Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Various devices in the household generally access the network through a router, but the wireless coverage of the router is limited, so the coverage of the router signal can be extended through a wireless relay device (Repeater). The wireless relay equipment can be used as a wireless access point to play a role in relaying in network connection, and can realize relay and amplification of router signals, so that the coverage range of a wireless network is extended.
However, the existing wireless relay device is usually only wirelessly connected to an uplink router, and therefore, when the router connected to the wireless relay device has poor signals or the router is damaged, it is not guaranteed that the device side always maintains good network signals.
Based on the above analysis, the inventor proposes a data transmission system, please refer to fig. 1, where fig. 1 is a schematic diagram of a data transmission system according to an embodiment of the present application, and the data transmission system 100 may include: a wireless relay device 101, a plurality of device peers 102, and a plurality of routers 103. Fig. 1 only shows one device end 102 and three routers 103, it can be understood that fig. 1 is only an example provided in the embodiment of the present application, and the number of the device ends 102 and the routers 103 is not specifically limited in the embodiment of the present application, and those skilled in the art may make appropriate adjustments according to actual situations.
In the data transmission system provided in the embodiment of the present application, the device end 102 may directly perform data transmission with the router 103, and when the device end 102 is not within a range capable of receiving a signal of the router 103, the device end 102 may perform data transmission with the router 103 through the wireless relay device 101.
As shown in fig. 1, the device side 102 is out of the signal range of the three routers 103, and at this time, the device side 102 cannot perform data transmission with any router 103 in the three routers 103. Thus, by the wireless relay apparatus 101 disposed in the middle of the three routers 103, the signal ranges of the three routers 103 can be expanded respectively, so that the apparatus side 102 can perform data transmission with the three routers 103 respectively under different situations. The wireless relay device 101 may be wirelessly connected to the plurality of routers 103 (for example, the connection mode includes WIFI 5G connection, WIFI 2.4G connection, wired ethernet connection, and the like), but the wireless relay device 101 only selects one connected router 103 as a network channel for data transmission in a certain time period, and the selected router 103 is a target router. In addition, the wireless relay device 101 may perform dynamic switching of network channels among the plurality of connected routers 103 according to a switching scheme configured in advance by the user, so as to ensure that the signal received by the device 102 is strongest.
It should be noted that the positions of the device end 102, the wireless relay device 101, and the router 103 are not specifically limited in the embodiment of the present application, and the position shown in fig. 1 is only an example, and those skilled in the art may make appropriate adjustments according to actual situations. For example: in a house, the routers are arranged in the living room and the toilet, but the bedroom cannot receive signals of the routers arranged in the living room and the toilet, so that a wireless relay device can be arranged in the bedroom, and a person can still have a strong signal when using a device end (such as a computer, a mobile phone and the like) in the bedroom by expanding the signal range of the router in the living room or the toilet to the bedroom.
Based on the data transmission system, the embodiment of the present application provides a data transmission method, in which a wireless relay device performs dynamic switching of network channels according to a real-time situation, and only one connected router is selected as a network channel for data transmission at the same time, so that when a server currently connected has poor signals or the router is damaged, it can still be ensured that a device side maintains good network signals.
The data transmission method provided by the embodiment of the application is described in detail as follows:
referring to fig. 2, fig. 2 is a flowchart of a data transmission method according to an embodiment of the present application, where the data transmission method includes the following steps:
step S201: from the plurality of routers, a target router within a first time period is determined.
Step S202: data is received.
Step S203: and judging whether the data conforms to the data transmission rule.
Step S204: and if the data accords with the data transmission rule, sending the data to the equipment end or the target router.
For example, first, the wireless relay apparatus may determine, among a plurality of routers connected to itself, a target router as a network path in a current time period (i.e., in the first time period in step S201). There are various ways for the wireless relay device to determine the target router, for example: receiving an instruction of a user, and determining a router as a target router according to the instruction; or, determining the target router according to a rule preset by the user, for example: a router with the maximum signal strength is determined as a target router according to the real-time signal strengths of the plurality of routers, and the like, and a part of the determination manner will be illustrated in the following embodiments.
In the embodiment of the present application, for convenience of description, it is assumed that the wireless relay apparatus is respectively connected to three routers: router a, router B, and router C are connected, and it is currently determined that router a is the target router.
After determining the target router, the wireless relay device may receive the data sent by the target router and send the data to the device side, or may receive the data sent by the device side and send the data to the target router. Step S202 to step S204 are described in detail below by taking an example in which the wireless relay device receives data sent by a target router:
and the router A carries out wireless communication with the wireless relay equipment through the WIFI equipment driver and sends the data to the wireless relay equipment. As an embodiment, the data may be received by using a netif _ receive _ skb function, where the netif _ receive _ skb function is an entry for receiving a message in a protocol stack, and is generally called by a driver to send the message into the protocol stack.
After receiving the data sent by the router A, the wireless relay equipment judges whether the data meet the data transmission rule according to skb- > dev when passing through a two-layer bridge processing function br _ handle _ frame _ finish. The data transmission rule may be used to determine whether the data is data sent by the router a (i.e., a target router), or whether the data is wireless authentication data sent by the router B or the router C for maintaining communication connection between the router and the wireless relay device, and the like.
And when the wireless relay equipment judges that the received data accords with the data transmission rule, the data is sent to the equipment end.
Similarly, after receiving the data sent by the router B or the router C, the wireless relay device determines whether the data conforms to the data transmission rule. And when the wireless relay equipment judges that the received data does not accord with the data transmission rule, the data is lost.
It should be noted that the embodiment of the wireless relay device receiving the data transmitted by the device side is similar to the embodiment of the wireless relay device receiving the data transmitted by the target router. As an implementation manner, after the device side sends data to the wireless relay device, the wireless relay device may determine, according to skb- > dev, whether the data is data sent to the router a (i.e., a target router) or whether the data is wireless authentication data sent to the router B or the router C through a two-layer bridge processing function br _ dev _ queue _ push _ xmit.
Determining a plurality of policies for the target router over the first time period from the plurality of routers is described in detail below:
in the first strategy, step S201 may include the following steps:
and determining the router with the highest signal strength in the plurality of routers as a target router.
Specifically, the wireless relay device may select a router with the strongest signal strength as the network channel among the plurality of connected upstream routers, and when the signal of the router connected to the wireless relay device changes, the router with the strongest signal may be preferentially reselected as the network channel under a suitable condition. That is, the channel switching among the routers can be performed to ensure that the router with the best signal strength always performs data transmission with the device side.
For example, assume that the wireless relay device is respectively connected to three routers: router a, router B, and router C are connected, and it is currently determined that router a is the target router. After the whole data transmission system operates for a period of time, the wireless relay device finds that the signal intensity of the router A is low and lower than that of the router B, and immediately switches the router B to be used as a network channel, so that the router with the best signal intensity always performs data transmission with the device end.
In the second strategy, step S201 may include the steps of:
when a router connected to the 5G exists in the plurality of routers, the router connected to the 5G is determined as a target router.
Specifically, if the routers connected to the wireless relay device are all connected to WIFI, the router connected to WIFI 5G may be preferentially selected as the network channel. This is because the channel bandwidth of WIFI 5G is relatively independent, and the interference between channels is small, and adjacent channels of WIFI 2.4G overlap and interfere with each other, so the signal strength of WIFI 5G is relatively higher than that of WIFI 2.4G. That is to say, the channels can be switched among a plurality of routers, so that the routers connected with the 5G are guaranteed to preferentially perform data transmission with the equipment side, and signals are better.
For example, assume that the wireless relay device is respectively connected to three routers: the router A, the router B and the router C are connected, the router A and the wireless relay equipment are connected through WIFI 5G, the router B and the router C are connected through WIFI 2.4G, and the router A is determined to be a target router at present. After the whole data transmission system operates for a period of time, the wireless relay equipment finds that the router A fails, and immediately switches the router B as a network channel; after a period of time, the wireless relay device finds that the router A recovers work, and immediately switches the router A as a network channel.
In a third policy, please refer to fig. 3, where fig. 3 is a flowchart of a method for determining a target router according to an embodiment of the present application, in the method for determining a target router, step S201 may include the following steps:
step S301: and sending a control message protocol to the plurality of routers at regular time.
Step S302: and receiving a plurality of response messages which are returned by the routers and correspond to the control message protocol.
Step S303: and determining the router with the lowest delay for receiving the response message in the plurality of routers as the target router.
Specifically, the wireless relay device may send a Control Message Protocol (ICMP) to the connected routers at regular time, determine packet receiving delays of the connected routers according to the received response messages corresponding to the Control Message Protocol of the router, record the uplink connection with the optimal delay, and switch to the router with the optimal delay as a network channel under appropriate conditions. That is, the switching of the channels among the plurality of routers can be performed to ensure that the router with the minimum network delay always performs data transmission with the device side.
For example, assume that the wireless relay device is respectively connected to three routers: router a, router B, and router C are connected, and it is currently determined that router a is the target router. In the operation process of the whole data transmission system, the wireless relay equipment sends control message protocols to the router A, the router B and the router C every hour, and judges packet receiving delays of the router A, the router B and the router C. After the data transmission system operates for a period of time, the wireless relay equipment finds that the packet receiving delays of the router A and the router C are both larger than the packet receiving delay of the router B, and immediately switches the router B to serve as a network channel, so that the router with the minimum network delay and the equipment end always perform data transmission.
It should be noted that the three policies are merely examples provided in the embodiment of the present application, and in practical cases, the policy for determining the target router in the first time period may also take other manners. In addition, the three policies may be used individually as criteria for determining a target router, or at least two of the first policy, the second policy, or the third policy may also be used to determine the target router.
For example, assuming that a target router is determined in combination with the first policy and the second policy, the wireless relay device is respectively connected to three routers: the router A, the router B and the router C are connected, the router A and the router C are connected with the wireless relay device through WIFI 5G, the router B is connected through WIFI 2.4G, and the router A is determined to be a target router at present. After the whole data transmission system operates for a period of time, the wireless relay equipment finds that the signal intensity of the router A becomes low and is lower than the signals of the router B and the router C, and immediately switches the router C which is also connected by the WIFI 5G to serve as a network channel, so that the strongest signal received by the equipment end is ensured on the basis of preferentially adopting the WIFI 5G connection.
The following describes in detail various situations for determining whether data conforms to the data transmission rule:
in the first case, step S203 may include the steps of:
judging whether the data is the data sent by the target router; or, whether the data is data addressed to the target router is judged.
Specifically, in order to ensure that only one network channel is connected in the data transmission process, it may be determined whether the data sent or received by the wireless relay device is received or sent by the target router. Therefore, whether the data is the data in the data transmission process between the target router and the equipment end can be judged, and the data transmission between only one router in the plurality of routers and the equipment end is ensured, so that errors in the data transmission process are reduced.
In the second case, step S203 may include the steps of:
it is determined whether the data is wireless authentication data from a plurality of routers.
Specifically, although only one network channel is connected in the data transmission process, the routers connected to other nodes still need to maintain the WIFI connection. As an embodiment, the wireless authentication data, such as ethernet _ TYPE _802_1X or ethernet _ TYPE _802_1X _ PREAUTH, may be unconditionally passed through, so that the wireless relay device maintains connection with another router, and a switching channel may be quickly selected between the connected routers.
In the embodiment of the application, the wireless relay device can establish wireless connection with a plurality of routers, and determine one router from the plurality of connected routers as a network channel, and the device end can only perform data transmission with the router, so that when the server connected at present is poor in signal or the router is damaged, the device end can still be ensured to maintain a better network signal.
Referring to fig. 4, fig. 4 is a block diagram of a data transmission apparatus according to an embodiment of the present application, where the data transmission apparatus 400 is applied to a wireless relay device, and includes: a determining module 401, configured to determine, from a plurality of routers, a target router within a first time period; a receiving module 402, configured to receive data; the data is sent by the target router or sent by the equipment end; a judging module 403, configured to judge whether the data conforms to a data transmission rule; a sending module 404, configured to send the data to a device side or to the target router if the data conforms to the data transmission rule.
In this embodiment of the present application, the wireless relay device may establish wireless connection with multiple routers, and determine, by using the determining module 401, one router from the multiple connected routers as a network channel, and the device end may only perform data transmission with the router, so that when a server currently connected is poor in signal or the router is damaged, it is still ensured that the device end maintains a better network signal.
Further, the determining module 403 is further configured to: judging whether the data is the data sent by the target router; or judging whether the data is the data sent to the target router.
In this embodiment of the present application, the determining module 403 may ensure that only one router in the plurality of routers performs data transmission with the device side by determining whether the data is data in the data transmission process between the target router and the device side, so as to reduce errors occurring in the data transmission process.
Further, the determining module 403 is further configured to: judging whether the data are wireless authentication data from the routers or not; wherein the wireless authentication data is used to maintain one of the plurality of routers in communication connection with the wireless relay device.
