欧盟第六框架计划（FP6）综合项目“End-to-endQualityofServiceSupportoverHeterogeneousNetworks”（EuQoS）给出了一系列在Inter上支持端到端QoS的新奇想法以及解决方案，本书基于EuQoS项目实施过程中得到的重要技术及学术成果，专门介绍了在异构的有线/无线网络中，实现端到端的QoS保障所需的机制、协议和系统架构，特别关注了测量技术、流量工程机制与协议、信令协议，以及支持公平性和QoS的扩展传输协议。本书在后一章特别展示了如何将这些机制和协议集合成一个综合的端到端QoS体系架构，以支持异构的有线/无线接入网的端到端QoS控制。在附录中，本书还给出了诸如仿真和模拟等QoS机制的评价方法和技术。本书内容新颖，深入浅出，可以作为计算机和通信网络专业的、研究生以及相关研究人员的参考书。
Award-winning author Rosemary Wells lays bare the senseless devastation of war in this stunning novel. As the Civil War breaks out, India, a young Southern girl, summons her sharp intelligence and the courage she didn’t know she had to survive the war that threatens to destroy her family, her Virginia home, and the only life she has ever known. A timeless heroine of inspiring drive and bravery, India holds on to her dream of forging a career in science, unheard-of for a woman, in the face of battle, starvation, and tragic loss. Rarely has the Southern perspective on the war been told so even-handedly for young adults as in this meticulously researched, poignant, and riveting novel.

After a successful debut last year, Once Upon a Fairy Tale is on its way to becoming a timeless, best-loved storybook. Stars from Steven Spielberg, Hugh Grant, and Martha Stewart to Whoopi Goldberg, Gwyneth Paltrow, Mike Myers, and Robin Williams bring four classic stories-The Frog Prince, Goldilocks and the Three Bears, Rumplestiltskin, and Little Red Riding Hood-to life. Your image of these well-loved characters will be forever changed by the illustrative contributions of Chris Van Allsburg, Anita Lobel, Barry Moser, Jerry Pinkney, and others. Included is a full-length compact disc with celebrities performing the stories-all to benefit the STARBRIGHT Foundation, established to improve the lives of seriously ill children.
