[ 5. File Sharing Services]
EMBEDDED LAN FILE SHARING SERVICES
═════════════════════════════════════════════════════════════════════════
The Embedded LAN File Server and Embedded LAN redirector allow one target
running the Embedded DOS operating system to share its file systems with
other targets on the LAN.
THE FILE SHARING REDIRECTOR
The Embedded LAN Redirector translates requests for remote file I/O into
streams of protocol on the LAN. This component installs on any 80x86
Embedded DOS system and intercepts I/O requests associated with network
drives, routing the requests to designated file servers over the TDI
Transport Driver Interface. Network drives are created using the NET
program (a full screen utility), the NET USE command from COMMAND.COM,
or via INT 21h software interrupt from an application program.
THE FILE SHARING SERVER
The File Server component of Embedded LAN accepts incoming requests
from its Transport Driver Interface and interprets them as file I/O
requests. These requests are handled by executing local I/O operations,
and then returning the results to the requesting node through protocol.
Each open file or search handle is assigned a separate TDI connection,
for maximum parallelism; this allows several threads to perform truly
concurrent I/O to different files simultaneously.
