New Standard on
Transport of Internet Protocol (IP) over Asynchronous Transfer
Mode (ATM) in Public Networks |
Geneva – The International Telecommunication Union has approved an
important new standard specifying the transport of Internet
Protocol (IP) structured signals over Public Networks based on
the Asynchronous Transfer Mode (ATM) technology.
The ITU, a United Nations agency,
coordinates the development of global communications standards.
Study Group 13 of the ITU Telecommunications Standardisation
Sector (ITU-T), where work on this specification has been
carried out, is the lead Study Group on IP-related standards
activities responsible for standards development in the area of
general network aspects.
The new standard, ITU-T Recommendation Y.1310 ‘Transport of IP
over ATM in Public Networks’ was approved at the Study Group
13 meeting held in Kyoto in February/March 2000.
“This important new standard was achieved through the cooperation of
all industry sectors and incorporates selected protocols
developed by the ISOC/IETF. The new standard provides a common
basis for interworking Internet and IP-based applications
between different networks and different vendors in the public
domain”, said Mr. Brian Moore, chairman of ITU-T Study Group
13.
Recommendation Y.1310 is the second major IP-related standard
issued by ITU-T Study Group 13. Last year the Study Group completed Recommendation
Y.1540, which defines performance parameters for quantifying IP
network performance. This will be followed quickly by Y.1541
which will define quality of service classes and performance
objectives that should be achieved by IP network
providers in assuring the end-to-end performance of IP
communications.
These new standards are a major step
forward for the ITU-T in moving telecommunications networks
towards integration with the Internet, and other IP-based
networks, to improve global opportunities for integrated voice,
data, image and video communication.
The standards are part of a Y-Series of Recommendations devoted
to IP-related issues including architecture, access, transport,
performance and signalling aspects.
At the Kyoto meeting Study Group 13 also approved new
Recommendations on Information Communication Architecture,
inverse multiplexing for ATM, ATM over physical links in mobile
radio access networks, error performance of synchronous digital
transmission systems and protection switching.
