Information technology - International Standardized Profile RD - Relaying the MAC service using transparent bridging - Part 9: Profile RD53.54 (Token Ring LAN - FDDI LAN)
This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10612-9:1995. 1 Scope 1.1 General ISO/IEC ISP 10612 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 MAC relay
function between LAN subnetworks. This part of ISO/IEC ISP 10612 is applicable
to interworking units operating between Token Ring and FDDI LAN subnetworks. ISO/IEC ISP 10612-1 specifies the relay function and LAN subnetwork-independent
requirements, ISO/IEC ISP 10612-3 specifies the Token Ring LAn
subnetwork-dependent requirements, ISO/IEC ISP 10608-14 specifies the FDDI LAn
subnetwork-dependent requirements, and this part of ISO/IEC ISP 10612 defines
the profile RD53.54. 1.2 Position within the taxonomy The taxonomy of OSI profiles is defined in ISO/IEC TR 10000-2. This part of
ISO/IEC ISP 10612 defines the profile: RD53.54 Relaying the MAC service, using transparent bridging, between a Token
Ring LAN subnetwork and an FDDI LAN subnetwork. 1.3 Scenario Figure 1 illustrates the configuration of systems to which this part of ISO/IEc
ISP 10612 is applicable. The figure shows two reference points, but an
implementation of this profile may include more attachments to Token Ring LAn
and FDDI LAN subnetworks with a reference point corresponding to each.
