12 LINP operator functions

LINP operator functions operate services on LINPs, in collaboration with virtual resource management
functions and LINP management functions.
To enable or disable service on a LINP, the functions send a request of service activation or of service
deactivation to LINP management functions, respectively.
While operating services, LINP operator functions can also monitor the status of virtual resources by
accessing virtual resource monitoring and fault management function.

13 Service deployment functions
Service deployment functions, implemented either by a network operator or by a service developer, manage,
control, and operate services on LINPs, in collaboration with LINP management functions and service
developer functions. When the functions are implemented by a service developer, the functions use the LMI
reference point to access LINP management functions as shown in Figure 9.

Figure 9 – Functional architecture with service deployment functions supported
by a service developer

Service deployment functions deploy services, which are programmed by service developer functions, on a
LINP. They collect parameters of the LINP by communicating with LINP management functions in order to
deploy the service on the LINP automatically. To enable or disable a service on the LINP, the functions send
a request for service activation or for service deactivation, respectively, to LINP management functions.
Service deployment functions can be used to provide an on-demand service to an end-user, in which case
they discover an appropriate LINP that is highly suitable for the service. In addition, when the attachment
point is changed by the end-user, or when the LINP on which the on-demand service is running does not have
enough resources, the on-demand service is reallocated to another appropriate LINP by service deployment
functions. When the service is reallocated, the set of virtual resources being used to support the service and
