Specific embodiment
Inventor has found that the gateway in the networks such as home network, enterprise network, in the network
Server in gateway is hung under either when providing service for user equipment, is usually provided pair for each service
The a port answered.Such as the WEB page service that gateway provides, 80 ports, the application that gateway provides can be used
17909 ports can be used in procedure service.In this way, when what gateway received user equipment transmission is directed to the port
When service access request, so that it may distinguish which kind of service user equipment to be requested access to according to the port, then can incite somebody to action
The service is supplied to user equipment.
But in some scenes, multiple and different services that user equipment is requested access to, may be required using
Identical port.At this moment, if there is at least two services while using identical port, asking for port collision may be generated
It is which kind of to be requested service that topic, specially gateway can not go out user equipment according to port identification, to cause partial service
The problem of can not accessing.For example, gateway is providing WEB (World Wide Web, global wide area network) page management function
When, need using 80 ports, and under hang over server in gateway when providing the website WEB, may be also required to using 80
Port.When user equipment, which is directed to 80 ports, initiates the request of access service, gateway can not determine that user equipment is to ask
The WEB page service for asking access gateway to provide still requests access to down and hangs over the WEB net that the server of gateway provides
The service of standing can only access the WEB page service of gateway offer so as to will lead to user equipment, and hang over net under
The WEB website service that the server of equipment provides is closed, user equipment can not access.
Based on this, the embodiment of the present application provides a kind of method of access service, so that gateway, which can be distinguished, to be made
It is avoided so that different services can share identical port in different clothes with the access request of the different services of same port
The problem of partial service can not access in the case where make suring with identical port.Specifically, user equipment can be sent out to gateway
Access request message is sent, it can basis after gateway receives the access request message to request access to the service needed for it
The characteristic carried in the access request message identifies the corresponding service of access request message, namely identifies user
Which kind of service is device request access, and then, which is sent to the processing module of the service by gateway, so as to
Corresponding service is provided in the processing module for user equipment.It follows that gateway is determining user equipment requests access
It is not to be distinguished according to port when which kind of service, but the spy in the access request message according to transmitted by user equipment
Sign data distinguish.In this way, even if a variety of services have shared identical port, gateway can also be sent out according to user equipment
The access request message sent, determines which kind of service is user equipment requests access, identical so as to avoid using in different services
The problem of partial service can not access in the case where port.
Still it is illustrated by taking 80 ports as an example, the WEB page service that gateway provides is needed using 80 ports, and under
Hang over the website WEB that the server in the gateway provides, it is also desirable to use 80 ports.User equipment is requesting access to WEB
When website, the access request message that the access website WEB that be directed to 80 ports is sent to gateway is understood, gateway is according to this
The characteristic that access request message carries, identifies that user equipment is the website WEB to be accessed, rather than accesses WEB page, then
The access request message can be sent to and provide the processing module of the website WEB by gateway, so that the processing module is to use
The service of the family equipment offer website WEB.In this way, hanging over gateway under even if gateway provides the service of WEB webpage
Server provides the service of the website WEB, has used identical 80 port, gateway can also distinguish user equipment requests
Which kind of service accessed.
A kind of method of access service provided by the embodiments of the present application, can be applied in network system as shown in Figure 1,
By taking application scenarios shown in FIG. 1 as an example, in the application scenarios, gateway 105 can be with multiple user equipment (user equipmenies
101, user equipment 102, user equipment 103, user equipment 104 etc.) data communication is carried out, when user equipment 101 needs to access
When the service that gateway 105 provides, which can send access request message to gateway 105, with request
The corresponding service of access；Then, gateway 105 can receive user equipment 101 transmission access request message, and according to
The characteristic carried in the access request message identifies the corresponding service of access request message, as destination service,
Under normal conditions, each access request message can correspond to a destination service；After determining destination service, gateway
105 can be sent to the access request message processing module of corresponding destination service, in order to the place of destination service
Reason module can provide corresponding service for user equipment 101.
It is understood that above-mentioned scene is only a Sample Scenario provided by the embodiments of the present application, the embodiment of the present application
It is not limited to this scene.
In order to make the above objects, features, and advantages of the present application more apparent, below in conjunction with attached drawing to this Shen
Please the various non-limiting implementations in embodiment illustrate.Obviously, described embodiment is the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
Referring to Fig.2, Fig. 2 shows the method flow schematic diagram of access service a kind of in the embodiment of the present application, this method tool
Body may include:
S201: gateway receives access request message.
In a kind of illustrative specific implementation, when user equipment to gateway either under hang over gateway
On server when requesting access to service, the access request message for accessing the service can be generated in user equipment, and sets to gateway
Preparation gives the access request message, with request gateway either under hang over server in gateway corresponding clothes be provided
Business, so that gateway receiving device can receive the access request message.
Wherein, the service that user equipment is requested access to, can be and provided by gateway, be also possible to hang over net by down
The server closed in equipment provides.For example, gateway can provide WEB page service to user equipment, or set to user
It is standby that specific application program service is provided；For another example, the server in gateway is hung under can provide WEB to user equipment
Website service, or transmitted by SSL (Secure Sockets Layer, Secure Socket Layer) to user equipment and service is provided
Deng.The server of gateway is hung under it is noted that, can be identical as public network IP used in gateway, the clothes
Business device belongs in the network environment that gateway is covered.
Difference based on the service that user equipment is requested access to, user equipment can send different access request reports
Text.For example, when user equipment requests access WEB page or when the website WEB, access request message that user equipment is sent can be with
It is HTTP (Hypertext Transfer Protocol, the hypertext transfer protocol) request message for being directed to the service；When with
When the service for the application program that family device request gateway provides, the access request message that user equipment is sent, which can be, to be directed to
In the request message of the application program；When the service that user equipment requests access is provided by SSL transmission, user equipment is sent
Access request message can be the SSL HELLO message for being directed to the service.
It should be noted that TCP (Transmission Control can be followed between user equipment and gateway
Protocol, transmission control protocol) agreement or UDP (User Datagram Protocol, User Datagram Protocol) agreement into
Row data communication.If following Transmission Control Protocol between user equipment and gateway carries out data communication, user equipment is to gateway
Before equipment sends access request message, it is also necessary to establish TCP connection between gateway；If user equipment and gateway it
Between follow udp protocol carry out data communication, then access request message directly can be sent to gateway by user equipment, to ask
Ask the corresponding service of access.
S202: the characteristic that gateway is carried according to access request message identifies that the access request message is corresponding
Service, and using the service as destination service.
In the present embodiment, the characteristic that access request message carries can be used as the clothes that user equipment is requested access to
The mark of business.In some instances, when the host field in the HTTP request message that characteristic is located at user equipment transmission,
If this feature data are the IP address of the gateway, it can identify what user equipment requests access gateway provided
WEB page service can identify user and set if this feature data hang over the domain name of the server in gateway under being
The standby WEB website service that server offer is provided；Characteristic is also possible to the mark of the application program, identifies use
Family device request accesses the service for the application program that gateway provides；Characteristic may be located in SSL HELLO message
SNI field, pass through SSL transmission offer to identify and hang over server in gateway under user equipment requests access
Service etc..
Then, gateway can be known after receiving access request message according to the characteristic in access request message
Not Chu user equipment requests which kind of service accessed, and the service is determined as destination service.It follows that gateway is being distinguished
When which kind of service is user equipment requests access, it can not be distinguished according to port, but according to transmitted by user equipment
Characteristic in access request message distinguishes, in this way, even if multiple services have shared identical port, gateway
Also the service that user equipment is requested access to can be determined from multiple services, so as to solve in the prior art, when more
A service shares an identical port and causes gateway to cannot be distinguished user equipment requests and access asking for which kind of service
Topic.
S203: gateway sends access request message to the processing module of destination service.
Under normal conditions, each service is provided by its corresponding processing module.Gateway is determining destination service
Later, the access request message which sends can be sent to the processing module of the destination service, in order to handle
Module responds the access request message, provides corresponding service for user equipment.
In some possible embodiments, if destination service is the service that gateway provides, the destination service
Processing module, can be deployed in the gateway, and if the server that destination service is hung under being in gateway mentions
The service of confession, then the processing module of destination service can dispose on that server, at this point, gateway as user equipment with
Access request message is transmitted to down the server hung in the gateway by the agency of server.
In the present embodiment, gateway, can be according to the visit after the access request message for receiving user equipment transmission
It asks characteristic entrained by request message, identifies which kind of service is user equipment requests access, then, gateway is by the visit
It asks that request is sent to corresponding processing module, in order to which the processing module is based on the access request message, is provided for user equipment
Corresponding service.As it can be seen that gateway determine user equipment requests access which kind of service when, be not according to port carry out area
Point, but distinguished according to the characteristic in access request message.In this way, even if gateway or under hang over gateway and set
A variety of services that standby upper server provides have shared identical port, and gateway can also be according to access request message, really
The user equipment service to be requested access to is made, so that different services can share identical port, is avoided not
The problem of partial service can not access in the case where using identical port with service.
The technical solution of the embodiment of the present application in order to facilitate understanding below says several illustrative application scenarios
It is bright.A kind of flow diagram of the scene embodiment of the method for access service in the embodiment of the present application is shown refering to Fig. 3, Fig. 3.
In this scenario, user equipment requests access WEB page, and provide service by gateway for the user equipment.This method tool
Body may include:
S301: user equipment sends the first HTTP request message for requesting access to WEB page to gateway, this first
HTTP request message is used to request to provide the service of WEB page to gateway.
In a kind of illustrative specific embodiment, if user equipment needs to access the WEB page of gateway offer
When, user equipment can pre-establish TCP connection with gateway, and after the completion of determining that TCP connection is established, user equipment can be with
The the first HTTP request message for being directed to the WEB page is sent, to gateway to request access to WEB pages of gateway offer
Face.
For example, terminal can root if enterprise staff needs the login page by terminal access enterprises system
According to the operation of the employee, the first HTTP request message of access login page is generated, and is establishing TCP connection with gateway
Afterwards, which is sent to gateway, accesses the enterprises in order to which gateway provides the terminal with
The service of the login page of system.
S302: gateway receives the first HTTP request message.
S303: gateway identifies that user sets according to the value of the host field of the heading of the first HTTP request message
The standby WEB page for requesting access to gateway, wherein the value of the host field is specially the IP address of gateway.
In the present embodiment, host field in the heading of the first HTTP request message can be used as user equipment requests
The mark of the service of access.Specifically, gateway can parse the host field in the first HTTP request message, really
The value of the fixed host field is the IP address of the gateway, it is determined that the service that user equipment is requested access to is gateway
The WEB page of offer.Wherein, the IP address for the WEB page that the IP address, as user equipment are requested access to.
As an example it is assumed that the service that gateway provides WEB page uses 80 ports, under hang over the clothes of the gateway
The WEB website service that business device provides also uses 80 port, when the WEB page clothes that user equipment requests access gateway provides
When business, user equipment can send the first HTTP request message for being directed to the WEB page service, gateway to gateway
80 ports can be monitored, and after receiving the first HTTP request message, to host in the first HTTP request message
The value of field is parsed, if it is determined that the value of the host field is the IP address of gateway, then can determine that user sets
Standby request access to is WEB page service that gateway provides, rather than the WEB website service that the server provides.
S304: gateway sends the first HTTP request message to the processing module for providing WEB page service, wherein should
Processing module is deployed in the gateway.
Gateway, can be according to user equipment requests after the service for determining user equipment requests access WEB page
The corresponding relationship of service and service processing module determines processing module corresponding with access WEB page service, it is then possible to
First HTTP request message is sent to the processing module, in order to which the processing module provides WEB page for user equipment.It needs
Illustrate, which is deployed in the gateway, belongs to the function comprising modules of gateway.
In the present embodiment, gateway is after the first HTTP request message for receiving user equipment transmission, according to first
The IP address that host field in HTTP request message is characterized, WEB pages for identifying user equipment requests access gateway
Face, and then the first HTTP request message is sent to corresponding processing module, in order to which corresponding processing module provides WEB pages
Face service.In the process, gateway is not to distinguish user equipment according to port to be accessed which kind of service, but root
The host field in the first HTTP request message sent according to user equipment, determines that user equipment needs to access WEB page, because
This, though in service provided by gateway, there are other services share with the WEB page service that gateway provides it is identical
Port, the WEB page service that gateway can also distinguish gateway offer is that user equipment is requested access to, thus
Avoid the problem of different services cause partial service that can not access using identical port.
In addition, there is also another exemplary scenes for the embodiment of the present application.The embodiment of the present application is shown refering to Fig. 4, Fig. 4
The flow diagram of the scene embodiment of the method for middle another access service.Unlike scene embodiment described in Fig. 3,
In the present embodiment, gateway is to identify user equipment requests according to the domain name of the server carried in HTTP access request
The WEB website service that the service of access hangs over gateway server under being provides.Specifically, this method may include:
S401: user equipment initiates to establish the request of TCP connection to gateway.
S402: gateway receives and responds TCP connection request, establishes TCP connection with user equipment.
Under normal conditions, when user equipment need with gateway carry out data communication when, user equipment firstly the need of to
Gateway is initiated to establish the request of TCP connection, establishes TCP connection with gateway with request, and between gateway
After establishing TCP connection, user equipment and gateway carry out normal data communication.
S403: user equipment sends the second HTTP request message for requesting access to the website WEB to gateway, this second
The server request that HTTP request message is used to hang over downwards the gateway provides the service of the website WEB.
S404: gateway receives the second HTTP request message.
S405: gateway identifies that user sets according to the value of the host field of the heading of the second HTTP request message
Standby request access to down hangs over the website WEB that the server of gateway provides, wherein the value of the host field is specially the service
The domain name of device.
In the present embodiment, host field in the heading of the second HTTP request message can be used as user equipment requests
The mark of the service of access.Specifically, gateway can parse the host field in the second HTTP request message, really
The value of the fixed host field hangs over the domain name of the server in the gateway under being, then can determine user equipment to which
Server request offer service, and, determine user equipment it is requested be the server provide WEB website service.
The WEB website service that the server offer of gateway is hung under as an example it is assumed that uses 80 port, the net
The service for closing equipment offer WEB page also uses 80 ports, when user equipment requests access the website the WEB clothes of server offer
When business, user equipment can send the second HTTP request message for being directed to the WEB website service, gateway to gateway
80 ports can be monitored, and after receiving the second HTTP request message, to host in the second HTTP request message
The value of field is parsed, if it is determined that the value of the host field is the domain name of the server, then can determine user equipment
What is requested access to is the WEB website service that the server provides, rather than the WEB web service that gateway provides.
S406: the second HTTP request message is sent to and is provided in the server of WEB website service by gateway, the clothes
Business device hangs over the server in gateway under being.
