Introduction
The VSU-7500 is a high-availability VPN gateway for large-scale, business-
critical virtual private networks (VPNs). Designed to provide the high capacity,
high availability, and fail-over protection required by enterprise and service
provider networks, the VSU-7500 offers extensive fail-over and switch-over
support of redundant Ethernet interfaces, encryption processors, power supplies,
and cooling fans.
Like other platforms in the VPNware family, the VSU-7500 adds compression,
encryption, authentication, and key management to public network data links to
ensure privacy and integrity of corporate data, and to enable the efficient and
secure operation of virtual private networks (VPNs). It is designed to perform
complex operations, in real time, without compromising network performance,
and in many cases can actually increase data throughput. Additional memory
enables scalability to 7,500 simultaneous tunnels.
The VSU-7500 supports a full suite of VPN services including: ICSA-certified
IPSec-based encryption, data compression, packet and user authentication, IKE
