Choose the optimal VPN service

Home » Webinars » Virtual Private Networks » Choose the optimal VPN service

This entry-level webinar offers a comprehensive overview of modern VPN services, from MPLS-based VPN services offered by the service providers (Layer-3 MPLS/VPN, point-to-point links and VPLS), to VPN services you can build on top of generic IP infrastructure (GRE, IPsec, DMVPN, GETVPN, SSL VPN). Description of each VPN service also includes its benefits, drawbacks and design guidelines.

26:24 Free items Introduction, Terminology and Requirements

This section defines Virtual Private Networks, describes their typical topologies, as well as requirements and decision points you should consider when either buying or building a VPN service.

1:36:16 Provider-Controlled VPN

You could build your own VPN or buy it as a service from a Service Provider. This section describes the customer perspective of typical Service Provider offerings including:

  • Layer-3 VPNs implemented with MPLS/VPN or EVPN/VXLAN technology
  • Layer-2 point-to-point or point-to-multipoint circuits
  • Virtual LAN (E-LAN or VPLS) services

1:28:50 Customer-Built VPNs

You might want to build your own VPN on top of Internet to keep the costs low, or do the same on top of provider-built VPN because you don't trust their skill. This section gives you an overview of most popular technologies you could use.

32:42 Hybrid and Multi-Provider VPN

Want to use MPLS/VPN as your primary WAN with Internet-based VPN as a backup? Or run your own MPLS/VPN on top of DMVPN or IPsec because you have many internal tenants but don't own WAN infrastructure?

This section describes several hybrid VPN architectures, and introduces Software-Defined WAN - most commonly an orchestration layer on top of a proprietary hybrid VPN solutions.
