Description

Following an incident with a slow database replication between CERN's data centers, we discovered that even a very low rate packet loss in the network (order of 0.001%) can induce significant penalties to long distance single stream TCP transfers. We explore the behaviour of multiple TCP congestion control algorithms in a controlled loss and delay environment in order to understand what is the achievable throughput of TCP data transfers between CERN’s remote data centres.
