Subject: [OASIS Issue Tracker] (MQTT-547) Consider whether current length encoding is acceptable
Ian Craggs created MQTT-547: ------------------------------- Summary: Consider whether current length encoding is acceptable Key: MQTT-547 URL: https://issues.oasis-open.org/browse/MQTT-547 Project: OASIS Message Queuing Telemetry Transport (MQTT) TC Issue Type: Improvement Components: MQTT-SN Affects Versions: MQTT-SN-1.2 Reporter: Ian Craggs From 'suggestions for 1.3' comments. The length encoding was extended for version 1.2 to support packets > 255 octets in length, in a backward compatible way. For packets of length > 255, the length field is 3 octets rather than optimally 2. Some options: 1) Always use 2 octets for the length 2) Length field is 1 or 2 octets long. 0 to 6 in the first octet means there is a second octet. The length can be up to 6*256 + 255 (=1791). 3) the MQTT algorithm, perhaps restricted to fewer octets. -- This message was sent by Atlassian Jira (v8.3.3#803004)
