TrafficDefender

TrafficDefender can be installed either in front of a web server/server farm or accessed from the cloud to act as a first line of protection when a site becomes overloaded with traffic - providing a “silver bullet” for any company experiencing immediate performance issues.

TrafficDefender can be rapidly deployed to alleviate the immediate problems of extreme peak load, restoring a site to an acceptable level of service. In the case of the cloud-based service this will simply involve re-pointing your websites domain name to the hosted TrafficDefender service. Once operational, TrafficDefender can then be used to continuously manage site traffic and remove the need to permanently scale infrastructure to meet peak demand.

How it Works

TrafficDefender operates by allowing only a fixed number of visitors to access a site while redirecting any excess traffic to a busy page or queuing system to preserve the level of service provided to visitors gaining access to the site during busy periods:

System Not Busy
If the system is not busy – visitors will be directed straight to the site by Traffic Defender. The “Busy” threshold is determined by setting a parameter e.g. “2000 visitors”.

Busy System
If the system is too busy (exceeding the threshold set) and queuing has not been enabled on the TrafficDefender device – the visitor will either be directed to a busy page or be directed to a secondary system if one exists.

Queuing System
If the system is too busy (exceeding the threshold set), and queuing has been enabled on the device TrafficDefender identifies a visitor and assigns a number to it which is stored on the device. TrafficDefender then returns a queuing page to the visitors browser – displaying their current position in the queue. Visitors are allowed access to the system based on the users order of arrival set by their number.

Benefits

Unlike the majority of existing market-leading devices, TrafficDefender measures the actual number of visitors accessing the system, ensuring that when traffic thresholds are reached –existing visitor connections to the site will be retained without losing connection mid-transaction.

TrafficDefender will thus enable you to:

  • Meet peak demand without permanently scaling infrastructure.
  • Avoid high profile performance failures at critical trading periods.
  • Measure and limit the number of real visitors to a site.
  • Physically hosted or cloud based protection.
  • Rapid deployment.
  • Lease or purchase options.
