Internet Engineering Task Force M. Sustrik, Ed.
Internet-Draft
Intended status: Informational June 5, 2014
Expires: December 7, 2014
List of SP protocol IDs
sp-protocol-ids-01
Abstract
This document is intended to be a central repository of SP protocol
IDs. The intention is to pass the task to IANA later on.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."
This Internet-Draft will expire on December 7, 2014.

Internet-Draft List of SP protocol IDs June 2014
1. Introduction
Different mappings for scalability protocols (see, for example
SPoverTCP [SPoverTCP]) define a protocol header which in turn
contains SP endpoint type ID. The ID consists of protocol ID and end
the endpoint role:
+-----------------------+------------------------+
| Protocol ID (12 bits) | Endpoint role (4 bits) |
+-----------------------+------------------------+
Protocol IDs denote the SP protocol used (such as request/reply or
publish/subscribe), while endpoint role determines the role of the
endpoint within the topology (requester vs. replier, publisher vs.
subscriber et c.) Both numbers are in network byte order.
Protocol IDs are global, while endpoint roles are specific to any
given protocol. As such, protocol IDs are defined in this document,
while endpoint roles are defined in specific SP protocol RFCs.
Note that there's no versioning of SP protocols. New versions of old
protocols should register with new protocol ID.
2. Protocol IDs
1 - pair (v1)
2 - publish/subscribe (v1)
3 - request/reply (v1)
4 - unassigned
5 - pipeline (v1)
6 - survey (v1)
7 - bus (v1)
8 - slowsand (v1)
9-3839 - unassigned
3840-4095 local and experimental
3. IANA Considerations
This memo describes numbers that should be eventually managed by
IANA.
