Abstract
According to an example, a file transfer protocol data transmission method applied in a stack system includes an FTP server master process receiving a file transfer request from an FTP client, for a file requested by the file transfer request, the FTP server master process judging whether the file and the FTP server master process are in a same chassis, when the file and the FTP server master process are not in the same chassis, the FTP server master process sends a file transfer notice to an FTP server slave process running on a chassis which is in the stack system and which the file is in.
Claims15
A file transfer protocol (FTP) data transmission method applied in a stack system, the method comprising:
- receiving, by an FTP server master process in the stack system, a file transfer request from an FTP client;
- and
- for a file requested by the file transfer request, judging, by the FTP server master process, whether the file and the FTP server master process are in a same chassis;
- if the file and the FTP server master process are not in the same chassis:
- sending, by the FTP server master process, a file transfer notice to an FTP server slave process running on a chassis which is in the stack system and which the file is in.
A file transfer protocol (FTP) data transmission method applied in a stack system, the method comprising:
- receiving, by an FTP server slave process in the stack system, a file transfer notice from an FTP server master process, wherein the file transfer notice instructs the FTP server slave process to take over download of a file which is requested by an FTP client and is in a chassis where the FTP server slave process runs;
- taking over, by the FTP server slave process execution of transmission of the file through a data link to transfer the file between the FTP server slave process and the FTP client after the FTP server slave process receives the file transfer notice.
A network device acting as a master device in a stack system, the network device comprising:
- a processor for executing a file transfer protocol (FTP) server master process stored in a memory, the FTP server master process comprising:
- a request receiving unit, a judgment unit, and a transfer notification unit;
- wherein:
- the request receiving unit is to receive a file transfer request from an FTP client;
- the judgment unit is to, for a file requested by the file transfer request, judge whether the file is in the network device;
- the transfer notification unit is to, when a judgment result of the judgment notification unit is no, send a file transfer notice to an FTP server slave process running on a chassis which is in the stack system and which has the file.
A network device acting as a slave device in a stack system, the network device comprising:
- a processor for executing a file transfer protocol (FTP) server slave process stored in a memory, the FTP server slave process comprising:
- a notification receiving unit and a transfer unit;
- wherein
- the notification receiving unit is to receive a file transfer notice from an FTP server master process;
- wherein the file transfer notice instructs the network device to take over download of a file which is requested by the file transfer request and is in a chassis of the network device;
- the transfer unit is to, after the notification receiving unit receives the file transfer notice, take over execution of transmission of the file through a data link to transfer the file between the network device and the FTP client.
