ILA is contained completely within the network layer. It is not required to be end an end protocol, it can be used on over segments within the network. This also means that ILA requires no changes to applications, DNS or, transport layer. For instance the 8+8 proposal changed the way TCP is computed and defined a new TCP option. ILNP is has similar requirements to be end to end and requires changes to transport layer. ILA is a means to create transparent network overlays. Functionally, it is pretty much equivalent to IP/IP encapsulation and could legitimately be considered a form of compressed encapsulation. > For instance, the 8+8 proposal made by Masataka Ohta, documented here in 2004 (but proposed in the mid-90s): > https://tools.ietf.org/html/draft-ohta-multi6-8plus8-00 > > Also, the GSE proposal made by Mike O’Dell, documented here in 1997: > https://tools.ietf.org/html/draft-ietf-ipngwg-gseaddr-00 > > In particular, how does ILA address the problems raised with these proposals that caused us to set them aside at the time? > > Is there an I-D that describes what you are proposing that I should read? > https://datatracker.ietf.org/doc/draft-herbert-intarea-ila/ defines the core data plane protocol. There's several other drafts, links for most of them have been posted on ila list. Tom
