Given the stringent delay requirements and capacity constraints of the interactive ALM, it is (usually) still possible to create a system with a high path diversity at both the overlay and the IP layer. This results in a good protection against overlay node failures and IP losses. However, such a system should be carefully designed. It is not sufficient to maximize the overlay path diversity, as it does not automatically optimize the IP layer. Therefore, the authors should take into account not only the overlay-level information, but also the actual mapping of the overlay links on the IP layer.
