You also permit easier movement of data between cloud locations and data centre by abstracting critical network controls. Software-defined networking (SDN) technology is an approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance and monitoring, making it more like cloud computing than traditional network management. Depuis 2010, le Cloud change de visage avec l'arrivée de mécanismes d'automatisation de gestion des serveurs et du stockage, ainsi que de l'autoconfiguration du réseau. La figure 1 présente l’architecture SDN et la place d’Openflow. Some of these recommendations are already included or investigated for ETSI NFV Release 2 specifications are in progress, and further work may be conducted for other topics. Each different type of enterprise architecture framework has its particular benefits and focus. SDN: (Decoupling hardware from Software) SDN architecture is divided into 3 layers. We aim at: i) investigating the characteristics (target environment and problems to solve) of integrated NFV/SDN Below is a brief description of the two types of Application Intents used by SDN-IP. I vetted this architectural view in 2012 and 2013 with many SDN and NFV experts at key service providers and manufacturers in the industry, so we believe it is sound. IP and MAC Quiz (BG prep Session) 14.10. ETSI NFV has recently published GS NFV-EVE 005 a Report on SDN Usage in NFV Architectural Framework that analyzes architecture, design patterns and use cases to drive some recommendations for the NFV community. Diagramme de l'architecture SDN. Its main distinguishing factor is the separation of the data plane from the control plane in routers and switches. While hybrid networks are more popular in the field, there is no clear consensus on how to best divide control functions locally inside a device and externally into a controller. Le protocole d’injection de règles SDN le plus connu est OpenFlow (version 1.0 à 1.5) Le contrôleur est, quant à lui, piloté par le besoin des applications. Software-defined WAN (SD-WAN) is a technology that applies the key SDN principles to WAN, and then extends them in innovative ways to address the practical realities of WANs, such as minimizing delays over long distances between nodes and providing predictable service quality over often unpredictable links. This model is for architecture offices that can deliver projects faster or for less money than the firms you are competing with for work. In other words, the control is decoupled from hardware and implemented in software. Economic law prevents architects from emulating their fellow artists in producing works for which the demand is nonexistent or only potential. Types of Architecture Firms Efficiency Based. Typically this means that you have developed a design and production process that is efficient and streamlined and are constantly looking for ways to improve upon it to make it more efficient.
