DT Cloud Platform CD-WAN

Simplifies the management and operation of a Wide-Area-Network

Higher-performance WANs using lower-cost internet access

Replace expensive private WAN connection technologies such as MPLS

With the continuous cloudification of enterprise IT architectures and widespread use of public clouds, increasingly more enterprises are starting to shift their infrastructures (such as enterprise data centers) to the cloud, abandon traditional closed IT architectures, and instead use open network architectures. To further this, enterprises’ mission-critical applications are migrated onto the cloud, such as the office, production ERP system, and sales system. Under this situation, enterprises increasingly rely on the public cloud services and prefer to access key applications required for daily office work from the cloud through the Internet.

SD-WAN Solution addresses the issues facing enterprise networks, including closed WAN architectures, difficult service experience guarantee, slow service rollout, and difficult O&M. This solution provides full-scenario on-demand interconnections between branches, between branches and data centers, and between branches and clouds. With compelling features such as application-based intelligent traffic steering and acceleration as well as intelligent OM, the SD-WAN Solution redefines full process service experience in enterprise WAN interconnections.

Architecture of SD-WAN Solution

The overall architecture SD-WAN Solution comprises the network connection layer, control layer, and management layer.

Network Connection Layer

Enterprises deploy cost-effective routers and use overlay technology to build full network interconnections between the headquarters, branches, and public or private clouds on demand through links such as Internet links and traditional private lines.

Control Layer

Routers (RRs) c policy provisioning, route transfer between sites in each area, and inter-area network interconnection.

Management Layer

Central Management System implements full-process management on enterprise interconnection services. In the southbound direction, configuration and orchestration of different virtual private network (VPN) topologies, as well as management and provisioning of network service policies.
