1. Introduction
This document aims to provide a reference framework for Operations,
Administration and Maintenance (OAM) for Computing in the Network
(COIN). The framework describes a tripartite consultation mechanism
which includes consumers/providers registration, resource discovery/
allocation, resource occupation, and resource release/refund.
2. Aspects Monitored by COIN OAM?
In this framework, the device and platform will be regarded as a
consumer or a provider of a computing power. One and the only
manager will be responsible for the management of computing power and
the contracts between consumers and providers.
2.1. Computing Power Consumer
Computing Power Consumer (or CPC, for short) is an application that
needs computing power from the network. As a consumer, the
application instance must register to CCM and be assigned a node id,
which is a unique identifier in a COIN system.

Internet-Draft Network Working Group July 2020
2.2. Computing Contract Management
Computing Contract Manager (or CCM, for short) is an application that
is responsible for register administration of all the CPCs, CPPs and
the Algorithm Repository. It can connect the consumers of computing
power and the providers of computing power. It also signs the
contracts for both sides.
2.3. Computing Power Provider
Computing Power Provider (or CPP, for short) is an application that
verifies the system having sufficient computing power available for
external applications. As a provider, the application instance must
register to CCM and be assigned a node id, which is a unique
identifier in a COIN system.
3. Consultation Mechanism of COIN
3.1. Register
CPC and CPP must register to CCM to confirm its role in the COIN
system. An application instance can be a CPC and a CPP concurrently.
In REGISTER Request message, the role field is a mandatory field.
The CCM must assign a unique node id for the application instance and
put it in the REGISTER Response message. The CCM has all the records
of the CPC and CPP.

(1)REGISTER Request message includes:
*Role type, identifying the role of the computing power contract. It
may be consumer or provider

(2)REGISTER Response message includes:
*Role type, identifying the role of the computing power contract. It
may be consumer or provider
*computing node id, unique node id assigned by CCM.
3.2. Discover/Allocate
When a CPC meets distributed computing task,it seeks for computing
power from CCM by DISCOVER Request message,along with the computing
power requirements and corresponding algorithm requirements. Now
that CCM has all the records of CPPs,it can choose one or more
appropriate CPPs and send ALLOCATE Request message to them. The
message at the same time contains the computing power requirements
and corresponding algorithm requirements.
After the CPP has prepared for the necessary computing power and
algorithm function, it sends ALLOCATE Response message to CCM with
its provider node id and a serial number.After the CCM send DISCOVER
Response message to CPC, the contract between a CPC and a CPP has
been signed through CCM.

3.3. Occupy
After the contract is signed by both sides, CPC starts using remote
computing power. Through OCCUPY messages.

3.4. Release/Refund
Once CPC finishes a complete calculation,CPC should release computing
power via CCM,and CCM should refund the computing power to CPP.
