IPv6 is an ultimate solution to the Internet address exhaustion. It is believed, the protocol will be requested by not only human but also everything on the earth surface. Furthermore, the improvement on the protocol is important to achieve IP packets transmission efficiently. Processing technology has been improved to become very fast packet processing both in host as well as intermediate systems...
IPv6 has become popular now-a-days among the ISPs, organization and end users because of its magnificent features and due to the limitation of IPv4. The migration from IPv4 to IPv6 is mandatory due to the address scarcity and security vulnerabilities of IPv4. But the deployment of IPv6 is far beyond satisfactory level in Bangladesh. So, a smooth as well as effective transition mechanism is needed...
IPv6 is the next-generation Internet Protocol (IP) which designed to replace the current IPv4.The designed protocol is to manage the problem of insufficient IP address for online users. IPv6 is new technology, thus it is not matured and does it suits to the real online applications in any applied network. This paper evaluates the performance of End-to-End (E2E) IPv6 over wired and Wi-Fi broadband...
IPv4 and IPv6 protocol are incompatible due to their different header structure; therefore no direct communication exists between them. For the two protocol to coexist, IETF proposed three possible solutions; Dual Stack, translation and tunnelling. This paper evaluates the performance of tunnelling and dual stack as they are the most deployed techniques. 6to4, ISATAP and 6RD were the three automatic...
6in4 is the IPv4 to IPv6 migration technique that uses tunneling to encapsulate IPv6 packets over configured IPv4 communication links. This paper attempts to evaluate and compare performance parameters like Throughput, IP End-to-End Delay and Response Time of different applications running on the internet in IPv4, IPv6 and 6in4 manual tunneling environments. The applications that we are modeling are...
IP Next Generation (IPng) or IPv6 engineered by IETF is the successor of IPv4, the contemporary version of Internet Protocol. IPv6 is designed to solve the long term performance, reliability and scalability problems of IPv4. Although IPv6 implementation is yet to attain a maturity level, its success will ultimately depend on its implementation in a broader perspective. The IPv6 network migration is...
Wireless Embedded Internet aims for efficient connectivity for embedded devices to the internet. This requires the embedded devices to run IPv6 protocol. The 6LoWPAN was introduced to enable IPv6 internet connectivity for WPAN. Enabling IPv6 in wireless, small size, low power, low rate, limited memory and limited computation capabilities devices, with a limited frame size, is not directly applicable...
Future of IP addressing is totally dependent on IPv6 rather than IPv4 to assure the Quality of Service (QoS) requirements and IPv6 have noteworthy advantages over present IPv4. Presently, the conversion mechanisms in Dual Stack Transition Mechanism (DSTM) is taking bit more time, which hampers the overall performance of the network. In this paper we have reduced the time delay of data packets transmission...
IPSec (IP Security) is a robust technique for securing communications over the Internet. Due to security algorithms used, transferring data using IPSec is known to be significantly slow. In this paper using a test bed environment for a site to site IPSec, we present new results on performance of IPSec for both IPv4 and IPv6 using Fedora 15 operating system and wireless network. Compared to open system,...
Extending IPv6 to IEEE 802.15.4-based Low power Wireless Personal Area Networks requires efficient header compression mechanisms to adapt to their limited bandwidth, memory and energy constraints. This paper presents an experimental evaluation of an improved header compression scheme which provides better compression of IPv6 multicast addresses and UDP port numbers compared to existing mechanisms...
Based on the migration mechanism from IPv4 to IPv6, the performance of three kinds of mechanism options, double-stack protocol, ISATAP tunneling and 6to4 tunneling technique are analyzed and tested. The result shows there are some performance advantages on double stack protocol mechanism IPv6 network than IPv4, IPv6 ISATAP tunnel and IPv6 6to4 tunnel network.
Memory efficiency with compact data structures for Internet Protocol (IP) lookup has recently regained much interest in the research community. In this paper, we revisit the classic trie-based approach for solving the longest prefix matching (LPM) problem used in IP lookup. In particular, we target our solutions for a class of large and sparsely-distributed routing tables, such as those potentially...
With the growing speed of computer networks, the core routers have to increase performance of longest prefix match (LPM) operation on IP address. While existing LPM algorithms are able to achieve high throughput for IPv4 addresses, the IPv6 processing speed is limited. In this paper we propose a new Hast-Tree Bitmap algorithm for fast longest prefix match for both IPv4 and IPv6 networks. The algorithm...
Transmission Control Protocol (TCP) was considered unsuitable for Low power and Lossy Networks (LLNs) due to the characteristics LLN devices (low computing power, strong energy constraint, etc.) and to the absence of IP layer on the network layer. Recently, the IPv6 over Low power Wireless Personal Area Networks (6LoWPANs) has been introduced as an adaptation layer for IPv6 over LLNs. Thanks to the...
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...
Networks are at the core of global communication. The impact network changes have on network performance has been of concern to researchers. In various configurations, network performance has been evaluated using many methods. The paper presents findings of a network performance evaluation where multiple hardware routers were implemented on a test-bed and performance difference between the two versions...
PRIME (PoweRline Intelligent Metering Evolution) is one of the prominent upcoming powerline communication technologies, targeted for use in smart metering applications. The PRIME PHY / MAC specifications are open, publicly available and are developed by the PRIME Alliance, an industry consortium that includes utilities, meter vendors and semiconductor suppliers. PRIME employs OFDM modulation in the...
This paper presents an idea in the context of multicasting: it is to manage QoS with a certain level of hazard. The Xcast and IPv6 are used in the context of IPTV which is a contestable choice since the number of user could be high regarding the size of the packet header. In large IPTV network, even an IPTV stream with a small number of subscribers could have hundreds of them. Moreover if Xcast stream...
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...
The concept of transition from IPv4/IPv6 network is currently being extensively studied to gain high level compatibility for easy, independent deployment ofIPv6. The transition between IPv4 and IPv6 internet will be a very long process as they are completely incompatible two protocols. IPv6 offers various features including Larger addressing capacity and capabilities, QoS control, encryption and decryption,...
