Figure 1 – Conceptual architecture of network virtualization

Figure 2 represents the concept of LINP, which consists of multiple coexisting LINPs over network resources
supporting network virtualization. Each LINP is provided based on user requirements. The requirements are
delivered to the VRM which coordinates the allocation of LINPs so that appropriate LINP is provided to users.
The VRM handles the requirements based on its administration policy. Each LINP is controlled and managed
by an LINP manager. The VRM which is controlling all virtual resources creates an LINP manager and allocates
appropriate authorities to control each LINP. An LINP generated by using network virtualization has various
characteristics, such as partitioning, isolation, abstraction, flexibility or elasticity, programmability,
authentication, authorization, and accounting [b-Vermesan] [b-Nakao2]. The detailed description of the LINP
characteristics is provided in Appendix I.
