Hi, We just submitted version -01 of “Large Record Sizes for TLS and DTLS”. Michael Tüxen is a new co-author, the extension has been renamed to the more mundane “large_record_size" and is now a flag extension. The flag extension is now used together with "record_size_limit" to allow negotiation of maximum record size, not just a fixed 2^16 – 1 bytes.
The use for record sizes larger than 2^14 has been discussed in TSVWG for use in DTLS over SCTP and DTLS in SCTP. Large record sizes would be beneficial in several of the discussed solutions to remove limitation or to increase performance. We would like to present draft-mattsson-tls-super-jumbo-record-limit-01 in Brisbane.

This document specifies a TLS flag extension to be used in combination with the record size limit extension allowing endpoints to use a record size limit larger than the protocol-defined maximum record size, but not more than about 2^16 bytes.
