The marriage of software-defined networking (SDN) benefits to WAN technology yields the software-defined wide area network (SD-WAN), which allows consumer-grade links (or links without assured performance) to be leveraged for business-class services. Through the use of common VPN capabilities and the separation of data and control planes within SDN, software-managed connections can be established and managed between multiple sites over any number of link types (e.g., fixed circuit, DSL, cable, mobile, MPLS, and so on) without the operational challenges of having to manage different links.
SD-WANs easily establish links, manage traffic over links according to application or service requirements (e.g., VoIP vs. Facebook), and enforce policy control capabilities (e.g., limit web-based traffic to 50% of a given link), and they are simple to manage. SD-WAN options are part router, part WAN optimization, and part firewall. In addition, some SD-WAN offerings provide robust security, which makes for a compelling alternative to the multiple-appliance approach that is often required at remote locations.
NSS Labs' Software-Defined Wide Area Network (SD-WAN) Group Test evaluates market-leading SD-WAN products on total cost of ownership (TCO) and Quality of Experience (QoE) for the VoIP quality and video quality of tested products. The SD-WAN Group Test provides individual Test Reports and Comparative Reports that enable enterprises to make informed decisions to evolve and rationalize their cyber risk programs.
Individual Test Reports
Test Reports provide detailed analysis for each product tested. Data from these reports is used in the NSS Labs Comparative Reports.
Test Reports enable enterprise security teams to understand the impact of features and limitations across different products. These reports are used to shortlist products for further evaluation and proof-of concept testing.
