[gavinsunde]

As specified in the IETF draft: https://tools.ietf.org/html/draft-ietf-core-block-17, sending a single large file split into multiple blocks that fit into UDP packets.

Hi,

I have a question on SZX in the Block2 Option.

Does the payload bytes of the response packet MUST be exactly same as the SZX chosen in Block2 Option
or
Can it differ with that of SZX?

For example, I send a Block which is NOT the last block and I choose SZX = 2 (i.e., Block size is 64 bytes). But the actual payload in the response is 75 bytes or 57 bytes not 64 bytes. Is this valid?

Thanks!
