I am using Drupal 7 to create a website. In my website, i need to use ad rotator, which have this requirements:

- Allow administrator to manage ads for each page
- Each page may contain different ads
- Administrator may upload more than one ads for each page
- When the user load page, there is only 1 ads will be shown to user and the ads that shown to user may randomly or sequentially load.

For example:

- I have 2 pages, which are page A and B. Then for page A I have 2 ads, which are ads X & Y, and for page B I have 3 ads, which ads ads U, V, & W. When the user load page A, only 1 from 2 ads shown. The ads may randomly or sequentially loaded.
- Let's say, when the first time user load the page, ads Y shown to user, and second time user load the page, ads X shown to user (if ads randomly loaded). Or if the ads sequentially loaded, when the user load page A, then ads X will be shown, after that ads Y, then ads A again, and so on.

My question is:

- Is there any suggestion, which plugin should I use to fulfill my requirements?

Thanks in advance.
