Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The user equipment can be connected with the BRAS equipment, the BRAS equipment sends the request information of the user to the AAA server, and the AAA server can finish the authentication, authorization and accounting of the user, and then the user can enjoy the network service. Since BRAS equipment carries a large number of users, a large number of authentication request messages or accounting update request messages need to be processed by the AAA server in a certain period. However, the AAA server has limited processing capability and cannot concurrently process too many authentication request messages or charging update request messages. The number of the authentication request messages or the charging updating request messages which are sent to the AAA server by the BRAS device but have not received the response is counted by the message counter, and the message counters for counting the number of the authentication request messages and the charging updating request messages are different. The BRAS equipment adds 1 to the corresponding message counter after sending an authentication request message or an accounting update request message to the AAA server, and subtracts 1 from the message counter after receiving a response message or the authentication request message or the accounting update request message is overtime. When the value of the message counter reaches the maximum value, the BRAS equipment stops sending an authentication request message or an accounting update request message to the corresponding AAA server, and caches the authentication request message or the accounting update request message to be sent subsequently. And when the value of the message counter is lower than the maximum value, the BRAS equipment sequentially sends the cached authentication request messages or the cached charging updating request messages according to the caching sequence. The number of authentication request messages or charging update request messages that can be currently sent depends on the difference between the counter value and the maximum value.
However, after the message counter reaches the estimated maximum value, the buffer queue of the BRAS equipment is limited, and if the buffer queue is enlarged, a lot of storage space is consumed. And if more cache messages in the BRAS equipment are not sent to the AAA server, the cache messages cannot be responded by the AAA server, the user has limited tolerable waiting time, and the retransmission is delayed, which aggravates the message pressure. In addition, if the buffer messages are sequentially sent after the sending queue is slightly relieved, the user equipment may retransmit a new request in an overdue manner, so that it is meaningless to send the buffer messages. Therefore, the method for responding the message easily causes the congestion of the authentication request message or the charging updating request message, so that the authentication request message or the charging updating request message cannot be responded, and the user experience is influenced.
Referring to fig. 2, fig. 2 is a flow chart of message processing among the user equipment, the BRAS equipment, and the AAA server, and it can be seen that the message processing includes: the method comprises the steps of message processing between user equipment and BRAS equipment and message processing between the BRAS equipment and an AAA server. The message processing flow in fig. 2 includes the following stages:
PPPOE (Point to Point Protocol over Ethernet, Point to Point communication Protocol based on Ethernet) negotiation stage: if the user equipment starts PPPOE session, the user equipment must first perform discovery phase, the purpose of the discovery phase is to obtain the MAC (Media Access Control) address of the BRAS device and establish a unique PPPOE session ID. After the discovery phase is finished, a standard PPP session phase, namely a PPP negotiation phase, is entered.
PPP (Point to Point Protocol) negotiation stage: the establishment of a PPP session requires that both end devices (user equipment and BRAS devices) send LCP packets to configure and test the data communication link. And the user equipment and the BRAS equipment carry out the PPP session according to the PPP session connection parameters negotiated in the discovery phase. Once the PPPOE session starts, the PPP data can be sent in any other PPP encapsulation, the session ID of the PPPOE session being the value assigned during the discovery phase. The PPP negotiation phase includes: LCP negotiation phase, authentication phase, and NCP negotiation phase. The authentication phase may be PAP authentication or CHAP authentication.
Taking CHAP authentication as an example for explanation, the CHAP authentication process specifically includes: and the BRAS equipment sends the randomly generated Challenge message to the user equipment to be authenticated. After receiving the Challenge message, the user equipment searches whether a user with the same host name exists in the user table or not according to the host name in the Challenge message and the user table of the user equipment, if the user with the same host name as the BRAS equipment in the user table is found, the Password of the user and the Challenge message generate a Challenge-Password through an MD5 algorithm, and the Challenge-Password and the user name of the user equipment are sent to the BRAS equipment in a Response message. And the BRAS equipment sends the Challenge, the Challenge-Password and the user name of the user equipment to an AAA server together, and the AAA server performs authentication. AAA server judges whether the user is legal according to the user information, and responds authentication success/failure message to BRAS equipment. If the authentication is successful, the authentication request response message returned by the AAA server carries the negotiation parameters and the related service attributes of the user to authorize the user, and the BRAS equipment returns the authentication result to the user equipment, and then the user can be on-line. If authentication fails, the process ends.
As can be seen from the above, at a certain time or within a certain time period, the BRAS device sends a large amount of authentication request messages to the AAA server, so that the AAA server cannot respond to a large amount of authentication request messages in time, and the online of a network user is affected. Similarly, when charging the user, the BRAS device sends a large amount of accounting update request messages to the AAA server, so that the AAA server cannot respond to the accounting update request messages in time. In order to solve the problem, embodiments of the present disclosure provide a message processing method and apparatus, a related electronic device, and a readable storage medium, so that a large number of authentication request messages or charging update request messages are smoothly processed, and influence on user experience due to congestion of the authentication request messages or the charging update request messages is avoided.
First, a detailed description is given below of a message processing method provided in the embodiment of the present disclosure.
Referring to fig. 3, fig. 3 is a flowchart of a message processing method according to an embodiment of the present disclosure, where an execution subject of each step in the embodiment of fig. 3 may be a BRAS device, and the method includes the following steps:
s301, receiving a discovery message sent by user equipment.
Specifically, in the PPPOE negotiation stage in fig. 2, the ue broadcasts and sends a discovery packet, that is, a PADI packet, where the PADI packet is used for the ue to discover BRAS devices in a Virtual Local Area Network (VLAN). The PADI message at least comprises a label of a service name type, and the service to be provided is provided for the BRAS equipment.
S302, if it is determined that the load of the AAA server exceeds the first preset threshold, returning a response packet for a negative response to the discovery packet, where the response packet includes a first delay time, so that the user equipment retransmits the discovery packet after the first delay time.
In the embodiment of the present disclosure, in the authentication phase of PPP negotiation, the BRAS device needs to send an authentication Request message, i.e., an Access Request in fig. 2, to the AAA server, so that the AAA server authenticates the user. When the load of the AAA server exceeds a first preset threshold value, the AAA server is indicated to be incapable of processing the authentication request message sent by the BRAS equipment, wherein the load of the AAA server is the number of the authentication request messages or the accounting update request messages which are sent to the AAA server but do not receive the response of the AAA server, the first preset threshold value is a value determined according to the processing capacity of the AAA server, and the processing capacity of the AAA server comprises the following steps: the Processing performance of a CPU (Central Processing Unit). Therefore, in order to relieve the processing pressure of the AAA server and delay the time for the BRAS device to send the authentication request message, in the PPPOE negotiation stage, the BRAS device sends a PADO response message to the user equipment, where the PADO response message is a message for negative response to the discovery message, so that the user equipment may not continue to send subsequent PADR request messages. When the BRAS device responds to the PADI packet, the returned PADO response packet carries a first delay time, where the first delay time is used to enable the user equipment to resend the discovery packet after the first delay time, and the first delay time is a delay time corresponding to a first preset threshold.
After receiving the PADO response message, the user equipment analyzes the first delay time in the PADO response message, after waiting for the first delay time, the user equipment resends the PADI message to the BRAS equipment, and the BRAS equipment returns a response message aiming at the resent discovery message. In this way, the BRAS device responds negatively to the PADI packet, and causes the user equipment to resend the PADI packet and respond to the resent discovery packet, thereby performing delay processing on the PADI packet. As can be known from the message processing flow in fig. 2, after the PADI message is delayed, correspondingly, the user equipment also delays when sending the PADR message in the PPPOE negotiation stage, and further, each step after the PPPOE negotiation stage is delayed, that is, the time for the BRAS device to send the authentication request message to the AAA server is delayed, so that the processing pressure of the AAA server on the authentication request message is reduced. It can be seen that the purpose of the disclosed embodiments is to relieve the processing pressure of the AAA server, and the specific procedure for relieving the processing pressure of the AAA server is between the user equipment and the BRAS equipment.
In the message processing method provided by the embodiment of the disclosure, after the BRAS device receives the discovery message sent by the user equipment, if it is determined that the load of the AAA server exceeds the first preset threshold, a response message for a negative response to the discovery message is returned, where the response message includes a first delay time so that the user equipment resends the discovery message after the first delay time. According to the embodiment of the disclosure, when the load of the AAA server exceeds the first preset threshold, the discovery message sent by the user equipment is negatively responded, and the user equipment responds after resending the discovery message, so that the discovery message is delayed, the time for the BRAS equipment to send the authentication request message to the AAA server is further delayed, the processing pressure of the AAA server on the authentication request message when a large number of users are simultaneously on line is reduced, the congestion of the authentication request message in the AAA server is avoided, the authentication request message is smoothly processed, and the user experience is improved.
Corresponding to the embodiment of fig. 3, an embodiment of the present disclosure further provides a message processing method, which is applied to a user equipment, referring to fig. 4, where fig. 4 is another flowchart of the message processing method according to the embodiment of the present disclosure, and an execution main body of each step in the embodiment of fig. 4 may be the user equipment, and includes the following steps:
s401, sending the discovery message to BRAS equipment.
S402, after receiving a response message of a negative response returned by the BRAS equipment for the discovery message, analyzing a first delay time in the response message of the negative response; and after the first delay time, the discovery message is retransmitted to the BRAS equipment.
Specifically, in the embodiment of fig. 3, since the response message of the BRAS device to the negative acknowledgement sent by the discovery message includes the first delay time, the first delay time is used for the user equipment to resend the discovery message after the first delay time. In order to cooperate with the BRAS device, the user equipment in the embodiment of the present disclosure may resolve the first delay time in the response message of the negative acknowledgement, accordingly. And after the first delay time, the discovery message is retransmitted to the BRAS equipment.
And S403, receiving a response message returned by the BRAS equipment aiming at the retransmitted discovery message.
In the embodiment of the disclosure, after the user equipment retransmits the discovery message, the BRAS equipment returns a response message for the retransmitted discovery message, where the response message may be a response message of an acknowledgement or a response message of a negative acknowledgement. And after the user equipment receives the response message returned by the BRAS equipment, continuing the PPPOE negotiation flow according to the response message.
It can be seen that, in the message processing method of the embodiment of the present disclosure, after the user equipment sends the discovery message to the BRAS equipment, and after receiving a response message of a negative response returned by the BRAS equipment for the discovery message, a first delay time in the response message of the negative response is analyzed; after the first delay time, the discovery message is sent to the BRAS equipment again; and receiving a response message returned by the BRAS equipment aiming at the retransmitted discovery message. Therefore, after the first delay time, the user equipment resends the discovery message, the PPPOE negotiation process is delayed, and each step after the PPPOE negotiation process is delayed, so that the BRAS equipment delays to send the authentication request message to the AAA server, the processing pressure of the AAA server on the authentication request message when a large number of users are simultaneously on line is relieved, the congestion of the authentication request message at the AAA server is avoided, the authentication request message is smoothly processed, and the user experience is improved.
Referring to fig. 5, fig. 5 is another flowchart of a message processing method according to the embodiment of the present disclosure, including the following steps:
s501, sending a discovery message to BRAS equipment.
S502, if it is determined that the load of the AAA server exceeds the first preset threshold, returning a response packet for a negative response to the discovery packet, where the response packet includes a first delay time, so that the user equipment retransmits the discovery packet after the first delay time.
S503, resolving the first delay time in the response message of the negative response, and after the first delay time, resending the discovery message to the BRAS equipment.
S504, a response message for the retransmitted discovery message is returned.
As can be seen, fig. 5 is a flow chart of message interaction between the user equipment and the BRAS equipment, where the user equipment sends a discovery message to the BRAS equipment; if the BRAS equipment judges that the load of the AAA server exceeds a first preset threshold value, returning a response message aiming at the negative response of the discovery message; the user equipment analyzes the first delay time in the response message of the negative response, and after the first delay time, the discovery message is sent to the BRAS equipment again; and the BRAS equipment returns a response message aiming at the retransmitted discovery message. In the embodiment of the disclosure, in the PPPOE negotiation stage, that is, in the process of message interaction between the user equipment and the BRAS equipment, the BRAS equipment performs negative response on the discovery message, so that the user equipment resends the discovery message, thereby realizing delayed processing on the discovery message, further delaying the time for the BRAS equipment to send the authentication request message to the AAA server, reducing the processing pressure of the AAA server on the authentication request message when a large number of users are on-line concurrently, avoiding congestion of the authentication request message at the AAA server, enabling the authentication request message to be processed smoothly, and improving user experience.
Referring to fig. 6, fig. 6 is another flowchart of a message processing method according to the embodiment of the present disclosure, where an execution subject of each step in the embodiment of fig. 6 may be a BRAS device, and the method includes the following steps:
s601, obtaining the maximum value Q of the pre-established message countermaxThe message counter is used for counting the load of the AAA server, and according to a formula:
In the embodiment of the present disclosure, in order to conveniently count the load of the AAA server, the load of the AAA server is quantized, that is, the load of the AAA server may be the number of the authentication request messages or the accounting update request messages that have been sent to the AAA server but have not received a response from the AAA server, and the load of the AAA server may be counted by a message counter. Of course, the message counters for counting the number of the authentication request messages or the charging update request messages are different, but the method for determining one or more preset thresholds is the same, and here, the message counter of the authentication request message is taken as an example for description.
Wherein, the maximum value Q of the message countermaxIndicating the maximum pressure an AAA server can withstand for an authentication request message, i.e., during message processing,the value of the message counter cannot be greater than the maximum value Qmax. Generally, the higher the configuration of the AAA server, the maximum value Q of the message countermaxThe larger the maximum value Q can be determined according to the configuration of the AAA servermaxHere, Q is not pairedmaxThe determination method of (2) is defined.
In one implementation of the present disclosure, Q is determinedmaxThereafter, the following can be done according to the formula:
×Qmaxone or more preset thresholds are determined. Of course, this formula is only one implementation of the present disclosure, and other ways that one or more preset thresholds may be determined are within the scope of the present disclosure. For example, in another implementation of the present disclosure, the following may be expressed according to the formula:
alternatively, according to the formula:
one or more preset thresholds are determined, not to be enumerated here.
S602, receiving a discovery message sent by the user equipment.
S603, if it is determined that the load of the AAA server exceeds the first preset threshold, returning a response packet for a negative response to the discovery packet, where the response packet includes a first delay time, so that the user equipment retransmits the discovery packet after the first delay time.
In the embodiment of the present disclosure, the load of the AAA server may be counted by a message counter, the value of the message counter is constantly changed, and the calculation process of the value of the message counter specifically includes: when BRAS equipment sends an authentication request message to an AAA server, adding 1 to the value of a message counter; when the authentication request message sent to the AAA server is overtime, subtracting 1 from the value of the message counter; and when a response message sent by the AAA server aiming at the authentication request message is received, subtracting 1 from the value of the message counter. Judging that the load of the AAA server exceeds a first preset threshold, specifically: and judging that the load of the AAA server exceeds one or more than one preset threshold value in a plurality of preset threshold values, namely judging that the value of the message counter exceeds one or more than one preset threshold value in the plurality of preset threshold values.
In order to enable the AAA server to perform different time delay processing on the authentication request packet or the charging update request packet at different preset thresholds, each preset threshold may correspond to different delay times, that is, the user equipment may resend the discovery packet after different delay times, the BRAS device may perform different time delay processing on the discovery packet, and further enable the AAA server to perform different time delay processing on the authentication request packet or the charging update request packet. Generally, the magnitude of the delay time is positively correlated to the magnitude of the corresponding preset threshold. That is, the larger the preset threshold is, the larger the load of the AAA server is, and the smaller the processing capability of the AAA server for the authentication request packet or the charging update request packet is, then, when the BRAS device performs the delay processing on the discovery packet, a longer delay time may be set. The first delay time included in the response message is the delay time corresponding to the maximum preset threshold value in one or more preset threshold values.
For example, if QmaxHas a value of 10000 according to the formula:
if the value of n is 1, 2 and 3 respectively, the determined one or more preset thresholds are respectively: 5000. 7500 and 8750, and the preset thresholds 5000, 7500 and 8750 correspond to delay times of 5s, 10s and 20s, respectively.
If the current message counter is 9000, it is determined that the load of the AAA server exceeds 5000, 7500, and 8750, but the first delay time included in the response message is the delay time corresponding to the maximum preset threshold among the one or more preset thresholds, that is, the delay time 20s corresponding to the preset threshold 8750.
S604, if the discovery packet retransmitted by the ue is received before the first delay time arrives, determining whether the first delay time is less than a retransmission cycle of the retransmitted discovery packet.
In the embodiment of the present disclosure, after the user equipment receives a response message to a negative response to the discovery message returned by the BRAS device, if the user equipment agrees to resend the discovery message to the BRAS device when the first delay time arrives after analyzing the first delay time in the response message of the negative response, then the method for processing the message corresponds to the method steps in the embodiment of fig. 4. When the ue cannot resolve the first delay time in the negatively acknowledged response message, or the ue may resolve the first delay time in the negatively acknowledged response message, the ue does not intend to resend the discovery message after the first delay time, so that the ue resends the discovery message to the BRAS device before the first delay time arrives.
Because each discovery message sent by each user equipment has a certain retransmission cycle, the retransmission cycle of the discovery message sent by each user equipment can be different. After the BRAS equipment receives the discovery message retransmitted by the user equipment before the first delay time arrives, judging whether the first delay time is smaller than the retransmission cycle of the retransmitted discovery message. When the first delay time is judged to be not less than the retransmission cycle of the retransmitted discovery message, S605 is executed; when it is determined that the first delay time is less than the retransmission cycle of the retransmitted discovery packet, S606 is performed.
S605 cancels the processing for the retransmitted discovery packet.
In the embodiment of the disclosure, if the number of concurrent online users is particularly large, the congestion of the authentication request message sent by the BRAS device to the AAA server is particularly severe, the load of the AAA server exceeds a first preset threshold, and the first delay time corresponding to the first preset threshold already exceeds the retransmission cycle of the user device, if the BRAS device responds to the discovery message retransmitted by the user device in time, the user device still retransmits the discovery message when the retransmission cycle arrives (the time of the retransmission cycle arriving is earlier than the first delay time), instead of retransmitting the discovery message when the first delay time arrives, so the BRAS device can directly cancel the processing of the retransmitted discovery message, wait for the user device to retransmit the discovery message when the user device times out automatically, and thus can reduce unnecessary processing pressure of the BRAS device.
S606, after the second delay time, returning a response packet for the retransmitted discovery packet.
Specifically, when the first delay time is determined to be less than the retransmission cycle of the retransmitted discovery packet, that is, the time at which the first delay time arrives is earlier than the time at which the retransmission cycle arrives, the response packet for the retransmitted discovery packet may be returned after the second delay time, so that the user equipment may receive the response packet of the BRAS device earlier. The second delay time may be the same as the first delay time, or may be another delay time set according to S601, which is not limited herein.
In another implementation manner of the present disclosure, if the discovery packet retransmitted by the user equipment is received before the first delay time arrives, the first delay time and the retransmission cycle of the retransmitted discovery packet may not be determined, and after the second delay time, a response packet for the retransmitted discovery packet is returned.
In the message processing method provided by the embodiment of the present disclosure, after receiving a discovery message sent by a user equipment, when it is determined that a load of an AAA server exceeds a first preset threshold, a response message for a negative response to the discovery message is returned; and after receiving the discovery message retransmitted by the user equipment before the first delay time is reached, returning a response message aiming at the retransmitted discovery message after the second delay time when judging that the first delay time is less than the retransmission cycle of the retransmitted discovery message. And when the first delay time is judged to be not less than the retransmission cycle of the retransmitted discovery message, canceling the processing aiming at the retransmitted discovery message. According to the embodiment of the disclosure, when the load of the AAA server exceeds the first preset threshold, the discovery message sent by the user equipment is delayed, so that in the process of authenticating the user, the time for the BRAS equipment to send the authentication request message to the AAA server is delayed, the processing pressure of the AAA server on the authentication request message when a large number of users are simultaneously on line is reduced, the congestion of the authentication request message in the AAA server is avoided, the authentication request message is smoothly processed, and the user experience is improved.
As can be seen from the above, in the message processing method of the present disclosure, when the BRAS device responds to the user equipment, the response message includes the first delay time, and the user equipment is required to analyze the first delay time, that is, the user equipment is required to cooperate with the BRAS device. In another implementation manner of the present disclosure, the BRAS device directly performs delayed response to the discovery packet sent by the user device without the user device cooperating with the BRAS device. The method comprises the following steps:
the first step is to receive a discovery message sent by user equipment.
And step two, when the load of the AAA server is judged to exceed a third preset threshold value, after a fourth delay time, returning a response message aiming at the discovery message.
As can be seen, after receiving the discovery message sent by the user equipment, if it is determined that the load of the AAA server exceeds the third preset threshold, the BRAS device may return a response message for the discovery message after the fourth delay time. The setting method of the third preset threshold and the fourth delay time may be the same as that in the embodiment of fig. 6, and is not described herein again. Compared with the embodiment of fig. 3, the embodiment of the present disclosure does not require the cooperation of the user equipment, and the BRAS device can delay the response of the discovery message according to the judgment of the load of the AAA server, thereby delaying the time for the BRAS device to send the authentication request message to the AAA server, and reducing the processing pressure of the AAA server on the authentication request message.
