Queueing Delay

Queueing delay is the time a data packet spends waiting in a buffer before it can be transmitted across a network. This delay occurs when the rate of incoming data exceeds the capacity of the outgoing link, causing packets to queue up.

In busy market environments, sudden spikes in trading activity can lead to significant queueing delays, potentially causing stale data to be processed. Network devices like switches and routers must manage these queues effectively to prevent packet drops and maintain low latency.

Traders often prioritize their data streams using Quality of Service settings to minimize the impact of queueing on their most critical trade execution commands. Effective queue management is vital for maintaining performance during periods of high market volatility.
