Connection admission control definition
Connection admission control (also known as CAC) is a network system that decides if new devices (like smartphones, laptops, or printers) can join. Before approving new connections, CAC checks the network has enough space and resources. If it does, new connections are allowed. If it doesn’t, new connections may have to wait until some other devices leave the network so there’s more room for them. Connection admission control is pretty important — it helps networks run well and avoid congestion.
How does connection admission control work?
- 1.When a new device (e.g., printer) wants to connect to a network, it sends a request.
- 2.The CAC system checks the network to see if it has enough space and resources for the new connection.
- 3.Based on what it finds, the system decides whether to allow the new connection.
- 4.If approved, the device is allowed to connect.
- 5.The CAC monitors the network and may disconnect some devices to keep it running smoothly if it becomes too crowded.
Connection admission control benefits
- CAC ensures that the network uses its resources wisely, only allowing connections that won't cause congestion or slowdowns.
- It maintains a high-quality network service for existing users and stops new connections from overwhelming it.
- CAC makes the network more stable by avoiding crashes and traffic jams.
- It improves network security by blocking unauthorized or harmful connections.
- CAC ensures users have a smooth experience with fewer disruptions and slowdowns.
- Companies may use CAC to plan for network growth — it’s a great source of insights into resource use and demand).
