Abstract

Проведенные исследование и анализ, а также состояние и тенденции развития мультисервисных сетей связи на базе архитектурных концепции NGN показали, что потенциал роста производительности телекоммуникационных терминальных, коммутационных и канальных оборудовании и пропускной способности системы на основе традиционных технологий практически исчерпан. Это связано со множеством факторов, в том числе с ростом затрат времени на маршрутизацию, с трудностями настройки сети и управления потоками в ней, особенно с ростом потребностей в виртуализации сетей, а также отображения нескольких логически изолированных сетей с независимыми политиками качества обслуживания на общий набор физических ресурсов.

Software-Defined Networking: A Comprehensive Survey
Article
Full-text available
  • Jun 2014
Software-Defined Networking (SDN) is an emerging paradigm that promises to change the state of affairs of current networks, by breaking vertical integration, separating the network's control logic from the underlying routers and switches, promoting (logical) centralization of network control, and introducing the ability to program the network. The separation of concerns introduced between the definition of network policies, their implementation in switching hardware, and the forwarding of traffic, is key to the desired flexibility: by breaking the network control problem into tractable pieces, SDN makes it easier to create and introduce new abstractions in networking, simplifying network management and facilitating network evolution. Today, SDN is both a hot research topic and a concept gaining wide acceptance in industry, which justifies the comprehensive survey presented in this paper. We start by introducing the motivation for SDN, explain its main concepts and how it differs from traditional networking. Next, we present the key building blocks of an SDN infrastructure using a bottom-up, layered approach. We provide an in-depth analysis of the hardware infrastructure, southbound and northbounds APIs, network virtualization layers, network operating systems, network programming languages, and management applications. We also look at cross-layer problems such as debugging and troubleshooting. In an effort to anticipate the future evolution of this new paradigm, we discuss the main ongoing research efforts and challenges of SDN. In particular, we address the design of switches and control platforms -- with a focus on aspects such as resiliency, scalability, performance, security and dependability -- as well as new opportunities for carrier transport networks and cloud providers. Last but not least, we analyze the position of SDN as a key enabler of a software-defined environment.

Guide to Security in SDN and NFV: Challenges, Opportunities, and Applications
Book
  • Jan 2017
This book highlights the importance of security in the design, development and deployment of systems based on Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), together referred to as SDNFV. Presenting a comprehensive guide to the application of security mechanisms in the context of SDNFV, the content spans fundamental theory, practical solutions, and potential applications in future networks. Topics and features: • Introduces the key security challenges of SDN, NFV and Cloud Computing, providing a detailed tutorial on NFV security • Discusses the issue of trust in SDN/NFV environments, covering roots of trust services, and proposing a technique to evaluate trust by exploiting remote attestation • Reviews a range of specific SDNFV security solutions, including a DDoS detection and remediation framework, and a security policy transition framework for SDN • Describes the implementation of a virtual home gateway, and a project that combines dynamic security monitoring with big-data analytics to detect network-wide threats • Examines the security implications of SDNFV in evolving and future networks, from network-based threats to Industry 4.0 machines, to the security requirements for 5G • Investigates security in the Observe, Orient, Decide and Act (OODA) paradigm, and proposes a monitoring solution for a Named Data Networking (NDN) architecture • Includes review questions in each chapter, to test the reader’s understanding of each of the key concepts described This informative and practical volume is an essential resource for researchers interested in the potential of SDNFV systems to address a broad range of network security challenges. The work will also be of great benefit to practitioners wishing to design secure next-generation communication networks, or to develop new security-related mechanisms for SDNFV systems.
