Abstract

Disclosed is a program for JavaOS to boot from multiple servers. Boot server is DHCP server which runs in WindowsNT server. It is desired that each client boots from primary boot server normally, and in case of primary server is out of service, client should boots from secondary server. It is realized to add a new DHCP boot priority option for DHCP server configuration.

JavaOS Multiple Boot Server (Win32) Support with Priority

   Disclosed is a program for JavaOS to boot from multiple
servers.  Boot server is DHCP server which runs in WindowsNT server.
It is desired that each client boots from primary boot server
normally, and in case of primary server is out of service, client
should boots from secondary server.  It is realized to add a new DHCP
boot priority option for DHCP server configuration.

   Current JavaOS uses PXE and DHCP to boot, and client just
wait for server response.  So it is possible to configure two or
more WindowsNT DHCP boot servers for JavaOS client.  But it is
impossible to boot from the specific server.  If any of servers
respond to the client, then the server will be the boot server.  It
is desired that each client have primary boot server, secondary boot
server, ... and so on.  If server can have primary and secondary
attribute from a client, it can be OK.  And PXE seems not be able to
configure the specific boot server.  IBM NetworkStation can have a
capability to specify primary, secondary and third boot server in the
client configuration, but it is not exist in PXE.

   To realize primary and secondary boot server functionality
for our system, need to add a new parameter in DHCP configuration
such like boot priority option, and if it is specified as 1, this is
primary boot server.  If 2 or more larger number, it means this is
not a primary server.  If option is 1, the DHCP will respond
