As the Internet becomes an integral part of our daily life and the mobile Internet and service-oriented cloud computing technologies become increasingly mature, Internet traffic has experienced explosive growth. A survey shows that IP traffic from DCs around the world increases at an annual growth rate of 33% on average. The data traffic in DCs is expected to reach 4.8 ZB in 2016. This poses significant challenges to DCNs, infrastructure for service provisioning. Huawei holds that future networks have to adopt hierarchical DC deployment and DC-centric restructuring to provide ms latency service experience.
Among the three components of Huawei's DC-centric network solution:
CloudFabric 3.0 provides easy-to-use SDN-based drag-and-drop GUIs, allowing service providers to perform tenant-oriented service provisioning with one click. CloudFabric 3.0 uses HUAWEI CE12800s (each with a switching capacity of 160 Tbit/s, three times the industry average) as DC core switches to help operators build high-performance and highly elastic DCNs.
DCI provides SDN-based E2E IP+optical synergy, allowing for automated service provisioning and rapid optimization within several minutes.
CloudVPN expands the business reach of operators to enterprise networks, helping operators to increase customer loyalty and business revenue through NaaS.
