This phase focuses on future-proofing the network and enhancing last-mile connectivity. It involves building a "ring topology" where districts and blocks are connected by redundant fiber paths, increasing network resilience and ensuring higher bandwidth capacity.
Detailed Explanation
Phase III of the BharatNet project aims to strengthen the telecommunications network by ensuring it is robust and can withstand failures. A 'ring topology' means that the network connections loop back on themselves, allowing for multiple pathways for data to travel. This setup not only increases the resilience of the network but also ensures that if one path fails, there is an alternative route for data to still reach its destination. It is like having multiple roads leading to the same destination β even if one road is closed, you can take another to reach where you need to go.
Examples & Analogies
Imagine a city with several highways connecting different neighborhoods. If one highway is blocked due to construction, cars can still reach their destination using alternative routes. This is how the ring topology in Phase III enhances connectivity; it provides different paths for data, ensuring that users remain connected even if one path is disrupted.
