ACTN refers to the set of virtual network operations needed to
orchestrate, control and manage large-scale multi-domain TE networks
so as to facilitate network programmability, automation, efficient
resource sharing, and end-to-end virtual service aware connectivity
and network function virtualization services.
These operations are summarized as follows:
- Abstraction and coordination of underlying network resources
to higher-layer applications and customers, independent of how
these resources are managed or controlled, so that these
higher-layer entities can dynamically control virtual
networks. Where control includes creating, modifying,
monitoring, and deleting virtual networks.
- Multi-domain and multi-tenant virtual network operations via
hierarchical abstraction of TE domains that facilitates
multi-administration, multi-vendor, and multi-technology
networks as a single virtualized network. This is achieved by
presenting the network domain as an abstracted topology to the
customers via open and programmable interfaces. Which allows
for the recursion of controllers in a customer-provider
- Orchestration of end-to-end virtual network services and
applications via allocation of network resources to meet
specific service, application and customer requirements.
- Adaptation of customer requests (made on virtual resources) to
the physical network resources performing the necessary
mapping, translation, isolation and, policy that allows
conveying, managing and enforcing customer policies with
respect to the services by the network to said customer.
- Provision of a computation scheme and virtual control
capability via a data model to customers who request virtual
network services. Note that these customers could, themselves,
be service providers.
ACTN solutions builds on, and extend, existing TE constructs and
TE mechanisms wherever possible and appropriate.
This epic is set up to implement the following MDSC functions in the "H" release:
- TE Extensions for Device Subsystem
- TE Extensions for Link Subsystem
- TE Topology Subsystem
- Topology Database
- ONOS GUI to show TE topology hierarchy
