First Claim
Patent Images
1. 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.

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.

6. 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. - View Dependent Claims (7, 8, 9)

10. 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. - View Dependent Claims (11)

12. 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;
whereinthe 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. - View Dependent Claims (13, 14, 15)
