CAN/CSA-ISO/IEC ISP 10608-4-99(R2003)

1. Scope1.1General ISO/IEC ISP 10608 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 connectionless-mode Network Service.This part of ISO/IEC ISP 10608 is applicable to the provision of the connection-mode Transport Service in End Systems attached to a Token Ring LAN subnetwork from which the standardized connectionless-mode Network Service can be made available.1.2Position Within the Taxonomy The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10608 defines the profile: TA53: Connection-mode Transport Service over connectionless-mode Network Service over a Token Ring LAN subnetwork.1.3Scenario Figure 1 illustrates the End System configurations to which the TA53 profile is applicable.This part of ISO/IEC ISP 10608 specifies the required functions from the supporting protocol stack shown in table 1.
