Challenge 3: Corruption Loss Idea of having a transport endpoint detect and accordingly react to corruption poses a number of interesting questions regarding cross-layer interactions IP is designed to operate over arbitrary link layers, it is therefore difficult to design a congestion control mechanism on top of it, which appropriately reacts to corruption especially as the specific data link layers that are in use along an end-to-end path are typically unknown to entities at the transport layer Open issue: the IETF has not yet specified how a congestion control mechanism should react to corruption |
