Cisco Intent-based networking represents the next evolution of network software management. Cisco intent-based networking or IBN uses machine learning and advanced orchestration to reduce the complexity of managing and maintaining network policies. Over the time, managing networks has always been a complex process.
Teams of network administrators have been responsible for managing network equipment provisioning user access configuring policies and ensuring the system is doing what it’s supposed to. Till now, many admins use command-line interfaces to control their networks unfortunately. However, this way of managing the network does not scale very well.
The idea of IBN is that the network administrator simply tells the network what their intent is and the network automatically implements it. The IBN configures the network hardware if the network changes. For example, if a new firewall is added or a new link is created, the IBN will change with it to maintain the intent.
Think of a hospital with a network carrying sensitive patient information using an intent based networking system, network administrators could dictate their intent that only doctors and nurses are able to interact with sensitive patient data and no other users have access the IBN automatically recognizes the identity of the doctor and enforces the access policy.
The security implications of IBN are promising. the IBN ingests the intent of the network administrator and can automatically maintain security policies. This frees up the network security administrators to focus on instant response rather than implementing policies.
Cisco intent-based networking is still in the very early days of development there are a plethora of startups and big name vendors that are developing IBN technology. some believe it could be the next revolutionary step in network management and that means it could be coming to a network near you someday soon.
Cisco offers multiple software for different intents within the network including Cisco vManage for Software-Defined WAN networked, Cisco Application Centric Infrastructure for data centers and Cisco DNA Center for LAN and Campus networks.
