4.
Check for Internet connectivity.
5. Turn on the Exinda Appliance and check for Internet connectivity again.
There are a few Exinda Appliance basics to keep in mind while planning a deployment.
For more information, refer to
Basic characteristics and behaviors of Exinda Appliances (page 17).
Capabilities provided by a main site internet link topology
In a Main Site Internet Link topology, an Exinda Appliance:
Monitors all network traffic going to and returning from the Internet/WAN.
Monitors application specific network traffic going to and returning from the Internet.
Controls network traffic on the Main Site by allocating bandwidth to Main Site network users and setting priorities for
Internet-based applications accessed by Main Site network users.
Monitors and controls network traffic from Branch users and the Internet to servers and applications hosted on the
Main Site.
Limitations of the main site internet link topology
Monitoring and controlling Branch Site traffic to the Internet is impossible because the Exinda Appliance is not
inline between the branch offices and the Internet. If you want to monitor and control network traffic for a geo-
graphically dispersed user base that connects to the Internet through multiple routers outside your LAN, use a different
deployment strategy.
One of Exinda's top features is Application Acceleration. With only one Exinda Appliance deployed, Application
Acceleration isn't available because it requires at least two Exinda Appliances.
Overcoming the limitations of the main site internet link topology
If you only have one Exinda Appliance but need to monitor and control network traffic to the Internet from users out-
side the Main Site, disable direct access to the Internet for branch offices and route all Internet-bound traffic through
the Main Site.
NOTE
Routing Internet-bound traffic from users outside your Main Site through the Main Site router introduces an extra leg
of travel for network packets and could cause a spike in the Main Site's router utilization.
Install an Exinda Appliance at each branch. Essentially, you replicate the Main Site Internet Link topology at each
branch. Installing multiple Exinda Appliances into your network environment allows you to implement Exinda's pro-
prietary, performance-boosting Application Acceleration technology.
Main site WAN link topology: multiple sites with one Exinda Appliance
This topology is used to monitor and control Internet and WAN traffic in the main site and WAN traffic from the branch
offices. The Exinda Appliance monitors and controls Internet and WAN traffic on the main site and WAN traffic from
branch offices. The Exinda guarantees traffic for the WAN and treats applications and users from different branch offices
with different priorities.
