and, it includes the questions of what operators will be willing to
deploy. One of the questions on the table, for example, is whether
the network might be willing to characterize available capacity on
links in datagrams that traverse them, either in an IP option or some
interior header such as an IPv6 hop-by-hop option. The canonical
variants there are XCP and RCP.
As I understand it, the conference organizers want to do something
about TCP, but the examples of why it should be done that they are
bringing up related to video and other applications. So this is going
to have to extend to some variation on a session layer (SIP, for
example), and potentially protocols like dccp.
