Map descending and ascending sorting on vf page when user clicks on command link --> urgent help me

Hi is anyone got the solution to this sorting problem.

I am unable to do descending order sorting.
My requirement is I have map Of <Id,Name>  when user click on the link the map values need to sort either ascending or descending order

Example If the Map values contain
Map.put(id1,Name1);  
Map.put(id3,Name3);  
Map.put(id2,Name2);  
Map.put(id5,Name5);  
Map.put(id6,Name6);  
Map.put(id4,Name4);  

Result for ascending 
Map.put(id1,Name1);  
Map.put(id2,Name2);  
Map.put(id3,Name3);  
Map.put(id4,Name4);  
Map.put(id5,Name5);  
Map.put(id6,Name6); 

Result for desendoing\

Map.put(id6,Name6);  
Map.put(id5,Name5);  
Map.put(id4,Name4);  
Map.put(id3,Name3);  
Map.put(id2,Name2);  
Map.put(id1,Name1); 

I did use different methods to solve this but nothing is working me out. Please, anyone, help me out I need to solve this issue.
One ve page I need to display these values.

Thank you
Aruna
