Length: 2 Days
IM NFV Training, IP Multimedia Subsystem (IMS) Network Functions Virtualization (NFV) Training Course
IMS NFV Training, Network Functions Virtualization (NFV) covers all aspects of IT virtualization technologies, virtual machines running different software and processes, applied to consolidate network equipment types with standard high volume servers, switches and storage components.
The objective of IMS NFV is to taking the physical networking devices commonly used today in IMS including switches, storage, routers, load balancers, firewalls, IDS, cloud computing infrastructure, etc. and virtualizes them in much the same manner as servers.
NFV decouples the network functions, such as network address translation (NAT), firewalling, intrusion detection, domain name service (DNS), and caching, to name a few, from proprietary hardware appliances so they can run in software
IMS NFV training shows attendees how to translate the classic network appliances to software modules running on high volume servers with high volume storage, interconnected by generic high volume switches and automatically orchestrated and remotely installed. IMS NVF training also covers the integration with Software Defined Networking (SDN) technologies, OpenStack and other frameworks.
The objective of IMS NFV NFV is to taking the physical networking devices commonly used today (switches, routers, load balancers, firewalls, antivirus, etc.) and virtualizes them in much the same manner as servers. IMS NFV will be used to scale out across IMS devices less expensively (scaling by simply adding compute power) and to automatically deploy devices as needed.
NFV’s goal can be summarized as automated provisioning of devices.
IMS Network Functions Virtualization (NFV) is a technical course covering technical aspects of IMS NFV and IMS NFV implementation .
