exist, and network devices are simply connected to each other to form a tree-like network structure. The configuration of network devices is simplified and unified, and the keyboard experts who operate on network devices at high speed are no longer needed. There is no need for complex connections between network devices. Everything is done by the various configurations issued by the Controller. In this case, the network relies on SDN and NFV. SDN is

5G network slicing advantages and challenges The fifth generation of mobile communication systems, referred to as 5 GB, refers to the fifth generation of mobile communication technology, which is also an extension after 4G. As of November 2017, 3GPP released the first 5g empty port (NR) standard. 5g pre-commercialization is expected in 2018 and 5g pre-commercialization in 2019. The International Telecommunication Union (ITU) will become the standard organization for the final release of standar

internal cloud environment, public cloud, or private cloud environment. There are various network devices on the market, from Server Load balancer and application delivery controllers to application acceleration, encryption, or cloud bridge devices. The migration from virtual network functions to Virtual Devices indicates that we will move more to network function Virtualization (NFV). NFV advocates that a

Center, for example, unified scheduling across the world, enable network functions to run in the most urgent places to ensure performance, or to run in the most cost-effective place. With such features and ideas, cloud computing is no longer a "Never quenching thirst" for telecom networks, but a "first month of near-water buildings ". Let's take a closer look at the mysteries of Wind River Open Virtualization alization Profile. Open Virtualization Profile is designed to minimize latency and pro

tools: SDN and NFV. SDN is an innovation oriented towards network architecture, and NFV is an innovation oriented towards device architecture, using these two tools makes it extremely simple to configure and deploy network devices, or directly distribute the forwarding table through the Controller, or directly issue the VXLAN configuration through the controller without manual intervention.

The fourth is to use a large number of IT technologies, including SDN and NFV, to make the pipeline smarter, separate control and bearer, and realize the "4.0 era" of the network ". Based on these objectives, China Mobile released its NovoNet network visi

report in 2014, Markets Markets Research predicts that cloud computing spending between 2013 and 2016 will increase by $677 billion. IT is understood that the total IT spending in 2013 was as high as $3.7 trillion. Carriers will rely heavily on cloud-level networks to meet market needs. To promote this transformation, a series of important and innovative technologies are currently under development. As a leader in a series of emerging technologies, Network Function Virtualization (

Integration of Neutron and SDN Controller In the entire SDN (Controller here) and OpenStack integrated big frameworks, individuals tend to understand through layers. That is, Neutron is integrated with SDN Controller. It is understood as "Application Layer (north direction)", SDN Controller is integrated with hardware and software network devices, and "management layer (south directio

First, the wide-area IPWAN network established by the router is a network with a wide range of applications. Generally, creating a new network is costly. Therefore, a large part of the demand is to expand the network capacity, A certain degree of compatibility is required technically. Therefore, the basic trajectory of router development and t

In addition, Brocade has made improvements to prevent DDoS attacks, enabling network devices to be linked to security devices. "With SDN, many functions can be done on the controller, and the flexibility and adaptability of the network are greatly enhanced." In addition, the Controller for SDN also has a number of supporting development software to facilitate users to develop their own two times. "Yuzhanyun said

the set of guest access and wireless access will become a unified packet network. when the integrated Guest access network and the wireless network are unified, operators will have more urgent need to introduce SDN . the reasons are as follows: SDN centralized control that enables end-to-end unified management and scheduling ; SDN a big advantage is business agility. And the set of customer access network is the starting point of business. Using SDN at the starting point of the bu
