• Purpose: High Performance Relay for Protocol Federation
• Endpoints: WebSockets, MQTT, MQTT-SN, TCP, UDP, CoAP via EMQ
• Codebase: 500 LOC
• Buildtools: REBAR, MAD
• Templates: DTL, NITRO
• Hosts: Cowboy, EMQ, Mochiweb
• Error Logging: LAGER
• Samples: N2O Review Application for MQTT (1)

N2O 4.5 MQTT is what you get when you reduce everything duplicating MQTT features. On the other hand, N2O 4.5 MQTT is completely N2O-compatible embeddable protocol relay.

• n2o.erl — N2O: Protocol Server 4.5 for MQTT
• n2o_async.erl — N2O Async: gen_server
• n2o_format — N2O Formatter: JSON, BERT
• n2o_ftp — N2O File: FTP
• n2o_nitro — N2O Nitro: PICKLE, FLUSH, DIRECT, IO, INIT
• n2o_proto — N2O Protocols: NITRO, FTP
• n2o_secret — N2O Security: HMAC AES/CBC-128
