of a group of servers that service the same domain, website or services. For
example, to configure a farm (or virtual farm) to serve www.cainetworks.com:
•
First, Server 1 and Server 2 would each need the website
www.cainetworks.com configured on them and HTTP/HTTPS services
started, and
•
Second, a farm on the WebMux™ is defined with Server 1 and Server 2 in
it. The servers would be setup to either share the traffic, or setup as a
primary server and standby server. In either case, if Server 1 goes down,
then all traffic will be automatically directed to Server 2 by the WebMux™.
In Out-of-Path mode, only one network in the setup, that is the server LAN, is
connected to the Internet through the firewall and router. Internet traffic or local
connections can both be directly sent to the WebMux ™ , which routes the
packets to the proper server(s), then the server routes the return traffic back to
the remote or local clients directly.
In most situations, the incoming traffic is in small requests, and return traffic from
servers back to clients is large amount of data, pictures, or documents. Using
direct routing will allow up to 100 times more traffic to be handled by the
WebMux™ load balancer. The disadvantage for direct routing is that the firewall
protections built-in to the WebMux™ will no longer function. Users then must
provide their own firewall for incoming and outgoing traffic.
