It may comprise steps of:
S210: the first access request of the destination service that client provides target device is received.
The first network agreement that client uses is different from the second network protocol that target device uses.
The source address of first access request is the address of client, and destination address is the first network agreement of proxy gateway
Address.
In embodiments of the present invention, the address for following first network agreement can be set in proxy gateway in advance,
The address for following first network agreement of the proxy gateway can be a public network address, be also possible to a private address, only
The proxy gateway is connectable to by the address.
In practical applications, the demand that client may have the service provided target device to access, but because
The two network protocol is different, so client can not directly access to the service of target device.In this case, client
The address access target equipment for following first network agreement of proxy gateway can be used in end.
Proxy gateway can receive the first access request of the destination service that client provides target device.First visit
The source address for asking request is the address of client, and destination address is the address for following first network agreement of proxy gateway.

The address of agreement.
After target device receives the first access request, can invocation target service respond thereto, and to proxy gateway
Return to the first response message.The source address of first response message is the address of target device, and destination address is proxy gateway
The second network protocol address.
After proxy gateway receives the first response message, the operation of step S240 can be continued to execute.
S240: the destination address of the first access request is converted to the address of target device.
After proxy gateway receives the first response message, agreement and address conversion, tool can be carried out to the first response message
Body, the first response message can be converted into first network agreement by the second network protocol, by the source of the first response message
Location is converted to the address for following first network agreement of proxy gateway, and the destination address of the first response message is converted to client
Address.The first response message is transformed into the network of first network agreement in this way.
In practical applications, proxy gateway can save session information, in this way, leading to when receiving the first response message
Session information is crossed, can determine the first access request corresponding to the first response message.
It, can be by the first response message after conversion after proxy gateway carries out agreement and address conversion to the first response message
It is sent to client, to respond the first access request of client initiation.
Certainly, if the first network agreement that uses of client is identical as the second network protocol that target device uses,
The service that client can directly provide target device accesses, and target device directly can carry out response to the access.
Using method provided by the embodiment of the present invention, proxy gateway is in the clothes for receiving client and providing target device
When the access request of business, which is subjected to agreement and address conversion, is transformed into the network of the second network protocol, then
Access request after conversion is sent to target device, when receiving the response message of target device return, which is believed
Breath carries out corresponding agreement and address conversion, is transformed into the network of first network agreement, and the response message after conversion is sent out
Give client.The intercommunication for realizing the network of different network protocol, does not need to be modified the service of target device, Ji Kewei
Client provides respective service, improves the utilization rate of the network equipment.
In one embodiment of the invention, after step S210, before S220, this method can also include following step
It is rapid:
Determine that destination service whether there is；If so, thening follow the steps S220 and its following operation.
In practical applications, with business variation or other reasons, the service that target device provides can may also occur
Variation, for example, there is new service online, or the service having is offline etc..
So in embodiments of the present invention, proxy gateway is in the destination service for receiving client and providing target device
Access request when, can first determine that destination service whether there is.Determine whether the destination service of target device is in online
State.
If it is, continuing to execute the operation that step S220 carries out network protocol conversion process to the first access request, such as
Fruit is no, then can ignore first access request, or return to miscue information to client.In this way, can be quickly to
One access request makes a response, to reduce the waiting time of client.
In one embodiment of the invention, this method may also comprise the following steps::
It is serviced according to present on setting time interval detection target device；
Based on service present on target device, the service of itself agency is updated.
In embodiments of the present invention, proxy gateway can according to setting time interval to serviced present on target device into
Row detection can be updated the service of agency based on servicing present on target device.If it find that have new service,
Then can be with the active agency service, if it find that there is service offline, then the respective service of its agency is also offline.
In this way, whether proxy gateway when determining that destination service whether there is, can be deposited in the agency service according to itself
Determine that destination service whether there is in destination service, it is not necessary to search again into target device.Shorten the response time.
Certainly, proxy gateway can find and act on behalf of automatically for the service that target device provides, can also be by manual
Configuration mode is acted on behalf of.
For ease of understanding, by taking first network agreement is IPv6, the second network protocol is IPv4 as an example, again to the above process
It is illustrated, as shown in figure 3, including IPv4 client, IPv6 client, the proxy gateway of IPv4 equipment and IPv4 equipment,
In:
S31: the address IPv6 is preset on proxy gateway；
S32: proxy gateway finds the service enabled in IPv4 equipment automatically, and carries out service broker；
S33:IPv6 client sends IPv6 service request to IPv4 equipment, reaches proxy gateway；
S34: the request is transformed into IPv4 network by proxy gateway；
S35: the request after conversion is sent to IPv4 equipment by proxy gateway；
Response message is returned to proxy gateway by S36:IPv4 equipment；
S37: response message is transformed into IPv6 network by proxy gateway；
S38: the response message after conversion is sent to IPv6 client by proxy gateway；
S39:IPv4 client directly sends IPv4 request to IPv4 equipment, and IPv4 equipment is directly returned to IPv4 client
Corresponding response message.
In one embodiment of the invention, this method may also comprise the following steps::
Step 1: target device is received to the second access request of the server-side for using first network agreement, the second access
The source address of request is the address of target device, and destination address is the second network protocol mapping address of server-side.
In practical applications, it needs target device to can also be used as client according to business and accesses other server-sides, such as visit
Ask the server-side using first network agreement.
The the second network protocol mapping address for needing the server-side accessed can be configured in target device in advance.
When target device will access the server-side using first network agreement as client, can be sent out to proxy gateway
Corresponding second access request out, the source address of the second access request are the address of target device, and destination address is server-side
Second network protocol mapping address.
Proxy gateway can continue to execute the operation of step 2 when receiving the second access request.
Step 2: the second access request is converted into first network agreement by the second network protocol, and the second access is asked
The source address asked is converted to the address for following first network agreement of proxy gateway, and the destination address of the second access request is converted
For the address of server-side.
It can be pre-configured in proxy gateway and to follow first network agreement using the server-side of first network agreement
The mapping relations of address and the address for following the second network protocol.
After proxy gateway receives the second access request, the conversion of agreement and address can be carried out to the second access request,
Specifically, the second access request can be converted to first network agreement by the second network protocol, by the source of the second access request
Address conversion is the address for following first network agreement of proxy gateway, and the destination address of the second access request is converted to service
The address at end.The second access request is transformed into the network of first network agreement.The address of server-side is the server-side
The address for following first network agreement.
Step 3: the second access request after conversion is sent to server-side.
Step 4: receiving the second response message that server-side returns, and the source address of the second response message is the ground of server-side
Location, destination address are the address of the first network agreement of proxy gateway.
The second access request after conversion is sent to server-side, which can call respective service to second visit
It asks that request carries out response, returns to the second response message.The source address of second response message is the address of server-side, and destination address is
The address for following first network agreement of proxy gateway.After proxy gateway receives the second response message, step can be continued to execute
Rapid five operation.
Step 5: by the second response message by first network protocol conversion be the second network protocol, and by the second response believe
The source address of breath is converted to the address for following the second network protocol of proxy gateway, and the destination address of the second response message is converted
For the address of target device.
Step 6: the second response message after conversion is sent to target device.
After proxy gateway receives the second response message, the conversion of agreement and address can be carried out to the second response message,
By the second response message by first network protocol conversion be the second network protocol, the source address of the second response message is converted into generation
The destination address of second response message, is converted to the address of target device by the address for following the second network protocol for managing gateway.
The second response message is transformed into the network of the second network protocol.Then the second response message after conversion is sent to mesh
Marking device.Realize that target device access uses the purpose of the server-side of first network agreement.
For ease of understanding, by taking first network agreement is IPv6, the second network protocol is IPv4 as an example, again to the above process
It is illustrated, as shown in figure 4, including IPv4 server-side, IPv6 server-side, the proxy gateway of IPv4 equipment and IPv4 equipment,
In:
S41: presetting the address IPv6 and an address IPv4 on proxy gateway, and configuration of IP v6 service and
IPv4 services mapping relations；
S42: the IPv4 mapping address of server-side is configured in IPv4 equipment；
S43:IPv4 device request IPv6 service；
S44: the request is transformed into IPv6 network by proxy gateway；
S45: the request after conversion is sent to IPv6 server-side by proxy gateway；
Response message is returned to proxy gateway by S46:IPv6 server-side；
S47: response message is transformed into IPv4 network by proxy gateway；
S48: the response message after conversion is sent to IPv4 equipment by proxy gateway；
S49:IPv4 equipment directly sends IPv4 request to IPv4 server-side, and IPv4 server-side is directly returned to IPv4 equipment
Corresponding response message.
In one embodiment of the invention, this method may also comprise the following steps::
First step: the domain name mapping for the target device service domain name to be accessed that name server returns is received
As a result；
Second step: if the corresponding address of service domain name follows first network agreement, the of proxy gateway is used
The corresponding address of Address Proxy service domain name of two network protocols, updates DNS response, and return to DNS response to target device；
Third step: third access request of the target device to the server-side for using first network agreement, third are received
The source address of access request is the address of target device, and destination address is the address for following the second network protocol of proxy gateway；
Four steps: third access request is converted into first network agreement by the second network protocol, and third is accessed
The source address of request is converted to the address for following first network agreement of proxy gateway, and the destination address of third access request is turned
It is changed to the address of server-side；The address of server-side is the corresponding address for following first network agreement of service domain name；
5th step: the third access request after conversion is sent to server-side；
6th step: receiving the third response message that server-side returns, and the source address of third response message is server-side
Address, destination address be proxy gateway the address for following first network agreement；
7th step: by first network protocol conversion it is the second network protocol by third response message, and third is answered
The source address for answering information is converted to the address for following the second network protocol of proxy gateway, by the destination address of third response message
Be converted to the address of target device；
8th step: the third response message after conversion is sent to target device.
It is illustrated for ease of description, above-mentioned eight steps are combined.
In practical applications, the domain name for needing the server-side accessed, the server-side can be configured in target device in advance
It can also be able to be the server-side for using the second network protocol for using the server-side of first network agreement.
When target device uses the domain name access server-side of server-side as client, first to name server, i.e. DNS
Server sends the domain name mapping request for the service domain name to be accessed, and the domain name mapping result that dns server returns reaches agency
Gateway.
After proxy gateway receives the domain name mapping result of dns server return, if it is determined that service domain name is correspondingly
Location follows first network agreement, then using the Address Proxy for following the second network protocol of proxy gateway, the service domain name is corresponding
Address updates DNS response, and DNS response is returned to target device.Meanwhile proxy gateway can save corresponding address and reflect
Penetrate relationship.
In this case, target device knows that the server-side to be accessed is the server-side using first network agreement, needs
Proxy gateway proxy access can be issued to proxy gateway accordingly in third access request, the source address of third access request
For the address of target device, destination address is the address for following the second network protocol of proxy gateway.
Proxy gateway can carry out agreement to third access request and address turns when receiving third access request
It changes, i.e., is transformed into third access request in the network of first network agreement.Third access request after conversion is sent to clothes
Business end, the server-side can call respective service to carry out response to the third access request, return to third response message.Act on behalf of net
After pass receives third response message, the conversion of agreement and address can be carried out to third response message, by third response message
It is transformed into the network of the second network protocol.Then the third response message after conversion is sent to target device.Realize target
Equipment access uses the purpose of the server-side of first network agreement.
In a kind of specific embodiment of the invention, proxy gateway is in the domain name mapping for receiving dns server return
As a result after, if the corresponding address of service domain name follows the second network protocol, the domain name mapping that will can directly receive
As a result target device is returned to as DNS response, so that target device directly accesses to the corresponding server-side of service domain name.
For ease of understanding, by taking first network agreement is IPv6, the second network protocol is IPv4 as an example, again to the above process
Be illustrated, as shown in figure 5, include dns server, IPv4 server-side, IPv6 server-side, IPv4 equipment proxy gateway and
IPv4 equipment, in which:
S51: the address IPv6 and an address IPv4 are preset on proxy gateway, and configures service domain name；
S52: the configuration service domain name in IPv4 equipment；
S53:IPv4 equipment sends domain name analysis request to dns server；
The parsing response that S54:DNS server returns reaches proxy gateway, and proxy gateway determines that it is the address IPv6, then makes
With IPv4 Address Proxy, and DNS response is returned into IPv4 equipment；
Service request is transformed into IPv6 network by S55:IPv4 device request IPv6 service, proxy gateway, and will be after conversion
Service request be sent to IPv6 server-side；
Response message is returned to proxy gateway by S56:IPv6 server-side；
S57: response message is transformed into IPv4 network by proxy gateway；
S58: the response message after conversion is sent to IPv4 equipment by proxy gateway；
The parsing response that S59:DNS server returns reaches proxy gateway, and proxy gateway determines that it is the address IPv4, then directly
Connect put it is logical, make its reach IPv4 equipment；IPv4 equipment directly to IPv4 server-side send IPv4 request, IPv4 server-side directly to
IPv4 equipment returns to corresponding response message.
It should be noted that above-mentioned some examples are all with first network agreement is IPv6, the second network protocol is
The explanation carried out for IPv4 still still fits the scene that first network agreement is IPv4, the second network protocol is IPv6
With repeating no more.
