L2LS - Congestion Avoidance Flashcards
What is congestion avoidance in the context of Leaf and Spine networks, and why is it essential for data center environments?
Answer: Congestion avoidance in Leaf and Spine networks involves mechanisms that prevent or mitigate network congestion. It is crucial for datacenter environments because it ensures that network traffic can flow smoothly even during peak usage. Congestion avoidance mechanisms help maintain low packet loss and consistent performance.
Explanation: This question evaluates the candidate’s understanding of the concept of congestion avoidance and its significance in datacenter networks.
Can you describe a specific congestion avoidance mechanism commonly used in Leaf and Spine networks, and how does it work to manage and alleviate network congestion?
Answer: An example of a congestion avoidance mechanism is Quality of Service (QoS). QoS assigns different levels of priority to network traffic based on predefined policies. This ensures that critical traffic, such as voice or video, is given higher priority, while less critical traffic is appropriately managed, preventing congestion and ensuring optimal network performance.
Explanation: This question assesses the candidate’s ability to provide a concrete example of a congestion avoidance mechanism and their understanding of how it functions to manage network congestion effectively.
