Agilent Technologies’ L2TP Test Solution provides realistic Internet-scale simulation for testing the performance of edge aggregation devices that are involved in providing IP VPN services. Specifically, devices that act as L2TPv2 Network Servers (LNS) or L2TPv2 Access Concentrators (LAC) for delivering L2TPv2-based VPN services are fully stress tested by Agilent’s RouterTester through emulation of the L2TP and the PPP protocols.
