Broadband Bonding Service

Broadband Bonding as Managed Service

Mushroom Networks CPE devices (such as Truffle and Portabella) have the built-in ability to bond HTTPS downlink traffic without requiring a peering device or service. The optional Broadband Bonding Service (BBS) are the application centric overlay tunnels that are peers the Mushroom Networks CPE to the Mushroom Relay Servers in the cloud. This enables tunnels with packet granularity bonding for any protocol or application including video, VoIP, uploads, chatty applications and so on. With BBS, even a single internet session can be striped over the available links unlocking the aggregate speed of the connections.

Self-hosted Broadband Bonding Service – Virtual Leased Line

Self-hosted Broadband Bonding (Virtual Leased Line)

The Virtual Leased Line (VLL) provides secure, fast and reliable office-to-office VPN connectivity between multiple locations by creating an IP tunnel that uses the bonded Internet access lines available on each side. VLL can enable a bonded VPN Internet pipe between two office locations or between the office and its Internet data center. This is accomplished via Truffle appliances at each endpoint. VLL can bond any type of Internet access line from any service provider including fiber, DSL, cable, T1, E1, DIA, MPLS, etc., without requiring any coordination with the ISPs. VLL tunnels support star and mesh topologies for office-to-office VPNs. VLL supports encryption or can work transparently with your existing VPN to accomplish VPN bonding.

Virtual Leased Lines provide a quick Return on Investment (ROI) and lower operating expenses when used in conjunction with MPLS or as an alternative to MPLS. Cost-effective bandwidth is supplied through cheaper broadband lines and Quality of Service is managed by Mushroom Networks’ VLL. The payback period on the investment is often measured in weeks. You can download application notes and ROI analysis white papers here.


Downlink and Uplink Bonding

When Truffle or Portabella load-balancing routers are used with BBS (or peered to another Truffle device), they have the ability to bond Internet access lines for all types of traffic, including encrypted traffic such as VPN, for aggregated downlink and uplink speed and capacity.

Application Armor with Session Keep Alive

Mushroom Networks devices monitor network conditions and intelligently reacts in real time to mitigate any performance degradation caused by WAN network problems. Managed parameters and network problems include packet loss, latency, jitter, cross-traffic, buffer management, MTU problems, black holes, as well as others. In case of packet loss, spike in latency, or any other degradation on any of the WAN links at the branch office, the VLL tunnel maintains the ongoing IP sessions without loss of performance. VLL accomplishes this by shielding the negative effects of dropped WAN links, lost packets, or high latency on any of the WAN links.

Networks on Autopilot for High 9s Reliability

In case of Internet access line network problems, Truffle (Portabella) has the ability to keep the ongoing sessions alive by making real-time per-packet routing path decisions, even for the sessions in progress. Additionally, automatic fail over protects against failures of one or more WAN links.

Advanced QoS Algorithms

Application-centric bonding tunnels have the ability to optimize the flows for various applications. As an example, the bonding tunnel has the ability to route packets around networking problems for on-going VoIP/SIP phone calls to keep the MOS score optimized.

Elastic Static IP

Static IP addresses in the cloud (or from your data center) can be mapped onto the branch office Truffle. This means that static IP is available for services that rely on stable IP addressing (such as VPNs, IP-PBX, remote inbound access etc.), even during WAN outages, as long as at least one of the WAN links is up.



Truffle (Portabella) devices have the ability to peer with a Mushroom Relay device either through the BBS, or another physical or virtual Truffle appliance hosted in the data center. Between the two endpoints, a VPN-like overlay tunnel is created that can orchestrate the multi-WAN paths. For connectivity between larger number of offices, star or mesh topologies are supported.


The bonding tunnels between the Mushroom endpoints has the ability to implement advanced networking algorithms to optimize the traffic flow that goes through it. Various application-centric overlay tunnels are optimized for various applications such as VoIP, video, UC, chatty applications, cloud-delivered services, file transfers and other application classes.


The algorithms that power the Virtual Leased Line tunnels (VLL) rely on the system’s ability to measure various real-time parameters such as packet loss, latency, and jitter as well as recent network history metrics the system measures. The measurements are facilitated via both in-band and out-of-band techniques.


Mushroom Networks solutions are based on the industry leading and award-winning Software-Defined WAN (SD-WAN) architecture. The software defined approach enables easy development and deployment bonding tunnels as well as simple and easy management and monitoring of the CPE devices. The single pane of glass dashboard provides visibility and remote access to the CPE units from cloud-based Portal. Devices can be preconfigured and drop-shipped to the location with zero-touch configuration, ensuring rapid and successful deployment.

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


The Relay side of the peering tunnel can be implemented either with a Truffle physical appliance, a Truffle V (a virtual appliance running on a VMWare Hypervisor or Xen Hypervisor) or via the Mushroom Networks-hosted BBS service on Mushroom Networks’ data centers or colocated at AWS (Amazon Web Services) EC2.


Clients both big and small, from a single office small business all the way to a service provider roll out with multi-tenancy support for thousands of customers, are supported in Mushroom Networks’ vertically and horizontally scalable platform.

Our units have two operating modes, namely, the standalone mode and the peered mode. In standalone mode, only http downlink traffic will be bonded and all other types of traffic will be load-balanced. For packet level aggregation granularity, including bonding for all types of traffic and streaming live video, a peering node (either our Cloud Relay Service, or your own Mushroom Networks Relay Server) is needed in order to stitch the packets back together during the bonding process.

Depending on your traffic type various types of tunnels are available. For live video streaming applications, our Video Armor tunnel, for real-time applications our VoIP Armor tunnel, for generic Internet applications our App Armor tunnels can be used alongside our flagship broadband bonding tunnel.
