Which of the following statements are true about the wireless traffic forwarding modes on a fabric wireless network?
A.
Tunnel forwarding facilitates centralized management and control of wireless traffic.
B.
Direct forwarding is more efficient.
C.
Tunnel forwarding has the disadvantage of traffic detour, which increases the forwarding performance pressure on the WAC.
D.
Direct forwarding is not suitable for scenarios that have high requirements on roaming performance. This is because roaming performance deteriorates slightly when a STA roams across edges.
Huawei supports two main forwarding modes in its wireless architecture:
Tunnel Forwarding (A, C): All data traffic is encapsulated in CAPWAP and sent to the WAC. This simplifies security policy enforcement but causes "traffic detour" and places a heavy processing load on the WAC.
Direct Forwarding (B, D): APs switch traffic locally. This is highly efficient and reduces core congestion. However, because traffic is released at the edge, maintaining session continuity (roaming) across different Layer 3 boundaries can be more complex, potentially leading to slight performance dips during inter-edge handovers compared to centralized tunneling.
