Use NFV and SDN to implement 5G network slicing and nfvsdn5 g Slicing Network Slicing Network slicing will play a key role in the implementation of 5g, which allows operators to run multiple virtual networks on a single physical infrastructure. With the 5g commercialization in 2020, many people are wondering to what extent network function Virtualization (NFV) and software defined network (SDN) can extend.

Environment: xcode5.1+ios7.1Requirement: A attempted scroll to join B view; "A Addsubview:b.view"Problem:1. b view is loaded into a view, but OpenFlow's picture is not loaded. After debugging is OpenFlow the agent is not loaded. --The Viewdidappear method of B view is run;Analysis Reason:Suppose that a view included in a viewcontroller is added directly to a view. Just like this:[View1 AddSubView:viewController.view], so that our viewcontroller will n

SDN promotes vro Technology Revolution Over the past 30 years, IP networks centered on routers and switches have always followed Moore's Law to build a modern information civilization with other IT devices. As the core device at the WAN and LAN egress, routers have always played a key role and have undergone continuous development and numerous upgrades. Today, the router interfaces have changed from a wide variety of narrow-band interfaces, such as X

Comparison between openflow and traditional vswitches in layer-2 Forwarding (1) L2 forwarding and Vlan traps Generally, after a string of bits in the physical layer are connected to the data link layer, frames are formed and verified. Only frames that pass the verification are forwarded. The concept of forwarding is MAC address-based forwarding for vswitches. The first layer-2 forwarding device is only based on MAC addresses and is used in LAN ), lat

Editor's note: WhenSDN gets attention and develops research, there are still deviations from its understanding, which comes down to seven of deviations. In the past few years, theSDN concept has gained great attention in the industry. Most enterprises are aware of the existence of the technology and are systematically implementing it or evaluating it in a planned manner. At the same time, however, there are still widespread misconceptions about the technology, which comes down to a total of seve

performance is poor, but it has been basically satisfied. The network is implemented on the basis of L3 routing : Calico, Romana as the representative. Among them, Calico is widely circulated the performance of the best Kubernetes network implementation, based on pure three-layer routing to achieve network communication, combined with iptables implementation of security control, can meet the performance requirements of most cloud. However, because it requires that BGP be turned on on the ho

Tame your WAN: Apply SDN to the WAN and wansdn The network should have responded to the needs of users and applications. However, for a long time, the network does not meet our needs well, and the network forces users and applications to adapt to network restrictions. In enterprises, the IT department has been striving to ensure that the network security capability is consistent with the development of devices and applications. In the WAN, bandwidth
