Available in PDF, EPUB and Kindle. Book excerpt: This book examines multicast technology and will be a key text for undergraduate engineering students and master students in networks and telecoms. However, it will be equally useful for a wide range of professionals in this research field. Multicast routing was introduced with the advent of multiparty applications (for example, videoconferencing on the Internet) and collaborative work (for example, distributed simulations). It is related to the concept of group communication, a technique introduced to reduce communication costs. The various problems of multicast routing on the Internet are examined in detail. They include: group membership management, quality of service, reliability, safety, scalability and transport. Throughout the text, several protocols are introduced in order to analyze, compare and cover the various aspects of multicast routing.

Download or read book The Breadcrumb Forwarding Service and the Digital Fountain Rainbow written by Koichi Yano and published by . This book was released on 1999 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "If ubiquitously deployed, IP Multicast promises to provide an efficient datagram service for an arbitrary sending host to reach an arbitrary and dynamic set of destination hosts anywhere in the Internet. Unfortunately, two very difficult problems -- interdomain multicast routing and viable end-to-end multicast transport -- have yet to be solved and deployed satisfactorily. This paper proposes a new multicast service model called the Breadcrumb Forwarding Service (BCFS) synthesized from the EXPRESS service model and the network component of the Pragmatic Multicast protocol (PGM). Like EXPRESS, BCFS utilizes explicit-source group join and like PGM, enhances the network forwarding architecture with finer-granularity group control. To demonstrate the flexibility and efficacy of BCFS, we developed a novel reliable multicast transport protocol, Rainbow, for bulk data transfer built on top of BCFS. In this approach, each receiver runs an independent, window-based congestion control algorithm modeled after TCP, thereby affording 'TCP friendliness' while retaining the efficiency of IP Multicast. To enhance scalability and support asynchronous receiver behavior, we employ a Digital Fountain at the source. In this paper, we detail BCFS service model, describe how Rainbow builds on this service model and on the Digital Fountain abstraction, and evaluate the resulting system. Our simulation results show that Rainbow/BCFS performs well in a variety of configurations and is 'TCP friendly'."

This book was released on 2016 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective and efficient support for wireless data transfer is an essential requirement for future Internet design, as the number of wireless network users and devices, and the amount of traffic flowing through these devices have been steadily growing. This dissertation tackles several problems, and proposes algorithmic and protocol design solutions to better provide such support. The first problem is regarding the inefficiency of multicast in wireless networks: a transmission is considered a unicast despite the fact that multiple nearby nodes can receive the transmitted packet. Random network coding (RNC) is considered a cure for this problem, but related wireless network radio resources, such as transmit power, need to be optimally allocated to use RNC to its full advantage. A dynamic radio resource allocation framework for RNC is proposed to maximize multicast throughput. Its efficacy is evaluated through both numerical and event driven simulations. Next, we present the design of MFTP, a clean-slate transport protocol aimed for supporting efficient wireless and mobile content delivery. Current transport protocol of the Internet, TCP, is known to fall short if the end-to-end path involves wireless links where link quality varies drastically, or if the client is mobile. Building on a mobility-centric future Internet architecture, MobilityFirst (MF), a set of transport protocol components are designed to collectively provide robust and efficient data transfer to wireless, or mobile end hosts. These include en-route storage for disconnection, in-network transport service, and hop-by-hop delivery of large chunks of data. A research prototype is built and deployed on ORBIT testbed to evaluate the design. Results from several wireless network use case evaluations, such as large file transfer, web content retrieval, and disconnection services, have shown that the proposed mechanisms achieve significant performance improvement over TCP. Finally, a scalable, network-assisted congestion control algorithm is proposed for the MobilityFirst future Internet architecture. In MobilityFirst, various intelligent functionalities, such as reliability and storage, are placed inside the network to assist with data delivery. Traditional end-to-end congestion control such as that carried out by TCP becomes unsuitable as it is unable to take advantage of such in-network functionalities. We design a congestion control policy that uses explicit congestion notifications from network routers and rate control at traffic sources. The hop-by-hop reliability provided in MF simplifies end-to-end reliable delivery of wireless/mobile data, but often requires routers to keep per-flow queues to carry out congestion control which could become impractical in the presence of a large number of flows. Our approach builds on a per-interface queueing scheme, and we show through simulation that it is able to substantially improve delay, fairness, and scalability with only

Download or read book Improving Internet Multicast with Routing Labels written by and published by . This book was released on 1997 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IP-multicast architecture is extended with addressing information along multicast routing trees that permits more efficient and sophisticated multicast routing options and encourages communication and cooperation between IP and higher-layer protocols. The Addressable Internet Multicast (AIM) architecture is introduced that enables sources to restrict the delivery of packets to a subset of the receivers in a multicast group on a per-packet basis, permits receivers to listen to subsets of sources on a subscription basis, provides nearest-host routing, and allows higher-layer protocols to place packets into application-defined logical streams, sot that hosts may direct the multicast routing of packets based on application-defined contexts. In addition, the Reliable Multicast Architecture (RMA) is introduced to support end-to-end reliable multicasting using heterogeneous reliable multi-cast protocols and providing acknowledgment trees implicitly, thereby eliminating the ACK implosion problem and allowing NAK-avoidance algorithms to work within local groups.

This book was released on 2010-06-09 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: An oft-repeated adage among telecommunication providers goes, “There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can’t do all ve, at least do the rst three. ” Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

Available in PDF, EPUB and Kindle. Book excerpt: In a computer network, multicast provides an efficient many-to-many service by constructing a delivery tree across all the members of the multicast group. There are a number of existing protocols for performing multicast routing. This work improves the field of multicast routing by presenting a new protocol that can be used to construct a hierarchical multicast tree composed of heterogeneous multicast domains. It also shows how this protocol can also be made secure, so that only authorized multicast members may use the multicast tree to send and receive data. Finally, this work presents multicast as a method of providing anonymity for participants in Internet communication.

Download or read book Cyber Security written by Markus Mack and published by Scientific e-Resources. This book was released on 2018-10-21 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cybersecurity refers to the measures taken to keep electronic information private and safe from damage or theft. It is also used to make sure these devices and data are not misused. Cybersecurity applies to both software and hardware, as well as information on the Internet, and can be used to protect everything from personal information to complex government systems. Cyber security is a distributed problem partly because of the distributed nature of the underlying infrastructure and partly because industries, government and individuals all come at it with different perspectives. Under these circumstances regulation is best attempted from the bottom up, and legalisation, especially in the area of criminal law, should be sharply focused. There is the need for distributed approaches instead of the more traditional single, concentrated approach. Cybersecurity is the body of technologies, processes, and practices designed to protect networks, computers, and data from attack, damage, and unauthorized access. Cybersecurity training teaches professionals to spot vulnerabilities, fend off attacks, and immediately respond to emergencies. The spread of modern information technologies has brought about considerable changes in the global environment, ranging from the speed of economic transactions to the nature of social interactions to the management of military operations in both peacetime and war. The development of information technology makes it possible for adversaries to attack each other in new ways and with new forms of damage, and may create new targets for attack. This book fully introduces the theory and practice of cyber security. Comprehensive in scope, it covers applied and practical elements, theory, and the reasons for the design of applications and security techniques. It treats both the management and engineering issues of computer security.
