SD-WAN based on ePN-WAN

SD-WAN in the Australian Context

 

  • SD-WAN is often explained for Multinationals or for large U.S. companies
  • Australia has a different business structure, typically 10-50 branches/offices
  • The NBN is everywhere at the same prices (soon) in Australia
  • Most Private Network (e.g. MPLS) prices in Australia are lower than U.S. and close to basic commercial Internet prices
  • Cost savings are not as clear
  • SD-WAN has no agreed standards, each vendor is different

What is an SD-WAN?

 

  • SD-WAN is an overlay network on top of other networks
    • A hybrid sits over an MPLS network and Internet links
  • Each branch office has access to multiple network links through an SD-WAN control box
  • A central controller signals to each branch control box to direct the data layer
  • There is often encryption used end-to-end to avoid Internet security issues
  • Often enabling access to SaaS via the Internet or the Data Centre
  • Cost savings can be made if low-cost Internet links are used
    • This will not avoid latency and jitter problems over the Internet

ePN-WAN
either Stand-Alone or as part of an SD-WAN

  • Forms an Ethernet Private Network (ePN) WAN from various access types
    • NBN, Optical Fibre, ADSL, Microwave, etc.
  • Basic MPLS network with VPLS overlay (“blue cable” connectivity)
  • Similar to an SD-WAN, the ePN uses Mikrotik routers to form the Control Plane
  • A central MPLS/VPLS switch efficiently directs traffic in the Data Plane
  • Multiple variable VPNs provide security and QoS across the WAN
  • Access to SaaS (or DRaaS or IaaS) is provided via the Internet or the Data Centre
  • Low latency and jitter over the ePN-WAN
  • Access to the Internet at a controllable central point

The ePN-WAN is excellent in its own right – simple to set-up, operate and maintain; secure, reliable and with excellent performance parameters

As part of an SD-WAN the ePN-WAN becomes one network of several that the SD-WAN Control Plane can choose from
