Thanks for your comment. Im glad you like it.

Is it possible to add the RMP Model and the MP2MP Model to this description?

The RMP (rooted multipoint) connection supports the E-Tree service and the MP2MP (multipoint to multipoint) connection supports the E-LAN service.

In the "Pipe bandwidth" section it is stated "Rigid and hard pipes". This may be incorrectly understood, given that the OTN supports since 2009 the ODUflex connection. This ODUflex connection can support any bandwidth between 1 and 100 Gbit/s in todays edition of the standard. In the next edition (2016), the ODUflex will be specified to support any bandwidth between 1 Gbit/s and X Tbit/s, in which the value of X is determined by the vendors line card technology (e.g. 400G, 1T, 2T, etc). In case an ODUflex connection is used to carry packets, it is possible to hitless resize the ODUflex connection using the hitless adjustment of ODUflex HAO protocol (see G.7044). Use of an ODUflex connection with a bandwidth lower than 1 Gbit/s is in principle possible, but not described in the OTN standards.

Dear Maarten Vissers,
Thank you for your feedback.
The post owner will reply you ASAP, thank you for your waiting.

Thanks for your reply, there may be some misunderstanding. I agree with your comments about ODUflex, but I still think ODUflex is rigid and hard pipe currently. Although ODUflex bandwidth can be set and only can be set as 1 x 1.25G, 2 x 1.25G, ...,N x 1.25G, but once set up bandwidth of ODUflex pipe, then it is fixed and can not be auto-adjusted with traffic changes. When the product supports G.7044 protocol, perhaps we can use the real flexible ODUflex in future.

Of course, ODUflex can carry any customer traffic, but currently if the actual traffic flow is less than the set bandwidth of ODUflex pipe, will waste some bandwidth.

Nice post..Simplified distinction in OTN & PKT
