Intra-cloud network: adopt BGP, EVPN, VxLAN architecture to deploy cloud-data center; and combine SDN controller to achieve the separation of transferand control.

Cloud management network: standard network architecture used for cloud management service applications and public service network access.

Management network: standard network architecture used for management port access in network equipment.

Core network: standard network architecture used for interconnecting various data center networks.

Intra-cloud network (production environment), cloud management network and management network (management environment) have logical isolation and will not affect each other.

Cloud platform: we adopt the commercial H3Coud products from current mainstream resource pool (OpenStack) to obtain that cloud platform is able to provide interfaces, service management, automatic dispatch, and resource and service guarantee for business/network administrators and tenant administrators. Components like Nova, Neutron and Cinder, with realized control and management when interacting with other components in corresponding resource, will be used to convey the computing, storage and network resource of virtualization and pooling in data center. The interaction of different components attains a coordination of the resources.

computing resources: we install H3C CVK system on X86 server to provide a management end for server virtualization, which is bare-metal management server.

Network control layer: VCF Controller (VCFC for short) is the core of the overall SDN controller solution. VCFC completes network modeling and instantiation, and cooperates with virtual and physical network to provide pooling and automation of network resources. At the same time, it boosts a network-wide view and is a key component to realize SDN network.
