I'll just note here as a general comment that part of the success (and really, beauty) of the IP architecture is its inherent simplicity. If SDN becomes a dumping ground for *gratuitous* complexity (as we are currently seeing in many venues) then it will fail. --dmm On Fri, Jan 25, 2013 at 10:08 AM, <sitara...@nmsworks.co.in> wrote: > We had Vint Cerf himself visit and talk to us today evening. > Amongst others, he highlighted to us Openflow and SDN allowing routing > based on content in addition to headers. > My immediate reaction was question that this being an antithesis to > standardization.....then Vint mentioned an example about routing based on > charactersitics of the data and routers selectively choosing to listen > (per my understanding of what Vint said, not certain i got it entirely.) > Could we say that the conventional protocols are more leaning towards > syntactic standardization (Bits in header fields have tightly defined > ranges and constructs). > Has Semantic standardization, pattern matching been done before at > IETF/IRTF? > Any relationship to Ontologies? > ARe the implications to correctness, convergence, routing loops and such > of algorithms in this context been formally studied? > Would it make sense to start halfway and have two header components, one > decided by the protocol and the other header components contents decided > by the application itself (this will form a special part of the data). > yet this part of the data being in a well defined restricted area of the > data..is this beginning to look like optical network framing where frame > at one layer is data for the other?
