What is SD-WAN? Software-Defined Wide Area Networks (SD-WANs) are an ideal way of eliminating the use of excessive networking hardware by introducing a software approach to traffic monitoring and management. By adding a virtual overlay that is packed full of intelligence VeloCloud facilitates a network administrator to remotely program edge appliances connected to any enterprise or service provider network via a central controller.
This reduces provisioning times and eliminates the need to manually configure traditional routers in branch locations individually. Software Defined Networking (SDN) technology principles can be applied to public and/or private Wide Area Network (WAN) connections, which are used to connect enterprise networks over large geographical distances.
SD-WAN and cloud networking technologies simplify and optimise branch office orchestration and connectivity whilst increasing flexibility yet remaining cost efficient. VeloCloud is the first to provide all three elements needed to achieve a Cloud-Delivered SD-WAN: a cloud network for enterprise-grade connection to cloud and enterprise applications; software-defined control and automation; and virtual services delivery.
Seamless Location-To-Location Programming
Deutsche Telekom needed a solution to enable a network operator to be able to program and manage 3D printers and robots in one location from another location after limited training. The orchestration of all the various components needed for 3D printing also had to be automated. Deutsche Telekom already had a highly reliable Multiprotocol Label Switching (MPLS) network with easily manageable Quality of Service (QoS) and Service Level Agreements (SLAs). But the lab needed a way to deploy and get a series of 3D printers running-in a week.
Like Deutsche Telekom, many companies that are working at the leading edge of so many new technologies find themselves stuck in the middle of multiple disruptive digital technology trends, collectively known as Industry 4.0.
- Internet of things
- The Cloud
- Horizontal and vertical system integration
- Big data analytics
- 3D printing
- Augmented reality
These technologies offer significant promise in working together to create more efficient, secure and economical processes. E.g. cyber-physical systems can monitor physical processes, create a virtual copy of the physical world and make decentralized decisions.
However, Deutsche Telekom recognised that building a separate WAN and VPN network on top of their existing infrastructure would be cumbersome, time-consuming and very expensive. Re-designing the network to introduce 3D printing or other robotics into the industrial automation infrastructure was not an option. Deutsche Telekom needed a solution that was agile, low cost and simple with minimal impact to the existing MPLS network.
The VeloCloud Cloud-Delivered SD-WAN Solution
The Silicon Valley lab turned to VeloCloud, to simplify its branch office networking while assuring optimal application performance. Augmenting the existing network using a Software-Defined Wide Area Network as the overlay was the solution. An overlay would provide a separate control network, with its individual SLA, policy management and business policy framework. This solution is easy to implement, whilst still enabling deep visibility into the WAN to get the industrial automation network prototype up and running in the fastest possible time. VeloCloud deployed and activated SD-WAN infrastructure in less than a week.
Introducing a separate control plane and data plane layers allows you to move intelligence from the data plane into the programmable control plane for greater agility. This architecture also operates across any combination of public or private circuits. VeloCloud SD-WAN now provides them with location-location connectivity, ensuring reliable response. Using existing network links between four locations, they laid, installed and connected the VeloCloud Edge devices and VeloCloud Gateways.
“Within the first week we had the VeloCloud SD-WAN set up,” said Sumanth Sathyanarayana, Research Engineer at Deutsche Telekom. “The setup and connectivity was very easy as it is a plug and play solution. We also shipped equipment to the other locations and made similar connections in a very short time.”
Deutsche Telekom SVIC used VeloCloud Orchestrator policy management feature to establish SLAs over secure VPN connections between Berlin and Mountain View. The VeloCloud Orchestrator enables the team to insert network services at the edge, in the cloud, or in a data centers through business policies, which handle optimal gateway selection, distributed QoS configurations, automatic VPN connections, and network services insertion. The team can discover and fingerprint thousands of enterprise and cloud applications quickly and easily to automatically prioritize, insert services and deploy security policies.
“VeloCloud gives agility to the WAN through programmability”, said Sathyanarayana. “Capabilities like automatic WAN link discovery and monitoring eliminate having to configure links and branch locations individually.” Ensuring high performance for robotic commands is achieved using VeloCloud Dynamic Multipath OptimizationTM technology. It aggregates broadband Internet, 4G-LTE, and MPLS circuits with application-aware, per-packet link steering and on-demand remediation to maximize performance over any transport. VeloCloud Cloud-Delivered SDWAN also provides consolidated monitoring and visibility across multiple WAN links and service providers, which greatly simplify management.
With the prototype network for this next generation project in place, Deutsche Telekom SVIC is continuing to validate SD-WAN architecture and capabilities supporting industrial 3D and robotic automation. As it scales SDN capabilities across thousands of miles, the company is adding value to customers and their future network deployments as it delivers resilient, real-time-capable, highly secure network communications that can be ordered and deployed with high predictability at short notice.
