SD WAN FAQs

SD-WAN is an acronym for Software Defined Wide Area Networking.

An SD-WAN box provides high-quality internet with a public static IP address by bonding a variety of internet sources, including fixed line, cellular SIM cards and/or satellite, creating a unified, secure internet connection.

SD-WAN is an essential solution for companies that:

1. Do not have fixed line internet available on site
2. Have unreliable internet connectivity
3. Where always-on internet is critical

SD-WAN Pro is Anvil’s newly released SD-WAN solution, which includes our state-of-the-art SD-WAN box and licensed management platform.

SD-WAN Pro includes the option to bond three types of internet connectivity, achieving download/upload speeds ranging from 100Mbps to 500Mbps.

SD-WAN can be provided with or without connectivity.

There are a number of SD-WAN solutions available depending on the outcome required.

Please see here for the full range. Please feel free to get in touch via Live Chat should you have further questions.

You can use any combination of:

• Fixed Line
• Cellular SIM cards (integrated SIM slot and/or 4G router)
• Satellite

The SD-WAN Pro box has a single internal SIM card slot, plus 4 x RJ45 ports. Our standard SD-WAN Pro package enables you to use 3 x internet connections for either bonding or failover, which can include the internal SIM card.

There are 3 licenses available as below. This speed is symmetrical upload/download, however, the speed achievable is dependent on the internet sources connected to the SD-WAN Pro box.

100Mbps – SD-WAN Pro
250Mbps – SD-WAN Pro+
500Mbps – SD-WAN Pro-5G

The SD-Wan Pro bandwidth is defined by the level of licencing, ranging from SD-WAN Pro at 100Mbps bonding capability, to 500Mbps bonding capability on the SD-WAN Pro-5G. The actual throughput or internet speed is dependent on the sum of the internet connections used, minus a small overhead for the bonding service. For example, if you had two fixed line 80Mbps download/20Mbps upload connections that you wished to bond, you would see a combined (bonded) speed of roughly 150Mbps download/35Mbps upload.

Bonding sends data over multiple internet connections, using the combined sum of the connections to improve bandwidth and internet speeds.

Once your internet connections are plugged in to the SD-WAN Pro box, the box will automatically set bonding to achieve the optimum bandwidth and internet speeds.

How you setup your SD-WAN Pro box is generally determined by speed of internet and cost of internet.

Where internet connection speeds are similar, bonding will provide greater bandwidth and speeds.

Where internet connection speeds vary greatly, using the slower speed connection as failover would be advisable.

Example: – 1 x Fixed Line and 1 x Cellular SIM card

• High speed fixed line – Primary
• Cellular SIM card – Failover

Example 2: – 2 x Fixed Line and 1 x Cellular SIM card

• High speed fixed line 1 and 2 – Bonded – Primary
• Cellular SIM card – Failover

SD-WAN Pro includes the following security features as standard:

• Encrypted tunnel between the SD-WAN Pro box and our network infrastructure
• Multiple links reduce man-in-the-middle attacks
• Single public fixed IPv4 address allows for whitelisting of the SD-WAN Pro service into other networks for added security

Yes. Every SD-WAN has a single static public IPv4 included as standard.

Yes. We can provide public static IP subnets for applications which require more than one public static IP address.

Yes, SD-WAN Pro is designed to enable multiple location connectivity, globally. This is achieved with an SD-WAN Pro box at each location.

To setup a multi-site deployment using SD-WAN Pro, you would need to speak with one of our in-house technical team members to fully understand and spec the solution required.

No. Any form of fixed, cellular SIM card or satellite internet connection can be used with SD-WAN Pro.

Yes. The SD-WAN Pro has been designed for global use.

Please see POPs.

An external antenna will improve reception of the mobile network carrier and allow for greater throughput and signal quality. An externally mounted antenna can be positioned for optimum signal reception.

A router ‘behind’ the SD-WAN Pro Box, or ‘in front’ of it, or both? A router ‘in front’ of the SD-WAN Pro Box can be any router used to supply internet connectivity. It could be a 4G or 5G router, a fixed line ADSL/VDSL router, or any internet gateway device which supplies an internet connection. A router ‘behind’ the SD-WAN Pro Box is potentially required if there is no existing LAN at the site of deployment. There could also be infrastructure behind the SD-WAN Pro Box, such as a firewall, a switch, access points etc. that form the LAN functionality. The SD-WAN Pro Box is a gateway device primarily, so can integrate with existing networks.

The static IP of the box enables our technical team to provide full remote management of every SD-WAN Pro.
