Scenarios

Four typical types of scenarios for Layer 2 and Layer 3 networks are described as follows.

Layer 2 Network​

Scenario	Fabric​ (Backbone)	Access (Last Mile)	Access (Last Mile)	Access (Last Mile)	OnRamp​ (First Mile)
	Private Connect​	Port	Cross Connect	Local Loop	Cloud Connect​
IDC to IDC​	√	√	√
Office to IDC​	√	√	√	√
IDC to Cloud​	√	√	√		√
Office to Cloud​	√	√		√	√

Layer 3 Network

Scenario	Fabric​ (Backbone)	Access (Last Mile)	Access (Last Mile)	Access (Last Mile)	Access (Last Mile)	OnRamp​ (First Mile)
	Cloud Router​	Port	Cross Connect	Local Loop	Virtual Edge	Cloud Connect​
IDC to IDC​	√	√	√
Office to IDC​	√	√	√		√
IDC to Cloud​	√	√	√			√
Office to Cloud​	√				√	√

Note

• IDC refers to Internet Data Center.

• If your data center is too far to establish cross connect to the equipment port in our SDN POP, you can choose to deploy a local loop.
