Abstract:
Previously transport networks were typically static, lacked
flexibility, and required 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 for meeting
operator's requirement for their virtual network operation.
Virtual network operation refers to the creation of a
virtualized environment allowing operators to view the
abstraction of the underlying multi-admin, multi-vendor, multi-
technology networks and to operate, control and manage these
multiple networks as single virtualized network. Another
dimension of virtual network operation is associated with use of
the common core transport network resource 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, scope of work,
and outlines the core requirements to facilitate virtual network
operation.
