Hence IPvx should be taken as a service rather than taking IPvx and GUE as a service, IMO. GUE is supposed to be both signalling and content (data), where the data are IP packets. Take away the IP part and GUE isn't an E anymore. >> Services are expected to have version fields and subtype demultiplexing >> indicators, to so that all message variants of current and future versions can use >> a single port number. > Sure, the version field within the IPvx packet could be used for demultiplexing purpose. That demultiplexes within IPvx. There still needs to be a way to demultiplex non-IPvx packets (control) from IPvx. Joe
