Technology · Peplink SpeedFusion

True WAN bonding.
Refined for two decades.

Most "bonding" claimed by competitors is just load balancing in disguise. SpeedFusion™ isn't. It's packet-level WAN bonding — combining fibre, 5G, LTE, and LEO satellite into one resilient pipe where every link contributes bandwidth and any single link can drop without sessions noticing.

Peplink SpeedFusion — bonded waveforms
Cut through the confusion

Load balancing isn't bonding.

Vendors blur these terms. Buyers get burned. Here's the actual technical difference.

Load balancing

Sessions split across links

Different sessions get routed across different WAN links. Each individual flow still rides only one link.

  • Aggregate throughput across users, yes
  • Single-flow speed = single link only
  • One link drops, in-flight sessions die
  • Marketed as "bonding" by some vendors. It isn't.
SpeedFusion

True packet-level bonding

A single connection is split across every available link at packet level, then reassembled in order at the other end.

  • Single-flow speed = sum of all links
  • Link drops mid-flow = no session interruption
  • Forward Error Correction for lossy links
  • Patented. 20 years in production. The actual thing.
How it works

Packets out. Packets back. In order.

SpeedFusion creates a tunnel between a Peplink device and a SpeedFusion endpoint (router, cloud node, or hub). Packets within that tunnel are split across every available WAN link, transmitted in parallel, and reassembled on arrival. The application sees one connection; underneath, every link is contributing.

Read it left to right. (1) Apps send their traffic to the Peplink router. (2) The router splits each session's packets. (3) Those packets ride across every WAN link in parallel. (4) The SpeedFusion endpoint reassembles them in order. (5) One bonded stream — at the combined bandwidth of every link — heads out to the internet.
What SpeedFusion actually does

Three technologies. One unbreakable pipe.

SpeedFusion isn't a single feature. It's three bonding behaviours working together — combining the bandwidth, eliminating the gaps, and surviving the failures.

Bandwidth Bonding

Maximum bandwidth, fully utilised. Aggregates every available connection into a single high-capacity tunnel. Data is distributed at the packet level, so any single session can use the total combined bandwidth of all links — not just one of them.

Smoothing

Seamless performance, no jitter. Intelligent algorithms fill connectivity gaps by sending redundant packets through multiple channels simultaneously. When live video stutters elsewhere because of packet loss, SpeedFusion delivers it cleanly. Trades a little bandwidth for connection resiliency.

Hot Failover

Uninterrupted connectivity, zero downtime. Unlike traditional failover that waits for a link to die before reacting, Hot Failover transfers traffic to healthy links the moment quality degrades. Active sessions never know.

What SpeedFusion delivers

What changes on day one.

×N

N times the bandwidth per connection

Where N is the number of WAN links you bond. Bandwidth is now a sum, not a maximum.

<1s

Sub-second failover, mid-session

A link dropping is invisible to your application. The user, the call, the stream — none of them notice.

Any

Any link type, mixed freely

Bond fibre with LTE with 5G with Starlink with satellite — different technologies, different latencies, different operators. Mixed in one pipe.

+0

Zero application changes

Your applications, your VoIP, your video, your VPN — none of them know SpeedFusion exists. They just suddenly work better.

Hardware that runs SpeedFusion

Across the entire Peplink line.

SpeedFusion runs on every Peplink router. The choice of hardware comes from your site — number of WAN ports, throughput required, environment, form factor.
