4 Requirements for E2E management and control of
F5G Advanced networks
4.1 Motivation
Guaranteed Reliable Experience (GRE) is one of the key dimensions of a F5G Advanced 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 MCA Plane is further enhanced in support of F5G Advanced, as defined in ETSI
GS F5G 024 [1].
The present document defines the F5G Advanced E2E management and control architecture as a subset of the overall
F5G MCA Plane as defined in ETSI GS F5G 024 [1].
4.2 General requirements and management aspects
In the following a general set of management aspects of the F5G Advanced E2E management and control system are
described:
• E2E service provisioning:
- The F5G Advanced network supports a rich set of applications and services traversing multiple network
segments. The F5G Advanced E2E management and control system shall support the instantiation,
configuration and maintenance of these F5G Advanced E2E services, including their creation,
modification and termination, and support the automation of the corresponding workflows.
ETSI
12 ETSI GS F5G 027 V1.1.1 (2025-12)
• Efficient network operation:
- The F5G Advanced network improves the efficiency of the network operation by an intelligent E2E
management and control system. The key requirements of this intelligent E2E management and control
system include:
 Network resource visibility: The F5G Advanced E2E management and control system shall support
the necessary functionality to provide the F5G Advanced network resource information to the
network administrators. This improves the efficiency for the network operators to operate and
manage their networks. Additionally, the system should support the visualization of the information
at a high-level of abstraction for administrators to see important system aspects.
 Intelligent fault management: The F5G Advanced E2E management and control system shall
support intelligent root cause analysis and alarm correlation analysis, which provides effective
guidance to the network operators for accurate troubleshooting. The management and control E2E
management and control system shall also support proactive fault management to identify and
eliminate potential risks in advance.
• Interoperability:
- In the F5G Advanced network, different network segments may be from different vendors. The F5G
Advanced E2E management and control system shall support the collaboration and orchestration of the
domain controllers for different network segments. This is achieved through open interfaces between the
E2E orchestrator and each domain controller. The F5G Advanced E2E management and control system
shall dynamically and automatically adapt to application and service requirements to enable Network as
a Service (NaaS). NaaS is a cloud-based networking model in which customers rent network and
cloud services from network providers. NaaS allows users to access networking functionalities (such as
routing, security, and bandwidth management) without maintaining their own physical networking
infrastructure. The key features of NaaS include:
 On-Demand Provisioning - Users request network resources dynamically.
 Scalability - Resources can be scaled up or down based on demand.
 Pay-As-You-Go - Users pay only for the network services they consume.
 Software-Defined Networking (SDN) Integration -NaaS offerings may use SDN to enable flexible
and programmable network control.
 Security & Compliance - Providers offer built-in security features, such as firewalls and encryption.
• Energy-efficiency management:
- The F5G Advanced E2E management and control system shall incorporate comprehensive energy
management capabilities across the entire network infrastructure. This includes the ability to monitor
real-time power consumption of network elements, analyse historical energy usage trends, and optimize
energy efficiency through intelligent control mechanisms. The system shall support energy-aware
orchestration policies that dynamically adjust resource allocation, power states, and service placement
based on traffic load and application requirements. AI-driven algorithms should be utilized to predict
low-utilization periods and enable proactive energy-saving actions, such as powering down idle
components or consolidating workloads. Additionally, the system shall provide visual dashboards and
reporting tools to ensure transparency in energy consumption and to support sustainability goals and
compliance with green networking standards.

5 Architecture of E2E management and control of F5G
Advanced network
5.1 Design principles
TM Forum IG1251 [i.3] defines the methodology, general principles, and the high-level business and technical
architecture of Autonomous Networks. The present document specifies he E2E management and control architecture as
an "Autonomous F5G Advanced Network", which enables the self-configuration, self-healing, self-optimizing and self-
evolving of F5G Advanced resources and services with less human intervention.
The design principles for this management and control architecture include:
• Autonomous domain:
- Each of the F5G Advanced domains, the CPN, the AN and the AggN (together with the management and
control system of that domain) are considered an autonomous domain. This enables the support of F5G
Advanced E2E services for autonomous end-to-end slice creation and adaptation.
- The F5G Advanced E2E management and control system shall dynamically and automatically adapt to
application and service requirements to enable Network as a Service (NaaS) since most of the services
and applications run in the cloud. The traffic flow from the user device to cloud service/application needs
to be established, monitored and adapted in all F5G-A autonomous domains.
• Intent-driven:
- Intent defines what is expected to be achieved but leaves the details of how the network is deployed and
operated to the autonomous domain. In the F5G Advanced E2E management and control system, the
interfaces exposing to the E2E Orchestrator the resources/functionalities of each autonomous domain
shall be intent-based. In this way, each F5G Advanced autonomous domain could be treated as a whole,
and the E2E management and control system does not need to be aware of the detailed information of
each domain.
- The F5G Advanced E2E management and control system focuses on the interaction and orchestration of
different autonomous domains through their intent-driven interfaces.
• NaaS:
- The F5G Advanced E2E management and control system shall also support a Northbound Interface to
configure the connections with a certain Quality on Demand (QoD) to enable the deployment of NaaS.
EXAMPLE: Some examples of NaaS offerings are:
 Virtual Private Network (VPN) - Secure remote access to enterprise networks.
 Software-Defined Wide Area Network (SD-WAN) - Enhances WAN connectivity and
optimizes traffic.
 Cloud-Managed Network Service - Includes managed firewalls, DDoS protection, and traffic
routing.
 Network Slicing - Used in 5G to create virtualized network segments with specific QoS.
• Closed-loop control:
- Based on the autonomous domain and intent-driven interfaces, it is possible to design the resource and
service control closed-loops in the F5G Advanced E2E management and control system. The service
control closed-loop enables the full lifecycle service operation, while the resource control closed-loop
enables the full lifecycle cross-domain and cross-layer resource orchestration.

• Simplicity:
- The concept of "simplicity" is a fundamental principle of network design. For management and control
aspects, it means fewer layers, interfaces, and protocols. Intelligent and automatic mechanisms enable
simplicity. In the F5G Advanced network, the E2E management and control system shall be hierarchical
and shall include intelligent components to simplify the architecture.
• Energy-efficiency management
- F5G Advanced is targeting green agile optical network. To cope with the green dimension, F5G
Advanced E2E management and control system shall provide a distributed mechanism to the
autonomous domain and the E2E orchestrator for collection, processing, and analysis of energy
monitoring data across various network segment domains (including CPN, AN, AggN and CN) and
technologies (including PON, IP/Eth, (fg)OTN and WDM).
5.2 Hierarchy architecture overview
5.2.1 F5G Advanced E2E management and control architecture
ETSI GS ZSM 002 [3] defines the End-to-End network and service management framework for multi-domain, multi-
technology and multi-layer networks with hierarchical service management domains. The management and control of
F5G Advanced networks is an instance of the ZSM architecture applied to optical communication networks.

Figure 1: F5G Advanced E2E management and control architecture
Figure 1 shows the F5G Advanced E2E management and control system architecture, which adds hierarchical
controllers and an orchestrator to the F5G Advanced network topology defined in ETSI GS F5G 024 [1].
NOTE 1: All the controllers and the orchestrator in this architecture are logical functional blocks, which are not
necessarily physical controllers in the network.
A domain controller is introduced for each F5G Advanced network segment:
• Customer Premises Network Controller (CPN Controller): Used to manage and control the CPN, including
FTTR (P-ONU, passive splitter(s) and E-ONUs), residential gateways (RGs), and CPEs. The CPN Controller
function includes management and control of the Underlay Plane (CPN network) and the SAP, SPP and SMP
in the Service Plane of the CPN Network. The CPN Controller could be deployed within the CPN or in a
remote location. In the remote deployment case, the management and control of the CPN is the responsibility
of the network operator.

NOTE 2: The CPN Controller may directly interact with the E2E Orchestrator through the I_cp interface.
Alternatively, the CPN Controller may only interact with the A
