UAFX Part 84: Profiles - 6.6.3 UAFX Networking Facets

This clause defines facets for Bridge Components, End Station Components, IA-stations, and UAFX Stations illustrated in Figure 5.

Figure 5 – Structure of Bridge and Station Component Facets

6.6.3.2 Base Bridge Component Facet

Table 32 describes the details of the Base Bridge Component Facet.

This Facet describes the requirements common to all products containing bridge functionality. It constitutes a minimal basis that can be relied on for any network consisting of UAFX Stations, including inherited functionality from the IA-station Facet, handling of VLAN IDs and priorities, and Remote Management. It also introduces minimum quantities for queues and VLAN IDs.

6.6.3.3 Advanced Bridge Component Facet

Table 33 describes the details of the Advanced Bridge Component Facet.

This Facet builds on the Base Bridge Component Facet and adds requirements for implementing more advanced network infrastructure capabilities. In particular, it requires time synchronization, mechanisms for network boundary protection, expedited traffic for real-time applications (preemption), and engineered loop prevention. It also introduces minimum quantities for queues, preemption fragment size, and egress buffer size.
