Virtual VPN Server - Virtualized Virtual Private Network Server (Virtualized VPN Server)
What is a Virtual VPN server? A Virtual VPN server (aka virtual private network server or virtualized VPN Server) is a type of router that provides hosting and delivery of VPN services. It may also be viewed as an IP Network instance that terminates VPN connections such as Ipsec, OpenVPN and similar. Traditionally, a VPN server is a hardware computing device installed and configured with software that provides virtual Private Network (VPN) service. Patton has decoupled the VPN software from the dedicated hardware using virtualization technology to create a Virtual VPN Server. The VPN server provide, VPN tunnel management, network protection and firewall security and Ipsec router functionality-as well as VoIP security including TLS/SRTP.

Virtual Enterprise Session Border Controller (eSBC)


vSN eSBC

Deliver scalable, flexible, and reliable SIP-trunk or hosted-PBX communications using Patton's virtualized eSBC. This specialized VNF may be implemented on a virtual machine (VM) in the cloud or on bare-metal uCPE hardware a.k.a. white box hardware. The virtual SBC provides LAN-telephony protection, service demarcation, SIP normalization, quality of service, and network survivability for business continuity-all with high availability through virtualized network technology, including cloud-controlled license key management and Patton Cloud edge orchestration.
 
 

Teach Me: Virtualized VPN Server / VPN Concentrator

 
Most businesses, enterprises, and other organizations use VPN software to allow mobile, remote, and home-office workers to connect privately and securely over the Internet to the corporate network-with all its associated services such as printers, file servers, Intranet services, and so on. The VPN server creates what is known as a VPN tunnel between the client and the business network that hides the private data stream from the rest of world. It also hides the IP address and geographic location of the user from everyone else on the Internet.

The VPN server employs such protocols as point-to-point protocol (PPP) for connectivity and communications. The VPN client (remote worker's computer) must first connect to the VPN server and authenticate (provide a username and password or use a certificate) before access can be established to the Corporate Network So to summarize the VPN concept, let's break it down...

Virtual... you have a private connection to another network which is built in software rather than a dedicated hardware (cabled/wired) link.

Private... all your communications are encrypted and hidden from everyone other than those with whom you want to communicate

Network...you can connect and communicate (network) with other computer resources and users (co-workers, clients, customers, and such).

In summary, a Virtual Private Network is a secure virtual connection established over an unsecure public network such as the Internet.

VPN server software is sometimes created using the open source software model, which allows a community of software developers to modify and enhance the software functionality. Such entities may be referred to as an Open VPN Server or an Open VPN Access Server. The term Security Gateway may also be used to refer to a VPN server or VPN Access Server.

VPN Concentrator
For large organizations, especially those with two or more geographically separated work sites, a standard VPN server cannot support the number of connections required, nor can it handle the volume of traffic generated by thousands of workforce users. In such cases a VPN concentrator (a.k.a. VPN aggregator) is necessary. VPN concentrators can create and manage thousands of VPN tunnels concurrently. So, in site-to-site VPN architectures, VPN concentrators are typically employed. In the traditional hardware-based approach, a separate VPN concentrator appliance is installed at each major office, while each small, home, and remote office also requires a local VPN server unit. Patton's virtual VPN Server can be configured to operate as a virtual VPN concentrator to provide all the same capabilities as a traditional VPN concentrator appliance. Cloud-based network orchestration, offers the multiple advantages of managed scalability for the number of tunnels required and overall traffic capacity-which can all be remotely managed, scheduled, and even automated.

Virtualization technology combined with using cloud-based network-edge orchestration offers several valuable benefits, beginning with touchless, automated service deployment and activation. Whether virtualized and delivered in the cloud, or downloaded for operation on bare metal virtual customer premise equipment (vCPE), VPN router capacity and service equality can be automated and scheduled, based on forecasted demand. By removing the limitations of a dedicated hardware appliance, Virtualization technology offers increased reliability and higher network availability.

VPN Service Providers can profit by using the virtual SmartNode (vSN) VPN server VNF to deliver secure, encrypted VPN service to subscribers. Because it is based on NFV technology, the number of subscribers and the quality of service for each subscriber can be easily scaled up (increased), scaled down (decreased), monitored, managed.

Edge Orchestration
Whether the virtualized VPN software is delivered in the cloud or downloaded and installed on a bare-metal universal CPE (uCPE) at the subscriber premise, Network Edge Orchestration (a.k.a. intelligent edge) is typically required to activate, configure, scale (up or down), monitor and control VNF-based virtualized VPN software service and VPN network implementation.
