Disk I/O Support
RARP/ARP Protocol Modules
The Reverse Address Resolution Protocol (RARP) basically consists of:
❏An
❏The node awaiting an answer
❏The RARP server filling an Ethernet reply packet with the target's Internet Address
❏The RARP server sending it to the node
The Address Resolution Protocol (ARP) basically provides a method of converting protocol addresses (e.g., IP addresses) to local area network addresses (e.g., Ethernet addresses). The RARP protocol module supports systems which do not support the BOOTP protocol (next paragraph).
BOOTP Protocol Module
The Bootstrap Protocol (BOOTP) basically allows a diskless client machine to discover:
❏Its own IP address
❏The address of a server host
❏The name of a file to be loaded into memory and executed
TFTP Protocol Module
The Trivial File Transfer Protocol (TFTP) is a simple protocol to transfer files. It is implemented on top of the Internet User Datagram Protocol (UDP or Datagram) so it may be used to move files between machines on different networks implementing UDP. The only thing it can do is read and write files from/to a remote server.
