The embodiment of the invention provides an information processing method based on an FTP (file transfer protocol), which can be applied to an information processing system based on the FTP, wherein the information processing system comprises an FTP cluster, a client and a flow forwarder for enabling a server of the FTP cluster to be communicated with the client. The client and the server both support the FTP protocol, and before the data transmission connection between the client and the server is established, the client establishes a command interaction request with the server through the traffic forwarder. When the command interaction request is established, the client and one server in the FTP cluster already determine to establish a connection for 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 the specified 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 allocating address information to 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 a server or an identifier corresponding to each port of the server, 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 identify one server in the FTP cluster.
Step S102: and configuring identification information for the flow forwarder connected with the server, wherein the identification information comprises the association relationship between the server and the address information corresponding to the server.
Specifically, the identification information is used to enable the traffic forwarder to determine a data interaction channel negotiated between the client and the server during the command interaction request, so that after the traffic forwarder configures the identification information, the traffic forwarder can determine the unique server corresponding to the address information.
Step S103: when a flow repeater receives a data transmission request sent by a client, determining a server for receiving the data transmission request based on pre-configured identification information and the data transmission request; wherein the data transmission request includes at least determination information corresponding to the address information.
In some optional embodiments, the determination information may be directly address information, and after the traffic forwarder obtains the data transmission request, the traffic forwarder can determine, based on the address information and the identification information configured for the traffic forwarder in advance, a server that should receive the data transmission request, so as to avoid that the data transmission request is erroneously transmitted to another server, and data loss occurs. In some other embodiments, the determination information may also be information obtained by encrypting address information, in short, the determination information may be used to determine the address information, and then the traffic forwarder may determine the server by combining the address information and the identification information.
Through 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 appointed server through the flow forwarder without an additional monitoring means.
According to the invention, the address information uniquely corresponding to the server is distributed to each server in the FTP cluster, and the identification information is configured for the flow forwarder connected with the server, so that the flow forwarder can determine the server for receiving the data transmission request based on the pre-configured identification information and the data transmission request, the data transmission request can be accurately transmitted to the negotiated server, the difficulty in 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 includes: and when the address information is the port range, the port ranges corresponding to the servers in the FTP cluster are not overlapped.
Exemplarily, as shown in fig. 2, fig. 2 shows 4 servers in an FTP cluster, that is, a server No. 1, a server No. 2, a server No. 3, and a server No. 4, where the number of servers in the FTP cluster is merely an example, and it should be noted that the application does not specifically limit the number of servers in the FTP cluster. The port ranges corresponding to the 4 servers are all different, the port range corresponding to the server No. 1 is 2000-year-old, the port range corresponding to the server No. 2 is 2001-year-old 3000, the port range corresponding to the server No. 3 is 3001-year-old 4000, and the port range corresponding to the server No. 4 is 4001-year-old 5000.
And allocating port ranges for all servers in the FTP cluster, wherein the port ranges corresponding to all the servers are not overlapped, and configuring identification information corresponding to the port ranges for a traffic forwarder connected with the servers. When the traffic forwarder receives a data transmission request sent by the client, the traffic forwarder can determine a server which receives the data transmission request based on the pre-configured identification information and the data transmission request which contains the determination information corresponding to the port range. For example, if the data transfer request includes the determination information corresponding to the port 1001, it is determined that the server receiving the data transfer request is the server No. 1 in the FTP cluster.
Specifically, the forwarding port of the traffic forwarder is used for sending a data transmission request, a command interaction request and the like to the server.
In some embodiments, as shown in fig. 3, the information processing method further includes: and under the condition that the address information is the IP address corresponding to the server, allocating different IP addresses to each server pair in the FTP cluster.
Exemplarily, as shown in fig. 3, the IP addresses corresponding to the 4 servers shown in fig. 3 are all different, and the IP address corresponding to the server No. 1 is 10.1.1.2; the IP address corresponding to the server No. 2 is 10.1.1.3; the IP address corresponding to the server No. 3 is 10.1.1.4; server number 4 corresponds to an IP address of 10.1.1.5.
And allocating an IP address for each server in the FTP cluster, wherein the IP address corresponding to each server is unique, and configuring identification information corresponding to the IP address for a flow forwarder connected with the server. When the traffic forwarder receives the data transmission request sent by the client, the traffic forwarder can determine the server receiving the data transmission request based on the preset identification information and the data transmission request containing the determination information corresponding to the IP address. For example, if the data transfer request includes the specific information corresponding to the IP address 10.1.1.4, the server receiving the data transfer request is determined to be the server No. 3 in the FTP cluster.
In some embodiments, as shown in fig. 4, before the traffic forwarder receives the data transmission request transmitted by the client, the information processing method further includes steps S201 to S202.
Step S201: and acquiring a command interaction request which is sent by the client and used for establishing a command interaction channel with the server.
Step S202: forwarding the command interaction request to a server via a traffic forwarder.
Specifically, before establishing a data transmission channel between the client and the server, a command interaction channel between the client and the server is established. After the traffic forwarder receives the command interaction request sent by the client, determining a designated server in the FTP cluster to communicate with the client through the traffic forwarder.
In some embodiments, before the traffic forwarder receives the data transmission request transmitted by the client, the information processing method further includes step S301.
Step S301: under the condition that the server receives the command interaction request and is in an FTP passive mode, sending address information corresponding to the command interaction request to a client through the server; the address information is an address which can enable the server and the client to establish data transmission.
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 forwarder; step S303: and the traffic forwarder sends the address information to the client.
Specifically, the FTP passive mode may be understood as that the client connects to a port of a server in the FTP cluster to send a command, and the server negotiates with the client about a service port connected to the client, so as to send data through the port.
Specifically, the server sends the address information to the client under the command interaction channel to prepare for subsequent data transmission.
In some embodiments, the information processing method further includes: 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 containing 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 of a communication negotiated before the client.
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 the server via the traffic forwarder specifically includes:
the flow forwarder acquires the command interaction request and configures one server in the FTP cluster connected with the client for the client based on a preset algorithm;
