SD-WAN Technical Overview
ALL SITES, ONE TOOL
An online portal allows you to see and manage everything – empowering you to make any required changes in seconds.
Create WANs made up of multiple connections, from multiple service providers, in multiple geographies – and apply global rules, alerts, and features easily.
A networking software that combines multiple IP connections to create a single, smart pipe.
Technical Details
The technology uses a packet-level distribution algorithm to effectively control WAN paths. The service encapsulates multiple WAN connections into a proprietary, over-the-top protocol that routes traffic over the Internet. Decisions about traffic shaping, prioritization and balancing are made through a Cloud-based management server that monitors the health of your WAN connections – the control plane. This device then sends traffic-handling information to each of the devices in the network, so that each node knows what it needs to do to ensure the customer experience is optimized.
How it works
Traffic leaving customer’s site
The CPE (Bonder) receives and disassembles the traffic from a LAN node. It then distributes the individual packets across the WAN connections based on rules and policies that have been set in the Management Server. The traffic packets are re-ordered at the Aggregation Server before being sent to the destination host.
Traffic going to customer’s site
The Aggregation Server broadcasts customers’ IP address(es) and receives all of its traffic. It then disassembles the traffic into packets and sprays those packets across the multiple WAN links – applying customer/ application/class-specific prioritization, cryptography, and/or routing rules. At the customer’s site, the CPE receives the packets and re-orders them before sending them into the LAN and to the recipient node.
Enterprise Solution
MPLS ADD-ON
Limitations of Traditional MPLS
Enterprises have typically connected their branch offices through a private Multi-Protocol Label Switching (MPLS) data service. While reliable, traditional MPLS based Wide Area Network (WAN) have two clear limitations:
(1) Cost prohibitive: up to 10X the price of typical Internet connection
(2) Lack of general availability: coverage issues, local loop complexity We’ve found that roughly 8% of MPLS based WAN branches aren’t actually MPLS at all – they’re over the public Internet because of reach or high cost. This means almost 1 in every 10 MPLS branches doesn’t adhere to corporate WAN policies (security, application assurance, redundancy, and etc). Enterprises that can, spend more than twice as much to incorporate remote sites, compared to urban sites.
Enterprise Class WAN, Leverage the Internet
Today, savvy network administrators are looking for creative ways to get all the benefits of MPLS, but control costs and maintain uniformity across the WAN. To satisfy these requirements we offer a solution to create a consistent network platform that enhances communication and coordination to include the troublesome 8%. Our cutting edge technology combines multiple low-cost Internet connections into a single, faster and more reliable connection onto which we layer a centralized firewall, end-to-end Quality of Service (QoS), and WAN monitoring management.
Prepare For the Future
Network technology enables people to communicate to one another. It allows devices to speak to each other in the form data transmission. And, with the average enterprise projected to manage 50 times more data by 2020, the infrastructure supporting the flow of traffic needs to be simple, scalable, and secure. MPLS is one way to ensure real-time application quality on increasingly congested networks, but for a complete solution you need to supplement MPLS. We help your branches that are missing from your MPLS WAN prepare for the future with our MPLS Add-On solution.

SD-WAN
Private Wide Area Network
Multi-site businesses are faced with the challenge of managing traffic routes from site to site quickly and securely using some form of Private Wide Area Network (PWAN). The four most critical factors to consider are:
- Security: Recent massive data breaches at many large, multi-site enterprises (impacting tens of millions of people) highlight the importance of having safeguards in place to protect your valuable digital information and to meet industry compliance requirements.
- Cost Control: Organizations spend almost five times as much to incorporate remote sites compared to urban sites due to logistical complexity. The significant over-spend in both CapEx and recurring monthly charges needs to be contained.
- Reliability: Network failures are inevitable; often caused by way of accidentally cut lines, weather and environment issues, hacking, or other unforeseen issues beyond the control of the service provider. Businesses need a reliable failover system that can respond quickly and gracefully.
- Availability: Almost 1 in every 10 MPLS branches transmit over the public Internet because of lack of general availability. The ability to easily add users and nodes regardless of geography is a must to future-proof your WAN and meet ever-increasing expectations.
