8.6.6 - Traffic Shaping

Flashcards covering key concepts and definitions related to traffic shaping and Quality of Service in networking.

Control plane

Makes decisions about how traffic should be prioritized and where it should be switched.

Data plane

Handles the actual switching of traffic.

Management plane

Monitors traffic conditions.

Quality of Service (QoS)

Allows fine-grained control over traffic parameters; distinct from Class of Service.

Class of Service (CoS)

Categorizes protocols into groups requiring different service levels and provides a tagging mechanism.

DiffServ

A CoS mechanism that categorizes traffic for different service levels.

802.1p

A CoS protocol that provides a tagging mechanism to identify a frame or packet's class.

Multiprotocol Label Switching (MPLS)

A protocol that can reserve bandwidth and predetermine statistics for QoS.

Traffic shaper

A device that delays packets based on their content to prioritize traffic.

Traffic policing

A simpler device that fails to deliver packets once a configured traffic threshold is reached (often referred to as tail drop).

Tail drop

The process of dropping packets when a configured traffic threshold is reached.

Buffer overflow

Occurs when a traffic shaping device cannot store more packets due to high traffic volumes.

Random Early Detection (RED)

An algorithm utilized to manage traffic overflow on a traffic shaper.
