Scope

1.1

General This International Standardized Profile is applicable to End Systems concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI standards, which collectively provide the connection-mode Transport Service using the connection-mode Network Service.

This part of ISO/IEC ISP 10609 defines the TC54 profile which is applicable to the provision of the OSI connection-mode Transport Service using the OSI connection-mode Network Service in an End System attached to an FDDI LAN subnetwork.

1.2

Position within the taxonomy The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10609 defines the profile:

TC54

Connection-mode Transport Service over connection-mode Network Service over FDDI LAN subnetworks.

1.3

Scenario Figure 1 illustrates the configurations of systems to which the TC54 profile is applicable.

This part of ISO/IEC ISP 10609 specifies the required functions from the supporting protocol stack shown in figure 2.

This part of ISO/IEC ISP 10609 does not specify the required functions for relays.
