This book addresses three important issues in VoIP networks: Quality of Service, pricing and security. In addressing Quality of Service (QoS), it introduces the notion of delay not exceeding an upper limit, termed the bounded delay, to measure the Quality of Service in VoIP networks. Queuing models are introduced to measure performance in terms of bounded delays. Closed form solutions relating the impact of bounding delays on throughput of VoIP traffic are provided. Traffic that exceeds the delay threshold is treated as lost throughput. The results addressed can be used in scaling resources in a VoIP network for different thresholds of acceptable delays. Both single and multiple switching po...
A chronological discriminatory events in author’s life while growing up in a dictatorial country including his participation and experience for a successful revolution of Bangladesh is articulated. All parents have a dream to leave some legacy for their children. My parents had the dream to leave his ancestral properties for all his 9 children. Seperation of British India into Pakistan and India created a human tragedy of killing, family seperation and hatred between Hindu-Muslims. Our family fell in that trap and we, all siblings, had to migrtae from Bangladesh first to India and then to other parts of the world almost penniless for the safety and security leaving everything behind. As of writing this book, that human tragedy still continues. Unfortunately, migration of minorities is one way from Pakistan and Bangladesh to India not that much from India to either Pakistan or Bangladesh. I wrote this book for my accomplished two children as a gift to be aware of the family tragedy as well as tragedies of million Bangladeshis hoping they may be inspired to make a change in the world for the sake of humanity. Hopefully, they will preserve the ideals and principles I stood for.
This book constitutes the refereed proceedings of the Third International Conference on High Performance Computing and Communications, HPCC 2007. The 75 revised full papers address all current issues of parallel and distributed systems and high performance computing and communication, including networking protocols, embedded systems, wireless, mobile and pervasive computing, Web services and internet computing, and programming interfaces for parallel systems.
In the not too distant future, internet access will be dominated by wireless networks. With that, wireless edge using optical core next-generation networks will become as ubiquitous as traditional telephone networks. This means that telecom engineers, chip designers, and engineering students must prepare to meet the challenges and opportunities that the development and deployment of these technologies will bring. Bringing together cutting-edge coverage of wireless and optical networks in a single volume, Internet Networks Wired, Wireless, and Optical Technologies provides a concise yet complete introduction to these dynamic technologies. Filled with case studies, illustrations, and practical...
In the 90s, new languages and architectures were developed, new systems and networks were produced and new applications invented. The basic topics discussed are; High Speed Data Communications Protocols, Services and Networks for high speed data and for combined voice and data applications - i.e. ATM, SMDS, Frame Relay - Network Management, OSS Platforms, OSI and other information Technology Services, Network Control and Routing, Emergency Control and Telecommunication Politics. This publication offers the material basis for propagating the most advanced ideas, products, decisions and results of the 90s, and thereby it celebrates the advancements of Computer Communication on the route towards a new era.
This work discusses the issues among people creating computer communication technology, the people using computer communication, the people impacted by it, and the regulators responsible for balancing the interest of these multiple groups.
This textbook presents the fundamental concepts and application of optical mineralogy in a very simple, systematic, and comprehensive way. The book is organized into 2 parts: Part I deals with the theory and techniques, and Part II provides a description of the optical properties of common minerals. The book is written in a lucid manner so that students are able to understand the realization behind the concepts in optics and the methods employed to elicit information about the interior of mineral crystals. All the subject fundamentals and related derivations are discussed in an easy and comprehensive way to make the students strong in the basics of optical mineralogy. The key features lie in the illustrations, examples, and questions at the end of each chapter to provide students with practical usage insights into optical mineralogy. The book benefits students who are taking introductory courses in optics to characterize rock minerals.
Includes entries for maps and atlases.
