---------------------------------------------------------------------
Solution:
---------------------------------------------------------------------

The application server APS needs to execute the following four steps:

	1. APS allocates UDP port i in sh
	2. APS allocates any UDP socket ss in sh
	3. APS binds UDP socket ss to UDP port i in sh
	4. APS adds entry (port i, socket ss) to UDP socket table in sh
