The effects of badly behaved routers on Internet congestion

From an exhaustive series of trace packets to a diverse set of destinations, our research has discovered that specific routers are the cause of bottlenecks in the Internet. We found that packets took the same route each time towards their destination. Our research has also found that over periods as large as seven days these routers continue to cause bottlenecks with no re‐routing of packets to alleviate congestion. This research begs the question as to why these bottlenecks occur at the same places and for so long a period and also queries the extent of implementation of dynamic routing algorithms.
