Abstract
A method, Request Router and Traffic Monitor for monitoring a Content Delivery Network effecting requests routing toward delivery nodes (DNs) without using a load balancer and achieving high availability. Iteratively, for each delivery node, sending a monitoring request to the delivery node. If a response indicative of success of the monitoring request is received from the delivery node before the end of a first time interval, setting a status of the delivery node to indicate success. If a response indicative of failure is received before the end of the first time interval, setting the status to indicate failure. If no response is received before the end of the first time interval, setting the status to indicate indetermination. Iteratively, at a second time interval, taking a snapshot of the statuses of the delivery nodes and producing a list of DNs with their statuses to be sent to the RR.
