Instead, our Dapper system analyzes TCP performance in real time near the end-hosts (e.g., at the hypervisor, NIC, or top-of-rack switch). ...
To reduce the data-plane state requirements, we perform lightweight detection for all connections, followed by heavier-weight diagnosis just for the troubled connections. ...
This paper presents Dapper, a Data-Plane Performance diagnosis tool that infers TCP bottlenecks by analyzing packets in real time at the network edge, as shown in Figure 2 . ...
