Glossary and FAQ

MPLS (Multiprotocol Label Switching)
Multiprotocol Label Switching (MPLS) is a network protocol for speeding up and shaping wide area network (WAN) traffic flows.

On-Premise SD-WAN
On-premise SD-WAN is one of the architecture types in which the SD-WAN is setup with a local box “on-premise” or at the business’s location.

SD-WAN Traffic Shaping
SD-WAN traffic shaping is a means of manipulating and prioritizing network traffic.

Fast Traffic Switching
Fast traffic switching is the change between different voice sessions when a disruptive event occurs.

Cloud-Enabled SD-WAN
Cloud-Enabled SD-WAN is an SD-WAN architecture offering on-site equipment that connects to a cloud gateway (or virtual gateway).

Link-State Monitoring
Link-state monitoring is the process in which multiple traffic paths are constantly monitored simultaneously to assess both connectivity and traffic performance and ensure traffic is passed over the most optimal path at all times.

Dynamic Path Selection
Dynamic path selection is a core component of SD-WAN working in conjunction with link-state monitoring.

Cloud-Enabled Plus Backbone SD-WAN
Cloud-Enabled Plus Backbone SD-WAN is an expansion of the traditional SD-WAN architecture where connectivity and strength of connection are reinforced by the SD-WAN providers network backbone.

SD-WAN Security
SD-WAN Security is the process of inspecting incoming and outgoing traffic (including site-to-site traffic) in an effort to maintain the security and restriction of access to files from unauthorized access, much like standard network security.

Edge Computing
Edge Computing is a tight network of microdata centers that process or store critical data locally and push all received data to a central data center or cloud storage repository, in a footprint of less than 100 square feet.

Network Security
Network Security is the protection and/or restriction of access to files and directories within a computer network against unauthorized access, system and file changes, and hacking.

SD-WAN Zero Touch Provisioning
SD-WAN Zero Touch Provisioning (ZTP) is a key benefit of SD-WAN allowing systems to be provisioned and configured automatically, significantly reducing cost and manual overhead.

SD-WAN Controller
The SD-WAN Controller is a core component of any SD-WAN solution and is vital in the implementation of new capabilities, working to provide basic and advanced features.

SD-WAN Regional Hub
An SD-WAN Regional Hub is a network model bringing the best of the hub and spoke and the full mesh architecture to improve performance as well as security, with simplified provisioning alongside extended connectivity.

SD-WAN Full Mesh
SD-WAN Full Mesh is a network modeled around fully integrated communication allowing for traffic to pass between all branches in the network.

SD-WAN Hub and Spoke
SD-WAN Hub and Spoke is the traditional approach to creating a Wide Area Network (WAN) over a virtual private network.

SD-WAN Drivers
An SD-WAN Driver is the main reason an organization should, or is interested in, adoption of SD-WAN.

SD-WAN Architecture
SD-WAN Architecture is the high-level structure of the software and hardware system that make up the SD-WAN and how it’s deployed.

SD-WAN Market
The SD-WAN Market is defined under an umbrella which includes the technology and software used to drive service deployment, vendors and suppliers, carriers, and consumers.

SD-WAN Vendors
SD-Wan Vendors are any supplier or vendor offering access to superior SD-WAN infrastructure, typically via subscription model to eliminate costly investment associated with upgrading legacy networks.

SMART Technology
SMART stands for “Self-Monitoring Analysis and Reporting Technology.”

Router Protocols
A Routing Protocol specifies how routers communicate with each other.

IoT Protocols
Internet of Things (IoT) Protocols go beyond the connectivity of traditional equipment such as desktop computers, laptops, tablets, printers, and phones to include embedded technologies such as security systems, thermostats, and home lighting systems – all via the Internet.

Network Architecture
The term “Network Architecture” describes the complete framework of an organization’s computer network.

Cloud Infrastructure
Cloud Infrastructure refers to the hardware and software components that are required to support the computing needs of a cloud computing model.

In the context of WANs, a Brownout is an episode of unknown duration where congestion-based packet loss and increases in latency and jitter cause poor application performance.

Cloud Technology
Cloud computing is the storing and accessing of data and programs over the Internet instead of a computer’s local hard drive.

WAN (Wide Area Network)
A Wide Area Network (WAN) is a network that spans over a large geographical area.

Network Monitoring
Network Monitoring is the use of a system that monitors the network for failing or faulty components on an ongoing basis.

Failsafe SD-WAN
A Failsafe SD-WAN is an SD-WAN Solution that delivers both MPLS-class high availability and high QoE (Quality of Experience) predictable application performance for both TCP-based apps and real-time apps like VoIP and videoconferencing, whether built on a hybrid MPLS plus Internet WAN fabric, or a WAN made up only of Internet connections.

Failsafe SD-WAN Technologies
Failsafe SD-WAN Technologies are a set of software capabilities of an SD-WAN offering that are able to deliver predictable application performance over a multi-link WAN fabric that includes Internet connections.

Failsafe Network / Failsafe WAN
A Failsafe Network is a network that delivers both high availability and reliable, predictable application performance (a.k.a. Quality of Experience, or QoE).

Application Performance Monitoring
Application Performance Monitoring focuses on making sure software programs perform as expected.

Network Controller
A Network Controller is a highly available and scalable server role.

Hybrid WAN
A Hybrid WAN (wide area network) connects two geographically separate sites, by combining two or more network links with dynamically engineered traffic.

Network Edge Router
A Network Edge Router is a specialized piece of equipment located at the edge of a network.

Software-Defined WAN
A Software-Defined wide area network (SD-WAN) is an application of Software-Defined networking (SDN).

WAN Aggregation
Wide Area Network (WAN) Aggregation, also referred to as “link load balancing,” focuses on the Internet-facing connections of a business.

WAN Optimization
Wide Area Network (WAN) Optimization, also referred to as WAN acceleration, is a category of techniques used to make the network and applications perform faster and more reliably across the WAN.

WAN Optimization technology
Wide Area Network (WAN) Optimization technology uses a combination of protocol optimizations, using data deduping and compression, data caching and congestion control technologies.

WAN Virtualization
Wide Area Network (WAN) virtualization combines two or more network connections of any type.
