PROPOSED ARCHITECTURE ON- A HYBRID APPROACH FOR LOAD BALANCING WITH RESPECT TO TIME IN CONTENT DELIVERY NETWORK

ABSTRACT Content Delivery Network (CDN), is a network having a large distributed servers deployed in multiple data centres on the internet. The goal of this network is to serve requests from users providing high performance and less delay and QoS. The CDN reduces the risks of system failure using redirection to many replica server means copies of the contents are copied onto several mirrored web servers. So the client can directly access any server with less delay. Sometimes the servers are allocated to provide the service to request of users without having the prior knowledge about load onto that server. It may congestion occur or discard the users request. So many load balancing algorithms are used to maintain the balance on the mirrored servers. In this paper, we proposed a hybrid load balancing architecture which is a combination of least loaded algorithm and random balancing algorithm. The new term is defined here, which is a token. Token is used for maintaining the status of replica servers. According to the token information the replica server is assign to the particular users request.
