Network recovery is critical capability that service providers must provide. It can be accomplished in four ways. Span, or local, protection is the most common recovery method. Another common method is path restoration which is accomplished end-to-end. Some service providers apply both span protection and path restoration in different parts of their networks in a “hybrid” configuration. Another more recent alternative is a feature in Multiprotocol Label Switching (MPLS) called “Fast Reroute.” This praxis addresses several fundamental problems related to each of the above network recovery options in large service provider networks. First, the effects of the numbers of links, demand unit sizes, and link size modularity have on the four recovery methods, individually and collectively, are examined. Next, the selection of the minimum cost recovery method given the presence and levels of the other options is determined. Finally, the cost differences of the recovery methods given any combination of the other options and their levels are presented.
Over the last few years, the use of the internet services and applications such as phone calls, e-mails, video conferencing, catch up TV, audio and video streaming in general, which heavily rely on the network communications has increased. Reliable connections between the end users are vital for providing such internet services. In such networks, link or node failures can occur suddenly and without any notifications which will make more interruptions for the data transmission between source and destination. Hence, the network performance will be reduced significantly since more time is needed to reroute the traffic, which can create sever interruptions for delay sensitive services such as voice and video. A pre-computed backup path in advance can provide a valuable solution to reroute the data packets during the network recovery time. In this book, we study several factors to compute the backup path between source and destination such as (network design, Bandwidth, Shortest path). We show results of several efficient algorithms that have been implemented to compute the best backup route until the routing protocol re-updates the new routing table.
As the scale of integration improves and technolgy shrinks, the more number of transistors are being packed into a chip that increases the density of the chip. This leads to the steady growth in the operating frequency and possesing capacity per chip, resulting in increased power dissipation. In modern VLSI systems, the clock is the most important signal because it controls the rate of data processing and communication. It provides a structured framework for dealing with high-complexity digital systems. Various survey and current research indicates that clock network consumes a large part of the total chip power. It is even much more than that of the ordinary logic used in the design. This book indicates the four novel low power flip-flops collectively called novel energy recovery flip-flops to reduce the power dissipation in a clock network. The energy recovery clocked flip-flops enable energy recovery from the H-tree based clock network, resulting in significant energy saving. The energy recovery flip-flops operate with a single phase sinusoidal clock generated by an efficient power clock generator.

Keep your network safe from security disasters with a dependable recovery strategy Companies are finally learning that a network disaster recovery plan is mandatory in these times, and they must be prepared to make difficult choices about network security. In the information-packed pages of this book, Annlee Hines shares her unique and diverse work experience. She explains that the first thing you need, whatever your business may be, is reliable information and an idea of what you need to protect, as well as what you are protecting it from. She then dives into a discussion of how much you can expect to spend depending on what kind of security your network requires. She also delves into addressing the variables that determine why your needs will not necessarily be the needs of your closest competitor. Most importantly, Hines writes this valuable material realizing that you already know how to do your job –it's just that you now have to reconsider just how vulnerable the information nervous system of your company really is. From major terrorist attacks to natural disasters to hackers, Annlee Hines explores how to defend your network and reviews such topics as: * Probes, viruses, worms, and Trojan horses * The most common vulnerabilities networks face * Understanding and justifying costs * Lessons to be learned from successful defense strategies * Preparing for the worst and the requirements of network survival * Remedies, cyber recovery, and restoration
