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
