AI Technical Summary
The existing Dragonfly topology suffers from inter-group link congestion and network performance degradation when facing different traffic patterns. While adaptive routing mechanisms can alleviate congestion, they increase link bandwidth consumption and latency. Static reconfiguration technologies such as Flexfly cannot adapt to real-time traffic changes.
An incremental dynamic topology reconfiguration method is adopted, which collects traffic and topology information through network monitors, generates reconfiguration instructions, dismantles and recreates links, and combines local flushing and rerouting techniques to dynamically adjust the network topology to adapt to traffic changes.
It effectively alleviates inter-group link congestion, improves link bandwidth utilization, reduces packet transmission latency and stream completion time, enhances system performance and flexibility, and adapts to concurrent operation of multiple applications.
