Re: Transport Cloud and Network Centers mvissers,

Thanks for the comment.

You made some interesting observations about how Transport Cloud / T-Cloud can help simplify network connections through segmentation and abstraction. These are powerful concepts that enable innovation while hiding nnecessary detail.

Re: It's all about Ops Pull_Request,

Thanks for the observation.

I agree that the operations model, its staff and its tools will need to be updated to utilize a cloudified model.

While this is a big change, I am already seeing operators start to move down this path. Changes include getting operations involved early in the technology process, and the flattening of silos to work in a DevOps model.

Transport Cloud and Network Centers Cloudification of the communication services in the optical transport network is a study item for some time and might be realised by means of a Transport Cloud. A T-Cloud allocates a network slice to each user, which consists of a set of slice switch resources that are interconnected by FlexTunnels (FlexT). Slice switch resources are user programmable. FlexT payload structures are also user programmable. FlexTs are supported by OTN ODUflex connections, which can have any bit rate. Central offices that provide such slice switch resources within OTN nodes or connected to such nodes can be viewed as Network Centres within the T-Cloud. Users can program their slice switches with L1, L2, L3, etc based forwarding capabilities and can configure VPNs within each network slice in which user defined flows can be forwarded. The slice switch resources are the equivalent of the server blades in data centres, the optical transport network is the equivalent of the Ethernet data centre network, but provides a world wide connectivity between slice switch resources. Slice switch resources can be associated with 2nd, 3rd and future generation OTN access, metro, core and backbone nodes. Multi-operator/multi-vendor interworking is implicitly supported. T-Cloud goes beyond today's NFV, because network operators as well as other, 3rd party users can program and operate/control the slice switch resources and FlexT payload structures. Slice switch resources are considered to be FPGA or NPU based. With this approach, cloudification of communication services in transport networks will be an evolution, not a revolution. Management and control for network operators will be simplified; network is only responsible for the network slice. The user's management/control will be responsible for the management/control of the specific services within each network slice.

It's all about Ops This is all well and good but the real issue lurking beneath all the shinny new technology is Operations. While the impact to twent year old equipment and architecture is not trivial, the impact to 40 year old operational model will be life threatening if it's not addressed up front. Some operators don't have enoughfinancial runway to withstand an extended learning curve as they figure out how to squeez maximum cost and efficency out of thier new cloud.
