Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a system architecture diagram of a Wireless Local Area network system according to an embodiment of the present invention, and as shown in fig. 1, the Wireless Local Area Network (WLAN) system according to the embodiment includes a Wireless Access Point (Access Point, AP for short) and a workstation (STA for short), and the STA accesses an ethernet through the Wireless AP. The WIFI-based wireless local area network system is realized based on IEEE 802.11 series standards, and is a wireless local area network using high-frequency wireless radio frequency (such as wireless electromagnetic waves with frequency bands of 2.4GHz, 5GHz, 60GHz and the like) as a transmission medium.
The wireless AP is a wireless switch for a wireless network and is also a core of the wireless network. Wireless APs are access points for mobile computer users to access wired networks, primarily for use in broadband homes, inside buildings, and inside parks, typically covering distances from tens of meters to hundreds of meters. Wireless access points AP can be integrated in a wireless router, a part of Digital Subscriber Line (DSL CPE), a terminal Device (Cable Modem, CM for short), and an Optical Network Unit (ONU for short).
The STA in the WLAN is generally a client, and may be a computer equipped with a wireless network card, or a smart phone, a smart television, a PAD, a movie box, etc. with a WiFi module. The STAs may be mobile or stationary.
When the wireless AP communicates with the STA, the wireless AP may acquire a downlink packet from the ethernet and then transmit the downlink packet to the STA, or the STA may transmit an uplink packet to the wireless AP and then transmit the uplink packet to the ethernet. The message related in this embodiment is mainly a downlink message received by the wireless AP from the ethernet.
Fig. 1 shows only one system architecture of the wireless lan system, and for other system architectures, as far as the connection between the wireless AP and the STA is concerned, the protection scope of the present invention is included. For other system architectures, the present embodiment is not described herein again.
Based on the problem that a fault point of a WiFi network cannot be located in a wireless local area network system, an embodiment of the present invention provides a method for obtaining a message processing delay, by which a processing delay of a wireless AP in processing a data message can be obtained, and according to the processing delay, it can be determined whether a fault of the WiFi network is generated by the AP in the system architecture. The following examples are given for illustrative purposes.
Fig. 2 is a flowchart of a method for obtaining a message processing delay according to an embodiment of the present invention. Fig. 3 is a schematic view of a processing scenario of a data packet provided in the present invention. As shown in fig. 3, the execution subject of the present embodiment is a processor in a wireless AP, and as shown in fig. 2, the method includes:
Referring to fig. 3, a data packet of the WAN enters the wireless AP from a WAN (wide area network, WAN for short) interface of the wireless AP, and the data packet of the WAN may be, for example, a data packet of an ethernet. The WAN Interface is used to access the wireless AP to a wide area network, and may use ethernet access, Digital Subscriber Line (DSL) access, coaxial access (e.g., Data Over Cable Service Interface Specifications (DOCSIS), multimedia Over Cable Service Interface alliance MoCA), fiber access, power Line communication access, and the like.
After receiving the data packet, the WAN interface transmits the data packet to an ethernet switch (LSW), that is, the LSW receives the data packet from the wide area network through the WAN interface. After receiving the data message, the LSW performs an exchange process on the data message. After the exchange processing is completed, the LSW stores the data message into the storage space corresponding to the LSW, and then the LSW sends a message notification message to the processor.
The processor receives a message notification message sent by the LSW, and acquires the time for receiving the message notification message as a first time. The message notification message is used to indicate that the processing of the data message is to be started, and represents that the processor needs to start a processing flow for the data message.
After receiving the message notification message, the processor acquires the data message from the storage space of the LSW according to the indication of the message notification message, and then processes the data message to obtain a processed data message. The processing of the data message mainly includes at least one of the following processing. The following are detailed below.
And storing the data message. The processor obtains the data message from the storage space of the LSW and stores the data message in the memory of the wireless AP.
And converting the data message. The processor converts the data packet stored in the memory, for example, converts the data packet of the ethernet into a WIFI packet, i.e., a packet specified by the 802.11 protocol, or may also perform conversion processing such as aggregation and fragmentation on the data packet.
And scheduling the data message. Since there may be multiple data packets to be sent in the memory, the processor needs to schedule the data packets stored in the memory to determine the sending order of the data packets.
And competing the air interface sending opportunity of the data message. The processor contends for the air interface transmission opportunity according to a contention mechanism of WiFi, such as a contention mechanism of carrier sense multiple access/collision avoidance protocol (CSMA/CA). I.e. the channel required for contention data message transmission.
Those skilled in the art can understand that the above processing on the data packet may be performed by all the above processing procedures, or may perform several processing procedures. The embodiment is not particularly limited herein with respect to the specific implementation. When the above processes are all executed, the processes can be executed according to the processes of storage, conversion, scheduling and competition.
And after the processor finishes processing the data message, the processor sends the data message to the STA through the WIFI chip. The WIFI chip can bear a WIFI interface, and the data message can be sent to the STA through the WIFI interface.
After receiving the data packet, the STA replies an acknowledgement packet to the wireless AP for the data packet to indicate that the data packet is successfully received. However, when some transmission errors may result in a loss of the acknowledgment packet or the acknowledgment packet indicates that the data packet received by the STA is erroneous, the wireless AP determines that the data packet transmission fails, the wireless AP starts a retransmission mechanism of the data packet, at this time, the wireless AP performs processing procedures such as scheduling and contention on the data packet again, and then retransmits the data packet, and if the data packet retransmission fails, the wireless AP determines that the data packet transmission fails, discards the data packet, and records the discarded data packet, thereby obtaining a packet loss rate.
Further, when the packet loss rate is calculated, statistics of packet loss statistics is performed according to the lost packet. For example, the total number of messages, the total traffic, the number of packet losses, the packet loss rate, and the like, where the packet loss rate may be the packet loss rate in each time interval.
Those skilled in the art can understand that the acknowledgment packet obtained in this embodiment may be an acknowledgment packet corresponding to a first-time transmission data packet, and may also be an acknowledgment packet corresponding to a retransmission process.
After the WIFI chip of the wireless AP receives the confirmation message, recording the time for receiving the confirmation message, and sending the time for receiving the confirmation message to the processor, wherein the processor takes the time as second time after acquiring the time for receiving the confirmation message.
After obtaining the first receiving time T1 and the second receiving time T2, the processor may calculate the processing delay of the data packet. Since the first receiving time is the time of receiving the message notification message, i.e. the time of preparing to start processing the data message. Therefore, the processing delay calculated by the first receiving time and the second receiving time mainly includes the processing delay of the processor in the processing process and the round trip delay, i.e. the delay of the processor in the processes of storing, converting, scheduling, competing and the like.
In calculating the processing delay, the processing delay may be obtained by way of T2-T1, or by way of various variations of T2-T1, such as in the form of aT2-bT1, or
Wherein a and b are delay coefficients.
It is understood by those skilled in the art that the present embodiment only takes one data packet as an example to illustrate the delay of the data packet. In a specific implementation process, the wireless AP may send a plurality of data packets to the STA, and at this time, the wireless AP may perform statistics on processing delays of a preset number of data packets. Thereby, the average delay, the maximum delay, the minimum delay, the statistical parameters of the delay in each time interval, etc. can be obtained.
The method for obtaining a message processing delay according to this embodiment obtains a message notification message by receiving the message notification message and obtaining a time for receiving the message notification message as a first receiving time, where the first receiving time is a starting time for processing a data message, obtains the data message according to an instruction of the message notification message after obtaining the first receiving time, processes the data message to obtain a processed data message, sends the data message to an STA, and obtains a time for receiving an acknowledgement message returned by the STA as a second receiving time, where the second receiving time is a time for successfully sending the acknowledgement message, and may calculate a processing delay of the data message according to the first receiving time and the second receiving time, and may monitor a service quality of a wireless AP according to the processing delay, where a value of the processing delay exceeds a preset value when a network performance does not meet a standard, the wireless AP is indicated to be in fault, so that the device in fault can be positioned as the wireless AP.
The following describes a specific implementation process of the processor converting the data message and acquiring the second receiving time in the above embodiments by using a detailed embodiment.
In a specific implementation process, the data messages entering from the WAN interface of the wireless AP and the data messages sent from the WIFI chip have multiple corresponding relationships, which may be one-to-one relationships, the data messages received by the WAN interface may also be fragmented into multiple messages to be sent from the WIFI chip, and the multiple data messages received by the WAN interface may also be aggregated into one message to be sent from the WIFI chip.
In a specific example, for example, when the wireless local area network is implemented based on the 802.11 protocol, the data packet needs to be converted into a packet specified by the 802.11 protocol when being sent to the STA through the WIFI chip. At this time, the correspondence relationship between the two may be a one-to-one correspondence relationship, or the message received by the WAN interface may be fragmented into a plurality of messages specified by the 802.11 protocol, or the plurality of messages received by the WAN interface may be aggregated into one message specified by the 802.11 protocol.
If the two are different in correspondence, the corresponding processes for acquiring the transmission information of the packet are different, and detailed descriptions will be given below.
According to a feasible implementation mode, the corresponding relationship between the data message received from the WAN interface and the data message sent from the WIFI chip is one-to-one. For a specific implementation process of this implementation, reference may be made to the embodiment shown in fig. 2, and details of this embodiment are not described here.
Fig. 4 is a schematic flow chart of data packet transmission according to an embodiment of the present invention. As shown in fig. 4, the method includes:
In this embodiment, after the processor acquires the data packet from the storage space of the LSW, if the size of the data packet is larger than a Maximum Transmission Unit (MTU) corresponding to the WIFI interface, the processor performs fragmentation processing on the data packet to obtain a plurality of first data packets. And then the processor sequentially sends a plurality of first data messages to the STA through the WIFI interface and receives first confirmation messages returned by the STA aiming at the first data messages.
Specifically, fig. 5 is a schematic diagram of a first data packet transmission process according to an embodiment of the present invention, please refer to fig. 5, where a processor performs fragmentation processing on the data packet to obtain three first data packets. The processor sequentially sends first data messages to the STA through the WIFI interface.
For example, the wireless AP sends a first data message 10 to the STA, and after the STA receives the first data message successfully, the STA returns a first acknowledgement message ACK to the wireless AP; the wireless AP sends a first data message 20 to the STA, and after the STA receives the data successfully, the STA returns a first acknowledgement message ACK to the wireless AP; the wireless AP sends a first data packet 30 to the STA, and after the STA receives the first data packet successfully, the STA returns a first acknowledgement packet ACK to the wireless AP. At this point, the wireless AP sends the data packet to the STA successfully.
In the process, for any first data packet, if the first data packet fails to be sent for the first time, a retransmission mechanism is started, the first data packet is retransmitted to the STA, and when the retransmission is successful, a first acknowledgement packet of the first data packet corresponding to the retransmission process is obtained; and when the retransmission fails, the first data message fails to be sent.
After the transmission process of the data message is finished (the transmission process of the data message includes a retransmission process), acquiring the time of each first confirmation message returned by the receiving STA, and judging whether the STA returns the first confirmation message for all the first data messages, if so, taking the time of receiving the last first confirmation message as the second receiving time. It will be appreciated by those skilled in the art that the last acknowledgment message may be an acknowledgment message of a retransmission process.
In the embodiment shown in fig. 5, if the first acknowledgement packet ACK corresponding to the first data packet 30 is the last first acknowledgement packet, the time for receiving the first acknowledgement packet corresponding to the first data packet 30 is taken as the second receiving time. And if the STA does not return the first confirmation message aiming at all the first data messages, the data message is considered to be failed to be sent.
In this embodiment, the data packets are fragmented to obtain a plurality of first data packets, then the first data packets are sequentially sent to the STA, and then the second receiving time is determined according to the receiving time of each first acknowledgment packet, so that the second receiving time can be obtained for the fragmented packets, and thus, when the wireless AP performs the packet fragmentation processing operation, the service quality of the wireless AP can be monitored.
Fig. 6 is a schematic flow chart of data packet transmission according to an embodiment of the present invention. As shown in fig. 6, the method includes:
601, carrying out aggregation processing on the data message and other data messages to obtain a second data message;
In this embodiment, after the processor obtains the data packet from the storage space of the LSW, if the size of the data packet is smaller than a Maximum Transmission Unit (MTU) corresponding to the WIFI interface, the processor aggregates the data packet with other data packets to obtain a second data packet. And then the processor sends a second data message to the STA through the WIFI interface.
Specifically, fig. 7 is a schematic diagram of a data packet transmission process according to an embodiment of the present invention, please refer to fig. 7, where the processor performs aggregation processing on the data packet 10, the data packet 20, and the data packet 30, that is, performs aggregation processing on data portions of three data packets, and then adds a packet header (not shown) to form a second data packet. For convenience of illustration in this embodiment, fig. 7 schematically shows that data packet 10, data packet 20, and data packet 30 are aggregated into a second data packet.
After the second data message is obtained through aggregation, the wireless AP sends the second data message to the STA, and after the STA receives the second data message, the STA returns a block acknowledgement message BA to the wireless AP. In the block acknowledgement message, receiving information for indicating whether the data message was received successfully is included. For example, if data packet 10 and data packet 30 are successfully received, then in the block acknowledgement message, receipt information indicating that data packet 10 and data packet 30 were successfully received is included. Optionally, a receipt message indicating that the data packet 20 failed to be accepted may also be included.
For the data packet 20, the retransmission processing is performed on the data packet 20, and during the retransmission processing, the aggregation processing is also performed on the data packet 20. Those skilled in the art will appreciate that retransmission corresponds to both retransmission failure and retransmission success. If the retransmission is successful, the block acknowledgement message corresponding to the retransmission process includes reception information indicating that the data packet 20 is successfully received.
Therefore, after receiving the second acknowledgement packet through the WFII interface, the processor determines whether the second acknowledgement packet includes the reception information indicating that the data packet is successfully received, and if the second acknowledgement packet includes the reception information indicating that the data packet is successfully received, the processor determines that the second acknowledgement packet (block acknowledgement packet BA) is received as the second reception time of the data packet 10 and the data packet 30. For the data packet 20, if the retransmission of the data packet 20 fails, the second acknowledgement message includes reception information indicating that the data packet 20 was received unsuccessfully, thereby determining that the data packet 20 failed to be transmitted.
In this embodiment, the data packet is aggregated to obtain a second data packet, the second data packet is sent to the STA, and a second receiving time is obtained according to the receiving time of the second acknowledgment packet, so that the second receiving time can be obtained for the aggregated packet, and thus, when the wireless AP performs the packet aggregation operation, the service quality of the wireless AP can be monitored.
Those skilled in the art will appreciate that in the above embodiments shown in fig. 4 to fig. 7, the receiving time of each acknowledgment packet is similar to that in the embodiment shown in fig. 2, that is, the WIFI chip records the receiving time of each acknowledgment packet, and then the WIFI chip sends each receiving time to the processor, and the processor determines the second receiving time according to each receiving time.
