Test With Real VPN Clients
TeraVM can be used to act as many individual users on a network, including VPN based users such as Cisco AnyConnect SSL VPN clients with applications, Cisco AnyConnect IPsec VPN clients with applications. This is not ‘simulation’ of VPN traffic, but rather TeraVM acting as real remote workers making many individual valid connections on Cisco FTD/ASA and sending and receiving application flows. TeraVM measures both performance of VPNs and applications in real time. TeraVM also emulates and measures other VPN clients at scale.

Understanding VPN Client Performance
Defining the correct balance of security policies for a VPN client is essential in ensuring network security and the ability to deliver a reasonable level of Quality of Experience for the tunnelled application. Testing secure sever gateway performance is not only dependent on the performance of the tunnel establishment, but also the ability to test application performance e.g. video, voice and data in the configured tunnels. In addition for users to debug application based issues they will require unencrypted packet captures.
Per Flow Enables Unique Applications Per Each and Every VPN Client
Our stateful VPN clients are used to represent real-world scenarios where each VPN client is unique. In addition, the per flow architecture is used to enable emulation of a number of concurrent applications such as voice, video and data being encrypted in the tunnel.
VPN Emulation Use Case
A sample usage scenario is to emulate real IP Phones; establish connectivity with a Call Manager/firewall using TLS sessions and traverse RTP using SRTP. VIAVI is used to emulate thousands of unique VPN clients, providing performance measurements in real time per; MAC, DHCP V6/V4 session establishment, individual TFTP registration with Call Manager, individual parsing of TFTP information per emulated VoIP end point model, SIP/TLS session, RTP/SRTP session with Call Manager.
Targeted Device Testing
VIAVI is used extensively in testing performance of secure VPN appliance, enterprise call management devices, firewalls, IMS Session Border Controllers and layer 4-7 application scalability.
