Competitive Management of Non-preemptive Queues with Multiple Values

We consider the online problem of active queue management. In our model, the input is a sequence of packets with values v ∈ [1,α] that arrive to a queue that can hold up to B packets. Specifically, we consider a FIFO non-preemptive queue, where any packet that is accepted into the queue must be sent, and packets are sent by the order of arrival. The benefit of a scheduling policy, on a given input, is the sum of values of the scheduled packets. Our aim is to find an online policy that maximizes its benefit compared to the optimal offline solution.
