Broadband Bonding Service


Broadband bonding service

Broadband Bonding as a Managed Service

Mushroom Networks customer premises equipment (CPE) devices like Truffle and Portabella can bond HTTPS downlink traffic without requiring a peering device or service. The optional Broadband Bonding Service (BBS) provides application-centric overlay tunnels that peer the CPE to Mushroom Relay Servers in the cloud. This enables packet-level bonding tunnels for any protocol or application, including video, VoIP, uploads, chatty applications, and more. With BBS, even single internet sessions can be striped across available links, unlocking the aggregate bandwidth.

Self-hosted Broadband Bonding Service – Virtual Leased Line

Self-Hosted Broadband Bonding (Virtual Leased Line)

The Virtual Leased Line (VLL) solution provides secure, fast, and reliable office-to-office VPN connectivity between multiple locations. It creates an IP tunnel that utilizes the bonded internet access lines available at each endpoint. VLL enables a bonded VPN internet pipe between offices or between an office and its data center. This is accomplished via Truffle appliances at each site.

VLL can bond any internet access type from any provider, including fiber, DSL, cable, T1, E1, DIA, MPLS, etc., without ISP coordination. VLL tunnels support star and mesh VPN topologies, with optional encryption or transparent operation with existing VPNs for VPN bonding.

Virtual Leased Lines offer quick return on investment (ROI) and lower operating expenses when used with or as an alternative to MPLS. Cost-effective bandwidth is supplied through cheaper broadband lines, while Mushroom Networks’ VLL manages quality of service. The payback period is often just weeks. Application notes and ROI analysis whitepapers are available here.


Downlink and Uplink Bonding

When used with the Broadband Bonding Service (BBS) or peered to another Truffle/Portabella device, these load-balancing routers can bond internet access lines for all types of traffic, including encrypted VPN traffic, providing aggregated downlink and uplink speed and capacity.

Application Armor with Session Keep Alive

Mushroom Networks devices continuously monitor network conditions and intelligently react in real-time to mitigate performance degradation caused by WAN issues. Managed parameters include packet loss, latency, jitter, cross-traffic, buffer bloat, MTU problems, black holes, and more. If any WAN link at a branch office experiences issues like packet loss or latency spikes, the bonding tunnel maintains ongoing IP sessions without performance loss by shielding the negative effects and re-routing traffic.

Networks on Autopilot for High Reliability

In case of internet access line issues, Truffle/Portabella can keep active sessions alive by making real-time per-packet routing decisions, even for in-progress sessions. Automatic failover also protects against one or more WAN link failures.

Advanced QoS for Application Optimization

The application-centric bonding tunnels can optimize traffic flows for various applications. For example, they can route VoIP/SIP call packets around network issues to maintain optimal call quality (MOS score).

Elastic Static IP

Static IP addresses from the cloud or your data center can be mapped onto the branch office Truffle, providing a stable IP for services relying on it (VPNs, IP-PBX, remote access) even during WAN outages, as long as one WAN link remains active.



Truffle and Portabella devices can peer with a Mushroom Relay device through the Broadband Bonding Service (BBS) or another physical/virtual Truffle appliance hosted in the data center. Between the two endpoints, a VPN-like overlay tunnel is created to orchestrate the multi-WAN paths. For connectivity between multiple offices, star or mesh topologies are supported.

Application-Optimized Algorithms

The bonding tunnels between Mushroom endpoints implement advanced networking algorithms to optimize traffic flows. Various application-centric overlay tunnels are optimized for VoIP, video, unified communications, chatty applications, cloud services, file transfers, and other application types.

Real-Time Measurements

The algorithms powering the Virtual Leased Line (VLL) tunnels rely on the system’s ability to measure real-time parameters like packet loss, latency, jitter, and recent network history metrics using in-band and out-of-band techniques.

Third-Party Monitoring Support

Third-party monitoring solutions are supported via SNMP, Syslog, Netflow, and other standard APIs.

Software-Defined WAN (SD-WAN) Architecture

Mushroom Networks solutions are built on an award-winning, industry-leading SD-WAN architecture. The software-defined approach enables easy development, deployment, and management of bonding tunnels and customer premises equipment (CPE) devices. A single-pane-of-glass dashboard provides visibility and remote access to CPEs from a cloud-based portal, supporting zero-touch preconfiguration and rapid deployment.

Implementation Options

The relay side of the peering tunnel can be implemented using a Truffle physical appliance, a virtual Truffle V running on VMware/Xen hypervisors, or the Mushroom Networks-hosted BBS service in Mushroom data centers or on AWS EC2.

Scalable Platform

Mushroom Networks’ vertically and horizontally scalable platform supports clients from single-office small businesses to multi-tenant service provider rollouts with thousands of customers.

Clients include:


Mushroom Networks devices have two modes – standalone mode bonds only HTTP downlink traffic while load balancing other traffic types. For packet-level bonding across all traffic types, including live video streaming, a peering node (our Cloud Relay Service or your own Relay Server) is needed to stitch packets back together.

Depending on your traffic type, various tunnels are available:

  • Video Armor tunnel for live video streaming applications
  • VoIP Armor tunnel for real-time applications
  • App Armor tunnels for generic internet applications

These tunnels work alongside the flagship broadband bonding tunnel and are compatible across Mushroom Networks devices.
