Introduction [RELOAD] is a peer to peer protocol developed by the P2PSIP Working Group. Each RELOAD instance has a unique name, which is used by the process in section 10.2 of this specification to find the configuration servers, enrollment servers and bootstrap servers needed to join the overlay. The process assumes that the RELOAD instance name is a FQDN, and uses the process in [RFC2782] (SRV RR) to find the IP address of the HTTPS server that serves the configuration document for this overlay. This process is adequate when the management of the overlay does not need to be distinguished from the owner of the FQDN used as the instance name, which is the case most of the time. But there is a special class of overlays that, by definition, requires to be unique on the Internet and for which having the possibility of create instances would defeat their very purpose. This specification calls the kind of overlays that are not domain specific, but application specific "infrastructure overlays". 1.1. VIPR Infrastructure Overlay [VIPR] is a technology that is being standardized in the VIPR Working Group and that aims to build bridges between SIP islands by automatically provision SIP routes after the "ownership" of a PSTN phone number has been verified by an actual PSTN phone call. This technology uses an RELOAD overlay as a distributed database where mappings between phone numbers and servers responsible for the validation process are stored. The promise of VIPR to bridge these SIP islands cannot be fulfilled if there is more than one distributed database storing these mappings. 1.2. Bitcoin-like Infrastructure Overlay The existing Bitcoin [1] protocol is using an IRC channel to find the initial peer servers, but one can imagine a Bitcoin-like Internet currency that is built on top of RELOAD. If such Internet currency is ever implemented, it would also require a unique RELOAD instance. 1.3. BOINC-like Infrastructure Overlay BOINC [2] is a software which is used for donating computer resources for projects as diverse as SETI@Home, Malariacontrol.net and LHC@ Home. This kind of research benefiting humanity as a whole could probably be better served if implemented on a unique overlay.

Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 3. Requirements The following requirements can be identified as a starting point for the discussion about infrastructure overlays: REQ-1: The mechanism used to find the configuration servers of the infrastructure overlay MUST require as little administrative overhead as possible. REQ-2: The mechanism MUST NOT require that one entity must shoulder the burden for administratively supporting th eoverlay. REQ-3: The mechanism MUST ensure that no one can capture the overlay for its own gain. 4. Security Considerations TBD 5. IANA Considerations This document requires no IANA actions. 6. Acknowledgements Jon Peterson and Gonzalo Camarillo suggested to write this document, with Jon Peterson providing some of the ideas. This document was written with the xml2rfc tool described in [RFC2629]. 7. References 7.1.
