Geneva, 28 February 2011 – In a big step towards leveraging existing MPLS (Multiprotocol Label Switching) deployment in transport networks, ITU has agreed first stage approval of a key new standard. The ITU-T standard will give network operators the tools necessary to manage large scale deployments of MPLS-based networks. Network operators will now have a choice of OAM (operations, administration and maintenance) tools to best meet their specific transport network requirements. These OAM tools in the hands of network operators will, in particular, allow quick detection of defects and fault isolation.

MPLS is widely embraced in backbone networks as a way to speed up routers. The OAM tools in the ITU-T standard are based on technology proven in carrier grade Ethernet services and legacy transport networks, making it easier for operators to upgrade. In addition to reducing labour costs, network operators will see significantly reduced capital expenditure (CAPEX) costs given that the standard allows for more efficient allocation of bandwidth.

Operators are increasingly looking to MPLS as an end-to-end technology, given its inherent flexibility and support for IP-based applications. The decision was taken together with first stage approval of another standard providing network architecture for MPLS-TP based networks.

Dr Hamadoun Touré, ITU Secretary-General, said: “ITU collaborates and coordinates, in good faith and on the basis of reciprocity, with other relevant organizations in the development of IP networks to ensure maximum benefits to the global community. This is in accordance with the decisions of the 2010 ITU Plenipotentiary Conference. However, this should not lead to a situation where the ITU fails to deliver on its commitments to its own membership. Much effort was made to reach a compromise during last week’s Study Group 15 (SG15) meeting, but the decision was taken very exceptionally by vote, since all attempts at compromise had failed.”

ITU-T SG15 began working on transport profiles for MPLS technology suitable for use in the network layer of transport networks more than three years ago. A joint working team (JWT) was set up to allow Internet Engineering Taskforce (IETF) and ITU experts to work together to avoid divergent work streams. Specifically, it was expected that this group would provide the necessary protocol extensions for ITU’s specifications to work in an MPLS environment. IETF committed to provide its contribution by the second quarter of 2009. However this crucial technical input was not provided and the IETF’s MPLS-TP Interoperability Design Team (MEAD) was unilaterally disbanded by IETF in October 2009.

Malcolm Johnson, Director, Telecommunication Standardization Bureau, ITU: “ITU is a consensus based organization and voting is always a last resort. In this case it was clear that a significant part of our membership could not accept any further delay in pursuing a solution that will give them the ability to address a real market need. Given that there are over 100,000 MPLS-TP nodes already in transport networks, it is essential that the corresponding OAM tool.

ITU-T NGN expert, Seungyun Lee, from the Korean Electronics and Telecommunications Research Institute (Korea) will make a presentation at the upcoming Telemanagement Forum’s (TMF), Service Delivery Summit. Lee’s presentation is entitled Towards a SOA/WS enabled NGN Open Service Environment - ongoing developments in ITU-T SG13.

His abstract:

“Across the telecom industry, much work is underway to separate the communications capabilities in today’s networks from the networks themselves and to make those capabilities available for integration into the applications in the IT industry. This effort is making possible a rich menu of modular building blocks that can be easily mixed and matched with building blocks from the IT industry to form wholly new kinds of multimedia services and automated business processes that marry the rich content, data applications, and business processes of the IT world with the intelligent, real-time, in-the-network functions of the telecom domain.

Key to this effort at the core of future multimedia service architectures are the SOA (Service Oriented Architecture) and the WS (Web Services) frameworks. ITU-T SG13 has started the development of specifications towards the integration of SOA and WS technical approaches in the NGN context. In line with approved and ongoing ITU-T recommendations, this presentation, building over the basic concept of NGN capabilities, will introduce some key requirements and capabilities for the support of an advanced open service environment in NGN. The integration of SOA and WS in NGN will be then examined, including some achievements and current challenges for the standards community.”

The event focuses on the drive to create an open, industry owned blueprint of how new and exciting services can be created and delivered across complex value chains. It examines standardization of key elements of service delivery platforms (SDPs), which will open up the ability of partners to add end-user value by working seamlessly together to deliver novel services, created and delivered in a fraction of the time and cost it takes today, while dramatically cutting integration costs and avoiding vendor lock-in.

A call for papers has been issued for the 10th Asia-Pacific Network Operations and Management Symposium (APNOMS 2007).


The event will be held in Sapporo, Japan from October 10 to 12, 2007 with the theme “Managing Next Generation Networks and Services.”

From the call for papers: “Recently, various convergences in wired and wireless networks, and convergence of telecommunications and broadcastings are taking place for ubiquitous multimedia service provisioning. For example, broadband IP/MPLS wired networks are actively converged with IEEE 802.11e wireless LAN, IEEE 802.16 Wireless MAN, 3G/4G wireless cellular networks, and direct multimedia broadcast (DMB) network. For efficient support of service provisioning for ubiquitous multimedia services on the broadband convergence networks, well-designed and implemented network operations and management functions with QoS-guaranteed traffic engineering are essential.”

“In APNOMS 2007, the topics of interest include, but not limited to, network & service management for broadband convergence networks, business operations & management, service-oriented managements (e.g., SLA/SLS, security, billing), management architecture and technologies, various experiences, and recent standardization activities.”

Study Group 4 has consented a set of Recommendations on data definitions for terminal users of operational support systems. These definitions will allow operators to communicate more efficiently on operational matters, such as service orders and orders about network routing arrangements.

According to developers of the Global Telecommunications Data Dictionary (GTDD) (ITU-T Recommendations M.1401-10), the data definitions use an approach that is different from current conceptual approaches to define data communication interfaces. The GTDD approach will be more intuitive for end-users, in this case the operations staff in telcos.

The data definitions given in the GTDD may be used to develop XML schemas for exchange of data about telecoms networks and services between network operators. The GTDD defines data for end user interfaces and supports data communication to/from management applications.

Experts said that much of the data needed by NGN is defined not only for management but also for the execution of services. Definition of service management is critical for NGN, because it deals with interfaces that will be used by service platforms like IMS. Another use for GTDD is inventory management experts said.

Study Group 13 will publish a Recommendation that acts as an umbrella to progress work on all aspects of multiprotocol label switching (MPLS) management. 

MPLS is seen as an important way to simplify traffic engineering in NGN. ITU-T Recommendation Y.1714 provides a framework for management and operation administration maintenance (OAM) in MPLS. OAM mechanisms facilitate network operation and troubleshooting. Standards-based OAM features that will allow for interoperability between different vendors are seen as a requirement for carriers adopting MPLS.

Referring to the telecommunication management network (TMN) model developed by ITU-T’s Study Group 4, the Recommendation’s scope is limited to those components and interfaces that interface between network elements (user and control plane), and between network elements and element management system (EMS) and network management system (NMS).

ITU-T Recommendation M.3343 consented at the Beijing meeting of Study Group 4 outlines the requirements and protocol neutral information model necessary to communicate trouble tickets in a multi-service provider NGN environment.

NGN according to the Recommendation introduces new reporting needs to address new service types expected.

The Recommendation describes a trouble in a communications network as a problem that has an adverse effect on the quality of service perceived by network users. Management of trouble tickets is necessary to ensure that they receive attention and that the trouble is cleared to restore the service.

At the time of a trouble, a network may have been inter-working with another network to provide a service. Therefore a standardized way of exchanging trouble management information between management systems across interfaces is necessary.

Study Group 4 saw the consent of a Recommendation (M.3342) which provides the means to document service level agreements (SLA) between a service customer and a service provider.

The Rec. takes into account the fact that NGN demands QoS guarantees for services. SLAs are considered an effective way of solving the problems of QoS guarantee between customers and providers. The Recommendation describes the detailed classification of SLA content, provides guidelines and instructions for the definition and composition of ‘SLA representation templates’ in order to manage QoS and service guarantees more effectively. It also includes instructions on how to complete the templates.

Study Group 13 will start work on a new topic (Question) relating to commercial off-the-shelf software (COTS).

COTS solutions are seen as an efficient way to reduce operating costs, but a lack of standards has kept costs high for licensing, adapting and integrating these components.

The title of the new Question will be Requirements and framework for enabling COTS components in an open environment. The aim is to outline the open interfaces and standards required to deploy COTS solutions in NGNs.

According to the text of the Question: “Guidance is required to ensure that COTS components will allow for creation of open and integrated communications platforms consistent with open (public and non-proprietary) standards  such that they will accelerate deployment of NGN infrastructure and services. It is necessary to define a common approach that helps to navigate through the appropriate interfaces and options to deliver an open and integrated communications platform using these standards.”

The Question was set up following a proposal from the Focus Group, The Open Communications Architecture Forum (OCAF). A Rapporteur, Johannes Prade, has been provisionally appointed to lead this work.

A review by the Telecommunication Standardization Advisory Group (TSAG) is necessary to complete the formal approval of the Question at the next Study Group 13 meeting in July 2006, but work in the area is ongoing and will continue as normal.

At the same meeting of SG 13, OCAF submitted two draft Recommendations, The carrier grade open environment reference model and Carrier Grade Open Environment Components. It is expected that these will be sent for consent at SG 13’s next meeting.

A new ITU-T standard (Recommendation) will allow operators offering Ethernet services to use operations, administration, and maintenance (OAM) mechanisms to facilitate network operation and troubleshooting.

Given that performance management has been cited as a major concern of operators looking at Ethernet as an end-to-end solution, and that OAM features are not standard in Ethernet, it is seen as crucial to provide this facility. Standards-based OAM features that will allow for interoperability between different vendors are seen as a requirement for carriers adopting Ethernet on a wide scale. Experts say that operator deployments may start in 2007.

Ethernet services are becoming popular because they allow carriers to offer considerably improved flexibility to customers through a much simpler and lower cost interface. Ethernet allows users to specify exactly how much bandwidth they want between the 10Mbit/s and 1Gbit/s range currently offered. Further, Ethernet provides reduced operation complexity and improved scalability for carriers.

And as operators look to NGN and the use of the Internet Protocol (IP), Ethernet is seen as the best fit, especially given the rise of such services as IP VPNs, VLANs and dedicated Internet access. Equally this OAM functionality may be deployed in a local area network (LAN).

The ITU-T Recommendation, Y.1731 consented at the recent meeting of Study Group 13, identifies the OAM functions which are needed to allow fault management (fault localization, defect detection, etc.) and performance monitoring (error counts, delay measurement, etc.) in an Ethernet network. With regards to performance monitoring, the Recommendation only addresses point to point connectivity today, says Gilles Joncour, ITU-T Rapporteur for the Recommendation, (multi)point to multipoint will be the next step.

Joncour gives some more detail: ‘’Y.1731 also specifies the so called OAM PDUs (protocol data units) which constitute the payload of the Ethernet OAM frames. The content (fields) of the PDUs vary according to the function(s) they correspond to. Y.1731 does not specify the processes associated to the sending, reception and analysis (of the content) of the OAM frames/PDUs. This will be part of another Recommendation (G.8021), from Study Group 15. Y.1731 specifies methods for measuring sample values of parameters identified for monitoring the performance of Ethernet networks. It does not deal with the integration of those values over a period of time and the use of such results, when applicable for defect detection. This will also be done in G.8021.”

Recommendation Y.1713 gives user-plane OAM functionality in Ethernet networks. The architectural basis for this Recommendation is the Ethernet specification G.8010. A previous Recommendation Y.1730 served as a prelude to Y.1731 outlining the OAM requirements of operators. Joncour says that Y.1731 was developed in close collaboration with the Institute of Electrical and Electronics Engineers (IEEE) group 802.1. This group is also preparing a standard (802.1ag - Connectivity Fault Management) devoted to Ethernet OAM aspects. IEEE 802.1ag defines a subset of the functions/PDUs described in Y.1731. Regular communications between the two groups ensured alignment of the description of the common features.

The third meeting of the Service and Network Operations group (SNO) will be held 20 March - 24 March 2006 at the Sandton Convention Centre, Johannesburg, South Africa at the kind invitation of Telkom SA Ltd.

SNO is a group that operates under the auspices of ITU-T aiming to address issues in network management as encountered by network operators throughout the world. It was formerly known as the Network Management Development Group (NMDG).

As "the Voice of Operations", the group has had a direct impact on existing and new ITU-T Recommendations in the field.

This SNO event aims to provide an opportunity for an open communications sharing experience among international network operators. In addition the conference aims to encourage wider global ITU-T participation in the identification, development and implementation of network and service management activities for operations.

Registration and general information can be found here.

A roadmap identifying NGN management specifications has been published on the ITU-T SG 4 website.

The roadmap will provide an insight into how NGN management will differ from the management of traditional telecommunication. And as specifications are added this picture will become clearer, experts said.

The NGN Management Specification Roadmap is an output of the NGN Management Focus Group, a group sponsored by ITU-T SG 4. The document identifies the various existing, or work-in-progress specifications relevant to NGN management. These specifications are not all ITU-T Recommendations, but also come from other standards making bodies with expertise in defining management interfaces. For example, the roadmap tags the 3GPP (3rd Generation Partnership Project) specs for mobile telephony relevant to the IMS (IP Multimedia Subsystem) management. IMS is expected to be a key building block for NGN specifications.

An additional and important feature of the document is that it provides gap analysis, identifying areas where standards are still needed, and also identifies overlapping specifications requiring harmonization.

The aim is for the roadmap to be a living document at this time, which is part of the reason that it hasn’t been turned into an official ITU document – like a Recommendation. Another reason for not giving the document ‘normative’ status is so that non-members can enjoy free access to it.

Work on a standard (ITU-T Recommendation) that updates telecommunication management principles for NGN has been completed in Study Group 4.

Standards here are essential according to SG experts in order to ensure that management solutions support NGN, a network based on the separation of service and transport capabilities.

The work focusing on the interfaces between management systems was mostly led by service providers and is important in order for the dynamic provisioning of services in NGN. The document will also allow for easier planning, installation, maintenance, operation and administration experts say.

The Recommendation - M.3060 - was consented with input from other standards bodies including 3GPP, ATIS, ETSI and the Telemanagement Forum (TMF). It presents the telecommunication management principles, including requirements and four architectural views for managing NGN based on service-oriented architectural concepts.

Study Group 4 meets this week in Geneva. The Study Group looks at the interfaces that sit between management systems and network elements, as well as interfaces between management systems.

Dave Sidor, Chairman of SG 4 said prior to the meeting, a key focus will be progressing NGN related specifications and also harmonization of standardization efforts across different standards making bodies. Sidor said that it’s important to identify the overlaps between these bodies in order to avoid duplication of work and ensure that industry’s best needs are served. In this way he said industry ends up with one rather than multiple solutions.

One area that will be discussed in terms of this harmonization is the charging and billing for services in next-generation networks (NGN). Another is in the area of specifications for management of Ethernet based networks.

For possible consent at the meeting is M.3060, a proposed ITU-T Recommendation covering the principles of NGN management.

Also at the meeting the NGN Management Focus Group will report on its activities in particular on the NGN management specification roadmap, a document which identifies the various existing, or work-in-progress specifications for NGN management. These specifications are not necessarily ITU-T Recommendations, but could come from any other standards making body.

The Focus Group on next-generation networks (FGNGN) has recently completed a technical report that will hand back some elements of network management to the customer.

The document is an approved deliverable of the group that will be submitted to FGNGN’s parent within ITU-T, Study Group 13, for further consideration as a candidate ITU-T product (e.g. Recommendation, supplement, handbook, etc.). It outlines a framework for customer manageable IP networks (CMIP).

CMIP will give end users the ability to manage network elements and resources, such as bandwidth and storage.

Using a menu driven system CMIP will allow end-users to split bandwidth, dedicating, for instance, 1 Mbps to file sharing, .5 Mbps to instant messaging and e-mail, and .5 Mbps to web browsing.

Service providers will benefit by being able to offer this ability as value-add to their Internet service offerings, and will also be able to better provision network resources for services, such as web browsing, VoIP, and peer to peer (P2P), given the increased knowledge of exactly how users are using their bandwidth.

A recent meeting of Study Group 4 saw the completion of one Focus Group’s work and the start of another’s. Both achievements are a result of the formal relationship between the standardization sector of ITU and the Telemanagement Forum (TM Forum).

The Telecommunication Management Collaboration Focus Group for Human Machine Interface (HMI) comprised of members of the TM Forum and Study Group 4 has completed its activities, inputting its work into SG4 for progression into ITU-T Recommendations. Recommendation Z.371 deals with the graphical user interfaces and information requirements for displaying telecommunications objects such as links and nodes, while Recommendation Z.372 provides patterns for the design of the HMI templates for object browsers.

As management systems and network elements have become more complex, telecommunication network operators have demanded improved and standardized HMIs. This they believe will allow them to increase quality of service and reduce response times to customers.

Following the success of this Focus Group, another on Multi-Technology Network Management has been set up in Study Group 4. This group will look to further standardize management interfaces, this time machine to machine. Specifically the group will examine the interfaces for managing transport networks and their elements, for technologies such as SONET/SDH, DWDM, ATM, Frame Relay, Ethernet and DSL.

Study Group 4 recently consented a series of Recommendations which specify the security  requirements, services, and mechanisms for the management plane.

More specifically, the standards (the M.3016.x series of ITU-T Recommendations) support the ability to provide secure communication of management information across interfaces between network elements and management systems and also interfaces between management systems. In addition, the specifications also apply to the administration of the management systems themselves.

SG4 Chairman Dave Sidor says that this work is an important part of ITU-T's ongoing NGN activity.

The standards have been designed to allow tailoring by other management standards organizations to meet their regional, national, or specific-technology needs. This feature is supported by M.3016.4, Profile Proforma.

Recommendations in the series include:
M.3016.0 – Security for the Management Plane: Overview
M.3016.1 – Security for the Management Plane: Security Requirements
M.3016.2 – Security for the Management Plane: Security Services
M.3016.3 – Security for the Management Plane: Security Mechanisms
M.3016.4 – Security for the Management Plane: Profile Proforma
