ITU has agreed on updates to its widely deployed optical transport network (OTN) standards, including ITU-T G.709. The revisions provide mapping of a recently launched next generation high-rate Ethernet standard from IEEE into the OTN.

Collaboration between ITU-T Study Group 15 and the IEEE P802.3ba 40Gb/s and 100Gb/s Ethernet Task Force ensured that these new Ethernet rates are transportable over optical transport networks.

Malcolm Johnson, Director, ITU Telecommunication Standardization Bureau:  “Ethernet has evolved from the local area network of choice to become a real carrier grade solution. Co-hosted meetings and workshops, and a recognition that close collaboration was mutually beneficial, has led IEEE and ITU to agree a common mapping between the IEEE P802.3ba 40Gb/s and 100Gb/s standard and the ITU-T G.709 optical network standard. I have no doubt that the scalability provided by this excellent example of standards collaboration will see an acceleration in end-to-end Ethernet deployment.”

ITU-T Recommendation G.709 “Interfaces for the Optical Transport Network (OTN)” describes a means of communicating data over an optical network. It is a standardized method for transparent transport of services over optical wavelengths in dense wave division multiplexing (DWDM) systems.

Operators are facing challenges with the migration from traditional SDH/SONET to IP/Ethernet based services. ITU-T G.709 OTN is a vehicle to enable convergence, and for providing a common and SONET/SDH-like operational model for network administration, performance monitoring and fault isolation, without altering the individual services.

Using OTN, multiple networks and services such as legacy SONET/SDH, Ethernet, storage protocols and video can all be combined onto a common infrastructure.

Most importantly, unlike SONET/SDH, OTN is the only transport layer in the industry that can carry a full 10/40/100 Gb/s Ethernet signal from IP/Ethernet switches and routers at full bandwidth. With the rapid migration towards IP/Ethernet-based infrastructure, OTN becomes the transport layer of choice for network operators.

Sterling Perrin, Senior Analyst, Heavy Reading: “Heavy Reading network operator surveys have consistently shown strong and immediate operator demand for 100 Gigabit Ethernet, driven by the rapid increase in global IP traffic and exhaustion of existing 10 Gigabit networks. The collaboration by these two standards bodies, and the resulting standard, is exactly what the telecom industry needs to bring the next generation of Ethernet transmission to market. Heavy Reading fully expects this announcement to drive rapid market adoption.”

The amendment to ITU-T G.709 is part of a set of revisions that provide for interworking with the new Ethernet standard. Equipment functions that perform the mapping are part of revised ITU-T G.798, equipment management functions are part of revised ITU-T G.874, and the jitter characteristics of this (and other) mapping(s) are in revised ITU-T G.8251.

A paper that outlines more technical detail related to this announceent can be found below.

John D’Ambrosia, Chair, IEEE P802.3ba Task Force Director: “Developing the next generation of Ethernet required consideration of the entire eco-system in which it resides.  Communications between the IEEE and ITU-T addressed the issues that would impact the end-to-end Ethernet deployment.  This interaction led to the two bodies developing standards that complement each other in order to ensure the optimal solution for 40GbE and 100GbE.  I would like to express my gratitude to the ITU-T for its co-operative efforts with the IEEE P802.3ba Task Force.  Furthermore, I would like to congratulate the ITU-T on the completion of its G.709 specification, which is part of the optimized 40GbE and 100GbE end-to-end solution.”

ITU together World Standards Cooperation (WSC) partners ISO and IEC will hold its first-ever Academic Week 5-9 July 2010 in Geneva, Switzerland. The event is intended to raise awareness of the importance of including standardization in programmes of higher education because of its roles in facilitating access to world markets, transferring technology and promoting good business practice and sustainable development.

A knowledge of standardization and the benefits it can bring to business, government and society as a whole is increasingly being seen as part of the essential "baggage" of future managers in both public and private sectors.

An impressive list of speakers from academia, industry and national and international standards bodies will provide insight on these matters and stimulate discussions, with a view to promote the dialogue and to foster cooperation between academic institutions and the International Standards community.

The WSC is the strategic coordination entity of the world's leading standardization organizations – the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU).

The three partners recognize the fundamental contribution that educational institutions can make in teaching the value of international standardization, appreciate how the work of academia on the cutting edge of research and technology can benefit the development of standards and are keen to support these institutions in their efforts.

The annual workshop of the International Cooperation on Education about Standardization (ICES) – a network of individuals and organizations interested in education about standardization – will also take place during the week.

The event is being held at the International Conference Centre, Geneva, and programme comprises:
5-6 July, ICES workshop
7 July, Recognizing academic excellence
8 July, Cooperation between international standardization organizations and academic institutions (including participation by the Rector of the University of Geneva and representatives of the Ecole Polytechnique Fédérale de Lausanne (EPFL) and the University of Lausanne)
9 July, Economic and social benefits of standards.

ITU’s first interoperability event on IPTV will be held at ITU headquarters, Geneva, 20 to 23 July 2010. Testing will take place 20 and 21 July, with vendors showcasing interoperability to potential customers 22 and 23 July.  The event will demonstrate the state of maturity and industry adoption of ITU-T standards for IPTV, for example: H.701 (error-recovery), H.721 (IPTV terminal), H.740 (audience measurement), H.750 (metadata), H.761 (ginga-NCL), H.762 (lightweight interactive multimedia), H.770 (service discovery). Many companies - manufacturers of set top boxes, content servers and other equipment - have expressed interest in testing and showcasing their products, including from Belgium, Brazil, China, France, Japan, Singapore, South Korea and the United States. To register, go to:

IPTV is a major business opportunity for telcos, content providers and existing broadcasters. ITU-T’s IPTV standards are being incorporated in product offerings from vendors and service providers around the world. The standards cover a wide range of topics including interactive services, content location, terminal specifications, metadata and QoS.  Companies from Brazil, China, Japan, Korea, France, and elsewhere have implemented ITU-T's IPTV standards and sell in the open market as TV and set top box products. In China and Japan, ITU-T IPTV is already deployed with several million subscribers. A test service is being conducted in Singapore, and there is interest in having test beds in India and Canada.

ITU-T interoperability events on IPTV seek to address issues of conformance and interoperability.  ITU’s IPTV standards – developed under ITU’s IPTV Global Standards Initiative (IPTV-GSI)  - take into account various aspects of technologies, including IPR, maturity, stability and market adoption. Since ITU-T IPTV is based on mature technologies, decided by consensus, interoperability is easy among different vendors. ITU-T standards include many new features modeled on web technologies, and thus provide the rich interactivity and usability which has become a characteristic of today's ICT service.  

Future IPTV Interop Events are planned for Singapore in September and India in December.  Future Interop events may include: Home Networking; VDSL2 and GPON (Gigabit-capable Passive Optical Network).

Guidelines regarding principles that telecommunications operators may wish to consider to manage financial disputes have been approved by ITU members. A report produced by ITU and the World Bank in 2004 stated: “Disputes can be enormously destructive to the sector and effective dispute resolution is increasingly central to successful deployment of modern information infrastructure. This is particularly so where it is necessary to encourage investment and competition to reach the underserved billions of people on the wrong side of the digital divide.”

Dr. Kishik Park, Chairman of the ITU-T Study Group 3 that has produced the documents said: “Successful dispute resolution is important for all countries that seek to facilitate the rapid expansion of new communications infrastructure and ICT services. It is particularly crucial for countries that have historically experienced a lack of investment and growth. Rapid and effective resolution of disputes is one of key elements in bridging the “digital divide”.”

The documents are supplements to the current ITU-T Recommendation D.170 on General Tariff Principles.

The first supplement is intended to assist telecommunication carriers in the development of efficient processes that might be used to resolve disputes in international settlements. Before a dispute can be raised, parties should have agreed to a reconciliation or dispute criteria and such criteria should preferably be specified in the signed agreement or contract. The supplement is focused on revenue and costs assurance and it mitigates any revenue and/or cost-related issues. It describes the details of the criteria which may be taken into consideration before raising and verification of any dispute, possible sources of dispute, and determination of validity of dispute or discrepancy.

The supplement also provides guidance on managing the resolution of disputes resulting from poor reference data maintenance (rate discrepancy, destination or dial code) and transactional data (recovery rate shortfall, volume discrepancy, time zones differences, calls crossing midnight and one month to the next, negative declarations, double counting, volume committed agreements, reverse charged calls, call durations, etc). It also describes a method of call data record (CDR) exchange, a comparison process and how to proceed with unresolved disputes.

The second supplement presents guidelines for process and proposition of dispute forms for international settlements. It may help to simplify and assist telecommunication carriers in proper and fast resolution of any kind of financial dispute. The exact nature of the dispute resolution should be agreed in the bilateral arrangements between the carriers concerned.

The supplement describes the whole process, details possible reasons and sources of financial disputes and advices how to investigate and handle with them. The supplement is intended to provide carriers with information regarding possible procedures and example forms for use in the dispute resolution process. These processes may help save time and human labour as well improves bilateral business relations between partners.
