Newslog has news on a new ITU-T standard (ITU-T Recommendation, Y.1731) which will
allow operators offering Ethernet services to use OAM (operations, administration, and
maintenance) mechanisms to facilitate network operation and troubleshooting.
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.
