Does anybody know of any stds for direct IP mapping into a SONET/SDH
payload (SPE) ? Thanks in advance.
That question probably should be addressed to T1X1.5, which is the
ANSI-accredited subcommittee with the charter to define SONET payload
mappings. As far as I am aware, there is nothing currently standardized
nor any ongoing work regarding a direct mapping of IP. I believe that
the closest thing now standardized is the HDLC-over-SONET mapping that
is used for PPP over SONET (see RFC 2615) and frame relay over SONET.
There was some recent work on defining an Ethernet-over-SONET mapping,
but I don't know its status. For further information check the T1X1.5
file archive on the committee T1 web site at http://www.t1.org/.
