Description

A multi-wireless ad hoc network method based on an intelligent routing device

technical field

The present invention relates to the field of communication technology, in particular, to a multi-wireless ad hoc network method based on an intelligent routing device.

Background technique

In LAN communication, the network loop is divided into the switching loop of the two-layer network and the routing loop of the three-layer network. Layer 2 loops are closed loops within or between switches, which can cause abnormal problems such as network storms. Layer 3 loops are generally caused by improper routing settings leading to wrong routing exits, and eventually appear as network loops with TTL (Time to live). Although the network storm caused by Layer 3 loops can disappear by itself, it will still increase greatly. communication overhead. If the two types of loops occur in a network with limited bandwidth resources such as wireless ad hoc networks, it is very easy to cause the exhaustion of device resources in the network and lead to network paralysis.

At present, the solution to the Layer 2 loop is generally to enable the Spanning Tree Protocol (STP, SpanningTree Protocol) of the switch, which determines the topology of the current network by exchanging special protocol packets in real time. When a network loop occurs, STP simply blocks a specific channel in the loop to realize loop removal. Although STP can solve the physical loop problem caused by the introduction of redundant links to maintain network robustness, it still has problems such as slow topology convergence time, inability to implement load balancing functions, and resource consumption caused by topology information exchange in wireless networks.

Detailed ways

In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described here. Therefore, the protection scope of the present invention is not limited by the specific details disclosed below. EXAMPLE LIMITATIONS.

Some embodiments of the present application provide an intelligent routing device.

The intelligent routing device is deployed in the wireless loop, and the number of network ports of the device can be expanded according to usage scenarios. While ensuring the unobstructed loop, the device records in real time the source and destination address information of ARP packets that appear on each network port of the device when all devices in the network are powered on for the first time. After intelligent analysis inside the device, it generates and Maintain an exclusive whitelist. All data forwarded by the device will undergo whitelist verification to ensure that the data is sent through the correct interface, thereby preventing network storms caused by invalid data forwarding; for traffic scenarios with redundant links, the device simultaneously calculates and maintains each wireless network The communication cost values of all nodes in the device are sent with reference to a link with a smaller cost value after the device receives the data packet. The intelligent routing devices only need to regularly exchange information such as the white list of the local address, as a reference for the peer to modify the white list, the amount of data is extremely small, and almost no wireless resources are occupied.

Specifically, as shown in FIG. 1 , the intelligent routing device uses a CPU as a core, and is equipped with multiple network interfaces as external data interfaces according to usage requirements. Among them, one network port is connected to the local device, and the remaining network ports are connected to the self-organizing network device, as shown in Figure 1.

Based on the above intelligent routing device, the present invention also provides a multi-wireless ad hoc network method. There are multiple intelligent routing devices, one of which is used as a local routing device, and the rest are used as peer routing devices. Wherein, as shown in FIGS. 2 to 9 , the local intelligent routing device is referred to as device A for short, and the remote intelligent routing device is referred to as device B for short.

The multi-wireless ad hoc network method includes two parts: network port whitelist addition and data forwarding.

1. The white list includes three categories: local device white list, ad hoc network device white list, and peer device white list. The peer device refers to the local device connected to the intelligent routing device at the other end of the loop. The whitelist addition process is shown in Figure 2.

1) Local device whitelist: After the local device is turned on, the ARP packet is sent to network port 3 of device A, and the CPU captures and analyzes the source IP address of the ARP packet (referred to as the source address), and adds it to the whitelist of network port 3 . The white list of network port 3 is added according to this rule.

2) White list of self-organizing network equipment: After the self-organizing network equipment is connected to the self-organizing network 1(2), it sends an ARP packet to the network port 1(2) of the corresponding device A, and the CPU captures and analyzes the source IP address of the ARP packet, and saves it to Add it to the whitelist of network port 1(2). The white list of Ad hoc network 1(2) is added according to this rule.

3) Peer device whitelist: The local device connected to device B sends an ARP packet to network port 3 of device B after it is powered on. The device B sends the ARP packet to the two wireless ad hoc networks 1 and 2 through its network ports 1 and 2 at the same time, and finally reaches the network ports 1 and 2 of the device A. Because the delays of the two wireless networks are inconsistent and both are at the millisecond level, the arrival time of ARP packets with the same source IP address at network ports 1 and 2 is inconsistent and the difference is small. According to this feature, the source IP address of the ARP packet will be recorded to the peer device whitelist of device A. Then device A forwards the ARP packet to network port 3. The white list of the peer device is added according to this rule.

2. The data forwarding rules are divided into the forwarding rules of the network port 3 connected to the local device and the forwarding rules of the network ports 1 and 2 connected to the ad hoc network equipment. Data outside the rules are not forwarded, and the forwarding rules of the network port 3 will affect For load balancing between two ad hoc networks, it is necessary to calculate the communication cost. Device A will regularly access the topology information data stored in the two connected ad hoc networks, and according to the communication quality of all links of the two wireless networks, calculate the communication cost between any two nodes in real time and store them in the ad hoc network 1, respectively. 2 in the communication cost value matrix.

1. Network port 3 forwarding rules: After network port 3 receives the data packet, it will capture and analyze the packet. If the destination address of the data packet is an address in the white list of network port 1(2), it will be sent from network port 1(2); If the address is an address in the white list of the peer device, query the cost of communication between the two ad hoc networks, and choose the one with the lower cost to send out; the data packet is an ARP packet, for example, the source address is an address in the white list of network port 3 , then the data packets are sent out from network ports 1 and 2.

2. Network port 1(2) forwarding rules: Network port 1(2) performs packet capture and analysis after receiving the data packet. If the destination address of the data packet is an address in the white list of network port 3, it will be sent from network port 3; If the address is an address in the white list of network port 2(1), it will be sent from network port 2(1); if the destination address is the address of network port 1(2), and the source address is an address in the white list of the peer device, then Replace the destination address of the data packet with the real source address attached to the data packet, and send the data packet from the 2(1) network port; the data packet is an ARP packet, such as the source address is in the white list of network port 1(2) address, the data packets are sent from network ports 2(1) and 3.

The intelligent routing devices in the loop maintain the white list information required for their work according to the above rules, and forward according to the forwarding rules of their respective network ports, and do not forward the data packets that do not meet the forwarding rules, so as to avoid network storms caused by invalid data forwarding . The two intelligent routing devices regularly exchange their own whitelist information and network port related information to ensure that the information of both parties is synchronized and prevent the wireless ad hoc network from causing misjudgment by the intelligent routing device.

Referring to the accompanying drawings, the multi-wireless ad hoc network method based on the intelligent routing device in some embodiments of the present invention will be described through some specific embodiments.

Taking the loop composed of two ad hoc networks as an example, the connection relationship is shown in Figure 5. The wireless ad hoc networks C, D and the intelligent routing devices A and B form a central loop network. The wireless ad hoc networks are respectively connected to wireless user equipment in their respective networks, and the third network port of the intelligent routing device is connected to multiple local devices through a switch.

Take the intelligent routing device A as an example to analyze the working mode of the present invention below:

Example 1

As shown in Figure 5, the local devices (A1～AN) send out ARP packets after starting up, and reach the network port 3 of the intelligent routing device A through the switch A. At this time, the source IP address of the ARP packet is recorded in the white list of the network port 3 . Then the intelligent routing device A forwards the ARP packet to the network port 1 and the network port 2 at the same time, and enters the ad hoc networks C and D respectively. The white list of network port 3 is added according to this rule.

Example 2

As shown in Figure 5, the device in the ad hoc network C(D) sends out an ARP packet after it is turned on, and reaches the network port 1(2) of the intelligent routing device A through the wireless network C(D). At this time, the source IP address of the ARP packet is Record it in the white list corresponding to network port 1(2). Then the intelligent routing device A forwards the ARP packet to the network ports 2(1) and 3, and enters the ad hoc network D(C) and the local network A respectively. At this time, the network port 2 (1) of the intelligent routing device B will receive the ARP packet. Because the ARP packet does not meet the forwarding rules (the source address belongs to the address in the white list of the network port 1 (2)), it will not forward it, thus opening The invalid loop is broken. The whitelists of network ports 1 and 2 are added according to this rule.

Example 3

As shown in Figure 5, after the device in the local network B is powered on, it sends an ARP packet, which is sent to the wireless networks C and D through the switch and the intelligent routing device B at the same time, and finally reaches the network ports 1 and 2 of the intelligent routing device A. Because the delays of the two wireless networks are inconsistent and both are at the millisecond level, the arrival time of ARP packets with the same source IP address at network ports 1 and 2 is inconsistent and the difference is small. This ARP packet conforms to the screening feature of the peer device whitelist, so its source IP address is recorded in the peer device whitelist of the intelligent routing device A. Then the intelligent routing device A forwards the ARP packet to the network port 3 . The white list of peer devices belonging to intelligent routing device A is added according to this rule.

Example 4

As shown in Figure 5, intelligent routing A regularly accesses the wireless ad hoc network construction information data existing in the ad hoc network C0 and D0 equipment, and calculates the communication between any two nodes in real time according to the communication quality of all links of the two networks The cost value is stored in the cost value matrix of the ad hoc network C and D respectively.

In addition, after the two intelligent routing devices complete the information analysis and recording required for their own work according to the above-mentioned working method, the network enters the normal communication stage. The following analyzes the process of data starting from different starting points and reaching the destination according to the forwarding rules:

Example 5

As shown in Figure 6, the local device A1 sends data to the ad hoc network device C1 (send to device D1 in the same way)

The local device A1 uses its own IP address as the source address and the address of the ad hoc network device C1 as the destination address to package and send the data to the switch A. After the data arrives at network port 3 of intelligent routing device A, the two IP address information in the data packet are analyzed, and it is resolved that the source address of the data packet belongs to the white list of network port 3, and the destination address belongs to the white list of network port 1, which conforms to the forwarding rules. At this time, intelligent routing device A queries through both sides of the loop (route A: intelligent routing device A->ad hoc network C0->ad hoc network C1, route B: intelligent routing device A->ad hoc network D0->intelligent routing device B->Ad hoc network C1) communication cost value, if the cost value of line A is smaller, it will be sent from network port 1, and finally reach the ad hoc network device C1. If the cost value of line B is smaller, replace the destination IP address in the data packet with the IP address of network port 2 of the intelligent routing device B. The source and destination addresses are added to the data packet and sent to the intelligent routing device B through the ad hoc network D. After the intelligent routing device B network port 2 receives the data packet, it resolves that the source address of the data packet belongs to the white list of the peer device, and the destination address is the IP of the network port, then restores the destination address of the data packet to the original state, removes the additional bits and then starts from The network port 1 sends out, and finally reaches the ad hoc network device C1.

Example 6

As shown in FIG. 7 , the local device A1 uses its own IP address as the source address and the address of the ad hoc network device A1 as the destination address to send the data to the switch A in packets. After the data arrives at network port 3 of intelligent routing device A, the two IP address information in the data packet are analyzed, and it is resolved that the source address of the data packet belongs to the white list of network port 3, and the destination address belongs to the white list of the peer device, which conforms to the forwarding rules. At this time, intelligent routing device A queries through both sides of the loop (route A: intelligent routing device A->ad hoc network C0->ad hoc network C->intelligent routing device B->local device B1, route B: intelligent routing device A ->Ad hoc network D0->Ad hoc network D->Intelligent routing device B->Local equipment B1) The communication cost value of the wireless transmission part, if the cost value of line A is smaller, it will be sent from network port 1, and the cost value of line B If it is smaller, it is sent from the network port 2, and finally reaches the local device B1.

Example 7

As shown in FIG. 8, the ad hoc network device C1 sends data to the local device A1.

The ad hoc network device C1 uses its own IP address as the source address and the local device A1 address as the destination address to package the data and send it to the network port 1 of the intelligent routing device A through the ad hoc network C. The intelligent routing device A resolves that the source address of the data packet belongs to the white list of network port 1, and the destination address belongs to the white list of network port 3, which conforms to the forwarding rules, and sends the data packet from network port 3 to the local device A1. Due to the limitation of the working mode of the ad hoc network, the data packet of the ad hoc network device C1 will only be sent to the ad hoc network device C0, so there is only one route for such data forwarding.

Example 8

As shown in FIG. 9 , the ad hoc network device C1 sends data to the ad hoc network device D1.

The ad hoc network device C1 uses its own IP address as the source address and the ad hoc network device D1 address as the destination address to package the data and send it to the network port 1 of the intelligent routing device A through the ad hoc network C. The intelligent routing device A resolves that the source address of the data packet belongs to the white list of network port 1, and the destination address belongs to the white list of network port 2, which conforms to the forwarding rules, and sends the data packet from network port 2 to the ad hoc network device D1. Due to the limitation of the working mode of the ad hoc network, the data packet of the ad hoc network device C1 will only be sent to the ad hoc network device C0 (or C_0), so there is only one route for such data forwarding.

To sum up, in view of the application characteristics of wireless ad hoc network communication, the present invention forwards data to the destination device according to the path with the least cost by analyzing the network topology and wireless network load in real time, so as to realize load balancing and fast topology between two wireless networks. convergence.
