Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for managing a communication channel, an electronic device, and a readable medium.
Background
At present, there are many implementation protocols for Wireless local area networks, and the most famous and most widely used belong to the Wireless-Fidelity (WI-FI) protocol. 802.11ax is a recently introduced wlan standard that supports both 2.4G and 5G bands, and achieves greater radio capacity and reliability by applying denser modulation, reducing subcarrier spacing (78.125kHZ), and scheduling-based resource allocation, as compared to previous generation technologies.
According to a Transmission Control Protocol (TCP), when data of an application layer is communicated, frequent Acknowledgement is performed on a transport layer to ensure reliable Transmission of the data, however, an Acknowledgement (ACK) message for Acknowledgement is short, efficiency of transmitting the ACK message is low, and more collisions and congestion are caused to a wireless local area network (wlan), that is, a mechanism of TCP Transmission itself limits throughput of the data in the wlan to a certain extent.
In the related art, a rate adaptive algorithm may be employed to dynamically adjust the transmission rate. The physical layer of the IEEE802.11 wireless network supports many different modulation and coding schemes, and selects a suitable transmission rate according to different wireless channel conditions, so as to effectively improve the throughput of network nodes, and the mainstream rate adaptive algorithm includes the following steps:
(1) rate adaptation algorithm for ack (acknowledgement) based feedback acknowledgement frame error rate.
(2) A rate adaptation algorithm based on the channel signal to noise ratio (SNR).
(3) The algorithm of measuring the whole wireless channel condition according to the SNR fed back to the transmitting end by the receiving end can quickly react to the channel change.
Existing channel switching schemes not only require additional overhead to convey information, but also limit throughput improvements. In addition, when the data frame is lost due to collision, the rate adaptive algorithm is also adversely affected, and the channel switching scheme is unreliable.
It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.

Referring to fig. 2, the management method of a communication channel may include:
step S202, detecting the collision rate of two communication channels of a terminal, wherein the frequency points of the two communication channels are different.
Step S204, determining the communication channel with high collision rate in the two communication channels to be used for transmitting the first type of messages.

In an exemplary embodiment of the present disclosure, the first type of packet is a data packet, and the second type of packet is an ACK packet.
Specifically, the MAC layer protocol used in the wireless local area network is CSMA/CA (carrier sense multiple access/collision avoidance). In the protocol, a node monitors a channel before sending a data frame, if the channel is idle, the node can send the data frame after waiting for a period of DIFS (Distributed Inter-frame Spacing), and if the channel is busy, the node needs to randomly back off for a period of time to detect again, which is to actively avoid collision. The protocol adopts a stop-wait mechanism, and the source node needs to wait for the ACK response of the receiving node after sending the data frame, so that the data frame is transmitted. In order To reduce the probability of collision and the influence of collision as much as possible, the 802.11 standard allows a station that is To transmit data To reserve a channel, transmits an RTS (request To Send) frame including a source address, a destination address, and a time required for this communication before transmitting a data frame, and realizes reservation of the channel after receiving a CTS (Clear To Send) frame of a destination station.

step S402, determining whether the collision rate for transmitting the first type of packet is less than or equal to a preset collision rate, and determining whether the collision rate for transmitting the second type of packet is less than or equal to the preset collision rate, if so, performing step S404, and if not, performing step S406.
Step S404, if the collision rate for transmitting the first type of message is judged to be less than or equal to the preset collision rate, and the collision rate for transmitting the second type of message is judged to be less than or equal to the preset collision rate, determining not to switch the communication channel.

step S402, judging whether the collision rate for transmitting the first type of messages is less than or equal to a preset collision rate, and judging whether the collision rate for transmitting the second type of messages is less than or equal to the preset collision rate.
Step S406, if it is determined that the collision rate for transmitting the first type of message is greater than the preset collision rate, or it is determined that the collision rate for transmitting the second type of message is greater than the preset collision rate, determining whether the communication channel is switched according to a collision rate difference between the collision rate for transmitting the first type of message and the collision rate for transmitting the second type of message.
In an exemplary embodiment of the present disclosure, the preset collision rate may be 40%.
In an exemplary embodiment of the present disclosure, as shown in fig. 5, if it is determined that the collision rate for transmitting the first type of packet is greater than the preset collision rate, or that the collision rate for transmitting the second type of packet is greater than the preset collision rate, determining whether to switch the communication channel according to a collision rate difference between the collision rate for transmitting the first type of packet and the collision rate for transmitting the second type of packet includes:
step S502, if the collision rate for transmitting the first type of messages is judged to be larger than the preset collision rate, or the collision rate for transmitting the second type of messages is judged to be larger than the preset collision rate, calculating a collision rate difference value between the collision rate for transmitting the first type of messages and the collision rate for transmitting the second type of messages.
And step S504, comparing the size relationship between the collision rate difference value and a preset collision rate difference value.

In an exemplary embodiment of the present disclosure, the preset collision rate difference may be 20%.
In an exemplary embodiment of the disclosure, as shown in fig. 6, determining whether the communication channel is switched according to a magnitude relationship between the collision rate difference value and the preset collision rate difference value includes:
step S602, if it is determined that the collision rate difference is greater than the preset collision rate difference, it is determined that the communication channel is switched.

step S604, if it is determined that the collision rate difference is smaller than or equal to the preset collision rate difference, determining that the communication channel is not switched.
In an exemplary embodiment of the present disclosure, as shown in fig. 7, there is one access point AP 702, one terminal 708 equipped with a dual network card, and one channel control center 710 in the wireless local area network.
The AP 702 may support simultaneous communication with the terminals 708 at two frequency points f1 and f2, each terminal 708 is equipped with two wireless network cards, namely a network card 1704 and a network card 2706, and the two frequency points are connected to the two network cards of the terminals 708, respectively, to form two transmission channels, which are respectively denoted as a channel with frequency f1 and a channel with frequency f 2. All TCP sessions between a terminal 708 and the AP 702 use both channels simultaneously, where TCP data messages and ACK messages are transmitted using different channels.
The datagram generated by the upper layer application of the terminal 708 is sent out through the network card 1704 or the network card 2706, the AP 702 sends the data packet through the channel with the frequency f1 or the channel with the frequency f2, and the terminal 708 sends the data packet received from the two network cards to the upper layer application through the virtual switch (v-switch) software.
The channel control center 710 performs a channel switching decision on the TCP data message and the ACK message transmitted between the AP 702 and the terminal 708 according to the channel congestion information reported by the AP 702, and instructs, if necessary, to switch the TCP data message and the ACK message to the original channels of the TCP data message and the ACK message, respectively, for transmission.
The above-mentioned system for implementing the management scheme of the communication channel of the present disclosure has the following working flows:
(1) the AP 702 is connected to the network card 1704 and the network card 2706 of the terminal 708 by using two frequency points f1 and f2, continuously counts the collision rate of the two channels, and reports the collision rate to the channel control center 710 at intervals.
(2) The channel control center 710 transmits control information to the AP 702 and the terminal 708 according to the information reported by the AP 702, so that the TCP data packet is transmitted on the channel with a small collision rate, and the TCP ACK packet is transmitted on the channel with a large collision rate.
For example, if the designated time f1 is less than the f2, the AP 702 receives the control information, recognizes the TCP datagram from the external network, changes the destination IP address to the IP of the network card 1704, and transmits the TCP datagram through the f1 channel, and recognizes the ACK packet from the external network, changes the destination IP address to the IP of the network card 2706, and transmits the ACK packet through the f2 channel.
Similarly, the terminal 708 is also the same, and the data packets of the network card 1704 and the network card 2706 are processed by the v-switch and then forwarded to the terminal 708, when data is sent, the v-switch recognizes a TCP data message and forwards the TCP data message to the network card 1704, and recognizes an ACK message of the TCP and forwards the TCP data message to the network card 2706. The AP 702 counts the collision rate on two channels every T seconds and sends the collision information to the channel control center 710.
Further, the channel control center 710 determines whether to switch channels according to the following rule according to the collision information of the last T seconds: when the collision rate of any one channel exceeds a certain set threshold α and the absolute value of the difference between the collision rates of the two channels is greater than a certain set threshold β, channel switching is performed, and at this time, the channel control center 710 sends a channel switching signaling to control the AP 702 and the terminal 708 to perform channel switching.
As shown in fig. 8, the terminal 802 performs data communication with the AP 804 in the wireless network, and performs TCP data packet transmission through the channel with the frequency f1 and ACK packet transmission through the channel with the frequency f2, and after performing channel switching according to the embodiment of the present disclosure, performs TCP data packet transmission through the channel with the frequency f2 and ACK packet transmission through the channel with the frequency f 1.
Specifically, the AP 804 connects with two network cards of the terminal 802 through two frequency points, and in the authentication process of establishing connection, the AP 804 recognizes that the IP addresses of the two network cards belong to one device, and establishes a mapping relationship between the terminal 802 and the two IP addresses thereof in the operating data of the AP 804. The TCP datagram is transmitted to the network card 1 through the channel with the frequency f1, the ACK packet of the TCP is transmitted to the network card 2 through the channel with the frequency f2, when the AP 804 receives the TCP datagram of the external network, the destination IP address is changed to the network card 1, and when the ACK of the external network is received, the destination IP address is changed to the network card 2. The AP 804 continuously monitors the collision rate of the data packets on the two frequency channels, and transmits channel congestion information to the channel switching control management center every 2 s.
The terminal 802 with the double network cards realizes the received TCP data integration of the two network cards by deploying v-switch software, a channel with frequency f1 is connected with the network card 1 to transmit TCP datagrams, a channel with frequency f2 is connected with the network card 2 to transmit ACK packets of TCP, the v-switch adopts a full disk acceptance strategy for the data packets transmitted by the two network cards, the TCP data packets transmitted from the terminal 802 are forwarded to the network card 1 according to the types of the data packets, the ACK packets of TCP are forwarded to the network card 2, and the network card 1 and the network card 2 transmit the respective datagrams on respective wireless channels.
The channel control center decides the channel switching according to the channel congestion condition of the first 2s reported by the AP 804, and the channel switching is possible only when the collision rate of any one channel is higher than 40%, and this parameter is recommended to be set between 35% and 55%, and this parameter is an absolute limit for channel switching.
If the channel collision rate is low, channel switching is not necessary, and if the value is set too high, the sensitivity of channel switching is reduced, and the user experiences obvious network congestion. When the collision rate of any channel is higher than 40%, the channel switching is relatively limited, when the collision rate of the TCP datagram transmission channel is higher than 20% of the other channel, the channel switching is executed, the parameter is recommended to be set between 10% and 20%, if the value is set to be too small, the channel switching is too frequent, and according to the practical view, if the collision rates of the two channels are close, the channel switching is not necessary. If the value is set too large, channel switching will be sluggish and the user will experience a noticeable network upset.
The embodiment of the disclosure not only changes the transmission mode of data and data ACK of one terminal 802 in the same channel, that is, one terminal 802 is used to configure a dual network card to establish channels with different APs 804, but also allows the data and the data ACK to be transmitted in different channels, thereby greatly improving the TCP throughput in the WLAN.
Corresponding to the above method embodiment, the present disclosure further provides a management apparatus for a communication channel, which may be used to execute the above method embodiment.
