                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.

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.

3.  Security Considerations

   TBD

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.
