MINI-LINK PT 2010 Functions – Ethernet
In a network, it is important that only one set of priority definitions is used (for
example, IEEE 802.1D-2004). Otherwise, the handling of Ethernet frames
and the mapping to egress queues can differ between network elements. The
outcome of this scenario is a non predictable behavior for the different traffic
types (for example, voice).
Priority Code Point (PCP)
The Priority Code Point is the three bits in the Ethernet header that is used to
carry the priority value and coloring information for the Ethernet frame. The
priority information is mandatory while coloring information is only applied when
the Ethernet flow is policed.
MINI-LINK PT 2010 Priority Handling
MINI-LINK PT 2010 does not currently provide UNI functionality to re-map
user/customer priority to network priority, but can be setup to act on quality
information, either in the customer or the network domain. This is shown in
Figure 7 below and further explained in Section 6.1.4 on page 18.
