CLOUD VPN GATEWAY

Simplifying VPN Deployments In Enterprise and Service Provider Networks

ALTEN Calsoft Labs provides a carrier grade Cloud VPN Gateway framework that simplifies VPN Deployments for enterprises. The platform offers standards based IPsec VPN services and management functionality with significantly higher performance as compared to legacy Cloud VPN Gateway appliances. Our framework addresses network service providers’ need, to deploy a future proof, scalable, carrier-grade IPsec VPN Gateway infrastructure that delivers breakthrough performance on industry standard X86 hardware. The framework has been architected to leverage Intel DPDK to deliver up to 25x performance gain in packet processing on IA, and extensively tested on commonly available servers with Intel Xeon processors.

A Cloud VPN Gateway solution is used to provide VPN connectivity to Wi-Fi users or wired residential/enterprise broadband subscribers. It forms an integral part of a Virtual CPE solutions with the addition of Firewall, VNF Manager, VNF Orchestrator, IDS/IPS and other services along with the IPsec VPN Gateway.
