I think he/she is not talking about the transport protocol (TCP/UDP), but the higher up layers (5 - 7) cramming functionality from the lower layers. Might be reading it the wrong way.
- detaro 12y agoThey only try to cram functionality from lower levels into higher ones because establishing new lower ones is nearly impossible. SCTP (or variants of it) would implement a lot that is now build on higher levels, but there is a reason it's only used in private networks.
- Chlorus 12y agoNo kidding, take a look at the presentation[0] for multipath TCP - and that was a relatively 'simple' transport layer modification. Look at slide #30 for a glimpse into the madness caused by crappy middleboxes. [0]http://multipath-tcp.org/data/MultipathTCP-netsys.pdf http://multipath-tcp.org/data/MultipathTCP-netsys.pdf
