Today, I will talk to you about the key demands of NFV and NFV, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

What are the key demands of NFV?

Based on standard high-capacity Server, storage and high-capacity Ethernet, applications provided by different Vendor are automatically deployed remotely on a unified infrastructure in the form of software.

1) decoupling software and hardware, and network applications are based on general hardware infrastructure.

2) Open, modular hardware and software, independent of each other, easy to integrate

3) Automation, completely automatic remote installation of software operations to general hardware and automatic management

Background:

1. NFV (Network Functions Virtualization) is initiated by operators to promote the IT and telecom industries, based on modern virtualization technology, to provide a new network product environment, reduce costs, improve efficiency and increase agile energy.

2. 13 Top operators (AT&T, Verizon, VDF, DT, T-Mobile, BT, Telefonica, etc.) released the NFV (Network Functions Virtualization) white paper at the SDN and Open Flow World Congress in October 2012.

3. NFV ISG (Industry Specification working Group) under ETSI in January 2013 is developing relevant standards, which mainly define the requirements and architecture of network function virtualization.

4. The biggest attraction of NFV is for operators to reduce costs, improve management, maintenance, network and business deployment efficiency, energy saving, and future open and innovative potential.

Goal:

With the development and deployment of cloud computing, the business can be migrated from Box solution to public cloud platform.

Source of NFV:

In 2012, a number of operators issued a technical white paper on NFV through ETSI (European Telecommunication Standards Institute). In the traditional network, all kinds of network functions are mostly realized by special hardware and special software. the software and hardware are highly dependent and can not be separated. The goal of NFV is to use the hardware and software commonly used in the industry to achieve a variety of network functions, including a variety of servers based on X86 architecture and a variety of general Ethernet switches and other cheap devices. NFV means that various network functions will be delivered to operators in software form, while network operators only need to install, run and maintain the software in a cloud computing data center environment.

NFVI is the legendary layer I, which fully virtualizes the hardware-related CPU/ memory / hard disk / network resources (in fact, it is in the virtualization software, re-numbering and dividing blocks with certain rules, and then providing the interface for application and scheduling through the virtualization software). The most famous of this virtualization software is VMWare.

On top of NFVI, network elements (VNF) decoupled from hardware are deployed, pure software, because they provide actual business, so they are called S layer. The resources below them are all "virtual resources" closed and hidden by virtualization software, and on the far right is the famous MANO, which is literally translated as "choreographer", which is the focus of the network management team, which is the management system of the cloud network.

After reading the above, do you have any further understanding of what are the key demands of NFV and NFV? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
