1 Scope
The present document focuses on the management and control aspects of the F5G End-to-End network architecture
ETSI GS F5G 004 [1]. The present document specifies the End-to-End management and control architecture and its
related interfaces, including:
• The technical requirements and functional blocks of the domain controllers and the E2E orchestrator in the
F5G networks (Customer Premises Network (CPN), Access Network and Aggregation Network);
• The technical requirements and interface parameters of the northbound interfaces of the domain controllers of
the Customer Premises Network (CPN), the Access Network, the Aggregation Network, the Core Network,
and the E2E orchestrator.
NOTE: The technical requirements and functional blocks of the Core Network Controller is out of scope of the
present document. However, it is part of the management architecture and interface.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI GS F5G 004 [1] and the following apply:
alarm propagation relationship: logical association of a set of correlated alarms
NOTE: The logical association of a set of correlated alarms includes but not limit to derivative association, causal
association and time association.
autonomous domains: basic logical business entities to expose network resources/functionalities as
services/capabilities in support E2E lifecycle of automated intelligent network/ICT services
NOTE: The definition of this term comes from TM Forum IG1218 [i.2].
autonomous network: system of networks and software platforms that are capable of sensing its environment and
adapting its behaviour accordingly with little or no human input
NOTE: The definition of this term comes from TM Forum IG1230 [i.1].
domain: logical collection of network nodes and interconnecting links, including their management and control system.
A domain may be further divided into multiple sub-domains
NOTE: In F5G, a domain is a network segment with its domain controller.
event source: the network components where the root alarm event is generated
NOTE: The network components could be a network element or a port.
incident: set of correlated events
intent: formal specification of the expectations, including requirements, goals, and constraints, given to a technical
system
NOTE: The definition of this term comes from TM Forum IG1230 [i.1].
network segment: logical collection of network nodes and interconnecting links, grouped based on network
technologies or for administration purposes
NOTE: In F5G networks, there are four types of network segments: the Customer Premises Network (CPN),
Access Network (AN), Aggregation Network (AggN) and the Core Network (CN).
root alarm event: primary event of the original alarm event(s) that is triggered by the root cause of an incident
root cause: original cause or the critical factor(s) which leads to an incident

4 Requirements for E2E management and control of
F5G networks
4.1 Motivation
Guaranteed Reliable Experience (GRE) is one of the key dimensions of a F5G network, which enables the business
demand of highly sensitive services, high reliability and high availability communication, and high operational
efficiency.
To meet the requirements of GRE, the Management, Control & Analytics (MCA) Plane is introduced in the F5G
architecture, which is responsible for the management, control and analytics of the E2E F5G networks covering the
CPN, AN, AggN and CN.
The present document defines the F5G E2E management and control architecture as a subset of the overall F5G MCA
Plane as defined in ETSI GS F5G 004 [1].
4.2 General requirements and management aspects
