SD-WAN Delivery

SD-WAN Delivery

As pioneers of SD-WAN (short for Software-Defined Wide Area Network) implementations in Poland, we know the pros and cons of migrations from traditional WAN to SD-WAN. We like to think of SD-WAN as a  revolutionary approach due to the disaggregation of data and control plane. We stick to the ground, and as experienced network engineers can point out many kinds of potential issues on the way to bringing software to your WAN. As much has been said already, the power of SD-WAN from the IT department view is:

  • Ease of administration even for entry network technician
  • Relatively quick SD-WAN setup with different ZTP (Zero-touch provisioning) flavors
  • No need for knowledge of sophisticated routing protocols
  • An overlay network independent of underlying networks, mediums, and service providers
  • Single point of management
  • Ability to route traffic based on applications
  • Alternative to MPLS links from Service Provider


The above points could prejudge in many cases and force decision-makers to buy the SD-WAN solution. For example, a pure calculation that compares the resignation from dedicated MPLS service and switching to SD-WAN, where the latter is based on cheaper Internet and LTE links, can easily convict that SD-WAN is the right way in the long term.

But we can see some specific situations where SD-WAN not necessarily can be of good choice. Good old DMVPNs of GETVPNs structures can still do the job for you. For example, when you have a nice DMVPN design and automation (for example, written in Ansible) and you do not really need app-based routing or two Internet links in the same time utilization. It might be that SD-WAN is not the best choice for you at the moment.

As said in most cases, it is. Still, anyway, you can trust Grandmetric network experts on the way to migrate your WAN to SD-WAN and that they will objectively point you and your organization in the right direction and take care of the details like licensing, appliance, and virtual appliance choose and so on.
