The use cases of mobility in LINPs are as follows:

Figure II.1 shows use cases of user and application mobility in LINPs.

Each LINP may provide different virtual resources. In this example, LINP 1 is created based on low-
powered virtual resources with very limited central processing unit (CPU) power and bandwidth.
LINP 2 is created based on large virtual resources, which can provide large bandwidth and processing
power. In this case, User 1 is currently connected with LINP 1 to use application APP1. When User 1
needs to use application APP 2 which requires high computing power, the LINP manager discovers
LINP 2 for User 1. In addition, if User 1 still needs to use APP1, APP1 can be accessed from LINP 2 or
APP1 can be moved from LINP 1 to LINP 2 for User 1. Therefore, the LINP manager will handle not
only the user mobility but also the mobility of application, which is used by the user in the previous
LINP.
Figure II.2 shows use cases of system image and resource mobility.
