IP address mutation is a proactive defense method that is used to reduce the risk of network attacks, especially to deal with the worm propagation attacks. However, previous work did not give much consideration to the negative effects that IP address mutation could bring to network performance. To be specific, there is a trade-off between network performance and security, which implies that when a...
With the current limitations of network technology, jumbo frames provide a mechanism that can allow greater amount of data transfer efficiently on cables. Implementation of jumbo frames is a viable option on Gigabit Ethernet. In this research undertaking, the authors implement jumbo frames on a test-bed implemented with Windows routers and performance related metrics are measured for both IPv4 and...
HTTP is the most popular application-layer protocol in the Internet. Improving the performance of HTTP packets reassembly is the key point of HTTP traffic analysis. In this paper, we first parallel the traditional serial HTTP packets reassembly system according to the HTTP protocol features. This optimization improves the throughput of packets reassembly system by 45% on the generic multi-core platform...
The aim of this study is to quantify performance of network file transfer for research testbed. This study was carried out because Internet users nowadays has surfing tendency to stream video, download and upload video which need more Internet bandwidth. In addition, there is also a requirement for clarification between theoretical and actual performance of Internet Protocol version 6 (IPv6). This...
In a bare PC softphone, the VoIP application runs directly on the hardware without any Operating System (OS). Such softphones are useful when security and/or performance concerns outweigh the need for a conventional system. We evaluate the overhead of IPsec for VoIP in a small test LAN using a bare PC softphone The results show that 1) for incoming packets, the difference between the processing time...
This paper introduced a new IP-storage protocol named Ata over Ethernet, then modeled and analyzed the performance of it by comparing with iSCSI. To prove the theoretical analysis, we tested both AoE and iSCSI under various system configurations, i.e., under different network layer parameters and physical layer parameters. We found that both of them can affect AoE performance at different levels....
Mobility protocols are designed to support handover between different wireless networks. Many of them suffer problems such as high handover latency, high packet overhead, high packet loss during handoff, lack of application transparency, etc. To remove these problems, we proposed a network layer based mobility protocol framework, SEamless MObility using shim6 (SEMO6), for host mobility. It is based...
IP multimedia subsystems (IMS) is using session initiation protocol (SIP) as signalling protocol. SIP is becoming computing intensive and hence the ability of entry and exit proxies to process SIP messages has great impact on the overall performance of the IMS core network. This paper shows that the flow of SIP messages during handover process in the IMS core network complies with the well known central...
In the modern era the uses of wireless devices are becoming ubiquitous and these networks have become an increasingly important part of global communication architecture. Most of the wireless networks have fixed infrastructure and the need for mobile wireless networks are growing rapidly, which requires higher data rates. Due to high data rate in wireless networks the TCP performance has a broad and...
