VPNs
Basically, a VPN (virtual private network) is a private network that uses a
public network (usually the Internet) to connect several sites together. It
typically includes several WANs. Many companies create their own VPN to
provide a secure network connection between two sites. One drawback to
VPNs, however, is that while the network is secure, throughput can be slow.
If a VPN is used to connect several sites in a CC2000 management system, the
only CC2000 server that is absolutely necessary to manage that system is a
single Master server – rather than the network of Master and slave CC2000
servers necessary with the standard Internet deployment. We recommend that
at least one CC2000 slave server is deployed, however, in order to provide
redundant services to the connected devices.
Another advantage of deploying additional CC2000 slaves is that they can
provide more efficient operation and management by speeding up network
traffic.
