encapsulating the tunnel identifier in the service information to obtain the SR tunnel message; send the SR tunnel message to other node devices. According to the corresponding relationship between the priority mark and the forwarding delay of the SR forwarding tunnel, the tunnel identifier of the SR forwarding tunnel corresponding to the priority mark is obtained, that is to say, when the priority mark of the service information is high, it can Corresponding the tunnel ID of the SR forwarding tunnel with low forwarding delay to its priority mark, so that the service information is forwarded through the SR tunnel with low forwarding delay, so this application can shorten the forwarding time of important messages and improve the Forwarding efficiency.

The embodiment of the invention provides a data package forwarding method and device. The method includes the steps that when a mobile node is switched to a destination node from a source node, a second node receives a data package which is from a first node and is sent to the mobile node, the data package is sent to the second node under the condition that the first node detects that the data package cannot be successfully sent to the mobile node, and the first node is used as the source node or the first node receives the data package from the source node; the second node sends the data package to the mobile node; if the second node detects that the data package cannot be successfully sent to the mobile node, the data package is sent to a third node, and accordingly the third node can send the data package to the mobile node. By means of the data package forwarding method and device, the forwarding time of the data package is shortened.

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 discloses a forwarding method and system of an AH message, so as to solve the problem that in the forwarding process of the AH message, it is first necessary to search for PSEC SA and decapsulate the AH message, then search for a fast forwarding table and perform two steps of secondary matching and forwarding Instead, the AH message forwarding time cannot be effectively shortened. The forwarding method comprises: after receiving the AH message, searching whether the fast forwarding table corresponding to the current AH message exists; if it exists, processing and forwarding the current AH message according to the fast forwarding table; if not, A fast forwarding table is created according to the current AH message, and the current AH message is processed and forwarded accordingly. Through the creation of the fast forwarding table, other AH messages corresponding to the AH messages created in the fast forwarding table are directly processed accordingly, thereby eliminating the process of repeated search or secondary matching, and effectively shortening the time required for the AH message. forwarding time.

The present invention provides a message forwarding method and device, so that when an AP in a MESH network receives a data message, it first judges whether the data message carries label forwarding information, and if so, when the destination forwarding label is not the label of the AP , find the destination AP corresponding to the destination forwarding label, and forward the message to the destination AP; when the destination forwarding label is the label of this AP, remove the label forwarding information of the message, according to the The destination MAC address of the message is searched for the MAC address entry for forwarding; if not, it is judged whether the outbound interface of the data message is a MESHLINK port; if yes, the label forwarding information is added to the message and forwarded to the next Hop to AP; if not, forward according to MAC address entry. Therefore, the present invention can prevent each hop AP from performing guidance and forwarding by looking up MAC forwarding table items.
