HI
I want to share some information about configuring 10G services in differenet forms in DWDM network
1.What are the differences between 10GE LAN and 10GE WAN services?
According to IEEE 802.3ae, compared with 10GE LAN services,10GE WAN services involve an additional process in which signals are
encapsulated into standard SDH/SONET frames. In other words, 10GE WAN services are processed in a similar way as how STM-64
services are processed in a WDM/OTN system.The most direct difference between 10GE LAN and 10GE WAN services is that they have different signal rates.
2.How do we configure 10GE LAN and 10GE WAN services?
Let's take a look at the steps for configuring 10GE WAN services.
3 - About the 10G LAN there are 2 types of port mapping ((bit transparent mapping and MAC transparent mapping))
What is the difference between bit transparent mapping and MAC transparent mapping?
In bit transparent mapping (11.1G) mode, the OTU frame frequency is increased to ensure the encoding gain and error correction capability of the FEC function.Therefore, the service rate is OTU2e,which is higher than OTU2. This mapping mode is recommended for interconnection between Huawei devices.
In MAC transparent mapping (10.7G) mode, the GFP-F encapsulation mode is used to map 10GE MAC frames into OTU2 signals.
This mapping mode provides a standard service rate and therefore facilitates interconnection between Huawei devices and peer devices.
I hope that will be be useful to all .
