in particular, a public network may refer to a wide area network, which is a remote network connecting computers communicating over local or metropolitan area networks in different regions. Typically spanning a large physical range, ranging from tens of kilometers to thousands of kilometers, and which can connect multiple regions, cities and countries, or span several continents and provide long-range communications, forming an international long-range network. The fixed private line is a symmetric telecommunication line for connecting two areas, and unlike the traditional PSTN, the fixed private line has no telephone number, and permanent connection is established at both ends of the private line, and the fixed private line can be applied to telephone, data and Internet services. And a special line access service node cluster is provided for the user, so that the stability and the safety of connection can be effectively improved. The content Delivery network may be a CDN (content Delivery network), which is an intelligent virtual network constructed on the basis of an existing network, and enables a user to obtain required content nearby by means of functional modules of load balancing, content Delivery, scheduling and the like of a central platform by means of edge servers deployed in various places, so that network congestion is reduced, and the access response speed and hit rate of the user are improved. The content delivery network connection in the embodiment of the present application refers to providing an access function of a target service node for a user by using a CDN global service and using a coverage node and a back-to-source link of the CDN. Preferably, because a single CDN has limited access devices in different regions and is prone to failure, multiple CDN vendors can be accessed simultaneously, so that stability and security of connection are improved. The selectable connection modes comprise at least two of public network connection, content distribution network connection and private line connection, so that one connection mode can be automatically switched to the other connection mode when one connection fails or is abnormal, and the stability of the user accessing the target service node is improved.
Preferably, the determining the optional connection mode for accessing the target node according to the access amount data of the area where the user is located, for example, the determining the optional connection mode according to the access amount data of the area where the user is located includes: when the access volume data is greater than or equal to a first threshold value, the selectable connection modes comprise private line connection, content distribution network connection and public network connection; when the access data is less than the first threshold, the selectable connection modes comprise content distribution network connection and public network connection. When the access amount of an area is greater than or equal to the first threshold, a fixed connection private line can be directly established between the area and the service node cluster, so that the stability and the safety of user connection in the area are improved. Optionally, the first threshold may be a median of the global regional visit volume data, may also be a minimum of the first 30% global regional visit volume data, and may also be a minimum of the first 40% global regional visit volume data, which is not specifically limited in this application.

More connection modes can be set for the high-access area, so that users in the high-access area can normally access the service node cluster.
S102: the latency of accessing the target service node in each of the selectable connection modes is tested.
S103: setting a priority for the connection modes in the selectable connection modes, wherein the target service node is accessed in each connection mode in the selectable connection modes, and the lower the delay of the connection mode is, the higher the set priority is;
specifically, the optional connection mode with the lowest access delay in the optional connection modes may be used as the optional connection mode with the highest priority, the optional connection mode with the second lowest access delay in the optional connection modes may be used as the optional connection mode with the second highest priority, and so on, the optional connection mode with the highest access delay in the optional connection modes may be used as the optional connection mode with the lowest priority, and the target service node is accessed through the connection mode with the highest priority in the optional connection modes, which is favorable for reducing the deployment cost and the maintenance cost of the service node cluster on the premise of ensuring the access quality of the user.

when line jitter or line interruption occurs in the process of accessing the target service node through the connection mode with the highest priority in the selectable connection modes, switching to accessing the target service node through the connection mode with the next priority in the selectable connection modes.
Specifically, when the target service node is accessed in the connection mode with the highest priority in the optional connection modes and fails or is abnormal, the target service node is accessed in the connection mode with the second highest priority in the optional connection modes, when the target service node is accessed in the connection mode with the second highest priority in the optional connection modes and fails or is abnormal, the target service node is accessed in the connection mode with the third highest priority in the optional connection modes, and the like until the target service node is accessed successfully. Similarly, when the target service node is accessed by the connection mode with the highest priority in the optional connection modes and line jitter or line interruption occurs, the target service node is accessed by the connection mode with the second highest priority in the optional connection modes, when the target service node is accessed by the connection mode with the second highest priority in the optional connection modes and line jitter or line interruption occurs, the target service node is accessed by the connection mode with the third highest priority in the optional connection modes, and so on until the access is successful. Therefore, when the access of the user fails, the access is abnormal, and line jitter or line interruption occurs, the target service node access method provided by the embodiment of the application can enable the user to finally successfully access the resource of the target service node by continuously and automatically switching the connection mode of the sub-priority, so that the use experience of the user is greatly improved.

In particular, load balancing is a computer technique used to distribute load among multiple computers (computer clusters), network connections, CPUs, disk drives, or other resources for the purpose of optimizing resource usage, maximizing throughput, minimizing response time, while avoiding overload. Using multiple server components with load balancing, instead of a single component, may increase reliability through redundancy. The load balancing service is usually completed by dedicated software and hardware, and the main role is to reasonably distribute a large amount of jobs to a plurality of operation units for execution, so as to solve the problems of high concurrency and high availability in the internet architecture. In the embodiment of the application, the load balancing technology is applied to the service node cluster, so that the service instances in the service node cluster can be transversely expanded, the maintenance is more convenient, even the automatic expansion and contraction according to the quantity can be realized, and the zero maintenance is realized.

Optionally, obtaining the optional connection mode according to the access amount data may further include: obtaining an optional connection mode according to the visit quantity data and the visit quality of the area, which specifically comprises the following steps: when the ratio of the number of complaints of the client in the area to the access volume data is greater than or equal to a second threshold value, the selectable connection modes comprise private line connection, content distribution network connection and public network connection; and when the proportion of the number of complaints of the customers to the access volume data in the area is smaller than a second threshold value, the selectable connection modes comprise content distribution network connection and public network connection. Alternatively, the second threshold may be set manually as needed. The region where the user is located may be a country or a continent, which is not limited in the present application. More connection modes can be set for the high-access area, so that users in the high-access area can normally access the service node cluster.
The latency of accessing the target service node in each of the selectable connection modes is tested.
Setting a priority for the connection modes in the selectable connection modes, wherein the target service node is accessed in each connection mode in the selectable connection modes, and the lower the delay of the connection mode is, the higher the set priority is;
specifically, the optional connection mode with the lowest access delay in the optional connection modes may be used as the optional connection mode with the highest priority, the optional connection mode with the second lowest access delay in the optional connection modes may be used as the optional connection mode with the second highest priority, and so on, the optional connection mode with the highest access delay in the optional connection modes may be used as the optional connection mode with the lowest priority, and the target service node is accessed through the connection mode with the highest priority in the optional connection modes, which is favorable for reducing the deployment cost and the maintenance cost of the service node cluster on the premise of ensuring the access quality of the user.
And accessing the target service node through the connection mode with the highest priority in the selectable connection modes.
Optionally, in a specific embodiment, the method further includes:
and when the target service node is accessed in the connection mode in the optional connection mode fails or is abnormal, switching to the connection mode with the next priority in the optional connection mode to access the target service node.
Optionally, in a specific embodiment, the method further includes:
when line jitter or line interruption occurs in the process of accessing the target service node through the connection mode with the highest priority in the selectable connection modes, switching to accessing the target service node through the connection mode with the next priority in the selectable connection modes.
Specifically, when the target service node is accessed in the connection mode with the highest priority in the optional connection modes and fails or is abnormal, the target service node is accessed in the connection mode with the second highest priority in the optional connection modes, when the target service node is accessed in the connection mode with the second highest priority in the optional connection modes and fails or is abnormal, the target service node is accessed in the connection mode with the third highest priority in the optional connection modes, and the like until the target service node is accessed successfully. Similarly, when the target service node is accessed by the connection mode with the highest priority in the optional connection modes and line jitter or line interruption occurs, the target service node is accessed by the connection mode with the second highest priority in the optional connection modes, when the target service node is accessed by the connection mode with the second highest priority in the optional connection modes and line jitter or line interruption occurs, the target service node is accessed by the connection mode with the third highest priority in the optional connection modes, and so on until the access is successful. Therefore, when the access of the user fails, the access is abnormal, and line jitter or line interruption occurs, the target service node access method provided by the embodiment of the application can enable the user to finally successfully access the resource of the target service node by continuously and automatically switching the connection mode of the sub-priority, so that the use experience of the user is greatly improved.
Optionally, in a specific embodiment, service nodes located in different regions around the world are deployed collectively as a service node cluster;
specifically, the service node cluster may be a server cluster, where a server cluster refers to a cluster of many servers that are collected together to perform the same service, and appears to the client as if there is only one server. The cluster can use a plurality of computers to perform parallel computation so as to obtain high computation speed, and can also use a plurality of computers to perform backup so as to ensure that any one machine damages the whole system or can normally run. In this way, the deployment cost and maintenance cost of the target service node can be reduced.
Optionally, in a specific embodiment, the method further comprises:

Optionally, in a specific embodiment, the method further comprises:
load balancing techniques are applied to the cluster of service nodes.
In particular, load balancing is a computer technique used to distribute load among multiple computers (computer clusters), network connections, CPUs, disk drives, or other resources for the purpose of optimizing resource usage, maximizing throughput, minimizing response time, while avoiding overload. Using multiple server components with load balancing, instead of a single component, may increase reliability through redundancy. The load balancing service is usually completed by dedicated software and hardware, and the main role is to reasonably distribute a large amount of jobs to a plurality of operation units for execution, so as to solve the problems of high concurrency and high availability in the internet architecture. In the embodiment of the application, the load balancing technology is applied to the service node cluster, so that the service instances in the service node cluster can be transversely expanded, the maintenance is more convenient, even the automatic expansion and contraction according to the quantity can be realized, and the zero maintenance is realized.

Thus, particular embodiments of the present subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.

In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
