3 Global Data Center Traffic Growth The provisioning of planned inter-dc services takes several days to weeks. Burst services such as big data analysis and cloud computing bring heavy IDC workloads, resulting in unpredictable service quality deterioration. The global DC traffic in 2019 is predicted to rise to 10.4 ZB, at the CAGR of 25%. Service faults should be quickly located. The KPI for level-1 fault recovery must be less than 2 hours. Source: Cisco, Fast service provisioning Flexible service pipes Simplified Operations Services provisioned in minutes/seconds. Dynamic BW adjustment for scheduled workload operations. Workload-network service scheduling automation. Quick, efficient and automated fault recovery. 3

4 DCI Network in Eastern China Huawei BoD Other apps Huawei T-SDN Challenge Inter-IDC operations underpin almost all Baidu services. All inter-idc traffic is forwarded by the super IDC, resulting in IDC load imbalances and a requirement for excess transport capacity. Common IDC A Super IDC OTN network Common IDC B Transport-SDN IDC Network App: Service departments such as Baidu finance and video can provision services online, simplyfing operations. Bandwidth calendaring: Bandwidth can be added or deleted at planned times for planned IDC operations. Load balancing: Bypass function based on OTN crossconnection improves global network efficiency. 4
