CAN/CSA-ISO/IEC ISP 10613-6-99 (R2008)

This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10613-6:1995. 1 Scope 1.1 General This International Standardized Profile is applicable to interworking units concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI base standards that collectively provide a Network Relay function for the connectionless-mode Network Service. This part of ISO/IEC ISP 10613 specifies the RA51.54 profile, which is applicable to interworking units operating between CSMA/CD LAN subnetworks and FDDI LAN subnetworks. 1.2 Position within the taxonomy The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10613 defines the profile: RA51.54 Relaying the Connectionless-mode Network Service between CSMA/CD LAn subnetworks and FDDI LAN subnetworks. 1.3 Scenario Figure 1 illustrates the configuration of systems to which the RA51.54 profile is applicable. The figure shows two reference points, but an implementation of this profile may include more attachments to CSMA/CD and FDDI LAN subnetworks, with a reference point at each.
