ZENIC vDC Controller Introduction

SDN is an open, programmable network architecture with separated forwarding & control and centralized management & control. It is the mainstream trend in the data center network. ZENIC vDC Controller is ZTE's carrier-class cluster controller. It focuses on the SDN demand of cloud data center and is applied to such application scenarios as private cloud, public cloud, The continuous rise of new services such as 5G, internet of things, big video and cloud services has brought great challenges to traditional data centers. The ZENIC vDC controller is a carrier-class cluster controller product launched by ZTE. It is oriented to the application scenarios of telecom cloud(NFVI), private cloud, public cloud and hybrid cloud. In combination with service orchestrator and cloud platform, it provides the end-to-end SDN solution. ZENIC vDC controller's system architecture is 3-server cluster deployment mode, any single node off-line does not affect the work of the controller cluster; the controller cluster and the forwarding equipments are strictly decoupled, and the loss of the controller cluster does not affect the work of the forwarding plane. The ZENIC vDC controller’s high-reliability architecture  ensuring high service reliability.

Major Function

  • Fully programmable architecture

    The kernel of the ZENIC vDC controller is based on the unified ZTE platform, and the components can be dynamically loaded and unloaded. It can be programmed at two layers: Local API and northbound interface.

  • Distributed Controller Cluster

    The ZENIC vDC controller supports distributed controller cluster. The controller cluster consists of at least three controller nodes and provides the control plane with high availability. The scale of a controller cluster can be selected according to network requirements.

  • Built-in network virtualization

    The ZENIC vDC controller supports different layers of network virtualization capabilities. Include tenant virtualization, VRF-based route virtualization, VNET-based network virtualization, interface virtualization.

  • Supporting Distributed Routing

    The ZENIC vDC Controller supports distributed routing, that is, the fabric network forwards the east-west traffic and south-north traffic according to the host route flow table. Each OFS in the network is equal and can serve as the router. The distributed routing solution simplifies network design and avoids sensing and special configuration of the controller for different OFS devices. Besides, communication with adjacent servers avoids traffic detour and reduces network communication load, which satisfies the explosive east-west traffic requirement in current data centers.

  • Rich built-in network management functions

    The ZENIC vDC controller has many built-in network management functions of Web GUI, so that the administrator can manage the network status and locate the fault. The functions include: topology visualization, alarms, end-to-end fault diagnosis, protocol tracing.
