Multi-layer, integrated DP & CP Solution Efficient, integrated multi-layer solution : Multi-layer, integrated DP & CP Solution Efficient, integrated multi-layer solution UNI 2.0 Ethernet: First multi-/ dual-layer, integrated data and control plane solution within a network domain
It enables:
Automatic, dual-layer connection provisioning
Efficient inter-layer interworking
Concept could be extended to any other dual/multi-layer approach
Multi-layer, integrated DP & CP Solution Mandates cooperation among SDOs and forums : Multi-layer, integrated DP & CP Solution Mandates cooperation among SDOs and forums Data and control plane functions integration mandates integration of function from different SDOs / forums and therefore their close cooperation, e.g. for UNI2.0 Ethernet:
OIF UNI2.0 Ethernet specification
ITU-T set of ASON Rec.
ITU-T set of NG-SDH Rec.
ITU-T set of Ethernet service Rec.
IETF signaling standards
IEEE set of Ethernet standards
MEF Ethernet service specifications

Separation of TN and client view Independent technology platforms used by TN and client : Separation of TN and client view Independent technology platforms used by TN and client Using UNI2.0Ethernet the client and transport network (TN) view is separated not only on the control plane level, but even on the technology level (data plane), enabling
Client Ethernet view and functions
For the TN an independent selection of the technology platform as appropriate, e.g.
Native Ethernet
SDH/SONET
OTN
UNI-C 2.0 Ethernet – Client Interface As simple as possible : UNI-C 2.0 Ethernet – Client Interface As simple as possible Client could stay with the preferred Ethernet functions, capabilities and know how, all the needed adaptation and multi-domain issues are accomplished by the TN: UNI-N and E-NNI interfaces.
Nevertheless the UNI-C control plane functions have to be implemented by the clients!
How to insure broad implementation/deployment of UNI-C 2.0 Ethernet interfaces in a client environment not familiar with control plane topics??
Advertisement & education, by making the implementation easy to understand (cookbook)
Making UNI-C 2.0 Ethernet proxy commercially available
Follow-up Activities : Follow-up Activities The OIF interoperability tests and demonstration area a main, but intermediate achievement on the roadmap to deployment.
They build the bases or starting point for various ASON/GMPLS field trials, e.g.
Japan, NiCT / JGN II (www.jgn.nict.go.jp/e/02-about/02-3/index.html)
Germany, VIOLA (www.viola-testbed.de)
Europe, MUPBED (www.ist-mupbed.org)
Europe, NOBEL (www.ist-nobel.org)
