Create WANs made up of multiple connections, from multiple service providers, in multiple geographies – and apply global rules, alerts, and features easily.

Our system was designed to give you remote access to each device in your network and to make truck-rolls a thing of the past.  By abstacting the control plane from the data plane, we have a unique ability to make oft-needed changes to customer configurations remotely. Deploy new sites, change policies, add WAN links – all in seconds.

Network Services Group can now support global customers easily with our technology.

The Nodes

The system is comprised of just four node types. Some allow for creating a more meshed topology, others perform certain required functions – like Bonding, Fast-Failover, Traffic Encryption, and Quality of Service.


This device sits at each client site. It sends and receives traffic over multiple circuits.

Aggregation Server(s)

A core server that combines a customer’s outgoing traffic from each circuit and splits incoming traffic down each circuit.

PWAN Router(s)

An optional core device that allows geographically separated sites to securely route traffic to  each other as if each site was connected to the same router.

Management Server

The web interface where a collection of circuits, connected IPs, CPE NAT IPs, routes, and other settings are configured and monitored.

How it works

Traffic leaving your site

The Bonder receives and disassembles the traffic from a LAN node. It then distributes the individual packets across the WAN connections based on rules and policies that have been set in the Management Server. The traffic packets are re-ordered at the Aggregation Server before being sent to the destination host.

Traffic going to your site

The Aggregation Server broadcasts your customers’ IP address(es) and receives all of its traffic. It then disassembles the traffic into packets and sprays those packets across the multiple WAN links – applying customer/ application/class-specific prioritization, cryptography, and/or routing rules. At the customer’s site, the Bonder receives the packets and re-orders them before sending them into the LAN and to the recipient node.

Technical Details

The technology uses a packet-level distribution algorithm to effectively control WAN paths. The service encapsulates multiple WAN connections into a proprietary, over-the-top protocol  that routes traffic over the Internet.

Decisions about traffic shaping, prioritization and balancing are made through a Cloud-based management server that monitors the health of your WAN connections – the control plane. This device then sends traffic-handling information to each of the devices in the network, so that each node knows what it needs to do to ensure the customer experience is optimized.
