Transport networks have a variety of mechanisms to facilitate separation of data plane and control plane, distributed signaling for path setup and protection, and centralized path computation and traffic engineering. These represent key technologies for enabling flexible and dynamic networking and efficient control and protection of resources. As transport networks evolve, there is a need to provide network abstraction that has emerged as key requirement for operators to facilitate virtual network operation: creation of a virtualized environment to view and control multi-subnet multi-technology transport networks into a single virtualized network. Network abstraction of transport networks is also necessary for operators that consolidate their network services into multi-tenant virtual transport networks that share the common core transport network resources. This will accelerate rapid service deployment of new services, including more dynamic and elastic services, and improve overall network operations and scaling of existing services.
A need for virtual network operation based on the abstraction of underlying technology and vendor domains would be used for a variety of key use cases, including:


·     Network operators that need to build virtual network operations (VNO) infrastructure via standards-based API that facilitates automation and operation of connectivity services across their multiple domain networks as well as multi-tenant virtual service networks that use their common core transport network resources.


·     Data Center operators that need to lease facility from a number of physical network infrastructure providers to offer their global data center applications and services. As they face multi-domain and diverse transport technology, interoperability based on standard-based abstraction will enable dynamic and flexible applications and services. 

This BoF is a non-WG forming BoF. This BoF will be organized in such a way that gives operators an opportunity to express their current operational practices, highlighting operational pain points, network virtualization requirements and objectives, short-term goals, and longer-term aspirations.

Next Steps
A non-WG forming BoF session will be held in the 90th IETF meeting (Toronto July 25-30, 2014). Please see BoF Planning Information sub-section for details.
