I haven't seen this in the OAM work so far. PWE's VCCV has 3 or 4 different channels (code named CC types) and 3 or 4 different OAM mechanisms (code named CV types). And each of these has several variants and most have several possible encapsulations. Similarly in the MPLS-TP work we have a large number of options. For example, draft-ietf-mpls-tp-on-demand-cv has 3 different encapsulations (LSP-ping UDP/IP packet in MPLS, LSP-ping packet in UDP/IP in GACh, and "raw" LSP-ping packet in GACh with a new channel type). Why is it that no-one seems to object to a plethora of possible options for anything except the inner-most payload format?
