HP OSI Transport Services/9000
HP OSI Transport Services/9000 (OTS/9000) is the OSI networking stack of HP-UX. It
provides functions of OSI Layers 3 (Network), 4 (Transport), 5 (Session), 6 (Presentation)
and ACSE/ROSE over X.25, FDDI, and IEEE802.3 LAN interfaces. It also provides
RFC1006 that allows users to run OSI Services over TCP connections. Applications can
use OTS/9000 via Application Program Interfaces (APIs) to layers 4, 5, 6, and
ACSE/ROSE application entities.
Summary of Change
HP OTS/9000 version C.12.00 provides the following feature:
• otsshownsaps
When otsshownsaps is executed, it shows the list of Network Service Access Point
addresses (NSAPs) configured on OTS/9000. In addition, the new enhancement
shows the following:
— state of the NSAP (whether it is static or dynamic)
— interface on which the NSAP is configured
— the NSAP’s alias
• Expedited data transfer on RFC1006 subnet
This is an enhancement for support of transferring expedited data on RFC1006
subnet using the XTI API interface. New features are as follows:
— Support for sending and receiving of expedited data on RFC1006 subnet, using
XTI interface.
— Support for sending user data as a part of Connect Request PDU, using XTI
interface.
— Support for 64K size Data Transfer PDUs.
— Provides means to enable & disable the feature to support expedited data on
RFC1006 subnet.
Impact
• otsshownsaps
With this feature, it is now possible to find the state of an NSAP, as well as the
interface to which the NSAP is configured. Where possible, the NSAP’s alias is also
shown.
• Expedited data transfer on RFC1006 subnet
With this feature, it is now possible to transfer expedited data from XTI applications
over the RFC1006 subnets. It is also possible to send user data as a part of the
Connect Request PDU.
