Diffusing Update Algorithm

(also DUAL)

Diffusing update algorithm definition

The diffusing update algorithm is an algorithm used in some computer networks. It helps find the best paths for data to travel. DUAL is part of a Cisco-created system called EIGRP.

Here's how the diffusing update algorithm works:

Best path selection. DUAL helps routers in a network find the most efficient ways to send data.

Backup paths. Each router keeps a list of backup roads in case the primary path is unavailable.

Quick adjustments. DUAL quickly switches to a backup path if a route is blocked or changed.

Communication with neighbors. If a router doesn't have a good backup, it asks nearby routers for better ways.

Avoiding loops. DUAL ensures the chosen paths don't lead to loops so that data flows smoothly.

Use cases of diffusing update algorithm:

Business networks: DUAL is used in large company networks for efficient data flow.

Data centers: Helps manage the flow of large amounts of data in data storage facilities.

Internet of Things (IoT): Supports networks connecting many smart devices like home appliances.

Disaster recovery: Assists in keeping networks running smoothly during emergencies.

Service providers: Used in networks that deliver internet and other digital services.
