Data processing network with boot process using multiple servers
First Claim
1. A data processing network comprising at least one client system connected to first and second server systems, the first and second server systems being operable to communicate with the network according to first and second incompatible data communication protocols respectively, the client system being operable to issue, onto the network, a first boot request according to the first data communication protocol, the first server being operable, in response to the client request, to send bootstrap code to the client system, which code when executed on the client causes the client to issue a second boot request according to the second communication protocol for servicing by the second server system.

Abstract
A data processing network has a client connected to first and second servers in which the first and second servers are operable to communicate with the network according to first and second incompatible data communication protocols. The client is operable to issue, onto the network, a first initial boot request (e.g. RPL) according to the first data communication protocol (IEEE 802.2) and the first server is operable, in response to the client request to send BOOTP bootstrap code to the client system. The BOOTP bootstrap code is loaded into client memory and when executed causes the client to issue a BOOTP request for servicing by the second server system.

8. A method of operating a data processing network comprising at least one client system connected to first and second server systems, the first and second server systems being operable to communicate with the network according to first and second incompatible data communication protocols respectively, the method comprising:
-
at power-on or re-boot of the client system, issuing a first boot request from the client system onto the network according to the first communication protocol; and responsive to the receipt of the boot request at the first server system, transferring bootstrap code to the client to cause the client to issue onto the network a second boot request according to the second communication protocol. - View Dependent Claims (9, 10)
