The cloud network platform can provide software-defined network controller ZENIC vDC controller, high-performance virtual bridge DVS, virtual border gateway SDN vGW and software load balancer SLB.
The ZENIC vDC controller is a carrier class cluster controller product developed by ZTE for the cloud data center. It is designed for the application scenarios of the telecom cloud (NFVI), private cloud, public cloud and hybrid cloud. It works with the service orchestrator and cloud platform to provide end-to-end virtualized network solution. The ZENIC vDC controller is northbound to the VIM/Openstack cloud platform, accepts the invocation of the cloud platform, and converts the network service requirements into the forwarding plane model. Through the management and control of routers, switches, vSwitch, smart NICs and firewalls, the ZENIC vDC controller provides automatic end-to-end distribution of network services, so that the network can be linked with the cloud. The ZENIC vDC controller provides three-system cluster to prevent single-point failure and dual-system split-brain. The controller cluster and the forwarding device are decoupled strictly. The failure of the controller cluster does not affect the operation of the forwarding plane. The controller provides a variety of intelligent fault location and analysis functions to improve the operation and maintenance efficiency and ensure the high sustainability of services.
High-performance virtual network bridge DVS, a high-performance carrier-class virtual network switch launched by ZTE, provides access capability to the virtualized server. Based on the open source OVS architecture and DPDK technology, some telecom customized requirements are realized, and the high performance layer-2/layer-3 network functions are finally provided. It can serve as VTEP, supports SDN, has high interoperability and can be interconnected with third-party SDN controller. It supports application scenarios that require live migration, has software flexibility, and facilitates subsequent evolution.
The Virtual Edge Gateway (SDN vGW) is a carrier-class software gateway developed by ZTE. It flexibly provides border gateway services in the form of VMs/containers on the cloud platform, and implements L2 and L3 forwarding capabilities of the data center. The can be deployed on a general server without special dependence on hardware, and can be flexibly expanded or reduced as required. It can serve as SDN GW to provide public network services and access public network for the cloud. Together with the lightweight ZENIC vDC controller and the software load balancer, it can provide pure soft solutions, which can be flexibly applied in small-scale scenarios.
The software load balancer SLB is deployed on the cloud platform as a VM/container, and balances traffic distribution and scheduling among multiple cloud servers to improve the reliability and throughput of the application system. SLB includes traditional TCP/UDP-oriented service and application TCP/UDP-oriented service. Software deployment in forms can effectively reduce costs, and flexible features can rapidly adapt to increasingly fast changing service requirements, reduce hardware dependency, and provide flexible capacity expansion and reduction capabilities.
