Neighbor discovery protocol (NDP) is the core protocol of Internet protocol version 6 (IPv6) suite. The motive behind NDP is to replace address resolution protocol (ARP), router discovery, and redirect functions in Internet protocol version 4. NDP is known as the stateless protocol as it is utilized by the IPv6 nodes to determine joined hosts as well as routers in an IPv6 network without the need...
This paper first proposes decentralized content delivery scheme using distributed in-network caching and its performance is compared to that of centralized content delivery scheme. In addition, a persistent request-routing system (RRS) is introduced to redirect all client requests for the same content to a particular content router once the router is chosen from the first request. Therefore, such...
IPv6 has been developed to deal with the increase in number of hosts in the Internet. IPv6 address can be assigned to any network devices. IPv6 provides new function called SLAAC (Stateless Address Auto Configuration). SLAAC is a significant feature for host itself generating and configuring own addresses to enable communication. But this feature has drawbacks in term of security and management of...
In this paper, we report our development experience and experimentation studies of two multicast routing schemes for the Internet, namely, PIM-SSM and GCMR. We detail their implementation over the Quagga open source routing suite, as well as their experimentation tests over a large-scale topology that reproduces the Internet characteristics.
Originally defined in the 90s, multicast is nowadays (re)gaining interest given the increasing popularity of multimedia streaming/content traffic and the explosion of cloud services. In fact, multicast yields bandwidth savings complementing cached content distribution techniques and its potential benefits have been verified by studies several times since then (see e.g. [1]). By multicast routing,...
Data delivery across a multi-hop low-power and lossy networks (LLNs) is a challenging task: devices participating in such a network have strictly limited computational power and storage, and the communication channels are of low capacity, time-varying and with high loss rates. Consequently, routing protocols finding paths through such a network must be frugal in their control traffic and state requirements,...
The scale of the Internet and the load growth, result in the insufficiency of address size and a sharp increase of router storage and exchange information, so that IPv6 can be a considerable development, and will eventually replace the IPv4. This paper describes the principle of IPv6 routing technology and analyzes the main routing technique, introduces IPv6 routing table and packet-transfer technology,...
This paper presents the design and evaluation of IPv4/IPv6 translator which supports co-existence of IPv4 based and IPv6 based fieldbus protocols. Although IPv6 is the subsequent version of IPv4, there is no compatibility between them. A number of fieldbus protocols work on IP, but they are designed on IPv4. Moreover, IPv6 based fieldbus will co-exist with IPv4 based fieldbus. Therefore, we should...
Delay Tolerant Networks (DTNs) are a class of net-works characterized by intermittent connectivity, long delays and non-contemporaneous end to end paths. Internet protocols will not work in these environments and special protocols must be developed to serve them. Often nodes in these networks are battery operated and have limited shared band-width so network transmissions must be kept to a minimum...
We claim that the slow deployment of IPv6 seen so far is related with the complete decoupling with IPv4 regarding to routing and addressing. In this paper we propose Integrated Routing and Addressing (InRA), a new solution to allow IPv6 to integrate with IPv4 routing and addressing in order to decrease management cost during the coexistence period, and speed up IPv6 deployment. Addressing and routing...
With the ever increasing demand of multimedia traffic on the Internet, the interest in deploying multicast for distribution of these contents have increased. One hurdle however in this regard is quantifying the multicast protocol performance. Many efforts have been put into defining multicast metrics for evaluating protocol performance. In this paper we define a metric which will provide a reasonable...
The large IPv6 address space enables the study on network addresses in a network environment, which ensures the construction of a secured and trusted China next generation Internet (CNGI), it is a tested for next generation Internet (NGI) applications. This paper describes two of the major transition technology and discusses their applicability and uses. The intra-site automatic tunnel addressing...
Current service discovery protocols have a static protocol behavior with respect to their architecture and their message dissemination strategies. Protocols for ad-hoc networks use optimized flooding techniques, approaches for the Internet are server-centric. Wireless mesh networks are much more flexible in their way of connecting nodes as they can consist of a backbone of mesh routers and a number...
With the ever increasing demand of multimedia traffic on the Internet the interest in deploying multicast has increased. One hurdle in this regard is quantifying the multicast protocol performance. Many efforts have been put into defining multicast metrics for evaluating protocol performance. In this paper we identified metrics that will provide reasonable measure of protocol's efficiency. The metric...
End-system multicasting (ESM) is a promising application-layer scheme that has been recently proposed for implementing multicast routing in the application layer as a practical alternative to the IP multicasting. Moreover, ESM is an efficient application layer solution where all the multicast functionality is shifted to the end users. However, the limitation in bandwidth and the fact that the message...
Multicast patching is one of the techniques to reduce the burden of a video on demand (VOD) server. A novel patching mechanism by using multi-homing has placed its logical channel into another network interface of a client terminal. The performance of proposed patching mechanism is presented via numerical analysis. In summary, our proposed scheme modifies multicast patching model using extended client...
In order to communicate among themselves and with the devices on the Internet, a Mobile Ad-hoc NETwork (MANET) node needs to configure its interface(s) with IP address(es). MANET is a multi-hop network often consisting of mobile devices such as mobile phones, PDAs, laptops with wireless interface(s). Due to some of the MANET inherent characteristics such as mobility, multi-hop and ad hoc, manual configuration...
Multicast communication in the internet has been growing rapidly over the last few years. Internet applications transmit data from one sender to many receivers, In Multicast protocols while packet broadcasts to a group of receivers the total numbers of packets swamped in a network decrease. Multicast communication reduces both the time it takes to send data to a large no of receivers and the amount...
The primary function of the Internet protocol (IP) is delivering datagram's across an internetwork and addressing is one of the most important functions of IP. Communication between hosts over an internetwork is accomplished using IP addresses, but the actual communication over a physical network takes place using physical addresses. The mapping of IP addresses to physical addresses is done through...
IPv4 is the network protocol of the current Internet, defined by the Internet Engineering Task Force, IETF. This paper describes the IETF's successor to IPv4, known as IPv6. It examines why we may now need this, and describes some implications of changing the Internet to use IPv6.
