Data Fields | |
uint16_t | retransmissions |
This member defines how many attempts are made to send a network packet to the server. | |
uint16_t | server_port |
This member defines the port on which the server is listening for incoming connections. | |
uint32_t | timeout |
This member defines the maximum time in milliseconds the client waits for an answer packet from the server. | |
uint32_t | first_timeout |
This member defines the maximum time in milliseconds the client waits for the first answer packet from the server. | |
tftp_options | options |
This member represents the options to be sent to the server. | |
This structure represents configuration value used by the TFTP client.
As defaults the values suggested in RFC 7440 are used.
uint32_t tftp_net_config::first_timeout |
This member defines the maximum time in milliseconds the client waits for the first answer packet from the server.
The first_timeout
is used instead of the regular timeout
for the first wait-period directly after the client sends a packet for the first time to the server. That is, this is the timeout of the first re-transmission. For any following re-transmissions of the current packet the regular timeout
is used.
The default value is 400ms.
tftp_options tftp_net_config::options |
This member represents the options to be sent to the server.
These option values are sent to the server. Yet, the server may
If the server rejects a request with options, the current client implementation will automatically send a second request without options. Hence, the user should be aware that the actual file transfer may not use the option values specified here.
uint16_t tftp_net_config::retransmissions |
This member defines how many attempts are made to send a network packet to the server.
Repetitions occur when the server does not response to a packet send by the client within a timeout period. When the here defined number of repetitions is reached and the server does still not respond, the connection is considered broken and the file transfer is ended with an error.
The default value is 6.
uint16_t tftp_net_config::server_port |
This member defines the port on which the server is listening for incoming connections.
The default port number is 69.
uint32_t tftp_net_config::timeout |
This member defines the maximum time in milliseconds the client waits for an answer packet from the server.
If the time out is exceeded, the client will re-transmit the last packet it send to the server. In case window_size
is larger one, several packets may subject to re-transmission.
Note that this timeout applies only after the first re-transmission of a packet. The timeout till the first re-transmission is first_timeout
.
The default value is 1000ms.
