4 # Hierarchical queueing for a university.
5 # Three faculties; engineering, law and art are defined.
6 # Departments under the engineering faculty are defined as child queues.
7 # The total bandwidth for engineering faculty is shared between three
8 # departments. CS department gets the half of the bandwidth, EE and IE
9 # departments get the thirty percent and twenty percent of bandwidth
10 # respectively. These sibling departments can use more than their linkshare
11 # whenever there is no backlogged sibling queue but when a queue gets
12 # backlogged, it is guaranteed that the queue gets its linkshare.
