1 Core network aspects

The requirements for the virtual resource management are as follows:

– The virtual resource management is required to provide LINP identification means, such as LINP
identifier (LINP ID), to differentiate LINPs.
– The virtual resource management is recommended to provide capability to collaborate with the
physical resource management so that virtual resources can be allocated to an LINP effectively and
efficiently.
– The virtual resource management is recommended to abstract an aggregated set of physical and
virtual resources into a virtual resource in order to enable simplified control of virtual resources by
LINP management.
– The virtual resource management is recommended to provide capabilities for monitoring or control
of virtual resources to LINP management.
– The virtual resource management is recommended to change mapping between physical resources
and virtual resources dynamically in the case of events like failures or performance degradations
– The virtual resource management is recommended to change mapping between physical resources
and virtual resources according to requests for reconfiguration of LINPs from one or more LINP
operators.
– The virtual resource management is recommended to allow LINP operators to configure LINPs
quickly without imposing complexities of physical network operation including management of
network addresses and domain names.
– The virtual resource management is recommended to allow LINP operators to reconfigure virtual
resources to optimize performance and/or efficiency of LINPs through a simplified control interface.
In this reconfiguration process, service interruption should be minimized to maintain quality of
services on the LINPs.
– The virtual resource management is recommended to gather physical and virtual resource
information, such as bandwidth consumption and CPU utilization.

7.3 LINP management

LINP management enables LINP operators to apply management policies to an LINP.
The requirements for the LINP management are as follows:
– The LINP management is recommended to reconfigure an LINP by reallocating virtual resources to
the LINP so that the LINP operator can adapt the LINP profile to changes in service properties.
– The LINP management is recommended to terminate an LINP and release all the virtual resources
that are no longer needed.
– The LINP management is recommended to monitor the status of a running LINP, such as traffic
volume, energy consumption and utilization of virtual resources.
– The LINP management is recommended to optimize an LINP so that the LINP can be controlled and
managed efficiently to adapt to environmental changes such as traffic fluctuations and equipment
failures. In this optimization process, service interruption should be minimized to maintain quality
of services on the LINP.

7.4 Service management

Service management enables an LINP operator to support service provisioning without complex interworking
between the LINP operator and the network provider who provisions LINPs to the LINP operator, since the
service can be composed of a large number of software components, that is, combinations of application
programs and virtual resources.
The requirements for the service management are as follows:
– The service management is required to isolate applications or application-specific programs in order
to execute them independently on different LINPs without interfering with each other.
