Intent-based networking (IBN)


Intent-based networking (IBN) is a network administration model that uses artificial intelligence (AI), network orchestration and machine learning (ML) to automate administrative tasks across a network.

The goal of IBN is to reduce the complexity of creating, managing and enforcing network policies and decrease the manual labor associated with traditional configuration management. For example, an IBN command may look like this:



The IBN management application will then determine which devices and routes match the business intention and make the appropriate configuration changes automatically.



Intent-based networking and software-defined networking are similar in many aspects. Both approaches rely on a centralized controller to manage distributed devices on the network instead of individually managing each device from its own management console. Both approaches have the ability to understand network configuration and interaction across multiple devices.



Where the two approaches differ, however, is in how they are addressed at the administrator level. SDN continues to have a device-centric view of the network and commands are primarily about how devices should operate, but intent-based networking commands are issued from a business perspective. This second-level abstraction is the primary difference when it comes to intent-based networking vs. SDN.

Black swan

A  black swan event  is an incident that occurs randomly and unexpectedly and has wide-spread ramifications. The event is usually followed with reflection and a flawed rationalization that it was inevitable. The phrase illustrates the frailty of inductive reasoning and the danger of making sweeping generalizations from limited observations. The term came from the idea that if a man saw a thousand swans and they were all white, he might logically conclude that all swans are white. The flaw in his logic is that even when the premises are true, the conclusion can still be false. In other words, just because the man has never seen a black swan, it does not mean they do not exist. As Dutch explorers discovered in 1697, black swans are simply outliers -- rare birds, unknown to Europeans until Willem de Vlamingh and his crew visited Australia. Statistician Nassim Nicholas Taleb uses the phrase black swan as a metaphor for how humans deal with unpredictable events in his 2007...

A Graphics Processing Unit (GPU)

A graphics processing unit (GPU) is a computer chip that performs rapid mathematical calculations, primarily for the purpose of rendering images. A GPU may be found integrated with a central processing unit (CPU) on the same circuit, on a graphics card or in the motherboard of a personal computer or server. In the early days of computing, the CPU performed these calculations. As more graphics-intensive applications such as AutoCAD were developed; however, their demands put strain on the CPU and degraded performance. GPUs came about as a way to offload those tasks from CPUs, freeing up their processing power. NVIDIA, AMD, Intel and ARM are some of the major players in the GPU market. GPU vs. CPU A graphics processing unit is able to render images more quickly than a central processing unit because of its parallel processing architecture, which allows it to perform multiple calculations at the same time. A single CPU does not have this capability, although multi...

6G (sixth-generation wireless)

6G (sixth-generation wireless) is the successor to 5G cellular technology. 6G networks will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency. One of the goals of the 6G Internet will be to support one micro-second latency communications, representing 1,000 times faster -- or 1/1000th the latency -- than one millisecond throughput. The 6G technology market is expected to facilitate large improvements in the areas of imaging, presence technology and location awareness. Working in conjunction with AI, the computational infrastructure of 6G will be able to autonomously determine the best location for computing to occur; this includes decisions about data storage, processing and sharing.  Advantages of 6G over 5G 6G is expected to support 1 terabyte per second (Tbps) speeds. This level of capacity and latency will be unprecedented and wi...
