101. and receiving an application access request, and forwarding the application access request to the content switching virtual machine through a preset application switch.

The application access request is used to indicate a service operation uniform resource locator sent by one or more terminals, for example, the application access request may be used to request an online medical service, a medical and electronic commerce service, and may also be used to request a health education service, which is not limited herein. The preset application switch is used for intercepting and verifying the application access request, and the preset application switch may be a hardware load balancing switch netscaler or other load balancing switches, which is not limited herein. The content exchange virtual machine is used for carrying out load balancing processing on the application access request. Specifically, the server receives an application access request and acquires terminal address information; the server judges whether a preset network protocol address information table has terminal address information or not; if the preset network protocol address information table has terminal address information, the server forwards the terminal address information to a content exchange virtual machine through a preset application switch, and the content exchange virtual machine is used for indicating to perform domain name resolution and load balancing processing on the application access request. For example, when the application access request sent by the terminal is http:// srv. pajk-ent.com/timer, and the http:// srv. pajk-ent.com/timer reaches a hardware load balancing switch (i.e., a preset application switch) netscaler in the server, the server performs verification and/or forwarding processing on the application access request through the netscaler.

It is to be understood that the execution subject of the present invention may be a load balancing processing apparatus, and may also be a terminal or a server, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.

102. The converged domain name address and the redirection address are extracted from the application access request by the content exchange virtual machine.

The application side inquiry request may be a get request mode or a post request sending mode, and is not limited herein. The application access request includes a converged domain name address, a redirection address, and parameter information. For example, when the application access request is in a get request mode, the application access request is http:// srv. Specifically, the server acquires the application access request through a preset full path acquisition function, where the preset full path acquisition function may be a request. Then, the server resolves the application access request according to the hypertext transfer protocol by a content exchange virtual machine (for example, cs _1b) to obtain a convergence domain name address and a redirection address, wherein the convergence domain name address is srv.

103. And matching and analyzing the strategy binding rules corresponding to the content exchange virtual machine according to the convergence domain name address and the redirection address to obtain a target load forwarding strategy, wherein the strategy binding rules corresponding to the content exchange virtual machine comprise a plurality of load forwarding strategies and a plurality of pattern matching data sets, and each load forwarding strategy corresponds to each pattern matching data set one by one.

Wherein, the content exchange virtual machine is used for realizing seven-layer load balancing. Specifically, the server sets a plurality of policy identifiers and a plurality of pattern identifiers according to a convergent domain name address and according to a preset policy generation rule and a preset pattern generation rule, the server performs matching analysis on policy binding rules corresponding to the content exchange virtual machine according to the policy identifiers and the pattern identifiers to obtain a plurality of load forwarding policies and a plurality of pattern matching data sets, and each load forwarding policy location corresponds to each pattern matching data set patset one by one, for example, the server establishes a vm patset for a location where a certain domain name needs to access a virtual machine service type vm, and establishes a k8s patset for a location where a container service type k8s needs to be accessed; the server accesses each load forwarding policy in a traversal manner from low to high according to the priority corresponding to each load forwarding policy, and when a pattern matching data set corresponding to each load forwarding policy contains a redirection address, the server determines that the load forwarding policy corresponding to the pattern matching data set is a target policy (i.e., a target load forwarding policy) to obtain a target policy identifier, where the target policy identifier may be a name of each load forwarding policy. Further, the server stores the policy binding rule in a blockchain database, which is not limited herein.

104. And forwarding the application access request to a target virtual host according to a target load forwarding strategy, forwarding the application access request to a target reverse proxy through the target virtual host, and performing load balancing processing on the application access request through the target reverse proxy.

The target virtual host belongs to a netscaler, and includes a virtual host of a virtual machine service type vm and a virtual host of a container service type k8s (i.e., kubernets), and the target virtual host can be used to serve operators. Specifically, the server performs load forwarding processing on the application access request according to a target load forwarding policy and a target pattern matching data set patset (that is, the server determines a target virtual host from a plurality of virtual hosts), and when the target virtual host receives the application access request, the server forwards the application access request to a target reverse proxy (e.g., ingress or nginx) through the target virtual host, where the target virtual host and the target reverse proxy are in one-to-one correspondence, for example, a target reverse proxy corresponding to a vm-type target virtual host is vm/nginx, and a target reverse proxy corresponding to a k8 s-type target virtual host is k8 s/ingress; then, the server performs load balancing processing on the application access request through the target reverse proxy.

In the embodiment of the invention, the content is forwarded to the content exchange virtual machine through a preset application switch; matching and analyzing a strategy binding rule corresponding to the content exchange virtual machine according to the convergence domain name address and the redirection address to obtain a target load forwarding strategy; and forwarding the application access request to a target virtual host according to a target load forwarding strategy, forwarding the application access request to a target reverse proxy through the target virtual host, and performing load balancing processing on the application access request through the target reverse proxy. And the virtualization technology is smoothly switched and applied according to the service requirements, so that the load balancing network link is shortened, and the network performance loss is reduced. This scheme can be applied to in the wisdom medical field to promote the construction in wisdom city.

Referring to fig. 2, another embodiment of the load balancing method according to the embodiment of the present invention includes:

201. acquiring a convergence domain name address and a service type, adding at least one pattern matching data set according to the convergence domain name address and the service type, and performing data initialization on the at least one pattern matching data set.

Specifically, the server sets a set name corresponding to at least one pattern matching data set patset according to the convergence domain name address and the service type, wherein the set name is used for indicating that the prefix, the convergence domain name address and the suffix are combined in a' splicing mode. The prefix may be p or policy, and is not specifically limited herein, and the suffix is a service type. Optionally, a converged domain name address may correspond to two sets of patset data, for example, the server performs add policy patset p _ testk8s _ dev _ pajkdc _ com _ vm to create a first set of pattern matching data named testk8s _ dev _ pajkdc _ com _ vm for storing domain name location under the domain name that needs to be forwarded to vm/nginx; or the server executes add policy patset p _ testk8s _ dev _ pajkdc _ com _ k8s for creating a second set of pattern matching data named testk8s _ dev _ pajkdc _ com _ k8s for storing the domain name location at the domain name that needs to be forwarded to k8 s/ingress. Then, the server initializes at least one pattern matching data set (e.g., a patset data set), that is, the server assigns a corresponding redirection address (redirection address is character string data) to the patset data set. When there is an add-drop-and-delete operation for an application, or vm and k8s migrate, it is sufficient for the server to maintain both patset data sets.

202. And setting at least one load forwarding strategy according to the convergence domain name address and the service type, and associating and binding each load forwarding strategy and each pattern matching data set.

Specifically, the server sets a policy name corresponding to each load forwarding policy according to the convergence domain name address and the service type, wherein the policy name is used for indicating that a prefix, the convergence domain name address and a suffix are spliced and combined according to a _'; then, the server sets at least one load forwarding strategy according to the strategy name corresponding to each load forwarding strategy, and associates and binds each load forwarding strategy and each pattern matching data set. The prefix may be a null value or other values, which is not specifically limited herein, and the suffix is a service type. One converged domain name address may set three load forwarding policies:

add cs policy srv_pajk-ent_com_VM-rule

"HTTP.REQ.HOSTNAME.EQ(\"srv.pajk-ent.com\")&&

HTTP.REQ.URL.PATH.GET(1).set_text_mode(IGNORECASE).EQUALS_ANY(\"p_srv_pajk-ent_com_VM\")；

the instruction is used to create a first load forwarding policy srv _ pajk-ent _ com _ VM that handles only the p _ srv _ pajk-ent _ com _ VM domain name, and that first location belongs to the signature created VM patset of data (i.e., p _ srv _ pajk-ent _ com _ VM).

add cs policy srv_pajk-ent_com_k8s-rule

"HTTP.REQ.HOSTNAME.EQ(\"srv.pajk-ent.com\")&&

HTTP.REQ.URL.PATH.GET(1).set_text_mode(IGNORECASE).EQUALS_ANY(\"p_srv_pajk-ent_com_k8s\")；

The instructions are used to create a second load forwarding policy srv _ pajk-ent _ com _ k8s that handles only the srv _ pajk-ent _ com _ k8s domain name, and the first location of which belongs to the signature built k8s patset of data (i.e., p _ srv _ pajk-ent _ com _ k8 s).

add cs policy srv_pajk-ent_com_Default-rule

"HTTP.REQ.HOSTNAME.EQ(\"srv.pajk-ent.com\")&&

HTTP.REQ.URL.STARTSWITH(\"/\")"；

The instructions are for creating a third load forwarding policy srv _ pajk-ent _ com _ Default for handling srv.

203. And performing associated mapping processing on each load forwarding strategy, the content exchange virtual machine and the target virtual host, and distributing a corresponding priority value to each load forwarding strategy according to a preset priority distribution rule.

The server sets a priority for each load forwarding policy to implement a policy matching sequence by binding the priority specified when each load forwarding policy is bound. For example, the server sets vm to match first, k8s times match, and default last. The specific binding process is as follows:

bind cs vserver cs_lb–policyName srv_pajk-ent_com_vm-targetLBVserver vm_lb-priority 1；

the server executes the instruction to bind the first load forwarding policy srv _ pajk-ent _ com _ vm to the content exchange virtual machine cs _ lb, and the server transfers the traffic reaching the cs _ lb to the target virtual host vm _ lb and gives the highest priority value 1.

bind cs vserver cs_lb-policyName srv_pajk-ent_com_k8s-targetLBVserver k8s_lb-priority 2；

The server executes the instruction to bind the second load forwarding policy srv _ pajk-ent _ com _ k8s to the content exchange virtual machine cs _ lb, the server diverts traffic arriving at cs _ lb to the target virtual host k8s _ lb and assigns a next highest priority value of 2.

bind cs vserver cs_lb-policyName testk8s_dev_pajkdc_com_default-targetLBVserver vm_lb-priority 3；

The server executes the instruction to bind the third load forwarding policy testk8s _ dev _ pajkdc _ com _ default to the content switching virtual machine cs _ lb, and the server transfers the traffic arriving at the cs _ lb to the target virtual host vm _ lb and gives the lowest priority value of 3.

It should be noted that the cs _ lb may be a content exchange virtual machine corresponding to a certain operator, and is used to abstract three groups of virtual hosts into one combination. When the flow reaches cs _ lb, the server performs logic operation according to a preset operation rule through the cs _ lb, the preset operation rule is that a load forwarding strategy with low priority is matched first, and when the matching is successful, the server transfers the application access request to the matched load forwarding strategy targetLBVserver. The server binds the patset data set to the corresponding load forwarding policy so that the patset data set (i.e., the pattern matching data set) is validated. The server establishes three pattern matching data sets and three load forwarding strategies, namely, a vm set and a vm strategy, a k8s set and a k8s strategy, and a default set, wherein the default set adopts a default strategy for a character string "/"), associates the three pattern matching data sets and the three load forwarding strategies one by one, and finally, binds the one-to-one associated load forwarding strategies and the one-to-one associated pattern matching data sets to the same content exchange virtual machine.

204. And receiving an application access request, and forwarding the application access request to the content switching virtual machine through a preset application switch.

Further, the server identifies that the connection mode with the terminal is a hypertext transfer protocol proxy mode or a load balancing mode through a request header field XFF (namely, X-Forwarded-For); if the connection mode with the terminal is a hypertext transfer protocol proxy mode, the server calls a preset address to obtain a function request. If the connection mode with the terminal is a load balancing mode, the server acquires the request header field through the firewall and extracts the terminal address information from the request header field. Optionally, the server receives the application access request, intercepts the application access request through a preset application switch, and acquires the terminal address information; the server judges whether the application access request is abnormal or not according to the terminal address information, specifically, the server judges whether the terminal address information exists in a preset network protocol address information table or not, if the terminal address information does not exist in the preset network protocol address information table, the server determines that the application access request is abnormal, and if the terminal address information exists in the preset network protocol address information table, the server determines that the application access request is normal; if the application access request is abnormal, the server generates and records request abnormal information and sends the request abnormal information to the terminal, and further the terminal displays the request abnormal information and prompts that the access authority of the target user terminal is limited; if the application access request is not abnormal, the server forwards the application access request to the content exchange virtual machine through a preset application switch according to a preset binding relationship, wherein the preset binding relationship is used for indicating association mapping between the content exchange virtual machine and the preset application switch.

205. The converged domain name address and the redirection address are extracted from the application access request by the content exchange virtual machine.

Further, the server may further obtain the converged domain name address through a preset hostname obtaining function getRemoteHost (). Then the server obtains a rule to be checked corresponding to the convergence domain name address; the server checks the convergence domain name address according to the rule to be checked; and if the convergence domain name address does not pass the check, the server generates and records check failure information. Optionally, the server sets a uniform resource location object to the application access request according to a preset constructor through the content exchange virtual machine, and calls a domain name obtaining function based on the uniform resource location object to obtain a convergence domain name address; and the server extracts the redirection address from the application access request according to a preset regular matching rule, wherein the preset regular matching rule is used for indicating character matching and segmentation processing of the application access request.

For example, the application access request A is http:// srv. pajk-ent.com/timeline, the application access request B is http:// srv. pajk-ent.com/timeline/hellowrod.html, the application access request C is http:// srv. pajk-ent.com/timeline/hellowrod.htmlparam ═ 1, and the server performs character matching and segmentation processing on the application access request A, the application access request B and the application access request C respectively according to a preset regular matching rule to obtain the redirection addresses which are the timelines. Further, the server can also perform character case unified processing on the converged domain name address and the redirection address.

206. And matching and analyzing the strategy binding rules corresponding to the content exchange virtual machine according to the convergence domain name address and the redirection address to obtain a target load forwarding strategy, wherein the strategy binding rules corresponding to the content exchange virtual machine comprise a plurality of load forwarding strategies and a plurality of pattern matching data sets, and each load forwarding strategy corresponds to each pattern matching data set one by one.

That is, the server preferentially selects the load forwarding policy with low priority for policy matching, and further, the server may also sequentially access each domain name policy from low to high according to the priority value corresponding to each load forwarding policy. The pattern matching data set patset corresponding to each load forwarding policy is a character string data set, may be used to store any unrepeated character string, and is mainly used to store a redirection address location of a converged domain name address, where the location is a first character string of a slash/character partition in a uniform resource locator url, and a converged domain name address corresponds to multiple application programs.
