The Mirrored Server (MS) architecture for network games uses multiple mirrored servers across multiple locations to alleviate the bandwidth bottleneck and to reduce the client-to-server delay time. Response time in MS can be reduced by optimally assigning clients to their mirrors. The goal of optimal client-to-mirror-assignment (CMA) is to achieve the minimum average client-to-mirror delay cons...

A high performance Layer-4 load balancer (LB) is one of the most important components a cloud service infrastructure. Such an LB uses network and transport layer information for deciding how to distribute client requests across group servers. crucial requirement stateful per connection consistency (PCC); namely, that all packets same will be forwarded server, as long server alive, even if pool ...

The growing popularity of Internet Distributed System has drawn enormous attention in business and research communities for handling large number of client requests. These requests are managed by a set of servers. However, the requests may not be equally distributed due to their random nature of arrivals. The optimal assignment of the requests to the servers is a well-known NP-hard problem. The...

We consider network design problems for information networks where routers can replicate data but cannot alter it. This functionality allows the network to eliminate data-redundancy in traffic, thereby saving on routing costs. We consider two problems within this framework and design approximation algorithms. The first problem we study is the traffic-redundancy aware network design (RAND) probl...

In this paper we seek to categorize the set of clients communicating with a server on the Web based on information about these clients that can be determined by the server. We use this information to help drive tailored actions on the part of Web servers. Users with poor connectivity may choose not to spend much time at a Web site if it takes a long time to receive a page, even if the Web serve...

Replication of web content in the Internet has been found to improve service response time, performance and reliability offered by web services. When working with such distributed server systems, the location of servers with respect to client nodes is found to affect service response time perceived by clients in addition to server load conditions. This is due to the characteristics of the netwo...

Video conferencing is a visual and audio communications technology dedicated to Smartphones. It is based on the client-server communication model that this requires many limits since using the server. In this paper, we proposed a new communication model without going through the server (client-client), in addition, this model makes video conference used by mobile multimedia phones. Keywords—vid...

“Machine learning as a service” (MLaaS) in the cloud accelerates adoption of machine techniques. Nevertheless, externalization data on raises serious vulnerability issue because it requires disclosing private to provider. This paper deals with this problem and brings solution for K-nearest neighbors (k-NN) algorithm homomorphic encryption scheme (called TFHE) by operating end-to-end encrypted w...

Database systems support recovery, providing high database availability. However, database applications may lose work because of a server failure. In particular, if a database server crashes, volatile server state associated with a client application’s session is lost and applications may require operator-assisted restart. This prevents masking server failures and degrades application availabil...

In client-server-based interactive information visualization user interfaces, multimedia data sets of many types are made accessible by a server. Users request such multimedia data sets and client user interfaces visualize them applying a given information visualization mapping. On the server side, these multimedia data sets can, e.g., be stored in a file system. As soon as a user requests the ...
