Manually Operation Results Long TTM IP Topology Optical Topology Manually Planning Manually Interaction Manually Provisioning Planned, designed and operated separately By separate teams ChinaNet: Network expansion needed by every 6 months. It takes months to modify network! 3. Low Network Utilization Brings CAPEX Waste Expected Network on Planning Real Network Utilization + + = CAPEX Waste Complicated Routing Protocols Unpredictable Protection and Restoration Unpredictable Traffic Pattern HUAWEI TECHNOLOGIES CO., LTD.
