Networking vendor Ciena has announced plans to deploy 100 Gigabits per second (Gb/s) Ethernet network equipment to connect NYSE Euronext’s New York and London datacenters. The equipment will connect the respective trading floors over a single optical wavelength with the lowest latency possible.
 
Expected to be operational in 2010, the network equipment will make use of an upcoming extension of ITU-T G.709/Y.1331 currently under discussion in Study Group 15, ITU-T’s Study Group on optical transport networks and access network infrastructures.

G.709/Y.1331 defines “Interfaces for the Optical Transport Network (OTN)”. OTN is presently offered at three bit rates, OTU1 (~2.7 Gb/s), OTU2 (~10.7 Gb/s) and OTU3 (~43 Gb/s), where the latter corresponds to the highest bandwidth on a single wavelength commercially deployed today.

OTU4 will define a transport interface capable of carrying the 100 Gigabit Ethernet client signal studied in IEEE’s P802.3ba 40 Gb/s and 100 Gb/s Ethernet Task Force.

Also see background papers by NORDUnet, Nortel and NTT describing the transition to 100G and the related standardization activities.

A two day Forum on Implementation of decisions of the World Telecommunication Standardization Assembly-08 (WTSA-08) will take place in Accra, Ghana, 16 to 17 June 2009.

The event hosted by the Ministry of Communications, Ghana will review WTSA-08 results from an African perspective and consider how to implement those Resolutions that are of interest to the region. Participants will share experiences in order to identify areas of cooperation and to establish priorities and an action plan to ensure that they gain most benefit from the WTSA-08 Resolutions.

Leading representatives from governments, regulators, industry and academia will join with operators and service providers from the African region. Key topics to be discussed include conformity and interoperability testing, IP-based networks, misappropriation of numbering resources, cybersecurity initiatives, IPv6 and CIRTs. 

Other topics include environment and climate change, accessibility, measurement concerns related to human exposure to electromagnetic fields, and emergency communications.

The Telecommunication Standardization Advisory Group (TSAG) concluding its three day meeting 30 April agreed on how work on ICTs and environment including climate change and recycling will be distributed in ITU-T. This follows its approval of the report of the Focus Group on ICTs and Climate Change and will formalize the Focus Group’s output as ITU-T Recommendations (see previous newslog) – including a methodology for evaluating the effects of ICTs on climate change - both in direct terms and how ICTs can reduce emission in other industry sectors.

Study Group 5 was chosen as the lead study group and will be renamed the Study Group on Environment and Climate Change to reflect its new mandate. SG 5 remains the lead Study Group for protection against electromagnetic effects.

Specifically SG 5 will work on documents related to:

  • Study of methodologies for calculating the amount of greenhouse gases (GHG) emissions from ICTs, and the amount of reduction in the GHG emissions in other sectors as a result of using ICTs.
  • Creation of a framework for energy efficiency in the ICT field, taking account of WTSA Resolution 73.
  • Study of methodologies for power feeding that effectively reduce power consumption and resource usage.
  • Study of methodologies that reduce environmental effects for ICT facilities and equipment such as recycling,

Study Group 5 will next meet 25-29 May in Geneva and is likely to establish a new working party to address these issues. The many organisations that contributed to the work of the Focus Group will be open to contribute at the invitation of the Study Group chairman.

In addition a Joint Coordination Activity (JCA) will ensure that the work across ITU-T’s study groups is focused on delivering climate change focused standards in a timely and efficient way. Essentially the group will aim to see that standards are developed in the most appropriate way and that no duplication of effort occurs. It will also provide a single point of contact for ICT and Climate Change activities in ITU-T and seek collaboration from external bodies working in the field. It is expected that the work of the JCA will be carried out mainly via web-conferencing tools.

Full details will be published on the website of Study Group 5 and a soon to be created JCA page.

A new white paper by Polycom highlights “G.719: The First ITU-T Standard for Full-Band Audio”.

Recommendation ITU-T G.719 describes a coding algorithm for conversational speech and audio supporting the full human auditory bandwidth (from 20 Hz to 20 kHz), that is, all sounds that a human can hear.

The paper concludes that “major technical achievements of the G.719 codec are its high quality and low complexity that make it perfect for devices ranging from telephones and low-power mobile devices to soft clients and to high end video and telepresence systems.” First products implementing ITU-T G.719 are expected to appear in 2009/2010.

The standard was developed in Study Group 16, ITU-T’s lead Study Group on multimedia coding, systems and applications, and adopted in June 2008.
