C/C-ISO/IEC ISP 10612-8-99 (R2008)
détails du produit
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 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, and this part of ISO/IEC ISP 10612 defines the profile RD53.53.
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:
RD53.53 Relaying the MAC service, using transparent bridging, between Token Ring LAN subnetworks.
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 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.
