Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
Network admission control systems allow noncompliant devices to be denied access, placed in a quarantined area, or given restricted access to computing resources, thus keeping insecure nodes from infecting the network. The key component of the Cisco Network Admission Control program is the Cisco Trust Agent, which resides on an endpoint system ...
Admission control is a validation process in communication systems where a check is performed before a ... (such as a wavelength across an optical network) may be ...
Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of congestion is that an incremental increase in offered load leads ...

Call admission control (CAC) is a form of admission control that prevents or mitigates oversubscription of VoIP networks. CAC is used in the call set-up phase and applies to real-time media traffic as opposed to data traffic. CAC mechanisms complement and are distinct from the capabilities of quality of service tools to protect voice traffic ...
