First: happy new year to all I did OPSDIR review for document draft-ietf-bfcpbis-bfcp-websocket-13 Summary: ready for publication I do not see any specific operations and/or management issues with this document. Notes/nits/questions: - In the IANA considerations you register bfcp (lower case), i.e.: Subprotocol Identifier: bfcp while in the examples (like on page 5), you specify: Sec-WebSocket-Protocol: BFCP (upper case) Is the keyword 'bfcp' case insensistive? If so, maybe this could be specified/described somewhere. If not, is then the example or the registration incorrect? - You use the acronyms WS and WSS several times. I think they stand for WebSocketand Secure WebSocket? But I did not see that those acronyms were ever expanded in the draft text. Might be good to so so at least once (on first occurrance) Thanks, Bert Wijnen
