Network, a collection of two or more nodes that can share the data. In our modern world the rapidly increasing the internet users led to storing and updating the data very often. This scenario led into the data center ( a collection of servers) where it maintain a huge database and thus need high capacities for interconnecting the thousands of servers in these data centers. A range of multilayer architectures have been employed. From this related work that the traffic in a data center is a combination of static and dynamic. To improve the throughput and minimize delay Load Balanced schedulers have been proposed and also incorporate an opportunistic scheduler that sends traffic on a feasible direct path.
