This BOF is to assemble a blue-ribbon panel to (1) identify and examine current operational problems with current Packet-over-SONET/SDH payload mappings (2) identify short-term fixes and work-arounds (3) establish a collaborative basis for a longer-term permanent solution which provides for new SONET/SDH mappings for general payloads carrying bit- and byte- framed HDLC with large packet sizes. With this mapping in place, all IETF protocols based on HDLC framing can simply use it and not have to bother with the complexities of SONET/SDH transport.
