Conceptual model for comparison of IPv6 ISPs based on IPv4 traffic profiles

The slow adoption of IPv6 protocol by organizations has led to internet service providers (ISP) investing minimal resources in setting up IPv6 Internet connectivity, ultimately resulting in sub optimally tuned IPv6 Internet routing fabric. The altogether different IPv6 packet header with more bits for the IP address, no header checksum, and no intermediate fragmentation features, are expected to give a palpably different experience to the users. With different levels of expertise and different connectivity links to the Internet, available with different ISPs, responses of the destined networks may also vary for each ISP. Therefore, it is worth to investigate ISP wise IPv6 Internet responses from an organization user’s point of view. In this paper, we present a research methodology to estimate IPv6 responses to the users of an organization for destinations present in current IPv4 traffic profile, without actually accessing the IPv6 network. We use publicly available centre for applied internet data analysis (CAIDA) IPv6 topology and autonomous systems (AS) links datasets to analyse and infer the intermediate AS level responses, for estimating responses between source and destination networks. As a case study, we take three Indian ISPs and apply the methodology to compare ISP wise responses for a network of about 2000 nodes. The results of the same are presented in this paper. We conclude that considering all other factors to be the same, the best possible quality of experience (QoE) for the Internet users of the organization, can be achieved by smart selection of the IPv6 ISP.

Performance Evaluation of IPv6 Network for Real-Time Applications using IS-ISv6 Routing Protocol on Riverbed Modeler

Abstract In this new era of the internet world, long-distance effective communication depends on the choice of IP and routing protocols. Various decisions are considered to find the optimal routing protocol for network deployment. The routing protocol which gives the best performance on some objective parameters (convergence, jitter, delay, bandwidth utilization, throughput, etc.) have opted for deployment. Also, according to the network and traffic demands, these routing protocols decide the performance of real-time applications. As IPv4 addresses are exhausting, moving to IPv6 is expected and challenging. This next-generation internet protocol brings new modified routing protocols which are enhanced versions of the existing ones. In this paper, the IS-ISv6 routing protocol is considered as it is scalable, more flexible towards IPv6 addresses, robust, support larger areas and can give better performance than other existing routing protocols. The IPv6 network is configured to measure the performance of real-time applications-voice and video using IS-ISv6 routing protocol and the network is simulated on riverbed modeler academic edition 17.5. The main objective of this paper is to find the performance of IS-ISv6 for routing the traffic. For both, the applications, the traffic sent and received are present to calculate the maximum throughput of the network. The results are also present for end-to- end delay and packet delay variations for voice and video applications. The simulation results for IPv6 traffic dropped and jitter in voice are also obtained in this paper. This research paper finds that the IS-ISv6 routing protocol enhances the throughput of video applications in the IPv6 network. However, the average performance for voice application is achieved with less end-to-end delay and packet delay variations. Thus IS-ISv6 routing protocol can be used efficiently for high-performance real-time application networks.

Design of a new wireless data acquisition system for civil structural monitoring

Traditional civil structure wired monitoring systems suffer complicated wiring, high cost, poor flexibility, and available wireless sensors network (WSN)-based wireless monitoring systems are inconvenient to access the internet. In this paper, based on the 6LoWPAN means: IPv6 low-power wireless personal area network WSN, a new wireless data acquisition system is proposed for structural monitoring applications, which consists of data acquisition nodes, a border node and a remote monitoring centre. The hardware design of the wireless data acquisition system is based on the CC2538 wireless transceiver, and inertial sensors and temperature and humidity sensors are integrated. Based on the Contiki-3.0 embedded operating system, the embedded application software of 6LoWPAN data acquisition nodes and border router nodes are designed.

A Hybrid Transition for IPv4-IPv6 Co-existence in Small Size Organization

Internet Protocol version 6 (IPv6) is the current generation Internet protocol developed by the Internet Engineering Task Force (IETF) to handle the shortage of IP addresses in IPV4. The transition from IPv4 to IPv6 is gradually being done not happening as anticipated. It is unavoidable to have both IPv4 and IPv6 networks during the transition period, but unfortunately they are not compatible in nature. It is essential to maintain the IPv4 and IPv6 coexistence. The inter-communication ability of IPv4 and IPv6 is the dire need of network community. Many transition techniques are proposed in the recent years. This paper discussed the key difficulties in IPv4-IPv6 transition, and introduced the hybrid approach for coexistence of IPv4 and IPv6. It hybrid the advantages of weightage and tunneling translation techniques for providing inter-communication ability of IPv4 and IPv6. The proposed algorithm has been simulated and the performance metrics; transmission latency, throughput, jitter and delay have been analyzed from end to end host, through various scenarios includes IPv4 only, IPv6 Only, Dual stack, GRE tunneling. The performance of the proposed algorithm is analyzed and the future scope is discussed.

Affordable Broadband with Software Defined IPv6 Network for Developing Rural Communities

The software defined networking (SDN) paradigm with enhanced features of IPv6 offers flexible network management and better network visibility for enhancing overall network performance, network manageability, and security. Thus, along with the IPv6 network deployment worldwide, SDN migration has emerged worldwide, but network service providers suffer from different issues when migrating their existing legacy network into operable SDN and IPv6 enabled networks. In this paper, we investigate the affordability of broadband network services for the rural communities in the context of information and communication technology (ICT) infrastructure deployment throughout Nepal. During the phase of network transformation, it will be more challenging for the service providers of Nepal to have a proper choice of technologies to expand the network while considering the proper policy formulation, affordability, need of skilled human resources, deployment cost, and many other aspects. We also present the service provider affordability via energy optimization in software defined IPv6 network (SoDIP6) implementation that contributes to a reduction in organizational operational expenditure (OpEX). We perform an experimental analysis over an SoDIP6 network testbed and present a comparison of the annual energy and OpEX savings for network service providers. Our empirical analysis shows that an energy saving of 31.50% on switches and 55.44% on links can be achieved with an SoDIP6 network compared to a network with legacy devices and network management. Optimization on service provider network operational cost leads to sustainability and affordable services to both customers and service providers

IETF 6TiSCH: A Tutorial

The IETF IPv6 over the TSCH mode of IEEE802.15.4e (6TiSCH) working group has standardized a set of protocols to enable low power industrial-grade IPv6 networks. 6TiSCH proposes a protocol stack rooted in the Time Slotted Channel Hopping (TSCH) mode of the IEEE802.15.4-2015 standard, supports multi-hop topologies with the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) routing protocol, and is IPv6-ready through 6LoWPAN. 6TiSCH has defined the missing control plane protocols to match link-layer resources to the routing topology and application communication needs. 6TiSCH has also defined a secure light-weight join processes combining link-layer security features (through Counter with CBC-MAC (CCM*)) with a secure joining procedure using the Constrained Application Protocol (CoAP). This tutorial provides a comprehensive overview of the 6TiSCH architecture and protocol suite, including the 6TiSCH Operation Sublayer (6top), the 6top Protocol (6P), and how it uses 6LoWPAN, IP-in-IP encapsulation, and RPL. This document is meant to be used both as a primer, and as a reference. It is tailored to the advanced researcher and engineer implementing and building upon IETF 6TiSCH specifications.

Address Autoconfiguration in IPv6 Networks: Challenges and Countermeasures

The demand for internet and its applications has eventually led to the depletion of the dominant IPv4 addresses. This has resulted in the inevitable need for the next generation Internet Protocol IPv6, which contains an enormous pool of IP addresses. Address Autoconfiguration, a remarkable feature of IPv6 enables a node connected in the network to automatically configure an IP address for its interface and instantly participate in network communications. The Internet Engineering Task Force (IETF) has classified autoconfiguration into Stateless and Stateful mechanisms. Several IPv6 protocols have been employed to achieve autoconfiguration of networks. However, in addition to the excellent competence of this feature, autoconfiguration certainly suffers in terms of security and optimization. This paper attempts to enlighten the need and merits of Address Autoconfiguration and finally highlights the challenges, open issues and countermeasures involved in achieving this in real time environment.

Novel Approach for Management of Automated IPv6 Network Simulation

The complexity of network technologies and the variety of their equipment and settings make them difficult to evaluate, to simulate, and to deploy. IPv4 to IPv6 transition mechanisms are one of the modern issues recently exposed with the emergence of technologies such as Internet of Things, which have practically consumed the existing IPv4 address pools and therefore require a transition to new IPv6 protocol to meet the need. Simulation plays an important role in the modeling, optimization, and evaluation of IPv4–IPv6 transition mechanisms. Through simulation several factors can be studied before the deployment on real environment, such as the transition mechanism, the number of users, the routing protocols, and the transported applications. This paper describes how state-of-the-art network automation can contribute to the development of a new approach for automating the simulation of IPv4 to IPv6 transition techniques based on an interactive graphical platform. The proposed approach can be interfaced with a variety of scientific research simulators guaranteeing the users a reduction in project implementation delay and error rate, the approach can also ensure a simplification of simulator use.

Kompasrasi Unjuk Kerja Aplikasi File Transfer Protocol dengan MPLS pada Jaringan IPv4 dan IPv6

The number of devices using the IPv4 protocol has greatly increased. The IPv4 protocol is out of date because it no longer has the ability to support so many devices. The development of IPv6 as a future protocol to replace IPv4 is still ongoing. With an address space of 128 bits, IPv6 increases the number of available IP addresses. This study describes a simulation of Multi Protocol Label Swicthing (MPLS) network performance in a comparison between IPv4 and IPv6. The parameters observed were QoS, including delay, throughput and transfer time. The results of the analysis carried out showed that network differences have different effects on the parameter values of delay, throughput and transfer time. On MPLS IPv6 networks, the delay is smaller than MPLS IPv4 networks. For throughput and transfer time, IPv6 is also superior to IPv4.

Tracking the deployment of IPv6: Topology, routing and performance

We use historical BGP data and recent active measurements to analyze trends in the growth, structure, dynamics and performance of the evolving IPv6 Internet, and compare them to the evolution of IPv4. We find that the IPv6 network is maturing, albeit slowly, and notably IPv6 growth at the AS-level appears to have slowed after 2012. While most core Internet transit providers have deployed IPv6, edge networks are lagging. Early IPv6 network deployment was stronger in Europe and the Asia-Pacific region, than in North America. Current IPv6 network deployment still shows the same pattern. The IPv6 topology is characterized by a single dominant player – Hurricane Electric – which appears in a large fraction of IPv6 AS paths, and is more dominant in IPv6 than the most dominant player in IPv4. Routing dynamics in the IPv6 topology are largely similar to those in IPv4, and churn in both networks grows at the same rate as the underlying topologies. Our measurements suggest that performance over IPv6 paths is now largely comparable to (or better than) that over IPv4 paths.

Implementation of IPv6 Internet Service with MPLS Networks and MPLSL3VPN Service in IPv6 Networks

Exchanging the data packets seems as very challenging task due to exponential growth in network interface. Meanwhile, this increased interface makes use of next generation of internet protocol (IPv6) which will eventually replace the IPv4. Major issues in this replacement is the compatibility, both requires different set of routing protocols. Multi-Protocol Label Switching, a rapidly growing tele-communication infrastructure technology which works on special protocol suitable for both versions of Internet Protocol. MPLS uses the third OSI layer addressing coupled to second layer speed in switching and this paves the way for greater transfer of information, voice and video traffic. Virtual Private Network is the fastest growing technology for connecting the dispersed sites of same customer using the public network without any interference with other networks. This is an attractive technology to service providers because it enhances the flexibility for using variety of classes of services. This paper deals with the implementation of IPv6 networks for internet services using MPLS background which offers increased transfer in data, voice and video traffic. It also deals with, implementing MPLS based Virtual Private Network in IPv6 infrastructure using GNS3 simulator. This is done on behalf of the Border Gateway Protocol (BGP) which isolates the dispersed site in an Autonomous System (AS), connected to a public network.

SHIP: A Scalable High-Performance IPv6 Lookup Algorithm That Exploits Prefix Characteristics

Due to the emergence of new network applications, current IP lookup engines must support high bandwidth, low lookup latency, and the ongoing growth of IPv6 networks. However, the existing solutions are not designed to address jointly these three requirements. This paper introduces SHIP, an IPv6 lookup algorithm that exploits prefix characteristics to build a data structure designed to meet future application requirements. Based on the prefix length distribution and prefix density, prefixes are first clustered into groups sharing similar characteristics and then encoded in hybrid trie-trees. The resulting memory-efficient and scalable data structure can be stored in low-latency memories and allows the traversal process to be parallelized and pipelined in order to support high packet bandwidth in hardware. In addition, SHIP supports incremental updates. Evaluated on real and synthetic IPv6 prefix tables, SHIP has a logarithmic scaling factor in terms of the number of memory accesses and a linear memory consumption scaling. Compared with other well-known approaches, SHIP reduces the required amount of memory per prefix by 87%. When implemented on a state-of-the-art field-programmable gate array (FPGA), the proposed architecture can support processing 588 million packets per second.

Implementasi Voip Server Berbasis IPV6 Dengan Raspberry PI

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.
