Which of the following are WAN optimization technologies provided by SD-WAN?

Huawei’s SD-WAN solution includes WAN optimization technologies to improve performance. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

A: Packet loss mitigation (e.g., FEC/A-FEC) recovers lost packets.

B: Transmission optimization enhances link efficiency (e.g., via compression).

C: Data optimization reduces bandwidth usage (e.g., deduplication).
