Scope
1.1
General ISO/IEC ISP 10612 is applicable to interworking units concerned with operating in the Open Systems Interconnection (OSI) Local Area Network environment. It specifies a combination of OSI standards that collectively provide a MAC relay function. This part of ISO/IEC ISP 10612 is applicable to interworking units operating between CSMA/CD LAN subnetworks.
ISO/IEC ISP 10612-1 specifies the relay function and LAN subnetwork-independent requirements, ISO/IEC ISP 10612-2 specifies the CSMA/CD LAN subnetwork-dependent requirements, and th is part of ISO/IEC ISP 10612 defines profile RD51.51.
1.2
Provision 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:
RD51.51
Relaying the MAC service, using transparent bridging, between CSMA/CD LAN subnetworks.
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 part of ISO/IEC ISP 10612 may include more attachments to CSMA/CD LAN subnetworks with a reference point corresponding to each.
This part of ISO/IEC ISP 10612 specifies the required functions from the supporting protocol stack shown in figure 2.
