Cisco IWAN (Intelligent WAN)

Cisco Intelligent WAN (IWAN) is the solution for a software-defined distributed network.

2019: Opportunities and IWAN components

Possibilities of a software-defined distributed network (SD-WAN) of Cisco as of April, 2019:

• Fast deployment of infrastructure of branches
  • Automatic adjustment and centralized operation will allow to prepare branches for work in read minutes.

• Simplification of management of SD-WAN
  • Select physical or virtual model of deployment for simple initialization and support of WAN services.

• Cost reduction and risk minimization
  • An opportunity to select any type of connection to WAN network helps to reduce costs without prejudice to security.

• Convenience to users
  • Deployment of new applications can be carried out in read minutes, having achieved bigger performance with smaller costs of resources of bandwidth.

IWAN are the cornerstone four components:

• Transport and independent structure:
  • It is possible to select any suitable combination of suppliers and technologies of connection.

• Intellectual routing:
  • Network traffic automatically goes on the best way that provides the high performance of applications.

• Optimization of operation of applications:
  • Optimization and caching of WAN network increases high-speed performance of applications.

• The protected connections:
  • The protected overlay network VPN and safe methods of enciphering help to block the attacks.

Using IWAN technology dynamic routing of traffic of applications is performed by the help taking into account quality of communication channels (a delay and loss in channels). It allows to support the required performances of applications and confidentiality of transmitted data, to control use of bandwidth and a status of the WAN connections.
