52DSView 3 Software Installer/User Guide

Frequent replication of the DSView 3 software database will increase WAN/VPN traffic but provide steady data reception at the local sites. Infrequent database replication made at the various sites decreases the WAN/VPN traffic but delays the reception of changes at the local site.

In addition, the methods used to access devices affects network speed. VPN access of a managed appliance is always slower than local access.

The DSView 3 management software supports VPNs that provide full transparency for IP addresses, as well as ports between sites and many VPNs that perform network address translation (NAT) between sites. For example, the VPN in Figure 4.2 could use NAT if Site A and Site B are separate companies that merged but have not resolved their IP addresses. See NAT Devices on page 53.
