Title:
A METHOD FOR TRANSPARENT TRANSMITTING 10GE ETHERNET SIGNAL THROUGH THE OPTICAL TRANSPORT NETWORK
Document Type and Number:
WIPO Patent Application WO/2009/065281
Kind Code:
A1
Abstract:
A method for transparent transmitting 10GE Ethernet signal through the optical
transport network is disclosed, the method uses the first asynchronous mapping
manner for transparent transmitting 10GE Ethernet signal; wherein, the construction
of the first asynchronous mapping manner includes the following steps: A1, a
reserved value of anyone of the payload structure identifiers is used to indicate
the first asynchronous mapping manner; A2, the optical channel transport unit-frame
of the first asynchronous mapping manner is constructed, in the adjusting and
controlling bytes, at least three bits are used to pre-define the filling state
of the positive/negative adjusting bytes, and a negative adjusting byte is added
in the overhead zone of the payload unit in the optical channel, a positive adjusting
byte is added in the payload structure unit; A3, a reference clock is used in constructing
the overclock optical channel transport unit-frame, the frequency is 11.0491Gbit/s±20ppm.
Using the above solution, the integrated 10GE LAN signal can be transparent transported
in the asynchronous mapping manner through the optical transport network, the
frequency deviation of the client signal is well adapted.
