Local transparency means that the location of distributed components in a computer network are hidden for the user of the net. All available components are resources or elements of the network-connected computers. The access to such distributed elements is realized in network operating systems and distributed operating systems via the client/server organization model. This model subdivides the ...

Networking servers, such as web servers, have been widely deployed in recent years. While developments in the operating system and applications continue to improve server performance, programmable network interfaces with local memory provide new opportunities to improve server performance through extended network services on the network interface. However, due to their embedded nature, programm...

With the explosive growth of the Internet have come problems of increased server load and network latency. This means that systems that require interchange of data between server and client over the network can be slow to unusable (at peak times). We are investigating methods for developing distributed CBR systems which minimise the load on the servers and the network, thus increasing response ...

Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...

Video-on-demand applications must consider the bandwidth limitations at the server, within the network, and at the client. Recent multicast delivery techniques have addressed the server and network bandwidth bottlenecks. These techniques, however, neglect consideration of client network access bandwidth limitations. Client bandwidth is often insufficient to permit streaming video of the quality...

Multimedia streaming applications consume significant amounts of server and network resources due to the high bandwidth requirements and long durations of audio and video clips. For popular videos, periodic broadcast techniques exploit the client’s buffer space and network reception bandwidth capabilities to reduce server and network transmission bandwidth requirements. In this paper, we system...

Server selection is an important problem in replicated server systems distributed over the Internet. In this paper, we study two server selection algorithms under a server-based framework we have developed. These algorithms utilize server load and network performance information collected through a shared passive measurement mechanism to determine the appropriate server for processing a client ...

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for information related to the Name Server function of a Fibre Channel network. The Fibre Channel Name Server provides a means for Fibre Channel ports to register and discover Fibre Channel names and attributes. DeS...

This paper describes the design of an online handwritten characters recognition server. Currently, fast and accurate recognition of online handwritten characters requires a high-performance CPU and a large memory space. However, PDA and other small portable devices lack the qualification. To solve this problem, we employ a network environment and build an on-line handwritten characters recognit...

Controlling the timing performance of a network server is a challenging problem. This paper presents a Queueing Model Based Feedback Control approach to keep the timing performance of a network server close to the service level specification. We show that in an instrumented Apache server, combining feedback control with a queueing model leads to better tracking of QoS specifications than with f...
