Improved accuracy and reliability of the real-time user coordinates is expected if GNSS data is processed using the network-RTK technique. Some implementations of conventional network-RTK, e.g. Virtual Reference Station (VRS) techniques, require bi-directional communications via GSM/GPRS since the network server transmits network-corrections to a user, while the user receiver is required to tra...

Kerberos is a network authentication protocol & is designed to provide strong authentication for client/server applications by using secret-key cryptography. Our research was aimed at enhancing the security of transactions over a network. In this paper, we used Kerberos Encryption Technique for authentication and transaction security in the network. Further, we created an Authentication Server ...

This article addresses path selection problems that arise in a large-scale media server. In particular, the problem on a distributed server with two tiers of server nodes connected by a VC-enabled interconnection network is considered. To serve each incoming request, a pair of server nodes should be selected to handle the request. In addition, a network path in the interconnection network shoul...

Mobile Agents are an effective choice for many research and application areas due to several reasons, including improvements in latency and bandwidth of client-server applications, reducing network load and threat assessment. Intrusion Detection Systems and Vulnerability assessment systems are used to monitor network traffic, to measure and prioritize the risks associated with network and host ...

VoIP (Voice over Internet Protocol) is a growing technology during last decade. It provides the audio, video streaming facility on successful implementation in the network. However, it provides the text transport facility over the network. Due to implementation of it the cost effective solution, it can be developed for the intercommunication among the employees of a prestigious organization. Th...

Recently, the Internet has been expanding intensively; the number of WWW (World Wide Web) users has been growing, and the network capacity provided by network carriers and Internet service providers has been increasing for enabling high quality services. The Internet users would pay the reasonable cost for a reasonably better service. For ISP (Internet Service Provider) to provide better QoS (Q...

OF THE THESIS TCP Servers: A TCP/IP Offloading Architecture for Internet Servers, using Memory-Mapped Communication by Kalpana S Banerjee Thesis Director: Liviu Iftode TCP Server is a system architecture aiming to offload network processing from the host(s) running an Internet server. The TCP Server can be executed on a dedicated processor, node or intelligent network interface using low-overhe...

The PATHWORKS for ULTRIX product integrates personal computers with the ULTRIX operating system on a local area network. The software supports both the TCP/IP protocol and the DECnet transport stacks. The design and implementation of the PATHWORKS for ULTRIX file server is based on a client-server model. The server provides file, print, mail, and time services to client PCs on the network. Netw...

Widespread replication of information can ameliorate the problem of server overloading but raises the allied question of server selection. Clients may be assigned to a replica in a static manner or they may choose among replicas based on client-initiated measurements. The latter technique, called dynamic server selection (DSS), can provide signi®cantly improved response time to users when compa...

Incidents related to hacking and network intrusion are on the increase. Most organizations safeguard themselves against cyber attacks by employing security methods such as encryption technologies, network monitoring tools, deploying firewalls and intrusion detection and response mechanisms. Even though prevention mechanisms are in place the vulnerabilities associated with any computer network o...
