Anonymous communication is useful in variety of online applications. Evoting, online chat software and data collection for surveying are some of the applications where anonymity is an important feature. One way to guarantee anonymous network communication is using a mix network (mix-net) protocol. A mix network is a protocol that contains several mix servers. A mix server collects user’s cipher...

AIM Workload Mixes • Domain Server Mix “typical” for Enterprise shared servers (50 tests) – Email Network routing – Spreadsheets Word Processing – File Transfers Network Maintenance • File Server Mix (37 tests) – different size file transfers (synch & asynch) – network routing security checking – heavy memory use IPC calls • Custom User Mix – varying the mix to model your applications – add C-s...

In the Internet, video streaming requires greater amount of network bandwidth and other resources as the number of user requests increases. In case of traditional centralized directory server approach all the users requests are directly handled by the centralized server and each user request will send dedicated stream by the server, which requires higher end server, server cost will become more...

Welcome to the special issue of Peer-to-Peer Networking and Applications. This issue contains a collection of the best papers out of various authors who have been submitted to this special issue. Most multimedia-based content service environments are embedded in a large-capacity server and adopt the client–server model. In such a model, excessive load on the server can slow down or break the ne...

In the Internet, multimedia services, such as video streaming, TV conference, should be supported by multicast communications, i.e. IP multicast, in order to reduce total bandwidth necessary for distributing streaming programs. Below data-link layer, IP can use any network technology and ATM is the most promising one for a backbone network. IP multicast is based on the connection-less communica...

DHCP Server as part of the network infrastructure in charge distributing host configurations to all devices has potential be controlled. If is successfully controlled, connected server can potentially From observations made at PT. Rekayasa Engineering found a vulnerability that experience Rogue or Spoofing, where client will fail communicate with authorized Server, well open door for attackers ...

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...

Distribution of streaming media content, including live news, music and videos, is becoming increasingly popular in today’s Internet. Traditional client/server architectures are inefficient for distributing streaming media objects because of the high demands for system resources, especially server and network bandwidth, which severely limit the total number of simultaneous users the system can ...

In this paper, we are concerned with the problem of deploying two servers in a tree network, where each server may fail with a given probability. Once a server fails, the other server will take the whole responsibility of service for all vertices (clients). Here, we assume that the servers do not fail simultaneously. In the backup 2-center problem, we want to deploy two servers at the vertices ...

This paper analyzes an M/M/2 queueing system with two heterogeneous servers. Both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. The vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. The system is analyzed in the steady st...
