assumed that the physical topology of the network can be separated, network resources can be virtualized, the complexity of the physical structure can be hidden, and the management and control of the logical layer can be unified to meet the changing network needs. SDN and openflow are the same solutions.Openflow and S

Network virtualization-FlowVisor: Network Virtual Layer (medium) 1. Concepts understanding and review As mentioned in the previous blog, slice is defined as an instance of a virtual network, and a sliced stream can be considered as a sub-space of the whole geometric space consisting of headers of all possible data packets. For example, the stream table items in

Quality of Service (QoS): QoS (Quality of services, quality of service) refers to a network that can utilize a variety of basic technologies to provide better service capabilities for specified network traffic and is a security mechanism for the network. is a technique used to solve problems such as network latenc

Nick McKeown, a professor of engineering at Stanford University, expects a new network processor to replace the ASIC currently used in routers and switches in the next decade; he said he has gone deep into the future of the Communication Processor: "and if you try to look at it with your eyes, it's like a network-based RISC processor." McKeown assists in promoting a software-defined

view and maps it to the physical view. Alan S. Cohen: When people talk about other methods, such as OpenFlow, they still mean hardware. Network virtualization is different from OpenFlow. What is Nicira's Distributed Virtual Network Infrastructure DVNI? What are the similarities and differences between it and other

The goal of SDN is to achieve an idealized enterprise network, separating network control from physical network topology, this creates an environment for sending traffic from the central management controller to all vswitches and routers. In a software-defined network environment, this software-based controller must ha

Author: Fan Jun Frank Fan) Sina Weibo: @ frankfan7 Network virtualization will be the last mile in the journey to realize the vision of a software-defined data center. IDC estimates that the network virtualization market will grow from 2013 million dollars in 360 to 2016 billion in 3.7. Many giants have made great strides, and many new startups have targeted this direction. Let's talk about what this means
