This ERR algorithms works better than Longest Wait First For Broadcast Scheduling, FCFS, SJF, Priority and Round Robin algorithms. The main advantage of this algorithm is, ERR minimizes the average flow time between the request and response, minimizes the waiting time and turnaround time of the requests. | ISSN:2249-5789 Sukumar Babu Bandarupalli et al, International Journal of Computer Science & Communication Networks,Vol 3(1), 46-53 ERR Broadcast Scheduling Algorithm Sukumar Babu Bandarupalli1 Neelima Priyanka Nutulapati2 Dr. P.

In this paper the ERR is a pull based broadcast model, where the server stores n unit sized pages (or n different sized pages) of information. This server is connected with multiple numbers of clients requesting for the pages of the server. The server processes the request and sends the response to all the pages that are requesting for the same page at a time. The main use of this broadcast algorithms is instead of processing the pages individually, the ERR algorithm process one request of same type and sends the response to all the clients who are requesting for the same page at that instant of time. This method reduces the overhead on the web container of a server. This ERR algorithms works better than Longest Wait First For Broadcast Scheduling, FCFS, SJF, Priority and Round Robin algorithms. The main advantage of this algorithm is, ERR minimizes the average flow time between the request and response, minimizes the waiting time and turnaround time of the requests. 1. Introduction Generally in client server technology the client sends the requests to the server for a particular page to access. The process each request of the clients and sends the response to the client. The client requests for n-pages available at the server. In this process, it very tedious and becomes overburden for the server in processing each request received from the multiple clients. For processing and sending
