Table of Contents

1. Introduction

Mesh Presence Protocol (MPP) is a UDP publish/subscriber protocol. Devices subscribed to an event notification service associated with an account receive UDP notification of events posted to that channel. This service may be used to provide subscribing devices with immediate of an event without the need for polling.¶

Uses of the presence service include notifying a device that an inbound synchronous communication session has been requested, receipt of an asynchronous message, updates to a Mesh catalog, etc.¶

MPP provides NAT traversal capabilities similar to those provided by STUN . Combining these capabilities with a presence service avoids the need for a separate service. [rfc8489]¶

All MPP packets are encapsulated as RUD datagrams. Messages from the client to the service are limited to a single packet. Messages from the service to the client may contain between 1 and 16 packets.¶
