Optimization of the Dispatch Probability of Service Requests for Two Servers in Parallel Connection
نویسندگان
چکیده
This paper describes the procedure used to create a queueing model for servers which are currently in parallel connection with different dispatch probabilities. The system response time of parallel Web servers is improved by calculating dispatch probabilities. The system response time is calculated first. The equation for the lowest system response time is obtained by adjusting the equation to meet the dispatch probability requirements. Then the system response time of the servers is measured. Last, the errors in the system response time of the servers are compared by simulating, modeling and measurement. Key-Words: Service rate, Optimization of the Dispatch probability, Parallel connection, System response time, Queueing Model, Different Dispatch Probabilities, Equivalent model.

Analysis and Modeling of VoIP Servers: A Linear Programming Approach
The SIP protocol was standardized by the IETF at the application layer for initiating, managing, and terminating multimedia sessions and has been widely used as the main signaling protocol on both the Internet and VoIP networks. Most challenges in this protocol are overload and lack of proper state distribution. These challenges cause a wide range of next-generation network users to face a shar...

Some servers are to be located at nodes of a network. Demand for services of these servers is located at each node and a subset of the nodes is to be chosen to locate one server in each. Each customer selects a server with a probability dependent on distance and a certain amount of benefit is achieved after giving service to the customer. Customers may waive receiving service with a known prob...

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...

Reliability investigation has always been one of the most important issues in power systems planning. The outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. Using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...
