Alternate marking usage for loss location in per-packet load balancing networks

Many per-packet load balancing schemes have been proposed to mitigate network load imbalances. However, due to the randomness of packet paths, loss location is challenging in per-packet load balancing networks. An efficient solution is to leverage the alternate packet marking technique. This draft analyzes the usage and requirements of alternate packet marking for packet loss detection and location in per-packet load balancing networks.
