Document Summary
Should not be faster than the sender"s share . Should not be faster than the network can process . Cc & bandwidth allocation are separate ideas, but frequently combined. It depends! (in what way are you trying to share??) We don"t want to waste effort in the network! Should not send more than we can handle! (more traffic than can get through the network) The smallest link gets the most it can do! Some flows are going to want more capacity, but sometimes we have to say no. State where you have way more demand than what the network can handle over the long term. Buffers can absorb bursts, but cannot handle long term. Throughput is x=y initially (packets going in and out) Once you start flooding the queues, then your throughput will plateau to the max physically capacity of the network. Once they can"t get their packets in, senders will slow down (throughput decreases)
