Business Connectivity: SD-WAN, MPLS & Dedicated Internet

Choosing how your sites connect to each other and to the internet is one of the most important technology decisions a growing business makes. Three terms come up constantly: dedicated internet, MPLS and SD-WAN. They solve different problems, and many organizations use a mix.

Dedicated internet access

Dedicated internet access (DIA) gives a site its own guaranteed bandwidth to the internet, usually over fibre and backed by a service-level agreement. Unlike a shared business plan, the capacity is not divided with neighbours. It suits head offices, data-heavy operations and companies that run important cloud applications or host services. It costs more than standard business internet, so confirm that you need the guarantee before paying for it.

MPLS

Multiprotocol Label Switching is a private wide-area network run by a carrier. Traffic between your locations travels over the provider's managed network rather than the public internet, which can give predictable performance and prioritisation for voice and critical applications. MPLS is proven and stable, but it is typically priced higher than internet-based options and can be slow to add new sites.

SD-WAN

Software-defined WAN links your sites using ordinary internet connections, such as fibre, cable or wireless, and a central policy decides which path each type of traffic uses. It can combine more than one connection, fail over automatically when a line drops, and make adding a new location faster. Quality still depends on the underlying internet lines, so reliable local connections remain important.

How to choose

Start with how your teams work. Do you run voice and video between sites, rely on cloud software, or move large files? How many locations do you have, and how quickly do you add new ones? What does an hour of downtime cost? A small group of offices may be well served by business fibre with a mobile backup line. A retail chain or clinic network with many sites may gain from SD-WAN. A site with strict performance needs may justify dedicated internet or MPLS.

Plan for failure

Whatever you choose, plan the backup. A second connection from a different technology or a different provider reduces the chance that one failure stops operations. Our Business Continuity solution covers primary and backup connectivity strategies.
