A definition of SD-WAN
SD-WAN or software defined WAN, is a technology based on the broader concept of SDN (software defined networking). It allows enterprises and organizations to configure policies to distribute the network traffic. The central site of any SD-WAN solution has total control of their offices or sites and the traffic which flows through the network, via a Controller. The mentioned Controller can also enable edge devices at the offices or sites to be configured with zero touch provisioning. Another huge advantage that SD-WAN offers is the possibility to create a virtual overlay of the transport network used to carry the data traffic.
How did SD-WAN start
Teldat & SD-WAN
SD-WAN is now a mature market in which Teldat has participated from the beginning. As a result Teldat has been rated by different analysts and for many years as an important player in the SD-WAN market. With all this, Teldat has obtained vital experience and specific competitive advantages.
The following bullets mention the most important points that any SD-WAN solution should include. These bullet points also detail key aspects that make Teldat’s SD-WAN solution different from the rest:
Security built on a bottom-up strategy, covering several different scenarios.
A vast product portfolio of edge routers complying with any type of network transport independence
Teldat’s Wizard / GUI is orientated towards a business purpose.
Virtualization, tackled with our specific SDE solution.
Teldat’s long history of working with legacy networks is applied into legacy networking integration within SD-WAN.
A flexible deployment strategy allowing a phased implementation of any SD-WAN solution.
Firstly, there is the device security is based on a Level 7 firewall with LAN and WAN isolation using VRFs. Then there is the overlay security which covers confidentiality, integrity and authentication which are all covered via IPSEC and segments isolating different domains and network zones. Teldat provides centralized tools for configuring end-to-end segmentation on SD-WAN solutions.
Then, an advanced security solution called be.SAFE Premium that gives another series of extra security issues for an SD-WAN solution, acting as a NGFW. Especially for systems that have direct public cloud access for branches and remote locations. This offers centralized solutions with IDS/IPS capacity, antivirus, antispam, sandboxing, etc. based on Check Point technology and fully integrated within the Teldat management portal.
Additionally, Teldat uses its in-house Network Traffic Analytics application with AI called Visualizer, for security. It offers a unique and cost-effective solution for SD-WAN security, enabling a proactive system to detect and stop security threats.
Network Transport Independence
Moreover, although network transport is totally independent, Teldat has the overlay connectivity and data center development within important carriers, which can make the migration process from MPLS to SD-WAN even smoother.
An SD-WAN system needs to be business orientated. It needs to allow the end-user easy deployment, from the initial configuration to more complex scenario configurations, minimizing the amount of supplier-specific software knowledge required. Only if this is available will an SD-WAN solution be business orientated, and this can only be achieved with a sophisticated and powerful Wizard / GUI.
Teldat does have a business orientated Wizard / GUI tool. It permits clients, end-users, managed service providers or system integrators to set up what they require. A business orientated Wizard / GUI avoids our clients dealing with knowledge barriers that increase configuration errors. Teldat’s Wizard / GUI eliminates complex protocols for basic scenarios within the SD-WAN environment. Our clients are able to easily see and understand their configurations, because our overall business orientated configuration philosophy is that every client has different needs and requirements.
- Network Wide Settings: define the basic overlay parameters and different added services, such as Visualizer server.
- Data Centers: define Data Center SD-WAN edges to concentrate VPN traffic from office or site devices.
- Access Providers: Selects different types of WAN networks and the WAN providers.
- Services: define internal and cloud traffic destinations and servers.
- User/Device Groups: Origin of the traffic, LAN groups, planned addressing deployment, that can be self-managed via the SD-WAN Controller.
- Applications: apply traffic selector rules to establish priority orders for traffic routing.
- SLA’s: define policy actions with SLA enforcement to empower the application steering with the monitored network parameters.
- Policies: apply traffic policy actions, with drop, overlay / underlay, as well as SLA enforcement that can have fallback to overlay or underlay.
- Application categories: apply one traffic policy to a set of applications.
- Branch templates: for branch SD-WAN edge to forward traffic to specific Data Center edge devices. They include configuration menus for WAN access, segments, application categories and routing policies.
Our SDDC solution offers the possibility of supporting different access or overlay networks for the data plane from the remote offices / sites to the data center. It also integrates with the Teldat SD-WAN Controller. The ability to use both Internet and MPLS, allows the user greater flexibility and an easier migration from a totally MPLS system.
The WAN is a mission critical infrastructure for any enterprise’s or organization’s connectivity. Therefore, when converting from legacy infrastructure to SD-WAN, the integration process between both types of networks is of vital importance, in order to ensure a smooth transition, without bottlenecks that can cause huge disruptions.
Teldat has a vast experience in working with legacy networks, and one of its competitive advantages is the ability to integrate both legacy and SD-WAN for clients. Firstly, because any switch from legacy to SD-WAN is not automatic. It’s a gradual process. In most cases, especially in large clients and/or complex networks, the transition from legacy to SD-WAN, needs to be carried out in different phases over time.
Another of Teldat’s competitive advantages is the ability to set up hybrid networks so that legacy networks and SD-WAN can work in the same client as a fixed solution, until the client requires to change it. Often clients want to establish certain scenarios that require such cloud connectivity for specific applications for example, to be on SD-WAN, whilst they may require specific data to continue using legacy network connectivity. It’s Teldat’s deep knowledge of legacy networks that will enable this type of solution to work correctly.
Potential SD-WAN users, analyzing the possibility of adopting an SD-WAN solution, often face two typical situations, which dissuade them from deploying SD-WAN and consequently avoiding them to realize the benefits of such solutions. The first blocking scenario occurs when the Customer is not given an integration solution that adapts to their requirements; the second negative scenario occurs when the Customer is obliged by the supplier or service provider, to take on board in one shot the full SD-WAN solution. However, Teldat solves all these issues, totally opening up SD-WAN solution to all types of companies and organizations.
Teldat is virtually the only SD-WAN developer that offers the ability to take SD-WAN on, not only with advanced integration possibilities, but also with an SD-WAN solution totally geared towards flexible deployment. Teldat’s SD-WAN can be applied gradually with a phased implementation strategy.
Firstly, our SD-WAN BASE module, which is the backbone of Teldat’s SD-WAN solution. It allows the perfect, yet simple integration of the network devices at site level and the ability to manage the entire network in a standard and automated format.
Secondly, Teldat’s SD-WAN CONTROLLER module, the heart of the Teldat SD-WAN solution, enables one click device configuration deployment and with its Level 7 application recognition, Teldat’s Controller module prioritizes network traffic.
Additionally, Teldat’s VISUALIZER tool, can be deployed on SD-WAN solutions to offer a fast, efficient, in-depth monitoring and diagnosis of networks.
