Terminology for Computing in the Network
draft-irtf-coinrg-coin-terminology-01
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 by providing an overview of the terminology and definitions 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-04] 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.

Internet-Draft COIN Terminology July 2023
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. These devices are designed to provide
flexibility and customization options beyond the traditional static
configuration models.
*(COIN) Execution Environment:* a specific class of target
environments where functions or code can be executed, 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:* a specific running instance of a COIN
program, created to fulfill user requests or as part of a composite
service. It encapsulates the code, data, and resources necessary for
executing the program and delivering the intended functionality.
*COIN Experience:* the holistic outcome of adopting and implementing
COIN, encompassing the advantages and benefits that arise from
distributed computing capabilities within the network infrastructure.
*COIN Function:* a specific computation or task that can be invoked
as part of a program. It contributes to the overall functionality of
the program by providing a modular and reusable unit of computation.

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.
