Description: Group routing is a routing method that involves managing multiple routes as a single group for greater efficiency. This approach allows network systems to optimize data transmission by grouping similar routes, which reduces complexity and improves resource utilization. Instead of treating each route individually, group routing enables data packets to be sent through a predefined set of routes, thereby facilitating traffic management and minimizing congestion. This method is particularly useful in large and complex networks, where the number of routes can be overwhelming. By grouping routes, more effective routing policies can be applied, and network resilience can be improved, as traffic can be redirected to another route within the same group if one route fails. Additionally, group routing can contribute to better quality of service (QoS), ensuring that critical data is transmitted with priority. In summary, this approach not only simplifies routing management but also optimizes the overall performance of the network.
