What are the advantages of Huawei's business mobility solution compared with the AD-CAMPUS solution of other vendors? (Multiple choice)

• A.Comply with IETF UAPC standards
• B.Mobile users are tightly coupled with IP addresses and VLAN policies
• C.The solutions of other vendors require the planning of a large number of basic network functions such as VLANs, VxLANs, and IP segments according to user groups. When user classification changes or new user groups are added, the equipment needs to re-plan the basic network configuration, which cannot be automated.
• D.All vendors' access, edge, and core devices need to support VxLAN, and the network needs to be bound to the same brand, which makes deployment complex and costly.
• E.Free mobility policies are defined using UCL, which is more flexible than traditional ACLs and supports a larger user base.

The link utilization rate of traditional networks is only 20%-30%. Huawei's agile wide area solution is based on the SDN architecture, which integrates factors such as bandwidth, latency, and cost, and globally calculates routes to achieve reasonable scheduling of business traffic, thereby increasing network utilization to more than 70%.
