Adaptive Machine Messaging Protocol (AMMP)

simple, byte-efficient, lightweight messaging protocol used to facilitate M2M communications and to build Internet of Things (IoT) connectivity into the edge device.

• developed and promoted by Axeda

• Minimal bandwidth consumption, to save cost on cellular/satellite connections
• Very small footprint, to fit into even resource-constrained devices

• HTTP/HTTPS
• RESTFful
• JSON Format
• HTTPS
• standard HTTP authentication and SSL/TLS transmission security.

Data Model

• Data items – machine/sensor data elements representing status and current readings
• Location – representing current geo-location as latitude, longitude, altitude
• Alarms – indicating problem situations and corresponding detail
• Events – condition reports
• Uploaded content – binary or file-based content sourced at the edge
• Downloaded content – binary or file-based content deployed from the Axeda Machine Cloud Connected Content™ application
