Virtualization Data Center Network Solution

SDN vDC Network Introduction

ZTE SDN vDC Network Solution integrates SDN technology seamlessly with OpenStack and K8S to build a multi-tenant virtualized data center (VDC) network through CUPS, centralized management and control, and open and programmable network architecture. The whole network is based on the overlay architecture of SDN. With the ZENIC vDC controller as the core, it supports open source OVS, self-developed DVS and 5900(X) series switches as VTEP. It supports M6000-S series routers, 9900(X)/5900(X) series switches, VEG virtual routers and SmartNIC as SDN gateways. Through external cooperation, it supports automatic service distribution of mainstream software and hardware FW, LB and VPN in the industry. To meet diversified requirements of different traffic, cost model and transformation/creation, ZTE provides hybrid overlay, host overlay and network overlay solution to protect the customer's investment to the maximum extent. It has built-in microsegmentation security and automatic security policy for mutual access among multiple security domains, supports the interconnection of multiple DCs and centralized control of remote miniaturized DCs, to provide customers with intelligent, open and secure cloudified DC networks.

Solutions Advantages

Super-large-scale networking

The controller cluster supports 2K VTEP, meeting the capability of super-large DC.

Automatic service deployment

With all devices in the network supporting automatic deployment and following VM migration policies, network services can be rapidly innovated and deployed.

Intelligent O&M

End-to-end fault detection and accurate service quality detection, effectively reduce network maintenance costs.

Customer Value

Supports multiple networking modes to meet access requirements in various scenarios.

Fully supports multiple networking modes such as hybrid Overlay, host Overlay and network Overlay. It supports any combination of four roles: software VTEP, hardware VTEP, hardware gateway and software gateway. It also supports unified access of multiple loads such as VM, bare metal, SR-IOV and container, ensuring flexible networking and meeting the requirements of future network evolution.
Unified management of edge DCs, improving network utilization and reducing network O&M costs

Supports centralized SDN controller multi-fabric network management and distributed multi-controller lightweight network management. It manages and controls discrete MEC resources in a centralized manner, thus achieving centralized virtual network configuration policies and efficient and convenient O&M. Working with cloud platform. It supports multi-MEC inter-domain end-to-end service orchestration to provide open network capabilities and services, enable 5G edge applications, and accelerate service on-boarding.
All-round carrier-grade enhancement, providing high-reliability SDN

Network-level high reliability: SDN gateway dual-active deployment, TOR MC-LAG deployment and ECMP multi-path mode of core switch improve network reliability. It also supports all-round BFD protocol to implement millisecond-level fault service switching.
High-reliability SDN: ZENIC vDC controller cluster works together with remote cluster disaster recovery solution, provides the northbound-southbound consistency reconciliation capability, meeting the reliability requirements of service-level, equipment-level and site-level disaster recovery.
Secure and trusted: It supports carrier-grade right-based and domain-based security protection, and introduces micro-isolation and security protection software to establish a comprehensive security protection system for the cloud DC.
Intelligent network deployment and O&M, speeding up service onboarding

The solution provides zero touch deployment tools to enable automatic device launch and automatic provisioning based on the intent network, achieving fast network deployment and service onboarding. It provides intelligent O&M tools which supports various O&M methods such as configuration check, path detection, and radar scanning, to implement end-to-end performance monitoring and management and minute-level fault delimitation and location, to improve O&M efficiency.
