Technical Field

The present invention relates to the field of communications technologies, and in particular, to a system, a method, and an apparatus for processing a service request.

Background

With the rapid development of network technology, service requests of clients can be processed based on an SDP (Software Defined Perimeter) architecture. The SDP architecture may include: the system comprises a client, a controller, a plurality of gateways and a plurality of service servers.

Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.

In the related art, the SDP architecture may include: the system comprises a client, a controller, a plurality of gateways and a plurality of service servers. The service servers corresponding to the gateways are different, and when the performance of a certain gateway is reduced, the processing efficiency of all service requests for the service server corresponding to the gateway is reduced, so that the performance of the SDP architecture is not high.

In order to solve the above problem, an embodiment of the present invention provides a service request processing system. Referring to fig. 1, fig. 1 is a framework of a networking according to an embodiment of the present invention, where the networking includes: the system comprises a controller 102, a client 101, a plurality of preset gateways (including a preset gateway 1031, a preset gateway 1032, a preset gateway 1033 and a preset gateway 1034), and a plurality of service servers (including a service server 1041, a service server 1042, a service server 1043 and a service server 1044). The embodiment of the present invention is described by taking an example including 4 preset gateways and 4 service servers, and is not limited to this.

Correspondingly, the service request processing system provided by the embodiment of the present invention may include: a controller 102, a client 101, and a target gateway (the target gateway may be any one of the plurality of preset gateways described above). Accordingly, the target service server mentioned in the embodiment of the present invention may be any one of the plurality of service servers described above.

As can be seen from fig. 1, each service server corresponds to a plurality of preset gateways (i.e., alternative gateways in the embodiment of the present invention). The alternative gateways corresponding to the service server 1041 include a preset gateway 1031 and a preset gateway 1033; the alternative gateways corresponding to the service server 1042 include a preset gateway 1031, a preset gateway 1032 and a preset gateway 3; the alternative gateways corresponding to the service server 1043 include a preset gateway 1031 and a preset gateway 1032; the alternative gateways corresponding to the service server 1044 include a preset gateway 1033 and a preset gateway 1034.

A client 101, configured to send a domain name resolution request for a target service server to the controller 102.

The controller 102 is configured to determine, according to a current first access delay between the client 101 and each alternative gateway corresponding to a target service server in each gateway, and/or a current second access delay between each alternative gateway and the target service server, a target gateway that meets a preset condition from each alternative gateway; the network address of the target gateway is sent to the client 101.

The client 101 is further configured to send a service request for the target service server to the target gateway based on the network address.

In the system of the embodiment of the present invention, one service server may correspond to a plurality of candidate gateways in the preset gateways, and the controller may determine a target gateway satisfying a preset condition from the plurality of candidate gateways based on an access delay between the client and the candidate gateway and/or an access delay between the candidate gateway and the service server. That is to say, the controller may determine the target gateway based on the performance of the alternative gateways, and if the performance of a certain alternative gateway is degraded, may select another alternative gateway as the target gateway to forward the service request, so as to avoid processing by the degraded alternative gateway, and further, may improve the processing efficiency of the service request, and improve the performance of the SDP framework.

For further embodiments of the client 101, the controller 102 and the target gateway in the above system, reference may be made to the following detailed description of embodiments of the client, controller and target gateway methods.

The invention provides a service request processing method, which can be applied to a controller, and the controller can be the controller 102 in the system.

Referring to fig. 2, fig. 2 is a flowchart of a service request processing method provided by an embodiment of the present invention, and the method is applied to a controller, and the method may include the following steps:

s201: receiving a domain name resolution request aiming at a target service server sent by a client.

S202: and determining the target gateway meeting the preset conditions from the alternative gateways according to the current first access time delay between the client and the alternative gateways corresponding to the target service servers in the preset gateways and/or the current second access time delay between each alternative gateway and the target service server.

S203: and sending the network address of the target gateway to the client, so that the client sends a service request aiming at the target service server to the target gateway based on the network address, so that the target gateway sends the service request to the target service server, and the target service server responds to the service request.

In the method of the embodiment of the invention, one service server can correspond to a plurality of alternative gateways in the preset gateways, and the controller can determine the target gateway meeting the preset condition from the plurality of alternative gateways based on the access time delay between the client and the alternative gateways and/or the access time delay between the alternative gateways and the service server. That is to say, the controller may determine the target gateway based on the performance of the alternative gateways, and if the performance of a certain alternative gateway is degraded, may select another alternative gateway as the target gateway to forward the service request, so as to avoid processing by the degraded alternative gateway, and further, may improve the processing efficiency of the service request, and improve the performance of the SDP framework.

In step S201, the controller is configured to resolve the domain name of each service server. When a user needs to access one service server (i.e. a target service server in the embodiment of the present invention) through a client, the client may send a domain name resolution request including a target domain name of the target service server to the controller.

In one implementation manner, an accessible service navigation page may be displayed in the client, where the accessible service navigation page includes multiple authority identifiers, and each authority identifier corresponds to a service server having an access authority of the client. For example, one authority identifier may be an icon of the corresponding service server. When the user clicks on the icon, the client may determine that the user selects to access the service server represented by the icon, and send a domain name resolution request for the service server to the controller.

In step S202, one service server corresponds to a plurality of gateways (i.e., alternative gateways) in the preset gateways, that is, the client may access the service server through any alternative gateway corresponding to the service server. Therefore, if the performance of a certain alternative gateway corresponding to the service server is degraded, another alternative gateway corresponding to the service server may be selected to forward the service request for the client to access the service, so as to avoid processing by the degraded alternative gateway, thereby improving the processing efficiency of the service request and improving the performance of the SDP architecture.

Each preset gateway may correspond to all the service servers, or may also correspond to a part of all the service servers.

In the embodiment of the present invention, the controller may determine the target gateway from the alternative gateways in the following manners.

In one implementation, the controller may determine, based on the first access delay, a target gateway that meets a preset condition from among the candidate gateways. For example, the controller may determine the candidate gateway with the smallest first access latency as the target gateway. Alternatively, the controller may determine alternative gateways (which may be referred to as first preferred gateways) whose first access delay is smaller than a preset threshold, and further randomly determine one alternative gateway from the first preferred gateways as the target gateway. When the client accesses the target service server through the target gateway, the access time delay between the client and the target gateway is small, so that the forwarding efficiency of the service request can be improved, and further, the performance of the SDP framework is improved.

In another implementation manner, the controller may determine, based on the second access delay, a target gateway that meets a preset condition from among the candidate gateways. For example, the controller may determine the candidate gateway with the smallest second access latency as the target gateway. Alternatively, the controller may determine alternative gateways (which may be referred to as second preferred gateways) whose second access delay is smaller than a preset threshold, and further randomly determine one alternative gateway from the second preferred gateways as the target gateway. When the client accesses the target service server through the target gateway, the access time delay between the target gateway and the target service server is shorter, so that the processing efficiency of the service request can be improved, and further, the performance of the SDP framework is improved.

In another implementation manner, the controller may determine, from the candidate gateways, a target gateway that meets a preset condition based on a sum of the first access delay and the second access delay. For example, the controller may determine an alternative gateway (which may be referred to as a third preferred gateway) in which a sum of the second access delays of the first access delays is smaller than a preset threshold, and further randomly determine one alternative gateway from the third preferred gateway as the target gateway. When the client accesses the target service server through the target gateway, the access time delay is short, so that the processing efficiency of the service request can be improved, and further, the performance of the SDP framework is improved.

In another implementation, referring to fig. 3, on the basis of fig. 2, step S202 specifically includes:

s2021: and calculating the sum of the current first access time delay between the client and the alternative gateway and the current second access time delay between the alternative gateway and the target service server aiming at each alternative gateway corresponding to the target service server in each preset gateway.

S2022: and determining the alternative gateway with the minimum corresponding sum value as the target gateway.

Based on the processing, when the client accesses the target service server through the target gateway, the forwarding efficiency of the service request can be further improved, and the performance of the SDP framework is improved.

In step S203, in an implementation manner, the service request may carry a server identifier of the target service server, and correspondingly, the target gateway may determine to forward the service request to the target service server according to the server identifier. For example, the server identifier of the service server may be a port corresponding to the service server.

In addition, after forwarding the service request to the target service server, the target gateway may also receive a service response for the service request sent by the target service server, and forward the service response to the client.

In one embodiment, the client in the embodiment of the present invention may be client software of an SDP installed in the terminal device. The client can send a registration request carrying an account and a password to the controller, and correspondingly, the controller can register the client, record the account and the password of the client, and determine the access right of the client, namely, determine the service server with the access right of the client.

In one implementation, when a user logs in a client, the client may send an authentication request carrying an account and a password input by the user to a controller, and the controller may authenticate the received account and password based on the account and password recorded locally. If the authentication is passed, the controller can determine the access right of the client and notify the client. Further, the client may display the accessible service navigation page.

In one embodiment, the controller may also dynamically adjust the access rights of the client. For example, the controller may detect the security level of the client in real time. When the security level of the client is detected to be lower, the controller can modify the access authority of the client, so that the client does not have access to the service server corresponding to the important service. When the security level of the client is detected to be higher, the controller can modify the access authority of the client, so that the client can access more service servers corresponding to important services.

In one embodiment, the controller may also register the default gateway when the default gateway is deployed. After receiving the registration request sent by each preset gateway, the controller records the corresponding relationship between the network address of the preset gateway and the domain name of the corresponding service server. Subsequently, when the preset gateway is on-line again, the controller can also authenticate the preset gateway.

In an embodiment, referring to fig. 4, on the basis of fig. 2, before step S203, the method may further include:

s204: and acquiring a target domain name of a target service server carried in the domain name resolution request.

S205: and acquiring the network address of the target gateway from the network address of each alternative gateway corresponding to the target domain name according to a first corresponding relation between the preset domain name of the service server and the network address of the gateway.

In one implementation, the controller may record a correspondence between the domain name of each service server and the network address of each candidate gateway corresponding to the service server (i.e., the first correspondence in the embodiment of the present invention). The controller may determine, according to the first correspondence, a network address of an alternative gateway corresponding to the target service server, and may further acquire, from the determined network addresses of the alternative gateways, a network address of the target gateway.

For example, the domain name of the service server yi is yi.test.com, and the alternative gateway corresponding to the service server includes: alternative gateway g1, alternative gateway g 2. Com, the network address of each alternative gateway corresponding to the domain name yi.test.com recorded by the controller is: addr1, addr2, addr3, … … addrn. The current access delay between the client end devi and the alternative gateway gj is Cost _ dev _ gj, and the current access delay between the alternative gateway gj and the service server yi is Cost _ gj _ yi.

After the controller receives a domain name resolution request for a service server yi sent by a client, the controller calculates an access delay Cost _ dev _ gj _ yi for the client devi to access the service server yi through an alternative gateway gj, and the calculation is as follows:

Cost_devi_gj_yi＝Cost_devi_gj+Cost_gj_yi

and sequentially taking the value of j from 1 to n, and determining that when the value of j is k, the access delay Cost _ devi _ gk _ yi of the client terminal devi accessing the service server yi through the alternative gateway gk has the minimum value, namely Cost _ devi _ gk _ yi equals to min (Cost _ devi _ gj _ yi).

Then, the domain name resolution result of the controller for the service server yi is the network address addrk corresponding to the alternative gateway gk. That is, the controller may determine the alternative gateway gk as the target gateway.

In one embodiment, referring to fig. 5, on the basis of fig. 2, before step S202, the method may further include:

s206: and receiving the current first access delay between the client and each alternative gateway sent by the client.

S207: and receiving the current second access delay between the alternative gateway and the target service server sent by each alternative gateway.

Wherein, the current first access delay between the client and each alternative gateway is: the client is calculated based on the time of sending the first detection request to the alternative gateway and the time of receiving the first detection response sent by the alternative gateway, and the time is sent to the controller. The current second access delay between the alternative gateway and the target service server is: the alternative gateway is calculated based on the time of sending the second detection request to the target service server and the time of receiving the second detection response sent by the target service server, and is sent to the controller.

In the embodiment of the invention, the client can detect the access time delay between the client and each preset gateway and send the access time delay to the controller. Each preset gateway can detect the access time delay between the preset gateway and each corresponding service server and send the access time delay to the controller.

Further, the controller may obtain an access delay between the client and each of the predetermined gateways and an access delay between each of the predetermined gateways and each of the corresponding service servers.

The manner in which the client calculates the first access latency may refer to the detailed description of the method embodiment of the client below; the manner in which the alternative gateway calculates the second access delay may be referred to as detailed below with respect to the target gateway calculating the second access delay.

In one embodiment, the method may further comprise:

and issuing authority information which represents the access authority of the client aiming at each service server to each alternative gateway so that the target gateway sends the service request to the target service server under the condition of judging that the client has the access authority of the target service server when receiving the service request.

In one implementation, for each client, the controller may generate authority information of the client, where the authority information may be preset by a technician or determined by the controller according to a security level of the client. The controller may issue the authority information of the client to each preset gateway. Correspondingly, when a certain alternative gateway receives a service request sent by a client, whether the client has the authority to access the target service server can be judged according to the authority information of the client. If yes, the alternative gateway can send the service request to a target service server; if not, the alternative gateway may discard the service request, or may send a user alert to the client. The user prompt indicates that the client does not currently have access rights to the target service server.

In one embodiment, the method may further comprise:

and when the target gateway is detected to be abnormal, sending an abnormal notification to the client so that the client deletes the network address of the target gateway from the corresponding relation between the network address of the gateway and the domain name of the service server to update the second corresponding relation.

In the embodiment of the present invention, the controller may determine whether the target gateway is abnormal according to the first access delay and/or the second access delay. For example, when it is determined that the target gateway has a larger access delay according to the first access delay and/or the second access delay, it may be determined that the target gateway is abnormal.

In addition, each preset gateway may also periodically send a heartbeat message to the controller, and accordingly, the controller may determine whether the preset gateway is abnormal based on the heartbeat message sent by the preset gateway. For example, if the heartbeat message sent by the preset gateway is not received again when the preset time is reached after the heartbeat message sent by the preset gateway is received last time, the controller may determine that the preset gateway is abnormal. The preset duration is the period of sending the heartbeat message by the preset gateway.

Based on the same inventive concept, the invention provides a service request processing method, which can be applied to a client, and the client can be the client 101 in the system. Referring to fig. 6, the method may include the steps of:

s601: sending a domain name resolution request aiming at a target service server to a controller, so that the controller determines a target gateway meeting preset conditions from various alternative gateways according to the current first access time delay between the client and various alternative gateways corresponding to the target service server in various preset gateways and/or the current second access time delay between each alternative gateway and the target service server, and sending a network address of the target gateway to the client.

S602: and receiving the network address of the target gateway sent by the controller.

S603: and sending a first service request aiming at the target service server to the target gateway based on the network address of the target gateway, so that the target gateway sends the first service request to the target service server, and the target service server responds to the first service request.

In the method of the embodiment of the present invention, one service server may correspond to a plurality of candidate gateways in the preset gateways, and the controller may determine a target gateway satisfying a preset condition from the plurality of candidate gateways based on an access delay between the client and the candidate gateways and/or an access delay between the candidate gateways and the service server. That is to say, the controller may determine the target gateway based on the performance of the alternative gateways, and if the performance of a certain alternative gateway is degraded, may select another alternative gateway as the target gateway to forward the service request, so as to avoid processing by the degraded alternative gateway, and further, may improve the processing efficiency of the service request, and improve the performance of the SDP framework.

The client can send a registration request carrying an account and a password to the controller, and correspondingly, the controller can register the client, record the account and the password of the client, and determine the access right of the client, namely, determine the service server with the access right of the client.

In one implementation, when a user logs in a client, the client may send an authentication request carrying an account and a password input by the user to a controller, and the controller may authenticate the received account and password based on the account and password recorded locally. If the authentication is passed, the controller can determine the access right of the client and notify the client. Further, the client may display the accessible service navigation page. The user can select the service server to be accessed according to the accessible service navigation page.

In one embodiment, referring to fig. 7, on the basis of fig. 6, before step S601, the method further includes:

s604: and sending a first detection request to each alternative gateway.

S606: and sending the current first access delay between the client and the alternative gateway to the controller.

In one implementation, the client may periodically send a first detection request to each alternative gateway to detect a first access delay between itself and the alternative gateway in real time.

In one implementation, the client may calculate a difference between a time of sending the first detection request and a time of receiving the first detection response as the first access delay between the client and the alternative gateway.

In one embodiment, referring to fig. 8, on the basis of fig. 6, after step S602, the method further includes:

s607: and recording a second corresponding relation between the network address of the target gateway and the target domain name of the target service server.

S608: and when the target service server needs to be accessed, acquiring the network address of the target gateway corresponding to the target domain name of the target service server in the second corresponding relation.

S609: and sending a second service request aiming at the target service server to the target gateway based on the network address of the target gateway.

In one implementation, when a client needs to access a target service server, the client may send a domain name resolution request for the target service server to a controller. The controller then sends the network address of the target gateway to the client, which can use the network address to send a service request to the target gateway.

Furthermore, the client may also locally record a correspondence between the network address of the target gateway and the target domain name of the target service server (i.e., the second correspondence in the embodiment of the present invention). When the client needs to access the target service server again, the client does not need to send a domain name resolution request for the target service server to the controller again, and can directly obtain the network address of the target gateway according to the locally recorded second corresponding relation and send the service request to the target gateway by using the network address.

The client directly accesses the target service server according to the locally recorded second corresponding relation without domain name resolution through the controller, so that the processing efficiency of the service request can be improved, and the performance of the SDP framework is improved.

Based on the same inventive concept, the invention provides a service request processing method, which can be applied to a target gateway, and the target gateway can be a target gateway in the system. Referring to fig. 9, the method may include the steps of:

s901: and receiving a service request aiming at the target service server sent by the client.

The service request is sent by the client based on the network address of the target gateway received from the controller; the network address of the target gateway is: when receiving a domain name resolution request aiming at a target service server sent by a client, a controller determines a network address of a gateway meeting preset conditions from all the alternative gateways according to a current first access time delay between the client and each alternative gateway corresponding to the target service server in all the preset gateways and/or a current second access time delay between each alternative gateway and the target service server.

S902: and sending the service request to the target service server so that the target service server responds to the service request.

In one embodiment, referring to fig. 10, on the basis of fig. 9, before step S901, the method further includes:

s903: and sending a second detection request to the target service server.

S904: and when a second detection response aiming at the second detection request sent by the target service server is received, calculating the current second access delay between the target gateway and the target service server based on the time of sending the second detection request and the time of receiving the second detection response.

S905: and sending the current second access delay between the target gateway and the target service server to the controller.

In one implementation, each alternative gateway may periodically send a second detection request to the target service server to detect a second access delay between itself and the target service server in real time.

In one implementation, the alternative gateway may calculate a difference between a time of sending the second detection request and a time of receiving the second detection response as the second access delay between the alternative gateway and the target service server.

In one embodiment, the method further comprises:

and receiving authority information which is sent by the controller and represents the access authority of the client aiming at the target service server.

The step S902 may include:

and under the condition that the client side is judged to have the access right of the target service server, sending a service request to the target service server so that the target service server responds to the service request.

In one implementation, a client may send a registration request carrying an account and a password to a controller, and accordingly, the controller may register the client, record the account and the password of the client, and determine an access right of the client, that is, determine a service server to which the client has the access right. The controller may issue the authority information of the client to each preset gateway. Correspondingly, when a certain alternative gateway receives a service request sent by a client, whether the client has the authority to access the target service server can be judged according to the authority information of the client. If yes, the alternative gateway can send the service request to a target service server; if not, the alternative gateway may discard the service request, or may send a user alert to the client. The user prompt indicates that the client does not currently have access rights to the target service server.

The controller periodically obtains the time delay (first access time delay) between the preset gateway and the service server from the preset gateway, obtains the time delay (second access time delay) between the client and each preset gateway from the client, and stores the time delay.

The client sends an authentication request to the controller, the controller authenticates the client, and after the authentication is passed, the controller sends an accessible service navigation page to the client, and the controller issues user information and the authority of the user to access the service server to each preset gateway.

After the authentication is passed, the client displays an accessible service navigation page, the user clicks an icon corresponding to the service server representing the service yi, and the service server of the service yi is accessed, and the specific process is as follows: the client sends a domain name resolution request of a service server aiming at the service yi to the controller; the controller analyzes the domain name of the service server of the service yi and sends the network address of the target gateway obtained by domain name analysis to the client; the client accesses the service server of the service yi through the network address.

The controller periodically monitors the running state of the preset gateway, and when detecting that a certain preset gateway is abnormal, the controller sends an abnormal notification to the client so that the client deletes the network address of the preset gateway from the corresponding relationship between the network address of the gateway and the domain name of the service server to update the second corresponding relationship. When the client accesses the service server of the service yi again, the domain name resolution request of the service server aiming at the service yi is sent to the controller again, and the normal operation of the service is ensured.
