L2LS - Non-Blocking Flashcards
What does it mean for a Leaf and Spine network to be “non-blocking,” and why is non-blocking architecture crucial for data center networks?
Answer: A non-blocking network architecture, such as Leaf and Spine, means that every device can communicate with any other device without experiencing congestion or bottlenecks. In a non-blocking design, there are enough available network paths to allow simultaneous communication between all connected devices. This is crucial for datacenter networks to prevent performance degradation during peak usage and ensure low latency.
Explanation: This question assesses the candidate’s understanding of the concept of non-blocking architecture and its importance in datacenter networks.
How does Leaf and Spine architecture achieve non-blocking characteristics, and what are the benefits of non-blocking design in terms of network performance?
Answer: Leaf and Spine architecture achieves non-blocking characteristics by providing multiple, equal-capacity paths between devices. This minimizes contention and allows for high-bandwidth communication without bottlenecks. The benefits include consistent high performance, low latency, and the ability to support applications with heavy East to West traffic patterns commonly found in datacenter environments.
Explanation: This question tests the candidate’s knowledge of the mechanisms that enable Leaf and Spine networks to achieve non-blocking design and the positive outcomes in terms of network performance.
