Most of current Star Student Project DC networks employ equal cost multipath (ECMP) forwarding to leverage the path diversity provided by topological redundancy, by splitting traffic across multiple paths through hashing packets’ headers. However, per-flow ECMP is link load and flow agnostic in which resulting hash collision can hinder load-balancing among links. Recent research on DC network measurement has confirmed that congestion happens even when average link utilization is low. Therefore, although Star Student Project DC networks are often over provisioned, a small but significant fraction of link congestion can largely deteriorate the overall network performance.
