Cisco Systems has been granted a patent for a method that allows a device to obtain routing policies from multiple routers in a network. The device then identifies overlapping path segments and predicts congestion caused by certain routing policies. Based on this prediction, the device adjusts the routing policies to avoid congestion.

Method for adjusting routing policies to avoid congestion
A recently granted patent (Publication Number: US11777854B2) describes a method and apparatus for managing routing policies in a network to avoid congestion. The method involves obtaining a set of routing policies from multiple routers in the network, which specify different paths and time periods for rerouting traffic. The device then identifies overlapping path segments within the specified paths and predicts that certain routing policies will cause congestion along these overlapping segments. Based on this prediction, the device adjusts the routing policies to prevent congestion.
The patent claims also mention that the routing policies can be configured to use algorithms such as shortest path first (SPF) or constrained shortest path first (CSPF) for routing traffic in the network. The adjustment of routing policies can involve modifying the time periods specified by certain policies to avoid conflicts with other policies. Additionally, the patent describes a scenario where a predictive application aware routing engine installs routing policies to specific routers based on predictions of service level agreement violations. In this case, the device adjusts the routing policies by modifying the installed policy and notifying the routing engine.
The apparatus described in the patent includes one or more network interfaces, a processor, and memory to store the necessary processes. The apparatus performs similar functions as the method, obtaining routing policies, identifying overlapping path segments, predicting congestion, and adjusting the routing policies accordingly. The apparatus can also rank the routing policies based on expected traffic and adjust specific policies based on their ranking.
Overall, this patent presents a method and apparatus for managing routing policies in a network to prevent congestion. By identifying overlapping path segments and predicting congestion, the system can adjust the routing policies to ensure smooth traffic flow. This technology could be valuable in optimizing network performance and avoiding disruptions caused by congestion.
