Although several technology vendor-proprietary technologies as well as open up, standards-based technologies are readily available for crafting a Digital Private Face Network VPDN, there are two main techniques of utilizing a VPDN that show up to get increasing in popularity”Layer 2 Tunneling Process L2TP and Point-to-Point Tunneling Process PPTP tunnels. This is a great administrative decision by the service plan provider as to the relative numbers of provisioning of core tranny and transitioning capacity, as well as the ratio of network ingress capacity employed by subscribers.
