Calls break up. Cloud apps slow down. One site behaves differently from another. And IT teams can spend too long working out whether the problem sits with the application, the connection or the network itself.
SD-WAN helps bring that under control by prioritising important traffic, using available connections more intelligently and giving you clearer visibility across sites.
Network visibility | Application priority | Multi-site control | Resilient routing
what sd-wan changes
As teams rely on Microsoft 365, Teams, cloud platforms, voice and customer systems throughout the day, network traffic becomes harder to manage. Add multiple sites and different connection types, and the experience can start to vary significantly from one location to another.
People feel that as slow applications, poor call quality or inconsistent performance. IT teams feel it as more troubleshooting, less visibility and too much time trying to work out whether the problem sits with the application, the connection or the network itself.
SD-WAN gives you a way to bring more control to that complexity - helping important applications get priority, making better use of the connections already available and giving you a clearer view across sites.
That gives users a more consistent experience while making performance easier for IT teams to manage.
WHAT SD-WAN CHANGES
When several applications are competing for the same connection, the things people rely on most can suffer first. Calls break up, video struggles and cloud applications slow down simply because something else is using the available capacity.
SD-WAN gives you more control over how that traffic moves. It identifies different types of traffic and applies rules around application priority, connection performance and availability - so important services can use the most appropriate route.
Give voice, video, CRM and other important services preference when several applications are competing for the same available capacity.
Combine suitable broadband, dedicated access and mobile backup rather than relying on a single circuit at every site.
Move traffic to another available connection when performance drops or the primary route becomes unavailable, subject to the backup design.
Use central reporting and management to understand site status, connection performance and how application traffic is moving.
BUILD THE RIGHT UNDERLAY
SD-WAN cannot make an unsuitable connection suitable. If a site does not have enough capacity, or there is no alternative route when the main line fails, software alone cannot solve the problem.
The underlying connectivity still needs to fit the site. That could mean dedicated access for a critical location, FTTP for a smaller branch, or mobile backup where important services need another way out.
Use dedicated connectivity at critical sites where predictable performance, symmetrical capacity and stronger service levels justify the investment.
Use cost-effective fixed connectivity at branches and offices where it gives users and applications the capacity they need for everyday work.
Add a mobile route where coverage and capacity are suitable, giving priority services another way to stay connected if the main circuit is disrupted.
Give each site the combination it needs rather than forcing every location onto identical circuits simply to make the network look consistent.
TECHNOLOGY BEHIND THE SERVICE
Managing sites one by one gets harder as the estate grows. Different connections, local changes and inconsistent settings can leave IT teams spending too much time troubleshooting individual locations instead of seeing what is happening across the network.
Where it fits the design, Cisco Meraki SD-WAN can bring routing, policies, visibility and failover into one cloud-managed environment, while still allowing each site to have the setup it actually needs.
01
Define which traffic matters most and how it should behave when bandwidth is limited or network conditions change.
02
Manage settings and visibility across multiple sites without turning every local change or performance query into a separate project.
03
Separate different types of traffic or user groups where operational, security or governance requirements need clearer control.
04
Set how traffic should move when one connection fails, then test the design against the calls, systems and services that need to keep working.
Where it helps
SD-WAN becomes particularly useful when network problems start affecting the working day.
One branch performs differently from another, Teams calls struggle when traffic increases, cloud applications feel inconsistent or IT teams have little visibility into why a site is having problems.
By managing applications, connections and routing more centrally, the network can respond more consistently without forcing every location into exactly the same design.
01
Create more consistent routing and visibility across offices, branches and operational locations using different types of connectivity.
02
Give Microsoft 365, SaaS platforms, calls and collaboration tools network treatment that reflects their importance to the working day.
03
Prioritise voice and contact centre traffic so calls are less likely to suffer when other network demand increases.
04
Manage payments, stock systems, guest traffic and cloud applications across distributed sites with clearer central control.
ONE ACCOUNTABLE TEAM
An SD-WAN project should start with what your teams rely on, where performance is already causing problems and what needs to stay available if a connection fails - not with choosing a piece of hardware.
With dbfb, that understanding shapes the connection mix, application priorities and failover rules at each site. One team can then support the connectivity and SD-WAN together, with ongoing account management as locations, applications and requirements change.
01
Start with the calls, cloud platforms and operational systems people actually depend on, so network priority reflects business impact.
02
Use suitable fixed, dedicated and mobile connectivity where it gives each location the right balance of performance, resilience and cost.
03
Plan alternative routes and failover around what needs to keep working, then test that behaviour rather than assuming resilience exists.
04
Add sites, change priorities and review performance without turning every network change into a new standalone project.
CONNECTED SERVICES
SD-WAN does not replace the connections underneath it. It helps manage how those connections are used, so the wider network design still matters. Combining the right circuits, resilience and application priorities gives SD-WAN a stronger foundation to work from.
Align routing and priority with cloud telephony, contact centre and other real-time communication traffic.
Combine suitable fixed connections with smarter routing and application control across each location.
Add secondary circuits, 4G or 5G backup so traffic has another route when the primary service is disrupted.
Use 4G, 5G or satellite when a new site needs to join the networkbefore fixed connectivity is ready.
quick answers
SD-WAN stands for software-defined wide area network. It is a software-defined approach to managing and routing application traffic across sites, cloud services and different connection types.
No. SD-WAN sits above the underlying connectivity and manages how it is used. Those connections might include FTTP, business broadband, dedicated internet access, 4G or 5G, depending on the site.
No. SD-WAN does not make the underlying circuit faster. It can make better use of suitable connections, prioritise important traffic and choose another available route when the design allows.
It can help by prioritising real-time voice and video traffic when the network is busy. The underlying broadband, WiFi, local network and available capacity still need to be suitable.
If more than one suitable route is available, SD-WAN can move traffic according to agreed failover rules when a connection fails or performs below the configured policy. It still needs a genuine alternative connection underneath it.
It is worth considering when you have several sites, rely heavily on cloud applications, need better visibility across the network, use different connection types or find important applications competing for performance.
