Open issues: Rather than creating new header and payload sections for each layer, protocol or application, should there only be one header section and one payload section, with another IE describing what it is? PROPOSAL: There is no requirement for layer 4 IE's, so there's no need for application level IE's. PROPOSAL: we want as generic information elements as possible. eg, we don't want IPv4HeaderPacketSection and IPv6HeaderPacketSection because the protocol information is already in the header. Also we don't want IPv4PayloadPacketSection and IPv6PayloadPacketSection because the payload is independant of the protocol. |
