Enhancements to Networking Features

A brief description of the enhancements to the networking features follows:

Support for IPv6

Internet Protocol version 6 (IPv6) is the standard for next generation IP networks (particularly for 3G mobile networks).

IPv6 adds increased address space and improves Internet functionality using a simplified header format. It includes support for authentication and privacy, autoconfiguration of address assignments, and new quality-of-service capabilities. See "IPv6" for more information.

Messaging

The messaging feature has been extended to include asynchronous communication in addition to the synchronous RPC model available in earlier versions of the ChorusOS operating system. The new messaging service also supports multithreading. See "RPC Extensions" for more information.

DHCP and TFTP

The Dynamic Host Configuration Protocol (DHCP) allows the ChorusOS system to obtain network information, such as a dynamically assigned IP address, or the IP addresses of the default router and name server, from a DHCP server at boot time.

The TFTP daemon allows you to boot a ChorusOS target from the network (using bootmonitor), with the DHCP and TFTP server running on a ChorusOS machine. The tftpd daemon is a standalone daemon. The tftp command is used to transfer files in the same way as ftp.

For more information on the implementation of these protocols, refer to "Network Administration Commands and Daemons" in the ChorusOS 5.0 System Administrator's Guide.

NTP for ChorusOS

Allows you to manage precise time and network clock synchronization in a network environment. The inclusion of NTP in the ChorusOS operating system provides increased time precision. See "Network Time Protocol (NTP)" for more information.
