Bigleaf SD-WAN vs Nokia Nuage Networks SD-WAN

Bigleaf SD-WAN is a web-based hybrid service for improving internet performance for business-critical cloud applications across business locations. Its Cloud Connect uses dynamic quality-of-service classification to prioritize traffic in real time, while application-aware routing sends voice and video toward circuits with lower latency, jitter, and packet loss. High-throughput tasks use circuits with more available bandwidth. The service measures latency, jitter, packet loss, and capacity 10 times per second in both directions, and can shift traffic between ISP circuits while keeping Bigleaf-issued IP addresses unchanged. A preconfigured router installs outside an existing firewall, supports up to four broadband circuits, and is described as having a 90-second installation. Wired and wireless circuits are supported, including fiber, cable, LEO satellite, and 5G LTE. The dashboard shows cross-site performance, alerts, and insights. Pricing is on request, with monthly billing and 12-, 24-, or 36-month agreements available.

Nokia Nuage Networks SD-WAN, also called VNS, links branch locations with private data centers, public clouds, provider-managed VPNs, and SaaS services. A central policy repository applies business and application requirements to WAN links and routes, with the aim of meeting performance, cost, security, and policy criteria. Listed transports include IP/MPLS, internet, and LTE/5G. Nokia says automated site or VPN setup can take a few minutes rather than several weeks. The SD-WAN 2.0 architecture adds application-level visibility and control across branches, private data centers, and public clouds, with traffic details such as source, destination, type, and rates. It can orchestrate third-party virtual network functions on uCPE and chain functions in data centers or clouds. Security capabilities include web filtering, application control, segmentation, stateful Layer 3–4 security, and intrusion detection and prevention; some features require add-on licenses. It supports Linux, web, and self-hosted environments. Pricing is on request.
