An FTP Code Library by Hillstone Software

HS TFTP is a software library in C (supplied with full source code) which implements Trivial File Transfer Protocol (TFTP) over UDP socket layer according to RFC 1350. Support for client and server side for both file get and put are provided. Up to 100 concurrent sessions are supported. The use of HS TFTP software library is royalty free.

HS TFTP is supplied in a form of full ANSI C source code and binaries and would require no or minimal integration effort by the customer

Features:
- TFTP server and client
- Defaults to 100 concurrent sessions
- 512 packet size
- TFTP File upload
- TFTP File download

MODEL OF OPERATION:
When user application initlialises Hs TFTP library, it provides interface callbacks for the services used by HS TFTP protocol module: timer management, memory management and event callbacks. This architecture makes it easy to port HS TFTP protocol module to any environment. HS TFTP internally at a lower layer interfaces to HS Sock library which provides UDP transport services. User application need not worry about Winsock - HS TFTP does all transmission, reception and event handling over socket layer.

TFTP module handles all protocol information flow, error recovery, acknowledgements, timeouts and so on. When it is appropriate to send next block of data HS TFTP will get next memory block from user application. Similarly, when data has been received HS TFTP module will get the next block of memory from user application to store data into.
