Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and
Systems (SES).
Introduction
The focus of the present document is on the functional architecture of network management for BSM systems,
including the management of IP-based services.
Network Management of IP-based broadband satellite multimedia (BSM) systems may be chosen to be similar in many
ways to that of terrestrial networks. However there are important differences in emphasis, for example in that the
management traffic overhead across a satellite system should be minimised. Also the scalability of satellite networks
interconnecting potential many terminals must be considered. Furthermore, integrated management of satellite and
terrestrial IP networks has not been widely implemented and a standardised approach is considered desirable.
The BSM network management system (BNMS) should also be designed to cope with the latency and bandwidth
asymmetry that are characteristic of satellite links. However the timescale of management operations is usually of an
order that does not impose tight time constraints or high data rates.

1 Scope
The present document defines an open specification dealing with scenarios and functional network architectures for the
management plane (M-plane) of Broadband Satellite Multimedia (BSM) systems, including any potential interfaces
with external or higher level network management functions. The BSM management functions should include, for
example, performance management, security management and QoS management, including the associated management
functions of Service Level Agreements (SLAs) and Policies.
The BSM management functional architecture will take into account requirements for emerging IP-centric (Internet
Protocol) broadband multi-service satellite-based networks, integrated with fixed and wireless (broadband) access
networks on one side, and backbone networks on the other. This internetworking and service interoperability scenario is
generally within the scope of Next Generation Networks.
The boundaries of the BNMS will be defined as well as the interfaces, protocols and message types on the internal and
external interfaces. The specification will include, where appropriate, the BSM SI-SAP protocol stack interface
including its interactions with higher and lower layers.
The architecture specified will be concerned mainly with the lower layers of the management functional layers,
particularly the service management, network layer management and network element management, which will allow
maximum flexibility for compatibility and mediation with OSS equipment as well as for Operators in building
functionality as they see fit.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
agent: entity that acts in a managed role
architecture: abstract representation of a communications system
NOTE: Three complementary types of architecture are defined:
functional architecture: discrete functional elements of the system and the associated logical
interfaces
network architecture: discrete physical (network) elements of the system and the associated
physical interfaces
protocol architecture: protocol stacks involved in the operation of the system and the associated
peering relationships
control plane: layered structure that performs the call control and connection control functions; it deals with the
signalling necessary to set up, supervise and release calls and connections
Customer Premise Network (CPN): customer's private network
NOTE: In the simplest case, the CPN is just a single end-host or TE.
data link layer: second layer of the OSI model it provides connectivity between segments of the network (bridging); in
addition the data link may perform session control and some configuration
data model: description of a specific data structure, with the way the data elements (in the structure) are defined and
the relationship to each other
NOTE: It is normally used in software engineering to describe how data is represented and accessed (see also
RFC 3444 [i.15]).
eTOM: business process model or framework that has the objective of describing and classifying the business
processes required for a Service Provider; it analyses the processes to different levels of detail according to their
significance and priority for the business
NOTE: eTOM uses hierarchical decomposition to structure the business processes according to which all of the
processes of the enterprise are successively decomposed. Process elements are formalized by means of a
name, a description, inputs/outputs, etc.
flow: flow of packets is the traffic associated with a given connection or connectionless stream having the same source
host, destination host, class of service, and session identification
information model: formal representation of real-world objects and concepts, with associated relationships,
constraints, rules, and operations, used to specify semantics in a given domain
NOTE: It includes things of interest (entities), relationships between these entities (associations), and
details/characteristics of these entities (attributes). An information model provides formalism to the
description of a problem domain without constraining how that description is mapped to an actual
implementation in software. The possible mappings of the information model are the data models (see
also RFC 3444 [i.15]).

10 ETSI TS 102 672 V1.1.1 (2009-11)
management plane: provides two types of functions, namely layer management and plane management functions:
• plane management functions: performs management functions related to a system as a whole and provides
co-ordination between all the planes. Plane management has no layered structure.
• layer management functions: performs management functions (e.g. meta-signalling) relating to resources
and parameters residing in its protocol entities. Layer Management handles the Operation And Maintenance
(OAM) of information flows specific to the layer concerned.
Management Information Base (MIB): virtual information store containing managed objects
NOTE: Objects in the MIB (identified by their OIDs) are essentially variables, and are typically defined using
Abstract Syntax Notation One format (ASN.1).
Manager: entity that acts in a managing role
Network Control Centre (NCC): equipment that controls the access of terminals at the lower protocol layers (OSI
Layer 2 and below) to a BSM network
Network Management Centre (NMC: equipment that manages the lower protocol layers (OSI Layer 2 and below) of
a BSM network
Network Management System (NMS): equipment that manages a network at several or all protocol layers
Next Generation Network (NGN): (from ITU-T Recommendation Y.2001 [i.31]) packet-based network able to
provide telecommunication services and able to make use of multiple broadband, QoS-enabled transport technologies
and in which service-related functions are independent from underlying transport-related technologies
NOTE: It offers unrestricted access by users to different service providers. It enables unfettered access for users
to networks and to competing service providers and/or services of their choice. It supports generalized
mobility which will allow consistent and ubiquitous provision of services to users.
Next Generation Operations Support System (NGOSS): Telecommunications Management Forum's (TMF's) core
framework for developing, procuring and deploying operational and business support systems and software
NOTE: The term is also used elsewhere e.g. as the basis for TISPAN OSS standards.
Operations Support System (OSS): generic term for a suite of management functions that enable an enterprise to
monitor, analyse and manage systems, resources and services
Service Level Agreement (SLA) (SP and ANO): SLA between a Service Provider and an Access Network Operator is
usually characterized by a forward link guaranteed capacity for SP aggregated traffic expressed in kb/s and a return link
guaranteed capacity for SP aggregated traffic expressed in kb/s
NOTE: It can also include other elements related to traffic policy and availability.
Service Level Agreement (SLA) (Subscriber and Service Provider): SLA between a SP and its subscriber is
characterised by the choice of one data transfer capability and the allocation attribute related to this transfer capability
NOTE: The SLA is agreed upon by the subscriber at the initiation of the contract with the SP and will remain the
same for all the contract duration.
Service-Oriented Architecture (SOA): (ITU-T) Service-Oriented Architecture (SOA) is a software architecture of
services, policies, practices and frameworks in which components can be reused and repurposed rapidly in order to
achieve shared and new functionality
NOTE: This enables rapid and economical implementation in response to new requirements thus ensuring that
services respond to perceived user needs. SOA uses the object-oriented principle of encapsulation in
which entities are accessible only through interfaces and where those entities are connected by
well-defined interface agreements or contracts.
user: entity that uses the network services requested by the subscriber
user plane: layered structure and provides user information transfer, along with associated controls (e.g. flow control,
recovery from errors, etc.)
