Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments. It should be noted that "first" and "second" are used only for distinction and do not indicate a sequential order.
Example one
The embodiment of the invention provides a multi-device data transmission method. Fig. 2 is a flowchart of a multi-device data transmission method according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S202, the main network access device obtains the operation condition of the current network;
step S204, the main network access device judges whether to transmit data through the auxiliary network access device according to the operation condition;
step S206, if the determination result is yes, the main network access device sends the data stream to the auxiliary network access device according to a preset rule, and performs data transmission through the auxiliary network access device.
By the method, the main network access device distributes the data stream to the auxiliary network access device, receives the message from the auxiliary network access device and forwards the message to the local area network LAN side device, and the auxiliary network access device can take over the role of sharing part of data transmission service for the main network access device, so that the function of expanding the network bandwidth is achieved, and the household LAN side device cannot sense the existence of a plurality of network access devices.
Further, the determining, by the main network access device, whether to transmit data through the auxiliary network access device according to the operating condition includes: comparing the uplink bandwidth utilization rate of the current network with a first minimum threshold value and/or comparing the Central Processing Unit (CPU) utilization rate with a second minimum threshold value; and judging whether the uplink bandwidth utilization rate is greater than the first minimum threshold or whether the CPU utilization rate is greater than the second minimum threshold.
The method determines whether to adopt the auxiliary network access equipment to send the data stream by judging the operating conditions of the current network. The operation conditions of the network include, but are not limited to, two standards of bandwidth utilization rate and CPU utilization rate, and can be adaptively adjusted according to actual needs. It can be seen that the auxiliary network access device will operate as long as any one of the operating conditions reaches a preset minimum threshold.
Further, the sending the data stream to the auxiliary network access device according to the preset rule includes: when the uplink bandwidth utilization rate is greater than the first minimum threshold, less than the first minimum threshold and the CPU utilization rate is less than the second maximum threshold, or the CPU utilization rate is greater than the second minimum threshold, less than the second maximum threshold and the uplink bandwidth utilization rate is less than the first maximum threshold, sending the data stream to the auxiliary network access device in a first preset proportion; and sending the data stream to the auxiliary network access equipment according to a second preset proportion under the condition that the uplink bandwidth utilization rate is greater than the first maximum threshold value or the CPU utilization rate is greater than the second maximum threshold value.
It should be noted that the first minimum threshold, the second maximum threshold, the first preset ratio, and the second preset ratio may be freely configured according to actual needs. Further, normally, the second predetermined ratio should be greater than the first predetermined ratio. However, the case where the second predetermined ratio is less than or equal to the first predetermined ratio is not excluded.
Further, the sending the data stream to the auxiliary network access device according to the preset rule may further include the following method: searching a characteristic entry corresponding to the data flow from a connection tracking record table, wherein the characteristic entry comprises a source IP address, a destination IP address, a source port, a destination port and a protocol type; and sending the data stream of which the feature item is not found to the auxiliary network access equipment according to the preset rule.
When the data stream requested by the user terminal on the LAN side reaches the main network access device, the main network access device first searches the connection tracking record table. A network access device, such as a gateway, implements a state firewall, where a connection tracking record table is provided to record information and state of each connection, and each connection generally includes at least information of a source IP, a destination IP, a protocol, a destination port, and a source port. More information may be included in general, such as information in both the direction of initiation and the direction of response. Whether the connection of the current data flow is an existing connection or a new connection can be judged by searching the connection tracking record table. If the connection information corresponding to the current data stream is found, the connection is indicated to be an existing connection, and the main network access device still processes the connection. The main network access device continues to process the original connection, so that the time for searching the route can be saved.
Further, the sending the data stream for which the feature entry is not found to the auxiliary network access device according to the preset rule includes: when the uplink bandwidth utilization rate is greater than a first minimum threshold, less than a first maximum threshold and the CPU utilization rate of the central processing unit is less than a second maximum threshold, or the CPU utilization rate is greater than a second minimum threshold, less than the second maximum threshold and the uplink bandwidth utilization rate is less than the first maximum threshold, sending the data stream for which the feature entry is not found to the auxiliary network access device according to a third preset proportion; and sending the data stream of which the feature entry is not found to the auxiliary network access equipment according to a fourth preset proportion under the condition that the uplink bandwidth utilization rate is greater than the first maximum threshold or the CPU utilization rate is greater than the second maximum threshold.
The data stream corresponding to the feature entry not found can be marked with a mark, and then the routing table is found according to the mark value and sent to the auxiliary network access equipment according to the rule.
It should be noted that the third preset proportion and the fourth preset proportion may be freely configured according to actual needs. For example, the third predetermined proportion is 80% and the fourth predetermined proportion is 100%. Further, normally, the fourth predetermined ratio should be greater than the third predetermined ratio. However, the case where the fourth predetermined ratio is less than or equal to the third predetermined ratio is not excluded. It should be noted that the numerical values of the third preset ratio and the fourth preset ratio are not necessarily related to the numerical values of the first preset ratio and the second preset ratio, and the case that the fourth preset ratio is equal to the first preset ratio or the second preset ratio and the third preset ratio is equal to the first preset ratio or the second preset ratio is not excluded.
Further, before obtaining the operation condition of the current network, the method further includes: carrying out identity verification on the access equipment; and configuring the routing information for connecting the auxiliary network access equipment under the condition that the access equipment is the auxiliary network access equipment.
Configuring the routing information for connecting the auxiliary network access device herein refers to configuring the routing information between the main network access device and the auxiliary network access device. After the routing information is configured, the data transmission can be carried out between the main network access equipment and the auxiliary network access equipment. Of course, when the auxiliary network access device goes offline, the record information such as the configured route entry needs to be deleted.
Further, the identity verification of the access device includes: sending a detection message to the access device, wherein a destination Media Access Control (MAC) address of the detection message is an MAC address of the access device, and a destination IP address and a source IP address of the detection message are addresses of different network segments; under the condition that the host redirection message is not received, determining the access equipment as auxiliary network access equipment; and under the condition of receiving the host redirection message, determining the access equipment as the user equipment.
The main network access device sends a detection message to the tested device, the destination MAC of the message is the MAC of the tested device, the destination IP of the message is an address of a network segment different from the IP address of the main network access device, and the message can be an actually existing IP address, such as a hundred-degree IP, or a virtual address. The message protocol may be a network control message protocol ICMP or a user datagram protocol UDP. If receiving ICMP message redirected by user, it shows that the tested device is LAN side common user device of main network access device, and it needs to access network by network access device; and conversely, the tested device is the auxiliary network access device.
The situation that the host redirection message is not received comprises the following steps: 1) Receiving an ICMP message which is inaccessible to the network, and indicating that the WAN connection configuration of the auxiliary network access equipment is wrong; 2) If no message is received, it indicates that the auxiliary network access device may successfully send out the detection message, or may not successfully send out the message, or the destination IP is an address that does not exist. Therefore, a diagnostic method using an Internet Packet explorer (ping) is required to further check whether the network is connected.
Further, after determining that the access device is an auxiliary network access device, the method further includes: sending a network control information protocol ICMP request message to a server through the auxiliary network access equipment; under the condition of receiving the corresponding ICMP response message, determining that the network connection state corresponding to the auxiliary network access equipment is normal; and under the condition that the corresponding ICMP response message is not received, determining that the network connection state corresponding to the auxiliary network access equipment is abnormal. At this time, the destination MAC of the ICMP request message is the MAC of the device under test, and the destination IP of the message is the address of a network segment different from the IP address of the main network access device, and must be an actually existing IP address.
Of course, before sending the ICMP request message, the main network access device may first determine whether the ICMP message that is inaccessible to the network is received, and if the ICMP message that is inaccessible to the network is received, it may directly determine that the network connection state corresponding to the auxiliary network access device is abnormal, and naturally, subsequent sending of the ICMP request message is not required.
The identity verification of the access device and the verification of the network connection condition of the auxiliary network access device can be carried out simultaneously by using the ICMP request message as a detection message for sending. At this time, the main network access device may determine whether the access device is an auxiliary network access device at one time, and how the network condition of the auxiliary network access device is: 1) Receiving ICMP message redirected by user, which shows that the tested device is LAN side common user device of main network access device; 2) Receiving an ICMP message which is inaccessible to the network, and indicating that the tested equipment is auxiliary network access equipment and the WAN connection configuration is wrong; 3) Under the condition of receiving the ICMP response message, the detected equipment is the auxiliary network access equipment, and the network connection state corresponding to the auxiliary network access equipment is normal; 4) And if no message is received, the tested device is the auxiliary network access device, and the network connection state corresponding to the auxiliary network access device is abnormal.
It should be noted that before the auxiliary network access device accesses the main network access device, a Dynamic Host Configuration Protocol (DHCP) service function of the auxiliary network access device should be closed, and an IP address of the auxiliary network access device should be configured to be in the same network segment as that of the main network access device. For example, the LAN side segment of the main network access device is 192.168.1.1/24, the address of the auxiliary network access device is 192.168.1.254. In addition, the wide area network WAN connection of the auxiliary network access device is configured to be able to dial-up successfully to access the network. The main and auxiliary network access devices can be connected by a network cable through an Ethernet interface on the LAN side.
