Why Big Data Needs Big Buffer Switches

When many flows pass through a congested switch with limited buffer resources, which packet is dropped and which flow is impacted is a function of whether a packet buffer was available in the precise moment when that packet arrived, and is therefore a function of chance. TCP flows with packets that ...
