ITU’s recent announcement on an OAM standard for MPLS in transport networks has seen considerable interest, but not always for the right reasons with claims from the Internet Society that it will jeopardize the Internet.

Experts cast doubt on ISOC’s statement: “… ongoing evolution along this path will jeopardize the … Internet”.

They point to the fact that several interoperability tests have been successfully performed with no reported problems. In addition the solution being proposed by ITU conforms to the MPLS-TP architecture as defined by the IETF. When network equipment uses different protocols, interoperability of the functioning of that protocol, in this case OAM, may well be affected. However, since packets for different protocols are identified by pre-assigned different codepoints, protocols running behind these different codepoints will not interfere with each other. This means that the core functionality – in this case Internet traffic – will not be affected. Therefore various protocols can coexist without causing any confusion in the network.

It is also important to understand who has contributed to this standard (draft Recommendation ITU-T G.8113.1) and why. The membership of ITU is made up of representatives from over 700 private sector companies (including most major ICT companies) and 192 Member State governments. In general technical work such as that being discussed here is undertaken by the private sector members. This solution was called for by a majority of the ITU membership in SG15 that has grown frustrated with a lack of progress in the development of a standard which is necessary to meet a market demand. Given that there are over 100,000 MPLS Transport Profile nodes already in transport networks, it is essential that the corresponding OAM toolset is standardized.

As background, in 2006 ITU started work on standards on T-MPLS, which leveraged a sub-set of MPLS that was targeted specifically for application in the transport network. However, in late 2007 the IETF indicated that T-MPLS may be in conflict with IP/MPLS.  The ITU suspended work on T-MPLS and in 2008 agreed to work in cooperation with the IETF on the evolution of MPLS to meet the needs of the transport network. It was anticipated that the five existing Recommendations on T-MPLS would be replaced by mid 2009 with MPLS-TP Recommendations following within a year.

However some of the IETF input (RFCs) required to move forward were not made available and are currently still pending following the unilateral disbanding by the IETF of its group assigned to work with ITU in September 2009.

ITU has issued a formal request for the necessary codepoints from IETF as these codepoints are currently administered by ICANN/IANA and can only be issued by IETF.

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, 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.

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.

It was organized by ITU with IEEE Communications Society as Technical Co-Sponsor and supported by, Cisco, Nokia Siemens Networks and MYFIRE. The Global ICT Standardization Forum for India (GISFI), the ITU-APT Foundation of India, and the CMAI Association of India supported ITU in promoting the event throughout India.

The conference brought together over 435 participants of 26 countries. Among them, the best academic minds from around the world presented their future visions on innovative technologies to challenge the fundamental networking design principles of the Internet. The conference also included an exhibition by local Universities which provided insight into their activities.

In addition to the four invited papers, 37 were presented from the 115 papers submitted, and the best three awarded prizes. The winning papers will also be featured in a future special edition of IEEE Communications Magazine. The consolidated Proceedings of the conference will be soon available at the event’s webpage (http://www.itu.int/ITU-T/uni/kaleidoscope/2010/index.html) and all papers will be downloadable from IEEE Xplore online catalogue shortly.

In addition to the prize pool, ten entrants - Kideok Cho, Rakesh Jha, Pranoti Bansode, Pankaj Chand, Klemen Peternel, Labonnah F. Rahman, Mohammadmajid Hormati, Arnupharp Viratanapanu, Rahamatullah Khondoker, and Muzahid Hussain - received a Young Author Recognition Certificate.

For the first time, this year’s Kaleidoscope event saw a new feature; Jules Verne's corner. The session is dedicated to visionaries, science fiction writers, journalists, movie directors and anybody else who is able to imagine an unpredictable future, putting forward inspiring, revolutionary ideas. Structured as a panel session the speakers were: Eduard Babulak, European Commission; Mitsuji Matsumoto, Waseda University, Japan; Rahul Sinha, Illinois Institute of Technology, USA; Daniele Trinchero, Politecnico di Torino, Italy and Simao Campos of ITU. Topics covered included future internet networks; the mapping of signals in a dense wireless four-dimensional space-time domain; the detection of information from the brain by analyzing activities of neurons and facing their “time-variable” characteristics and a “Rigorous Pseudo Scientific Demonstration” of time machines.

For more information and presentations from Kaleidoscope 2010, see the event's web page.

Building on the success of the first, second and third Kaleidoscope events, a fourth conference is planned for end 2011. A call for papers has already been issued for The fully networked human? − Innovations for future networks and services. Through implanted sensors, e-health applications will support senior citizens communicating automatically their medical data to care providers… but what if the information falls into the wrong hands? Modern heating systems at home would be programmed, via hands-free devices, while driving to work… but what happens if this is done via a text message distracting the driver? How can we make increasingly complex devices user-friendly? A call for abstracts for 2011’s Jules Verne’s corner has also been issued under the title The Chip in the Brain.
