A Internet cresceu na comunidade acadêmica, de modo que mecanimos de segurança não eram parte do protocolo original IP e do projeto de serviços. Durante a discussão de redefinição do atual Protocolo Internet (1Pv4), se tomou claro que o novo projeto (1Pv6) deveria incorporar algumas características básicas de segurança. A intenção era que estas características provessem autenticidade, privacidade e um nível mínimo de segurança contra muitos ataques baseados no IP. A provisão de características de segurança em 1Pv6 (IPSec) é um passo importante em direção a prover segurança nativa na Internet. Entretanto, IPSec não é a solução para todos os problemas de segurança. O objetivo deste trabalho é analisar as implicações da adoção de 1Pv6 em Ambientes Cooperativos Seguros, particularmente do IPSec, que provê um framework nativo de segurança para a camada IP, assim como para as camadas acima. Será visto que a característica de criptografia fim-a-fim do IPSec impossibilita a utilização efetiva de vários mecanismos de segurança consolidados em Ambientes Cooperativos Seguros atuais (1Pv4). Considerando que uma rede IPv6 não será efetivamente útil se não permitir a ocorrência de comunicação com outras redes na Internet, tanto 1Pv4 quanto 1Pv6, este trabalho também objetiva estudar os cenários de integração entre redes 1Pv6 e 1Pv4 bem como os mecanismos de transição aplicáveis a cada cenário.

This specialized book is for the Ryu development framework, which is used to achieve Software Defined Networking (SDN). Why Ryu? We hope you can find the answer in this book. We recommend that you read Chapters 1 to 5, in that order. In Chapter 1, a simple switch hub is implemented, and in later chapters, traffic monitor and link aggregation functions are added. Through actual examples, we describe programming using Ryu. Chapters 6 to 8 provide details about the OpenFlow protocol and the packet libraries that are necessary for programming using Ryu. In Chapters 9 to 11, we talk about how to use the firewall and test tool included in the Ryu package as sample applications. Chapters 12 to 14 introduce Ryu's architecture and introduction cases. Finally, we would like to say thank you to those people, in particular users, who supported the Ryu project. We are waiting for your opinions via the mailing list. Let's develop Ryu together!

Data Center Virtualization Fundamentals For many IT organizations, today’s greatest challenge is to drive more value, efficiency, and utilization from data centers. Virtualization is the best way to meet this challenge. Data Center Virtualization Fundamentals brings together the comprehensive knowledge Cisco professionals need to apply virtualization throughout their data center environments. Leading data center expert Gustavo A. A. Santana thoroughly explores all components of an end-to-end data center virtualization solution, including networking, storage, servers, operating systems, application optimization, and security. Rather than focusing on a single product or technology, he explores product capabilities as interoperable design tools that can be combined and integrated with other solutions, including VMware vSphere. With the author’s guidance, you’ll learn how to define and implement highly-efficient architectures for new, expanded, or retrofit data center projects. By doing so, you can deliver agile application provisioning without purchasing unnecessary infrastructure, and establish a strong foundation for new cloud computing and IT-as-a-service initiatives. Throughout, Santana illuminates key theoretical concepts through realistic use cases, real-world designs, illustrative configuration examples, and verification outputs. Appendixes provide valuable reference information, including relevant Cisco data center products and CLI principles for IOS and NX-OS. With this approach, Data Center Virtualization Fundamentals will be an indispensable resource for anyone preparing for the CCNA Data Center, CCNP Data Center, or CCIE Data Center certification exams. Learn how virtualization can transform and improve traditional data center network topologies Understand the key characteristics and value of each data center virtualization technology Walk through key decisions, and transform choices into architecture Smoothly migrate existing data centers toward greater virtualization Burst silos that have traditionally made data centers inefficient Master foundational technologies such as VLANs, VRF, and virtual contexts Use virtual PortChannel and FabricPath to overcome the limits of STP Optimize cabling and network management with fabric extender (FEX) virtualized chassis Extend Layer 2 domains to distant data center sites using MPLS and Overlay Transport Virtualization (OTV) Use VSANs to overcome Fibre Channel fabric challenges Improve SAN data protection, environment isolation, and scalability Consolidate I/O through Data Center Bridging and FCoE Use virtualization to radically simplify server environments Create server profiles that streamline “bare metal” server provisioning “Transcend the rack” through virtualized networking based on Nexus 1000V and VM-FEX Leverage opportunities to deploy virtual network services more efficiently Evolve data center virtualization toward full-fledged private clouds

The book presents a comprehensive account of research and development activities in open, ditance and flexible learning from acknowledged experts from around the world. The use of open, distance and flexible learning materials is expanding dramatically, not just in schools, further and higher education but also in industry, commerce and the social services. Most higher education institutions now have an open learning unit or educational development centre, and major organisations such as british Steel, National Westminster Bank, Leeds Building Society, Rover Cars and the Inland Revenue have formed units to develop teaching and training materials. Internationally, growth is even more impressive, with new open universities planned for Singapore, Bangladesh, South Africa and india, whist those in Malaysia, Thailand and Australia continue to expand. But current and future practice must be based on research evidence rather than intuition. With contributions from all the leading names in this field, this book will be a key sourcbook for teachers, trainers and students.

A state-of-the-art guide to middleware technologies, and their pivotal role in communications networks. Middleware is about integration and interoperability of applications and services running on heterogeneous computing and communications devices. The services it provides - including identification, authentication, authorization, soft-switching, certification and security - are used in a vast range of global appliances and systems, from smart cards and wireless devices to mobile services and e-Commerce. Qusay H. Mahmoud has created an invaluable reference tool that explores the origins and current uses of middleware (highlighting the importance of such technologies as CORBA, J2EE and JMS) and has thus compiled the roadmap to future research in this area. Middleware for Communications: discusses the emerging fields of Peer-to-Peer (P2P) and grid middleware detailing middleware platforms such as JXTA and the Globus middleware toolkit. shows how Middleware will play a significant role in mobile computing. presents a Platform Supporting Mobile Applications (PLASMA) - a middleware platform that consists of components for location, event, and profile handling of Location-Based Services. introduces middleware security focusing on the appropriate aspects of CORBA, J2EE, and .NET and demonstrates how to realize complex security capabilities such as role-based access control (RBAC) and mandatory access control (MAC). discusses how Quality of Service (QoS) component middleware can be combined with Model Driven Architecture (MDA) technologies to rapidly develop, generate, assemble and deploy flexible communications applications. This incomparable overview of middleware for communications is suitable for graduate students and researchers in communications and computing departments. It is also an authoritative guide for engineers and developers working on distributed systems, mobile computing and networked appliances.

The Internet is connecting an increasing number of individuals, organizations, and devices into global networks of information flows. It is accelerating the dynamics of innovation in the digital economy, affecting the nature and intensity of competition, and enabling private companies, governments, and the non-profit sector to develop new business models. In this new ecosystem many of the theoretical assumptions and historical observations upon which economics rests are altered and need critical reassessment.
