REsource LOcation And Discovery, a peer-to-peer (P2P) signaling protocol

SIP is a mature internet technology to establish sessions of any type across the internet. RELOAD stands for REsource LOcation And Discovery and is a peer-to-peer (P2P) signaling protocol standardised in IETF that provides its clients with an abstract storage and messaging service between a set of cooperating peers that form an overlay network. RELOAD defines a security model based on a certificate enrollment service that provides unique identities. NAT traversal is a fundamental service of the protocol.

The goal is to implement a P2P communications network based on IETF standards that allows people to communicate securely without the traditional interposed third parties like SIP service providers.

This is done both by establishing direct encrypted channels between the participants as well as using digital identities based on X509 certificates to identify the participants in a conversation, which will prevent third parties from inserting themselves into the conversation by attempting to impersonate one of the participants.

The outcome would be a working RELOAD implementation, with a functional backend for connecting and discovering peers based on their identity which is backed by an email address that will then also function as a working SIP address.
