Terminology for Computing in the Network
draft-irtf-coinrg-coin-terminology-00
Abstract
The term Computing in the Network (COIN) is used for a diverse set of
scenarios. Often associated with leveraging richer computing
capabilities within network elements, its clear scope is yet unknown.
This document tries to bring clarity to the current understanding of
COIN through defining a terminology to streamline corresponding
discussions.

1. Introduction
The ongoing development of ever richer computing capabilities within
network elements is often captured as Computing in the Network
(COIN). However, there are different interpretations of the term,
often revolving around the 'place' of execution, captured by the 'in-
network' aspect of COIN [TRANSPORT]. The different views range from
'only computations on networking hardware' on the one hand to 'COIN
is a subset of edge/cloud computing' on the other hand. These
differences in interpretation often lead to difficulties in
discussions.
The goal of this document is to contribute to the clarity in any
discussion on COIN through outlining what is a first understanding of
a terminology that ought to be used in such discussion. The first
definitions in this context were proposed by
[I-D.draft-kutscher-coinrg-dir-02] and later adapted by
[I-D.draft-irtf-coinrg-use-cases-02] before being moved to this
separate document for broader discussion.
With this in mind, this document captures the current state of
agreement on a common terminology. It is likely that the document
will (need to) see a future revision if this understanding is
improved through increased insights and changes in the views of the
community.
2. Terminology
Programmable Network Devices (PNDs): network devices, such as network
interface cards and switches, which are programmable, e.g., using P4
or other languages.

Internet-Draft COIN Terminology March 2023
(COIN) Execution Environment: a class of target environments for
function execution, for example, a JVM-based execution environment
that can run functions represented in JVM byte code
COIN System: the PNDs (and end systems) and their execution
environments, together with the communication resources
interconnecting them, operated by a single provider or through
interactions between multiple providers that jointly offer COIN
capabilities
COIN Capability: a feature enabled through the joint processing of
computation and communication resources in the network
(COIN) Program: a monolithic functionality that is provided according
to the specification for said program and which may be requested by a
user. A composite service can be built by orchestrating a
combination of monolithic COIN programs.
(COIN) Program Instance: one running instance of a program
COIN Experience: a new user experience brought about through the
utilization of COIN capabilities
3. Security Considerations
TBD
4. IANA Considerations

5. Conclusion
This document defines a core terminology for COIN at this point in
the work of COIN RG and is thus positioned as a living document which
may see revision in due course.
