For example, restricting critical data, ERP and financial application traffic to MPLS and using Internet VPN for email, web and non-critical data.

Node-to-Node Traffic Acceleration

The Internet VPN hybrid network offers any-to-any communication, enabling you to interconnect multiple sites, including Enterprise Cloud hosted private clouds and third-party cloud services, like Amazon AWS and Microsoft Azure. It also provides seamless connectivity to our cloud-based, software defined networking (SDN) and network function virtualization (NFV) enabled network services.

Dynamic Multipoint Virtual Private Networking (DMVPN)

NTTCom's Internet VPN uses Dynamic Multipoint Virtual Private Networking (DMVPN) technology, with globally distributed DMVPN controllers integrated into our MPLS backbone. DMVPN is a tunneling technology that brings flexibility, scalability and discoverability to any-to-any network connections. The technology can be combined with IPSEC encryption for increased security. DMVPN enables you to optimize performance, throughput and latency for any-to-any communication between any site (“site-to-site” traffic).


NTTCom's Internet VPN turns the Internet into a cost-effective network transport. The technology supports any Internet access option, including Internet Service Providers (ISP) that use cost-effective dynamic IP addresses.
