Description
Technical Field
The embodiment of the invention relates to the technical field of network communication, in particular to a network dialing method, a network dialing device and a storage medium.
Background
PPP (Point to Point Protocol) is a link layer Protocol and implements Point to Point communication. A whole set of scheme is provided in PPP protocol to solve the problems of link establishment, maintenance, removal, upper layer protocol negotiation, authentication and the like. The PPP Protocol is simple, has user authentication capability, can solve IP (Internet Protocol) address allocation, and is one of the most widely applied protocols in the current wide area network. PPPoE (Point to Point Protocol over Ethernet) utilizes Ethernet to form a network with a large number of hosts, a client is connected to the network through a remote server, and the server realizes control and charging functions for the accessed client. Because PPPoE has the characteristics of high cost performance, safety and convenience in authentication and charging management and the like, the PPPoE is widely applied to a series of applications such as community networking or community networking construction. At present, the most widely used broadband access method in a home is PPPoE, and PPP is responsible for establishing a communication link between a client and an access server of an operator.
At present, after PPP dialing successfully establishes a connection, a client usually sends a link detection request to a server, the server feeds back a corresponding answer after receiving the link detection request to verify whether the link is smooth, if the client does not receive the answer fed back by the server within a certain time period, or the client sends a specified number of link detection requests and does not receive the answer fed back by the server, the link is considered to be obstructed, the client actively terminates the link, and a new connection is initiated again. Or, the PPP server may also send a link detection request to the client, and the client feeds back a corresponding answer after receiving the link detection request, and if the server has sent a certain number of link detection requests and has not received a corresponding answer all the time, the server actively terminates the link, and the client needs to initiate a new connection request again. However, in reality, the PPP/PPPoE dial-up network environment is complex, for example, the PPP/PPPoE dial-up network may include a cell dial-up network or a community dial-up network, and the dial-up network of a small operator is not standard enough, some dial-up servers actively send link detection requests at fixed intervals, some dial-up servers send link detection requests at non-fixed intervals, other dial-up servers do not send link detection requests, some dial-up servers do not feed back corresponding answers, some dial-up servers occasionally feed back corresponding answers, and other dial-up servers are restarted at regular time. If the irregular server is dealt with according to the conventional dialing method, two disadvantages exist: firstly, a link detection request is sent to a server at regular time, if the answer of the server is not received, the client side is frequently disconnected and reconnected with the irregular PPP/PPPoE dialing server, and the network is unavailable; secondly, the client does not send a link detection request, so that when the link is abnormal (for example, when the server is restarted regularly or the server does not actively terminate abnormal connection according to the specification), the client does not sense the abnormality and does not initiate a dialing request again, thereby causing the unavailability of the network.
Therefore, there is a need for improvements to existing dialing methods to accommodate complex dialing network environments.

Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. 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.
Example one
Fig. 1 is a flowchart illustrating a network dialing method according to an embodiment of the present invention. The network dialing method provided by the embodiment can be executed by a network dialing device. Wherein the method may be implemented by software and/or hardware, may be generally integrated in a client, and more particularly, the client may be a home router. Referring specifically to fig. 1, the method comprises the steps of:
110. and when the session maintaining stage is entered between the client and the dial-up server, a link detection request is sent to the dial-up server based on the set frequency.
The method comprises the steps that before a client side is connected with a PPP/PPPoE dial-up network, a connection request is sent to a PPP/PPPoE dial-up server, after the dial-up server receives the connection request, PPPoED/PPP protocol interaction is carried out between the client side and the dial-up server, after a Discovery phase (PPPoED: PPPoE Discovery), LCP link negotiation, an authentication phase and an NCP negotiation phase, PPP/PPPoE session connection is successfully established, and a session holding phase is carried out between the client side and the dial-up server. In the session maintaining stage, the client sends a link detection request to the dial-up server based on the set frequency to detect whether the current link communication is normal. Specifically, the link detection Request may be an LCP Echo Request, and if the current link communication is normal, the dial-up server may correspondingly feed back answer information LCP Echo Reply after receiving the LCP Echo Request, so that as long as the LCP Echo Reply fed back by the dial-up server is received, it may be determined that the link communication between the client and the dial-up server is normal.
120. When the number of the link detection requests sent to the dial-up server exceeds a threshold value, if the answer information fed back by the dial-up server aiming at the link detection requests or the link detection information sent by the dial-up server is not received, executing a preset internet access task.
At present, some dial servers have a link detection function, and after a session holding stage is performed between a client and the dial server, the dial server actively sends link detection information LCP Echo Request to the client, so that if the client only receives the LCP Echo Request sent by the dial server, it can also be determined that link communication between the client and the dial server is normal.
Because the actual dial-up network environment is complex, various irregular PPP/PPPoE dial-up servers managed by small operators exist, some irregular dial-up servers do not feed back corresponding answer information LCP Echo Reply to the client even if receiving a link detection Request LCP Echo Request from the client, and under the condition, the client cannot always receive the corresponding LCP Echo Reply, the link communication between the client and the dial-up server is determined to be abnormal, the client can disconnect the current link and resend the dial-up Request again, so that the client frequently disconnects the link and reconnects, and the client network is unavailable. In some cases, the LCP Echo Request sent by the client or the LCP Echo Reply fed back by the dial-up server is lost due to network interference and other factors, and the client may also consider that the current link communication is abnormal, resulting in a misjudgment.
In view of the above problems, in this embodiment, a certain number of link detection requests are sent to a dial-up server, so as to eliminate the situation of packet loss as much as possible, and if the number of link detection requests sent to the dial-up server exceeds a threshold value, a preset internet access task is executed if reply information fed back by the dial-up server in response to the link detection requests is not received, so as to eliminate an irregular PPP/PPPoE dial-up server managed by a small operator by the dial-up server.
Specifically, the preset internet surfing task comprises: DNS domain name resolution and/or NTP time synchronization.
Correspondingly, the executing of the preset internet surfing task comprises the following steps:
acquiring a preset domain name from a DNS configuration file, and performing domain name resolution on the domain name;
in order to eliminate the domain name abnormality, for example, the number of the preset domain names is at least two, and if one of the preset at least two domain names is successfully analyzed, it is determined that the link communication between the client and the dial-up server is normal.
Further, before performing domain name resolution on the domain name, the method further includes:
and clearing the DNS cache of the client to ensure that the domain name resolution is carried out by the occurrence of network communication behavior, rather than directly acquiring the IP address corresponding to the domain name from the local DNS cache of the client.
Typically, the preset domain name may bewww.qq.com、www.baidu.com、www.google.comOrwww.microsoft.com。
130a, if the preset internet task is successfully executed, determining that the link communication between the client and the dial-up server is normal, and maintaining the current link between the client and the dial-up server.
If the domain name resolution is successful or the NTP time synchronization is successful, the client can perform normal network behavior, the current link between the client and the dial-up server is normally communicated, and the current link between the client and the dial-up server is continuously maintained without disconnection and reconnection, so that the network of the client is ensured to be normal.
130b, if the preset internet task fails to be executed, determining that the link communication between the client and the dialing server is abnormal, terminating the current link between the client and the dialing server, and re-initiating a dialing request to the dialing server.
If the domain name resolution fails or the domain name resolution fails and the NTP time synchronization also fails, the client side cannot perform normal network behaviors, and the current link communication between the client side and the dialing server is really abnormal, the current link between the client side and the dialing server is terminated, and a dialing request is initiated to the dialing server again.
The network dialing method provided by the embodiment can ensure that the link detection behaviors of the PPP/PPPoE dialing server which are adapted normally and abnormally are compatible under the complex PPP/PPPoE dialing network environment, ensure that various dialing networks can be normal, and can not only detect abnormal redialing of the link but also ensure that the normal link is prevented from being judged mistakenly as the abnormal link so as to cause the redialing of the normal network aiming at the server which does not respond to PPPLCP Echo Reply according to the standard, thereby realizing the purpose of accurately identifying whether the current communication link is unblocked so as to ensure that the client network is normal.
Example two
Fig. 2 is a flowchart illustrating a network dialing method according to a second embodiment of the present invention. On the basis of the above embodiments, the present embodiment provides an implementation manner in which the number of link detection requests transmitted to the dial server is counted by the timeout counter. The system can conveniently know the total number of the link detection requests sent to the dialing server by setting the timeout counter. Referring specifically to fig. 2, the method specifically includes the following steps:
210. and entering a session holding phase between the client and the dialing server.
220. And sending a link detection request to the dialing server based on the set frequency, and increasing the counting value of the timeout counter by 1 every time the link detection request is sent to the dialing server.
230. And when the count value in the overtime counter reaches 2, if the answer information fed back by the dialing server aiming at the link detection request is not received, executing a preset internet access task.
The threshold value reached by the count value in the timeout counter may be set according to actual conditions, and is not limited to 2, and in this embodiment, only 2 is used as an example for explanation, and is not limited thereto.
240. And when the count value in the overtime counter reaches 3, if the answer information fed back by the dialing server aiming at the link detection request is not received, judging the execution result of the internet surfing task.
The method comprises the steps that a preset internet access task needs to be executed for a certain time, a set frequency is still kept to send a link detection request to a dialing server in the period, when the count value in the timeout counter reaches 3, if answer information fed back by the dialing server according to the link detection request is not received, the execution result of the internet access task is judged, and if the answer information fed back by the dialing server according to the link detection request is received, the link communication between a client and the dialing server can be directly determined to be normal.
250a, if the preset internet task is successfully executed, determining that the link communication between the client and the dial-up server is normal, clearing the counting value of the timeout counter, returning to the step 220, and continuing the link detection process.
250b, if the preset internet task fails to be executed, determining that the link communication between the client and the dialing server is abnormal, terminating the current link between the client and the dialing server, and re-initiating a dialing request to the dialing server.
Correspondingly, referring to a schematic diagram of a network dialing system architecture shown in fig. 3, taking the preset internet surfing task as DNS domain name resolution and NTP time synchronization as an example, a link detection module of the client specifically includes a DNS detection module and an NTP detection module. When a session holding stage is started between a client and a dial-up server, a link detection module sends a link detection request to the dial-up server based on a set frequency, when the number of the link detection requests sent to the dial-up server exceeds a threshold value, if answer information fed back by the dial-up server aiming at the link detection request or link detection information sent by the dial-up server is not received yet, a DNS detection module and an NTP detection module are started, the DNS detection module acquires a preset typical domain name from a DNS configuration file to perform domain name resolution, the NTP detection module is responsible for realizing NTP time synchronization, and if any one of the DNS detection module and the NTP detection module succeeds, the link communication between the client and the dial-up server is determined to be normal.
In the network dialing method provided by the embodiment, in the detection of the LCP Echo Request and LCP Echo Reply, the DNS domain name resolution and the NTP time synchronization are combined, so that whether the current communication link is smooth is accurately identified, and the purpose of ensuring that the client network is normal is achieved.
