What is MPLS?

Multi Protocol Label Switching (MPLS) is a layer 2 communication switching protocol that relies on compact switching labels to relay payload to the next hop as opposed to the layer 3 IP addressing that used in the common IP routing protocol. MPLS provides quicker look ups and therefore has lower latency.

MPLS - Multi Protocol Label Switching network

MPLS circuits historically have been used to connect branch offices to each other to facilitate the communication between the branches. For IP traffic destined to/from public Internet, the branch office required to connect to the service provider core via the layer 2, as MPLS does not have layer 3 routing ability. Once the packets are received to the service provider core, the MPLS labels are stripped and packets are dropped into the layer 3 network to be routed to the public Internet.

Shortcomings with MPLS

Internet traffic cannot be routed locally

Since MPLS transport doesn’t have layer 3 routing capabilities, the packets in and out of the branch offices need to go through the MPLS gateway at the service provider core. This means any type of traffic, including web surfing or traffic destined to public cloud will go through the expensive MPLS circuits just to connect to the Internet.

MPLS cost is high

MPLS transport has been expensive. Especially when compared to broadband Internet access lines such as DSL, Cable, and fiber, for per bit delivered, the cost of MPLS can unnecessarily consume a significant portion of the IT budget. IT managers are usually presented with expensive MPLS upgrade options that are not practical.

Single point of failure

MPLS, even though advertised by carriers to have higher up-time, they still go down when the carrier has a technical problem. Since MPLS primarily based on a single service provider and single transport, it creates a single point of failure

Long lead times and limited bandwidth

MPLS upgrades for higher bandwidth may not be possible in some cases, or otherwise are cost prohibitive. The lead times for MPLS installation and upgrades can be impractically long.


Agile traffic management

Mushroom’s SD-WAN enables easy QoS and traffic management so that Internet traffic can be routed locally without consuming the point-to-point tunnel from branch office to the data-center or between branch offices. This significantly reduces the traffic that needs to go through the tunnels between branches.

Boosted reliability with high 9s uptime

With the availability of various carriers and service providers for the connectivity including MPLS, DSL, Cable, Fiber or even 3G, 4G, LTE wireless, office connectivity is no longer tied to a single point of failure. With Mushroom’s VNF tunnels, even on-going sessions will be kept alive during blackout or brownouts on any of the Internet connections.

Cost effective as MPLS augmentation

Since cost effective broadband Internet lines can be brought together with Mushroom’s SD-WAN, the overlay IP connectivity will have boosted QoS metrics. This enables a very effective MPLS alternative to either augment existing MPLS or completely replace MPLS circuits.

Rapid rollout and installation

Installation and rollout of new locations can be completed within minutes, with drop shipping preconfigured units to the branch that is being brought up. The installation and lead times are orders of magnitude faster compared to MPLS.

Why Mushroom's SD-WAN?

Application centric approach

Mushroom’s SD-WAN technology has an application centric technology at the core. This means flows can be identified and treated via the overlay tunnels that are designed to optimize that specific application. Since application needs for QoS (Quality of Service) differs from throughput, packet-loss, latency, jitter and many others including historic performance, highly advanced tunnels are leveraged to optimize the flows.

Proven track record and experience

Mushroom’s SD-WAN solutions have been deployed world-wide with the widest and largest portfolio of clients and use-cases in the sector, from large enterprises, to service providers for branch office connectivity to broadcasters, to trains for optimized connectivity over 3G, 4G, LTE wireless. Mushroom’s solutions embed technologies that are perfected over the years with unique know-how and in-the-field experience that is unique in the industry.

Automation at every level

One of the added values of SD-WAN architectures is based on automating the configuration and management of the end-points. However, being able to automate problem mitigation via setting the WAN networks on autopilot is unique to Mushroom’s SD-WAN, whereby advanced tunnels can automatically detect network conditions that can negatively effect a specific flow type and accordingly implement measures to router around the network problem in real-time without dropping on-going sessions.

VNF Design Studio

Mushroom’s SD-WAN solutions come with built-in library of VNFs. However, for service providers and enterprises that would like to customize their overlay networks, Mushroom’s VNF Design Studio offers a drag-and-drop based UI to build or modify tunnels with ease. This shrinks the new service development and rollout cycle by orders of magnitude.
