and SKIP key management, Network Address Translation (NAT), routing, and
packet filtering.
Security
The VSU-7500 provides data stream privacy by employing cryptographic
algorithms and keys powerful enough for the most sensitive business
communications. It supports DES and Triple DES encryption, as well as the
ISAKMP and SKIP key management standards. Using SKIP, the VSU-7500 is
able to change keys frequently during transmission.
Data authenticity is assured by using MD5
™
or SHA-1 hashing to reject altered
or forged packets. All security mechanisms employed by the VSU-7500 conform
to IPSec standards, in order to provide interoperability and broaden the use of
VPN technology.
Performance
The VSU-7500 supports IP over 10BASE-T or 100BASE-T local area networks
(LANs). When packets are encrypted and authenticated according to IPSec
protocol guidelines, additional bytes—in the form of IPSec headers—must be
added to packets. In many cases, the additional packet overhead imposes a
performance penalty in return for security. The extra bytes tend to lengthen
packets and reduce the throughput (measured in packets per second). Of even
greater impact is the tendency for packets lengthened by IPSec headers to be
fragmented by network routers, causing further reductions in performance and
additional latency. Real-time compression performed by the VSU-7500
eliminates packet fragmentation and produces fewer, smaller packets, which can
significantly enhance network throughput and performance.
Plug-and-Play Installation
The VSU-7500 can be placed anywhere in a 10/100BASE-T LAN to provide
VPN functionality. Native support for IP ensures that the VSU-7500
interoperates transparently with the broadest range of intranet and other network
applications.
The graphical VPNmanager™ (available separately) network management
application steps network managers through the setup process and allows them to
configure a VPN in minutes. The VPNmanager also supports extensive facilities
for VPN monitoring and troubleshooting, and for establishing multi-company
extranets. The VSU-7500 provides support for the RADIUS protocol, enabling
VPNs that support thousands of remote users and a variety of mechanisms for
remote user authentication.
