Customer Edge

Why the Customer Edge?

Feasibility Some functions must be placed at the customer site: Loopbacks, end-to-end security, traffic conditioning, encryption, WAN optimization
Performance · Some functions perform better at the customer site: End-to-end QoS, QoE     application monitoring

· Some functions may degrade due to network constraints: Bandwidth, delay, availability

Economics Higher performance and resiliency requirements may lead to a cost increase, offsetting data centers’ economies of scale
Policy · Some functions need to remain close to the customer’s due to corporate policies on privacy, security and access authorization

· Regulatory restrictions (e.g., on moving data across jurisdictions) may also apply
