Figure 6 – Allocation

In order for a LINP to become operable, virtual link resources and virtual node resources that are allocated
to the LINP have to be interconnected logically. The interconnection is completed by binding the virtual link
resources and the virtual node resources together, as depicted in Figure 7.

8 Physical node architecture
One of the most significant challenges in the node architecture that instantiate LINPs out of physical
resources is a scalable design in terms of the number of LINPs to be instantiated.
A physical node resource has a collection of physical resources, i.e., computing, storage and transport
resources. The evolutions of technologies for creating these resources tend to have different speed. For
example, transport technologies often make progress with a different speed compared to that of
computation and storage. Also, computing and storage resources are often managed together in
programming data processing functionalities.

To construct a scalable node design, a physical node resource is highly recommended to be divided into two
hardware components in terms of management of resources: a programmer that manages computing and
