Abstract
A network traffic management device (NTMD) capable of gracefully handling remote file transfer errors is disclosed. A first local area network (LAN) may include a first NTMD and a client device. A second LAN may include a file server and an optional second NTMD. The first and second LANs are connected by a wide area network. The first NTMD optimizes network file transfer protocol (e.g., CIFS, NFS) operations by locally acknowledging file write command messages from the client device and reliably handling any file transfer errors that may occur by withholding flush data command messages from the client device until determining the locally acknowledged and forwarded file write commands were received by the file server. If any errors are encountered, the first NTMD returns a failed flush message to the client device or terminates the TCP/IP connection between the client device and the file server to indicate the error.
