Think of SDR as the ability to have multiple virtual routers on the same physical hardware. So it's not per user or anything like that, it is simply you can have multiple logical routers and you can use these routers as you would a single physical router. It's like using contexts on the ASA or FWSM firewalls if you are familiar with them.
Each logical router has it's own configuration, it's own routing tables, runs it's own routing protocols and these are totally independant of each other. However the logical routers share the physical switch fabric and hardware of the physical chassis. You basically assign certain parts of the hardware to a logical routers.
So a practical application would be you could be servicing multiple customers and each customer could be allocated a logical router on the same physical chassis. This allows you to route that customers traffic totally independantly of the other logical routers and there is no danger of routes getting mixed up. It also has the advantage that if you make a mistake in one logical routers in terms of configuration it will not have an affect on any of the customers using different logical routers on the same chassis.
