Transport Optional Upgrade Release (TOUR) 3.1 Release Notes

Announcement

Functionalities for Transport and STREAMS are delivered as part of the HP-UX operating

system. Transport Optional Upgrade Release (TOUR) 3.1 is an additional Web release

supported by HP-UX. TOUR 3.1 delivers Transport and STREAMS functionality

independently of major HP-UX releases.

TOUR 3.1 provides a number of Transport enhancements that contribute to the overall

performance and scalability of networking with HP-UX. TOUR 3.1 contains the following

components:

• STREAMS framework (introduced in TOUR 3.0)

•HP-UX IPv4

• HP-UX Mobile IPv6 (introduced in TOUR 2.0)

•HP-UX IPv6

• PPPoE

•PPPv6

• Router Advertisement Daemon

TOUR 3.1 also provides enhancements to the HP-UX STREAMS framework. TOUR 3.1

replaces the original HP-UX STREAMS functionality. However, when the STREAMS

functionality installed as part of TOUR 3.1 is removed, the system reverts to the original

HP-UX STREAMS functionality.

Later versions of TOUR supersede previous versions. All features available in a TOUR release

will be included independently in a later HP-UX release.

WARNING Defect fixes for ARPA Transport and STREAMS are included in TOUR

releases. Once TOUR is installed, it is CRITICAL that NO ARPA

Transport or STREAMS patches are installed on the system.

Otherwise, defect solutions and subsystem dependencies could be lost.

Defect fixes and new functionality for ARPA Transport and STREAMS

MUST ONLY BE APPLIED via future TOUR releases.

The TOUR bundle may contain enhancements and features that are incompatible or not

included in ARPA Transport or STREAMS patches.
