Figure 135. Four Traffic Classes
The Wireless Array’s Quality of Service Priority feature (QoS) allows traffic to be
prioritized according to your requirements. For example, you typically assign the
highest priority to voice traffic, since this type of traffic requires delay to be under
10 ms. The Array has four separate queues for handling wireless traffic at
different priorities, and thus it supports four traffic classes (QoS levels).
Figure 136. Priority Level—IEEE 802.1p (Layer 2)
IEEE802.1p uses three bits in an Ethernet frame header to define eight priority
levels at the MAC level (Layer 2) for wired networks. Each data packet may be
tagged with a priority level, i.e., a user priority tag. Since there are eight possible
