Web servers have become increasingly powerful since they were created. The services they offer have changed as computer hardware has improved, networks have sped up and people demand more interaction for their Web browsers. Web servers perform their function well. They are built purely for one purpose, namely speed. Web servers have sacrificed some functionality by prioritizing efficiency and s...

In many congestion problems, the customers may not like to join a long queue and may balk. To reduce the balking behavior of the customers, the provision of additional servers can be made in such situations. In the present paper, we investigate a Markovian queueing model with balking, interdependent rates and additional servers under no passing constraint. Due to nopassing restriction, the cust...

abstract—today, botnets have become a serious threat to enterprise networks. by creation of network of bots, they launch several attacks, distributed denial of service attacks (ddos) on networks is a sample of such attacks. such attacks with the occupation of system resources, have proven to be an effective method of denying network services. botnets that launch http packet flood attacks agains...

Objectives: Modern data centers serving web and mobile applications employ distributed load balancers. The Join Idle Queue (JIQ) algorithm is ideally suited for balancing in a setup. It attains fast response time by directing service requests to idle servers which can immediately process them. However, JIQ not optimal tracking leaving room improvement.
 Methods: We observed that assigns no...
