The embodiment of the application provides an information processing method based on an FTP protocol, which can be applied to an information processing system based on the FTP protocol, wherein the information processing system comprises an FTP cluster, a client and a flow transponder for enabling a server and the client of the FTP cluster to communicate. The client and the server both support the FTP protocol, and before establishing a data transmission connection between the client and the server, the client establishes a command interaction request with the server through the traffic forwarder. When a command interaction request is established, the client and one server in the FTP cluster have determined to establish a connection to perform subsequent data transmission, but when the traffic forwarder forwards the subsequent data transmission request, it is not clear that the data transmission request is forwarded to a designated server in the FTP cluster, so that there is a possibility of data loss, and for the above situation, as shown in fig. 1, the information processing method based on the FTP protocol according to the embodiment of the present application includes steps S101 to S103.
Step S101: and distributing address information for each server in the FTP cluster, wherein the address information is an address uniquely corresponding to the server.
It is understood that the address information may be configured as an identifier corresponding to the server one by one, or an identifier corresponding to each port of the server one by one, and more specifically, the address information may be at least one of the following: an IP address corresponding to the server, and a port range corresponding to the server.
Specifically, the address information has uniqueness, that is, each address information can uniquely determine one server in the FTP cluster.
Step S102: and configuring identification information for the traffic forwarder connected with the server, wherein the identification information comprises an association relation between the server and address information corresponding to the server.
Specifically, the identification information is used for enabling the traffic forwarder to determine a data interaction channel negotiated by the client and the server when the client and the server command interaction requests, so that the traffic forwarder can determine a unique server corresponding to the address information after configuring the identification information.
Step S103: when a traffic forwarder receives a data transmission request sent by a client, determining a server for receiving the data transmission request based on preconfigured identification information and the data transmission request; wherein the data transmission request includes at least determination information corresponding to the address information.
In some alternative embodiments, the determining information may be address information directly, and after the traffic forwarder obtains the data transmission request, the traffic forwarder may determine, based on the address information and the identification information configured for the traffic forwarder in advance, a server that should accept the data transmission request, so as to avoid situations such as data loss caused by the data transmission request being erroneously transmitted to other servers. In some other embodiments, the determination information may be information obtained by encrypting the address information, and in any case, the address information may be determined by the determination information, and the traffic forwarder may determine the server by combining the address information and the identification information.
By the information processing method based on the FTP protocol, the command interaction request and the data transmission request of the client can be sent to the same server, and the data transmission request can be forwarded to the designated server through the flow transponder without additional monitoring means.
The application distributes the address information uniquely corresponding to the server for each server in the FTP cluster, and configures the identification information for the traffic forwarder connected with the server, so that the traffic forwarder can determine the server receiving the data transmission request based on the preconfigured identification information and the data transmission request, the data transmission request can be accurately transmitted to the negotiated server, the difficulty of realizing the FTP cluster is effectively reduced, and the high-quality data transmission requirement can be met on the basis of low cost.
In some embodiments, the information processing method further comprises: if the address information is a port range, the port ranges corresponding to the servers in the FTP cluster do not overlap.
As shown in fig. 2, the number of servers in the FTP cluster, that is, the number 1 server, the number 2 server, the number 3 server, and the number 4 server, is shown in fig. 2, and the number of servers in the FTP cluster is merely an example, and it should be noted that the number of servers in the FTP cluster is not specifically limited by the present application. The port ranges corresponding to the 4 servers are all different, the port range corresponding to the No. 1 server is 1000-2000,2, the port range corresponding to the No. 2001-3000,3 server is 3001-4000,4, and the port range corresponding to the No. 4001-5000.
Port ranges are allocated to each server in the FTP cluster, the port ranges corresponding to the servers are not overlapped, and identification information corresponding to the port ranges is configured for traffic forwarders connected with the servers. When the traffic forwarder receives a data transmission request sent from the client, the traffic forwarder can determine a server that receives the data transmission request based on the preconfigured identification information and the data transmission request including determination information corresponding to the port range. For example, if the data transmission request includes the determination information corresponding to the port 1001, it is determined that the server that receives the data transmission request is server No. 1 in the FTP cluster.
Specifically, the forwarding port of the traffic forwarder is used to send a data transmission request, a command interaction request, etc. to the server.
In some embodiments, as shown in fig. 3, the information processing method further includes: and when the address information is the IP address corresponding to the server, allocating different IP addresses for each server pair in the FTP cluster.
As shown in fig. 3, the IP addresses corresponding to the 4 servers shown in fig. 3 are different, and the IP address corresponding to the server No. 1 is 10.1.1.2; the IP address corresponding to the No. 2 server is 10.1.1.3; the IP address corresponding to the server No. 3 is 10.1.1.4; the IP address corresponding to server No. 4 is 10.1.1.5.
And distributing IP addresses to all servers in the FTP cluster, wherein the IP addresses corresponding to the servers are unique, and configuring identification information corresponding to the IP addresses for traffic forwarders connected with the servers. When the traffic forwarder receives the data transmission request sent from the client, the traffic forwarder can determine the server receiving the data transmission request based on the preconfigured identification information and the data transmission request containing the determination information corresponding to the IP address. For example, if the data transmission request includes the determination information corresponding to the IP address 10.1.1.4, it is determined that the server that receives the data transmission request is server No. 3 in the FTP cluster.
In some embodiments, as shown in fig. 4, before the traffic forwarder receives the data transmission request sent by the client, the information processing method further includes steps S201 to S202.
Step S201: and acquiring a command interaction request sent by the client for establishing a command interaction channel with the server.
Step S202: the command interaction request is forwarded to a server via a traffic forwarder.
Specifically, a command interaction channel between the client and the server is established before a data transmission channel between the client and the server is established. After the traffic forwarder receives the command interaction request sent by the client, the traffic forwarder determines that the client is communicated with a designated server in the FTP cluster.
In some embodiments, the information processing method further includes step S301 before the traffic forwarder receives the data transmission request sent by the client.
Step S301: under the condition that the server receives the command interaction request and is in the FTP passive mode, address information corresponding to the command interaction request is sent to a client through the server; the address information is an address capable of enabling the server to establish data transmission with the client.
Specifically, as shown in fig. 4, step S301 may specifically include step S302 and step S303, step S302: the server sends the address information corresponding to the server to the flow transponder; step S303: the traffic forwarder then sends the address information to the client.
Specifically, the above-mentioned FTP passive mode may be understood as a port transmission command of a client to connect to a server in the FTP cluster, and the server will negotiate a service port to connect to the client to transmit data through the port.
Specifically, the server sends address information to the client under the command interaction channel to prepare for subsequent data transmission.
In some embodiments, the information processing method further comprises: generating the data transmission request containing the determination information based on the address information received by the client; wherein the determination information is used for determining a server that receives the data transmission request.
Specifically, after receiving the address information, the client generates a data transmission request including determination information before sending the data transmission request, so that the traffic forwarder receiving the data transmission request can determine, in combination with the determination information, a server to receive the data transmission request, that is, a server for which the client has previously negotiated communication.
In some embodiments, as shown in fig. 4, the information processing method further includes step S401, step S401: the client sends a data transmission request to the traffic forwarder.
In some embodiments, as shown in fig. 4, after determining the server that receives the data transmission request, the information processing method further includes step S501.
Step S501: forwarding the data transmission request to the determined server via the traffic forwarder; wherein the data transmission request comprises at least a data packet.
In some embodiments, step S501: the forwarding the command interaction request to a server via a traffic forwarder specifically includes:
the flow forwarder acquires the command interaction request and configures a server in the FTP cluster connected with the client based on a preset algorithm;
and after the server is configured, forwarding the command interaction request to the server.
Specifically, the preset algorithm may be at least one of a polling algorithm and a load balancing algorithm. The server can be reasonably distributed to the client through a preset algorithm.
