It is time to adopt IP parcels.
Fred, Thanks for the data and implementation, but I'm still not convinced that IP parcels should be adopted. Your data seems to show that when the networking stack processes large segments performance increases (fewer packets to process in the data path is a win). We've known this for a long time and that's why stacks commonly implement various segmentation techniques like GSO/TSO, GRO/LRO, UFO, USO, and more recently BigTCP. Also, within the data center, 9K MTUs are becoming common place which is even better than segmentation with 1500 byte MTU. The major difference between these techniques and IP parcels is that the segmentation techniques don't require any new protocol or changes to an existing protocol, whereas IP parcels requires protocol changes. So in order to justify IP parcels adoption, not just in IETF but also upstreaming into Linux, I think you'll want to show that it has significant benefits over the existing segmentation techniques to justify the complexities and cost of a new protocol.
