Glossary // SD-WAN

What is SD-WAN?

SD-WAN simplifies WAN management and operations by separating network hardware from its controller. This concept is analogous to the Software Defined Networking paradigm that implements virtualization technology to improve Data Center management and operations.

Importance of SD-WAN

1. Customers and providers can find out in detail what application passes a WAN link and how much bandwidth is used for the application, making it easier for evaluations to optimize application performance.
2. Customers get the convenience of expanding WAN connectivity to new branches of the company efficiently without depending on one provider.
3. Customers and providers have the convenience to increase or decrease bandwidth (flexible bandwidth) according to their current needs.
4. SD-WAN reduces the complexity in managing various types of WAN connectivity devices (routers, firewalls, bandwidth management, load balancers, encryptor, etc)
5. SD-WAN allows users to manage all WAN connectivity devices in a centralized dashboard.

SD-WAN Architecture Key Benefits

• Greater agility - allows the introduction of global changes in all locations from a centralized platform.
• Cost reduction - centralized deployment eliminates the need for local configurations.
• All applications can integrate into the network.
• Scalability - Simplification and faster in policy changes, updates of software and new branch deployments without putting benefits at risk.
• Technical assistance - Service of attention global 24/7 based on ITIL standards.
• Easy insertion of complementary services - other services such as Security, UCC, Cloud Services or other virtual network functions can be introduced and chained easily.
