Please include OTN & MS-OTN services seperately

The second phase will compare OTN and MS-OTN.

That is the content of issue 02: What MS-OTN Means to Me (2): OTN vs PKT

http://support.huawei.com/gsbbs/bbs/32707.html

One of the objectives I had when I developed the MS-OTN concept was the reduction of the layer network stack of the L2/L1/L0 network, and with that reduce the OPEX.

Each transport technology has in general a service layer, one or more tunnel layers and a section layer and OTN and Ethernet have furthermore physical media layers. By combining L2 with L1/L0 in the MS-OTN it is possible to remove the Ethernet and MPLS-TP section layers; their role is now performed by the L1 service layer.  Furthermore due to the continuous growing L2 tunnel bandwidth, the function of these L2 tunnel layers/connections can be provided by L1 service layer/connections (specifically by the ODUflex connections); this will become economical when the L2 tunnel bandwidth is ~300 Mbit/s or more. Doing so implies that MPLS-TP tunnel layer (referred to as Transport-LSP layer) and the Ethernet tunnel layer (referred to as the Backbone Ethernet Connection layer) can be bypassed in (and in future removed from) the layer network stack in an MS-OTN network. Result will be a MS-OTN network with three parallel service layers (OTN ODUk, Ethernet Service-EC and MPLS-TP PW/Service-LSP) that are supported by the OTN ODUk tunnel layer.

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

for most scenarios, I agree with you, especially to big commany, such as DT/BT/Telefonica etc. But, to lease line application, L2 is need for customer to got the bandwidth they wanted; and to some mobile backhaul aplplication, MPLS-TP is need for bandwidth sharing. 

MS-OTN reduces CAPEX due to integration of Ethernet layer within itself.

Dear tanjil,
Thank you for your words leaving.
