You are working on a VoWLAN design with your customer's wired networking team. How many distinct priority levels do you expect for the voice applications?
A.
1 priority level, but 2 queues (one for uplink traffic, one for downlink traffic)
B.
1 priority level per client and AP pair, so the total number depends on the expected number of clients
C.
1 priority level for voice RTP, 1 priority level for voice control and RTCP
D.
1 priority level for VoWLAN client traffic, 1 priority level for wired VoIP client traffic
In Voice over WLAN (VoWLAN) deployments, it's crucial to differentiate between various types of voice-related traffic to ensure optimal Quality of Service (QoS).Real-Time Protocol (RTP) carries the actual voice payload, while control protocols like RTCP manage session control and quality feedback.Assigning distinct priority levels to these traffic types allows the network to prioritize voice payloads appropriately while still handling control traffic efficiently.
