Review Questions

• How do traffic rerouting algorithms contribute to maintaining network performance during periods of congestion?
  • Traffic rerouting algorithms play a crucial role in maintaining network performance during congestion by continuously analyzing the current state of the network. When congestion is detected on a particular route, these algorithms dynamically redirect data packets through alternative pathways. This not only helps avoid bottlenecks but also ensures that data continues to flow efficiently, enhancing the overall responsiveness of the network.
• Evaluate the relationship between traffic rerouting algorithms and load balancing techniques within a network's operational framework.
  • Traffic rerouting algorithms and load balancing techniques are closely related as they both aim to optimize data flow within a network. While traffic rerouting focuses on finding alternative paths during congestion or failure, load balancing ensures that no single server or pathway becomes overwhelmed with requests. Together, they create a robust operational framework that enhances network resilience, allowing for efficient resource utilization and minimizing downtime.
• Propose an innovative method for improving the efficiency of traffic rerouting algorithms in modern networks, considering emerging technologies.
  • To enhance the efficiency of traffic rerouting algorithms in modern networks, an innovative method could involve integrating machine learning techniques that predict traffic patterns based on historical data. By analyzing past congestion events and user behavior, these algorithms could proactively identify optimal routes before congestion occurs. This predictive approach, combined with real-time data analysis, would enable more effective rerouting decisions, leading to improved performance and reduced latency in data transmission.
