Performance Comparison
Service Feature	IP VPN with infrastructure all over China
Access Mode	Single device connected to the POP via a single line	Dual Cisco devices are connected to different operator lines. The primary and backup systems operate independently.
QoS	Prioritized QoS management is implemented on real-time data and common data.	In addition to the QoS management, important data is transmitted on the primary line, and less important data is transmitted on the backup line, implementing mutual backup.
Scalability	High. When an access point is added, only one physical line is needed to realize multi-point interconnection.	High. Physical lines are interconnected at multiple points, the backup mechanism allows access of any lines, and data streams are balanced among lines.
Stability	High	High. Dual devices and dual lines provide double insurance and uninterrupted operation.
Flexibility	High. Supporting any type of line supplied by any operator
Bandwidth Utilization Rate	All data is transmitted on the primary line, which is easily overloaded.	Highly flexible and supporting multi-service concurrent transmission. The backup line is used to transmit low-priority data, which improves the bandwidth efficiency.
Bandwidth Utilization Rate
Local loop	Private line of China Telecom (metropolitan Ethernet, optical fiber, and private line) + SSL mobile user access	Dual Cisco devices are equipped. The primary line mainly uses the optical fiber, and the backup line is compatible with any type of line access.
