This sounds like something that needs to be supported by network equipment (access gateway, router, etc.) that has been designed to do such rate limiting. The sites you list are likely to use content distribution networks where there are many IP addresses that serve the content based on user's location. In other words, making a list of which IP addresses need to rate limited would need specialised software built for this purpose. However, it might that e.g. all Facebook servers are within on IP address block. If so, then rate limiting can be possible with more general purpose network equipment too. When using Radiator, Radiator can return specific attributes that assign different rate limit groups for users A, B and C. When the user logs in, group identifier is fetched from e.g. SQL during the authentication process. The identifier is then returned with RADIUS Access-Accept. Lets say identifier '1and3' is what user A should get. The rate limits in this case would be prepared in advance. When access is accepted and there is a rate limit identifier '1and3', this would rate limit A's traffic as you had in your example. RADIUS protocol can also be used to return rate limiting information directly with each Access-Accept when using appropriate RADIUS attributes. These attributes could list IP address blocks with their respective rate limit information. Please note that what I wrote was to give some ideas instead of going into too much detail. More detailed information requires knowing more about your setup and what equipment you have or plan to use. In summary: what you describes sounds possible. When you evaluate equipment that support the functionality you require, look for what is supported via RADIUS. If the equipment supports setting rate limit information via RADIUS, there is quite good possibility Radiator can be used as the RADIUS server. Thanks!
