Below in conjunction with Figure of description, the embodiment of the present invention is described in detail.
Fig. 1 is the connection switching method according to one embodiment of the invention, can comprise step:
S101: client and service server are set up first and be connected, carries out data interaction by this first connection with service server.
S102: client determines the first acceleration server that will be switched to.
S103: client connects by first handover request sending the server identification information carrying this first acceleration server to service server.
S104: client is accelerated server foundation by first and is connected with second of this service server.
S105: client sends the data to the first acceleration server, the first acceleration server is made to add in data by this first server identification information accelerating server, and send to service server by the second connection, carry out data interaction by the second connection with client to make service server.
From the foregoing, according to this embodiment, client is when connecting by first and service server carries out exchanges data, the handover request of the server identification information carrying the acceleration server (the acceleration server that will be switched to is the first acceleration server) that will be switched to can be sent to service server, and be connected with second of service server by the foundation of this acceleration server, send the data to this acceleration server, the server identification information of self adds to after in data and sends to service server by this acceleration server, service server then connects by second and client carries out data interaction, therefore, client is without the need to disconnecting the connection with service server, can realize carrying out switching in the process of data interaction being connected with service server, effectively can improve the efficiency of data interaction between client and service server.
According to one embodiment of the present of invention, step S103 as shown in Figure 1 and the execution sequence of S104 are in no particular order.Client is when being connected with second of service server by the first acceleration server foundation, server can be accelerated to first and send connection establishment request, first accelerates server then when receiving the connection establishment request that client sends, set up for client and be connected with second of service server, also namely, second described in the embodiment of the present invention connects and comprises client and accelerate the connection of server and accelerate the connection of server and service server.
It is acceleration server in order to this client of informing business server will be switched to that client sends the object of handover request to service server.Certainly, after service server receives this handover request, can connect by first equally and return handoff response to client, to inform that this service server of client receives handover request.
Accelerate server the server identification information of self to be added in the data that client sends and send to the object of service server to be again: which these data of informing business server accelerated server and sent by.
And service server is after receiving the data that service server sends, can judge that whether the server identification information carried in the data received is identical with the server identification information carried in handover request, if, then connect by second and carry out data interaction with client, otherwise, refuse to connect by second to carry out data interaction with client.The server identification information carried in the data that service server judging the receives object whether identical with the server identification information carried in handover request be then: judge that the whether certain acceleration server of being informed by it of client have sent data to service server.Therefore, if the determination result is YES, then can determine that client sends data by its acceleration server of informing to service server, switch correct, thus service server by this acceleration server to client return data, namely, connect by second and carry out data interaction with client, if judged result is no, then determine that client does not send data by its acceleration server of informing, switching makes mistakes, thus service server is refused by this acceleration server to client return data, that is, refuse to connect by second to carry out data interaction with client.
According to one embodiment of the present of invention, establish direct-connected first with service server in client to be connected, and when carrying out data interaction by this first connection, client, first is accelerated to connect by mutual realization the concrete grammar switched between server and service server three and can as shown in Figure 2, be comprised the following steps:
S201: client determines the first acceleration server that will be switched to.
S202: client connects by first handover request sending the server identification information carrying this first acceleration server to service server.
S203: client is accelerated server foundation by first and is connected with second of this service server.
S204: client sends the data to the first acceleration server.
S205: the first accelerates server adds to this first server identification information accelerating server in data, and sends to service server by the second connection.
S206: when the server identification information that service server carries in the data determining to receive is identical with the server identification information carried in handover request, connects by second and carries out data interaction with client.
Such as, user when being played games by network, the client of this user can first set up with game server (namely, service server) direct-connected relation, this direct-connected relation is the first connection, carries out data interaction by this first connection with game server, and keeps this first connection not disconnect.
When client is determined to be switched to by accelerating server 1 and being connected to game server, then connect by first, carry the handover request of the server identification information of this acceleration server 1 to game server, and be connected with second of game server by accelerating server 1 foundation simultaneously.Also can to game server handover request, and after receiving the handoff response that game server returns, then set up be connected with second of game server by accelerating server 1.This second connection comprises client and accelerates the connection of server 1 and accelerate the connection of server 1 and game server.
Accelerating server 1 is after client and game server establish the second connection, client then can send to the data of game server to send to and accelerate server 1, accelerate server 1 server identification information of self is added in these data, and send to game server.
Owing to have received the handover request of the server identification information carrying this acceleration server 1 before game server, therefore, after receiving and accelerating the data sent of server 1, can judge that whether the server identification information that carries in these data is the server identification information of this acceleration server 1 carried in handover request, if, the data that then game server can return to client send to accelerates server 1, by accelerating server 1, these data are returned to client, namely, connect by second and carry out data interaction with client, otherwise, refuse to connect by second to carry out data interaction with client.
As can be seen from upper example, due to client be when maintenance first connect do not disconnect, inform its acceleration server 1 that will be switched to of game server, and be connected with second of game server by the foundation of acceleration server 1, the most originally will connect by first sends to the data of game server to give game server by the second connection transmission, therefore, can without the need to disconnecting the connection with game server, also be, user can without the need to rolling off the production line, can realize switching in reciprocal process connecting, improve the efficiency of data interaction.
According to one embodiment of the present of invention, client is when determine to be switched to first accelerates server, the first time of delay that client can connect first, and monitored by the second time of delay that each acceleration server is connected to service server, when monitoring existence and being less than second time of delay of this first time of delay, be defined as by the acceleration server corresponding the second minimum time of delay being switched to first accelerates server.
Wherein, monitoring first time of delay that client can be real-time and the second time of delay, also can according to setting cycle, periodically the first time of delay of monitoring and the second time of delay.Client is when the first time of delay that monitoring first connects, connect by first and send test data to service server, and record delivery time, when receiving by first the test response data that service server returns, record the time of reception, according to the time span of this delivery time to the time of reception, determined for the first time of delay.Similar, client is when monitoring is connected to the second time of delay of service server by certain acceleration server, also test data is sent by this acceleration server to service server, and record delivery time, when being received the test response data that service server returns by this acceleration server, record the time of reception, according to the time span of this delivery time to the time of reception, determined for the second time of delay.
Such as, its first time of delay be connected with first of service server of client control is 80ms, second time of delay being connected to service server by accelerating server 1 of monitoring is 97ms, the second time of delay being connected to service server by accelerating server 2 is 63ms, the second time of delay being connected to service server by accelerating server 3 is 75ms, then client determines that the second time of delay that there is acceleration server 2 and accelerate server 3 is less than this first time of delay, therefore, by the acceleration server corresponding the second minimum time of delay monitored, namely, the acceleration server 2 that 63ms is corresponding, be defined as being switched to first accelerates server.
According to one embodiment of the present of invention, in order to which acceleration server will be which client of informing business server will be switched to more accurately, when client connects transmission handover request by first, also the client identification information of this client self also can be carried in handover request and send to service server, also be, client connects by first, sends the handover request of carrying the server identification information of the first acceleration server and the client identification information of this client to service server.Like this, by the client identification information that carries in this handover request and server identification information, service server can know which which client will be switched to and accelerate server accurately.
Wherein, client identification information described in the embodiment of the present invention can comprise: medium education (MediaAccessControl, MAC) address, the combination of one or more logged in identify label (IDentity, ID), cookie that username and password is corresponding etc.Server identification information can comprise: accelerate the combination of one or more in the IP address of server, the title of acceleration server, the URL(uniform resource locator) (Uniform ResourceLocator, URL) of acceleration server etc.
Take client identification information as the login ID of client, server identification information is the URL of acceleration server is example, and the form carrying the handover request of client identification information and server identification information can be:
<qh>
ip:1.1.1.1|cdnsvr:jiasu1.com|khid:12345
</qh>
In the handover request of above-mentioned form, 1.1.1.1 is Internet protocol (InternetProtocol, the IP) address of client, and for identifying the source address of this handover request, 12345 is the login ID of client, and jiasu1.com is the URL accelerating server.By this handover request, service server can know that the client that IP address is 1.1.1.1, login ID is 12345 will be switched to the acceleration server that URL is jiasu1.com accurately.
Accordingly, client sends before data to service server accelerating server by first, also the client identification information of this client self to be sent to the first acceleration server, concrete, the client identification information of this client self when accelerating server transmission connection establishment request to first, can be carried in this connection establishment request and sending to the first acceleration server by client.When then the first acceleration server receives the data of client transmission, this first server identification information accelerating server self and this client identification information received can be added in the data received, and send to service server.
Be still IP address and the login ID of client with client identification information, server identification information is the URL of acceleration server is example, first accelerates server adds to the server identification information of self and the client identification information that receives after in the data that client sends, and the form of these data can be:
<cdnip>jiasu1.com</cdnip>
<khid>12345<khid>
<khsj>
// be the data that client is sent herein
<khsj>
</cdnsvr>
After the above-mentioned data that with the addition of server identification information jiasu1.com and client identification information 12345 are sent to service server, service server then can judge that whether the server identification information carried in the data received is identical with the server identification information carried in handover request, and judge that whether the client identification information carried in the data received is identical with the client identification information carried in handover request, if two judged results are and are, then determine that the acceleration server that the client sending handover request is informed by it have sent data to service server, thus carry out data interaction by the second connection with client, if at least one judged result is no, then determine that the acceleration server that the client sending handover request is not informed by it sends data to service server, refuse to connect by second to carry out data interaction with client.
According to one embodiment of the present of invention, when client carries out data interaction by the second connection with service server, save Internet resources if consider, then can disconnect client and be connected with first of service server.But consider first time of delay that will be connected by this first connection monitoring first, and follow-up also may also will connection from second switches back the first connection, therefore, this embodiment of the invention, when client carries out data interaction by the second connection with service server, still can keep client to be connected with first of service server.
More than carrying out in the process of data interaction for connecting by direct-connected first in client with service server, seamlessly switching to and accelerating server by certain and to be connected with service server and the method for being carried out data interaction by this acceleration server and service server.
The following describes and accelerate second of server in client by first and connect and carry out in the process of data interaction with service server, seamlessly switch to direct-connected first and connect the method for carrying out data interaction with service server.
According to one embodiment of the present of invention, because client is being carried out in the process of data interaction by the second connection (second connects by the first acceleration server foundation) with service server, still remain direct-connected with service server first to be connected, therefore, client is being carried out in the process of data interaction by the second connection with service server, when determining to be switched to the first connection and service server carries out data interaction, then directly can disconnect this second connection, and carry out data interaction by this first connection with service server.
Wherein, client can be less than in the first time of delay monitoring the first connection any one by accelerate server be connected to the second time of delay of service server time, determine from second connect be switched to the first connection.
When disconnection second connects, client can be accelerated server to first and send connection disconnection request.First acceleration server then disconnects being connected with second of client and service server of its foundation, client and service server is connected by first and carries out data interaction after receiving this connection disconnection request.
Wherein, this connection disconnects the identification information that the client identification information and first that can carry this client self in request accelerates server, and form can be as follows:
<cdnqh>
ip:1.1.1.1|cdnsvr:jiasu1.com|khid:12345
</cdnqh>
Wherein, 1.1.1.1 is the IP address of client, and disconnect the source address of request for identifying this connection, 12345 is the login ID of client, and jiasu1.com is the URL of the first acceleration server.After the connection receiving above-mentioned form disconnects and asking, first accelerates server can know that the client-requested that IP address is 1.1.1.1, login ID is 12345 disconnects the second connection.
Certainly, after the first acceleration server receives and connects the request of disconnection, also can forward this connection disconnection to service server and ask, service server is known, and this client will disconnect the second connection, connect carry out data interaction with service server by first.
The following describes and carry out in the process of data interaction by the second connection that first accelerates server with service server in client, seamlessly switch to the method for being carried out data interaction by the second acceleration server and service server, as shown in Figure 3, can comprise the following steps:
S301: client determine to be switched to by second accelerate server is connected with service server time, disconnection second connection.
S302: the first accelerates server disconnects being connected with second of client and service server of its foundation.
S303: client connects by first, resends the handover request of the server identification information carrying this second acceleration server to service server.
S304: client is accelerated server foundation by second and is connected with the 3rd of service server.
S305: client sends the data to the second acceleration server.
S306: the second accelerates server adds to the server identification information of self in the data received, and sends to service server by the 3rd connection.
