Abstract In this research, we propose an architectural solution to implement file transfer service (FTP) in IPv6 environment network. IPv6 is considered to be the next-generation Internet protocol. Thus, this study is to analyze the size of files transfer performance and to measure Quality of Service (QoS) delivered by IPv6 using best effort approach in comparison to IPv4. This study primarily... In this research, we propose an architectural solution to implement file transfer service (FTP) in IPv6 environment network. IPv6 is considered to be the next-generation Internet protocol. Thus, this study is to analyze the size of files transfer performance and to measure Quality of Service (QoS) delivered by IPv6 using best effort approach in comparison to IPv4. This study primarily focuses on file transfer speed quality of FTP. In the experiment, both host clients and routers utilize the same technical specification. In the same study also, network management system (NMS) is used to monitor and to capture the performance of file transfer in IPv6 and IPv4 environment. Based on the finding result, it shows that there is a slight but significant difference in file transfer performance between dual stack tunnelling IPv4 and IPv6 protocol. Small size file transfer will result in lower and same delay performance outcome for both IPv4 and IPv6, while large size file transfer over IPv6 will result in higher delay performance as compared to IPv4. In short, the significant result of IPv6 delay is slightly higher than IPv4. Hence, the quality of FTP might be decreased if dual stack tunnelling is implemented in IPv6 environment. Nevertheless, Link Efficiency and compression technique are able to lower the delay performance on file transfer over IPv6 environment. Read More Read Less

This article designs and implements a low cost two-tier architecture model for high availability cluster combined with load-balancing technology and shared storage technology to achieve full facilities of the three-tier architecture for application load balancing e.g. web servers. The paper described design physically omits Network File System (NFS) Server Nodes and implements NFS server functionalities within the Cluster Nodes, through Red Hat Cluster Suite (RHCS) with High Availability (HA) Proxy load balancing technologies - in order to achieve low-cost investment in expensive hardware and computing solutions. This system can provide continuous service though any system components fail uncertainly such as network system, storage and application. Read More Read Less
