A field reference for engineers and integrators, from the antenna to the cloud
Presented by West Networks Peplink University · Complete edition
The companion volume to Networking Fundamentals. That paper covered the vendor-neutral building blocks, addressing, switching, routing, segmentation, and security, and closed each topic with a short note on how it changes in an SD-WAN world. This paper picks up exactly where that note left off. Here the subject is Peplink itself: what SpeedFusion actually does, how each of its features works and what it costs, how InControl and Zero Touch manage a fleet, and how the classic protocols, Layer 2, Layer 3, OSPF, and BGP, behave once they run on Peplink gear. Each topic follows the same pattern: what it is, how it works on Peplink, why it matters, and a short real-world note. Field questions from our own engineers are answered inline where they fit, and collected again in the FAQ at the end.
This complete edition was built by reviewing all forty Peplink University chapters against the fundamentals course and filling every gap, so a new engineer can learn the whole platform from one document.
The Peplink Stack
Before any single feature makes sense, you need the shape of the whole system in your head. Peplink is not one product; it is three layers that work together.
Read →SpeedFusion & Dynamic Weighted Bonding
SpeedFusion is the protocol that bonds multiple WAN connections into a single, resilient virtual link. The thirty-second version: most VPN tunnels fail one of two ways…
Read →Bonding, Hot Failover & Load Balancing
Peplink can do three fundamentally different things with multiple WANs, and conflating them causes most early design mistakes. They are not interchangeable, and each has…
Read →WAN Smoothing, FEC & Sub-Tunnels
WAN Smoothing creates a single, jitter-free data stream by duplicating packets across multiple WAN links and using whichever copy arrives first; the later copies are…
Read →Boost, TCP & Sizing the Overhead
SpeedFusion Boost is acceleration for an individual link, particularly the high-latency, high-loss paths like 5G and Starlink. It is the one part of the SpeedFusion…
Read →Outbound Policy, Layer 2/3 & Routing
Outbound policy is how a Peplink router decides which WAN a given flow should use, the traffic-shaping and steering layer that sits alongside SpeedFusion. Even before…
Read →FusionHub, SpeedFusion Connect & InControl
FusionHub is Peplink's virtual SpeedFusion appliance, SpeedFusion in software, running on a VM instead of in a hardware router. It exists to be the other end of the…
Read →Topologies, Ports & Field Playbooks
How the SpeedFusion endpoints connect to each other, the topology, shapes the whole deployment. There are three standard patterns, and most real networks are a…
Read →RF: Cellular, Antenna, Satellite, Wi-Fi & GPS
For most Peplink deployments the primary WAN is cellular, so an engineer has to understand the mobile link itself, not just the bonding on top of it. A cellular…
Read →Management, Diagnostics, Edge & Capacity
Managing the fleet is one thing (InControl, Part Seventeen); reaching the gear behind a router, or recovering a site whose primary link is down, is another. Peplink's…
Read →Product Line, Case Study & Setup
A fundamentals course has to include mapping a requirement to the right hardware. The Peplink line is broad but organized, and a handful of families cover almost every…
Read →Security: Locking Down the Bonded Network
Per-link encryption, FIPS & TAA, hardened admin access, the four-domain firewall, identity-driven segmentation, and SIEM-ready logging — the defensibility layer of the platform.
