KAJIAN PERBANDINGAN PERFORMANSI ROUTING PROTOCOL RIPNG, OSPFV3 DAN EIGRPV6 PADA JARINGAN IPV6

The main purpose of IP next generation version 6 or called IPv6 is to meet the needs of IP addresses for the long term. With the presence of IPv6 it is also necessary routing protocol that supports IPv6 network. Routing protocols work to connect between networks, and choose paths or routes to reach other networks. There are three types of routing protocols that already support IPv6 services. Among other types of distance vector (RIPng), link-state (OSPFv3) and hybrid (EIGRPv6). This final project is designed to know the performance of the three types of routing protocols on IPv6 network. Testing is done by analyzing routing update process, ICMPv6 packet analysis and testing by sending Real-time Transport Protocol (RTP) packet in the form of audio video stream sent via server and accessed through client. In the simulation and analysis results using GNS3 (Graphic Network Simulator 3) and wireshark found that the OSPFv3 performance testing is better than EIGRPv6 and RIPng when performing routing updates or when link down occurs. Then the data analysis of test results with the delivery of Real-time Transport Protocol package so that it can be concluded that OSPFv3 algorithm better than EIGRPv6 and RIPng in terms of delay, packet loss, throughput and jitter.

Deploying IPv4-only Connectivity across Local IPv6-only Access Networks

ABSTRACTThis document specifies a new mechanism called D4across6, which stands for Deploying IPv4-only Connectivity across Local IPv6-only Access Networks. This protocol could be used to ease the process of transition to IPv6 protocol, particularly in the ISPs’ access networks. This protocol allows legacy IPv4-only devices to communicate with IPv4-only content providers over an IPv6-only infrastructure. The main part is an application level tunnelling protocol that allows IPv6-only ISPs to provide IPv4 connectivity in addition to IPv6 connectivity across IPv6-only access networks. It carries IPv4 packets and routing information of the IPv4 protocol over an IPv6-only network infrastructure. The features of the proposed protocol are: offers IPv4 connectivity across IPv6-only access networks, stateless operation, cost-effective solution, and requires simple and automatic configuration at customers’ hosts. D4across6 requires installing an application and a pseudo network driver at the IPv4-only hosts in order to allow them to communicate with IPv4-only content providers. The configured IPv4-only hosts will be able to auto-detect the ISP available connectivity in the following precedence: native IPv6, IPv4-in-IPv6, or no IPv4 connectivity. The protocol does not require replacing or upgrading customer edges. Thus, a minimal cost is expected in providing IPv4-only connectivity after successfully deploying of IPv6 service to subscribers. The simulation analysis showed that the performance metrics of D4across6 is pretty near to those of native IPv6 and IPv4 protocols. Additionally, the performance of D4across6 is better than that of all (A+P), DS-Lite and 4rd protocols.

Advanced dynamic IPv6 activation-based defence for IPv6 router advertisement flooding (DoS) attack

IPv6 router advertisement (RA) flooding is an example of a DoS attack. It leads to denial of service attack on entire local area network. As a result, all systems connected to that LAN get frozen and unresponsive. Hence, it is very important to protect our LANs from IPv6 RA flood attack. In this paper, we describe IPv6 RA flood attack in virtual LAN using KALI Linux. We show its effects on the victim's computer. We propose a new approach to defend from IPv6 RA flooding DoS attack by dynamic IPv6 activation. Such a system would detect the attack and raise a warning alarm. It deactivates IPv6 temporarily. When the host recovers from the attack, the proposed system reactivates IPv6 again. So by using this approach users can use both IPv6 and IPv4 services even under attack. We have also provided pseudo code and experimental results in this paper.

A Scalability and Performance Analysis of Preauthentication Algorithms for Wireless Networks

Secure wireless networks strive to maintain continuity of service while its subscribers move among fixed access points. In vehicular networks, handovers may happen rapidly, and the service continuity from Mobile IPv6 services provides a distinct advantage. Unfortunately, the requirement to authenticate each subscriber as it is passed to each new access point results in a time delay that translates into breaks in connectivity and undesirable retransmission of packets. To provide continuity of service in secure wireless networks, preauthentication algorithms have been proposed that accomplish the authentication process before the user is officially serviced by the access point. We are particularly interested in preauthentication algorithms that efficiently provide preauthentication to likely “next” access points. This paper compares the performance of three different preauthentication algorithms integrated into Fast Mobile IPv6 using signals from the IEEE 802.21 media independent handover framework. Through analysis and simulation, we compare different alternative preauthentication options using four measures of effectiveness as the basis of comparison.

A New Scheme for a Mobile Node Seamless Mobility in Mixed Networks IPv4 and IPv6 Traversing NAT Routers

In the mobility environment, the interoperability between IPv4 and IPv6 networks is required due to the incompatibility that occurred in the headers of both IPv4 and IPv6 protocols. It is probable that a Mobile Node (MN) moves out of its home agent's domain towards a different IP domain IPv4/IPv6. This paper proposes a new scheme for mobile nodes that are connected with the home agent which is basically located behind Network Address Translation (NAT) to allow roaming of the MN throughout the IPv6 domains. MN would be able to communicate with its home agent despite its roaming throughout the IPv6 domain. Therefore, the proposed scheme is based on Teredo tunnel that allows clients behind NAT to utilize and get IPv6 services.

Configuring Hosts to Auto-detect (IPv6, IPv6-in-IPv4, or IPv4) Network Connectivity

This document specifies a new IPv6 deployment protocol called CHANC, which stands for Configuring Hosts to Auto-detect (IPv6, IPv6-in-IPv4, or IPv4) Network Connectivity. The main part is an application level tunneling protocol that allows Internet Service Providers (ISPs) to rapidly start deploying IPv6 service to their subscribers whom connected to the Internet via IPv4-only access networks. It carries IPv6 packets over HTTP protocol to be transmitted across IPv4-only network infrastructure. The key aspects of this protocol are: offers IPv6 connectivity via IPv4-only access networks, stateless operation, economical solution, assures most firewall traversal, and requires simple installation and automatic configuration at customers’ hosts. All data packets and routing information of the IPv6 protocol will be carried over the IPv4 network infrastructure. A simple application and a pseudo network driver must be installed at the end-user’s hosts to make them able to work with this protocol. Such hosts will be able to auto-detect the ISP available connectivity in the following precedence: native IPv6, IPv6-in-IPv4, or no IPv6 connectivity. Because the protocol does not require changing or upgrading customer edges, a minimal cost in the deployment to IPv6 service should be expected. The simulation analysis showed that the performance of CHANC is pretty near to those of native IPv6, 6rd, and IPv4 protocols. Also, the performance of CHANC is much better than that of D6across4 protocol.

Implementation of IPv6 services over a GMPLS-based IP/optical network

In recent days, there has been considerable interest in deploying IPv6-based services. Trial and commercial IPv6 services offering has already begun, especially in Japan, Korea, China, and other parts of the world. At the same time, many service providers have embraced MPLS as the enabler for the required multiservice capabilities of their next-generation packet networks. Also, the widespread deployment of DWDM-based optical transport systems in the core network to satisfy the tremendous need and increase in capacity demand has led network planners to reconsider traditional approaches to provisioning and network restoration, and plan integration of the optical layer into the MPLS infrastructure according to the emerging GMPLS technology. The purpose of this article is to discuss next-generation network architecture evolution and present a detailed architecture for transport of emerging IPv6 services and applications over next-generation GMPLS multiservice backbone networks. This article also presents an implementation and demonstration of this technique for IPv6 transport over a GMPLS backbone network as well as interoperability verification of IPv6 and GMPLS using a GMPLS network testbed.

Migrating to IPv6: The Problem of the Applications

After several years of studies and experiments, the day of the new IP, identified as version 6, are coming; the growing pressure is mostly due to address shortage (especially in Far East countries), the imminent introduction of new 3G mobile devices, and routing scalability problems. While most of the modern operating systems and network devices (routers) are already IPv6-capable, one of the biggest problems is related to the huge amount of work involving application migration. This paper studies some issues related to the migration of applications to IPv6: (i) how difficult the porting is and (ii) how to make an application IPv6-compatible when its source code is not available. This paper presents solutions to the latter problem that “retrofit” off-the-shelf server applications. Such solutions can also be deployed in response to the pressing demand to promptly make native IPv6 service available to IPv6-enabled clients.

Deployment and test of IPv6 services in the VTHD network

This article presents the deployment and test of IPv6 services in the very high broadband IP/WDM (VTHD) [L. Thual, 2003] network for new-generation Internet applications. The VTHD project is partially funded by the French government through the French Research Network for Telecom (RNRT). VTHD supports both IPv4 and IPv6 services, and interconnects research centers and institutions in France. It has a public autonomous system number (AS20603) and a public IPv6 subnet. It is connected to the IPv6 global network via open transit (France Telecom's international IP service for ISPs). VTHD in France compares with Internet2 in the United States. This article focuses on the implementation of the IPv6 service, IPv6 performance (in the context of a high-speed network), the advantages of given technologies, and problems encountered. The following items are developed: VTHD architecture, IPv6 address space and aggregation, transition mechanisms, routing protocols, network test performance, IPSec test performance, naming (DNS), and network management.

A scenario-based review of IPv6 transition tools

Momentum for IPv6 transition is on the rise, and many transition tools and techniques are available to ISPs, enterprise networks, and unmanaged networks. From a transitioning perspective, the ISP environment is interesting because the operators migration approaches will define, quite strictly, the extent of IPv6 services that their customers receive. As such, the ISPs (scalable) migration decisions have direct knock-on effects for customers. In the future, customers might require ISPs to offer value-added lPv6 services that not only have performance-based restrictions, but security and mobility considerations, as well.
