Scalable Balanced Pipelined IPv6 Lookup Algorithm

One of the most critical router’s functions is the IP lookup. For each incoming IP packet, IP lookup determines the output port to which the packet should be forwarded. IPv6 addresses are envisioned to replace IPv4 addresses because the IPv4 address space is exhausted. Therefore, modern IP routers need to support IPv6 lookup. Most of the existing IP lookup algorithms are adjusted for the IPv4 lookup, but not for the IPv6 lookup. Scalability represents the main problem in the existing IP lookup algorithms because the IPv6 address space is much larger than the IPv4 address space due to longer IPv6 addresses. In this paper, we propose a novel IPv6 lookup algorithm that supports very large IPv6 lookup tables and achieves high IP lookup throughput.

Empirical Analysis of IPv4 and IPv6 Networks through Dual-Stack Sites

IPv6 is the most recent version of the Internet Protocol (IP), which can solve the problem of IPv4 address exhaustion and allow the growth of the Internet (particularly in the era of the Internet of Things). IPv6 networks have been deployed for more than a decade, and the deployment is still growing every year. This empirical study was conducted from the perspective of end users to evaluate IPv6 and IPv4 performance by sending probing traffic to 1792 dual-stack sites around the world. Connectivity, packet loss, hop count, round-trip time (RTT), and throughput were used as performance metrics. The results show that, compared with IPv4, IPv6 has better connectivity, lower packet loss, and similar hop count. However, compared with IPv4, it has higher latency and lower throughput. We compared our results with previous studies conducted in 2004, 2007, and 2014 to investigate the improvement of IPv6 networks. The results of the past 16 years have shown that the connectivity of IPv6 has increased by 1–4%, and the IPv6 RTT (194.85 ms) has been greatly reduced, but it is still longer than IPv4 (163.72 ms). The throughput of IPv6 is still lower than that of IPv4.

survey on the performance analysis of IPv6 transition technologies

As the public IPv4 address space has already been depleted, the full deployment of IPv6 became indispensable, especially for service providers, as it offers a sufficient address pool. However, the ongoing IPv6 transition seems to be a lengthy task because of the numerous challenges it faces. Therefore, it is expected that IPv4 and IPv6 will coexist for a long time. Consequently, many transition technologies have been developed for this purpose. Several research papers have conducted performance analysis for a number of these transition technologies and even compared them based on some measuring metrics like RTT, throughput, jitter, packet loss, and so on. This paper reviews the results of these papers, discusses their findings, and gives some guidelines fora feasible benchmarking methodology.

Routing the Messages to Grid Channel Based Model in Wireless Mesh Networks

Earlier the work has analyzed and implemented through IPV4 based traffic. The researchers have address the source IPv4 based routing in MRMC method. The router configures with a standard IPV4 based network extracts the source IPV4 address from the packet Header. This paper has been defined the network topology which was work on IPV6 protocol and it may also support IPV4 protocol. This paper implements the equalization that takes observation of channel state. The stations collect channel state information to their neighboring node, later on it was transfer to Gateway. The collected information was only possible through equalization method. In general, the equalization divided into two ways, per symbol and Sequence based which are according to receiver Theory. We are using sequence based theory under equalization that take data from maximum likelihood neighbors. We were used proposed Hybrid that take the existing method and combine with dynamic channel method. The proposed model avoids the multipath propagation problem and that problem only arise when we changes the channel from one wavelength to another wavelength. This paper showed proposed results that would be analysis the position of the packets in cluster head (CH). The router is taking as the cluster head which is being deployed on the number of nodes and these nodes randomly moves from one location to another. The MATLAB Simulator has been used in this research paper that helps to solve the complex mathematical equation. Network Simulator (NS2) has used to implement the Network Model.

Penerapan IPV4 dan IPV6 pada Jaringan yang Terhubung

The computer networks is growing rapidly along with the increasing of computer's users. The large number of computers or hosts connected in a network will make it difficult to manage, so it needs a unique identity on each host connected to a computer network. The IP address technology is a solution to overcome the complexity of local and global computer networks. The IPv4 is the IP addressing technology for every host connected in a network, but the growth of computer users hence the availability of IPv4 address becomes very limited, so the IPv6 technology is developed. To avoid IP address conflicts around the world, the IP address allocation and distribution blocks for each Internet service providers worldwide is arranged by RFC (Request for Comments) standards. This journal describes the IPv4 and IPv6 addresses technology implementation on the host connected in a computer network. It is expected that with this journal both IP addresses generation can be applied in a computer network appropriately.Keywords:ip address, ipv4, ipv6

Analysis Tunneling IPv4 and IPv6 on VoIP Network

Using of IP addresses is currently still using IPv4. Meanwhile, the availability of the IPv4 address is gradually diminishes. IPv4 has a limited address capacity. IPv6 was developed with a capacity greater than IPv4. Connect between IPv4 and IPv6 without having to interfere with the existing infrastructure. So, methods like tunneling are needed. Tunneling builds a way that IPv4 and IPv6 can communicate. 6to4 tuning makes IPv6 able to communicate with IPv4 over IPv4 infrastructure. Real time communication is needed by internet users to be able to connect to each other. One of the real time communications is VoIP. To find out the quality of tunneling implemented on a VoIP network, it will analyze QoS such as delay, packet loss, and jitter. Delay obtained is 20,01ms for IPv4, 19,99ms for IPv6 and 20,03ms for 6to4. Packet loss obtained 0,01% for IPv4, IPv6 0,01% and 6to4 0,08%. The obtained jitter is 7,96ms for IPv4, IPv6 7.39ms, and 8,48 for 6to4. The test results show that using IPv6 gets a better QoS value than using IPv4 and 6to4 tunneling. The results using 6to4 tunneling obtained the highest QoS value between IPv4 and IPv6. Implementation using 6to4 tunneling results in high results because, IPv6 packets that are sent are wrapped into the IPv4 form to get through the IPv4 infrastructure.

IPv6-Based IoT Smart Cities

In the process of Internet evolution, the transition from IPv4 to IPv6 has become inevitable and fairly urgent. IANA (Internet Assigned Numbers Authority) has finally exhausted the global IPv4 address space, which leaves the community no choice but pushes forward the IPv6 transition process. IPv4 and IPv6 networks both will exist during the transition period, while the two are not compatible in nature. Therefore, it is indispensable to maintain the availability, as well as to provide the inter-communication ability of IPv4 and IPv6. Years ago, a series of transition techniques were actually proposed. However, because of their technical immatureness, they failed to cover the solution space well. Some of these techniques were even obsoleted by IETF due to their flaws.
