Abstract:
Transport networks that provide connectivity and bandwidth for
customer services have typically been static, lacking
flexibility, and requiring long planning times when deploying new
services. Network Providers and Service Providers have embraced
technologies that allow separation of data plane and control plane,
distributed signaling for path setup and protection, and centralized
path computation for service planning and traffic engineering.
Although these technologies provide significant benefits, they do
not meet the growing need for network programmability, automation,
resource sharing, and service elasticity necessary to meet
operators' requirements for virtual network operation.
Virtual network operation refers to the creation of a
virtualized environment allowing operators to view the
abstraction of the underlying multi-administration, multi-
vendor, multi-technology networks and to operate, control, and
manage these multiple networks as if a single virtualized network.
Another dimension of virtual network operation is the use of
common core transport network resources by multi-tenant service
networks as a way of providing a virtualized infrastructure to
flexibly offer new services and applications.
The work effort investigating this problem space is known as
Abstraction and Control of Transport Networks (ACTN). This
document provides an ACTN problem description, a scope of work,
and outlines the core objectives and requirements to facilitate
virtual network operation.
