IDTCP: An effective approach to mitigating the TCP incast

WebIncast congestion typically happens in a data center network when multiple servers, all connected to the same switch, are sending data simultaneously to a common destination, such that the switch buffer overflows, resulting in packet loss. This paper proposes a method for incast congestion control for TCP (ICTCP), which tries to avoid this ... WebIn cloud data center networks (DCN), TCP incast usually happens when multiple senders simultaneously communicate with a single receiver. However, when TCP incast happens, DCN may suffer from both throughput collapse for TCP burst flows and temporary starvation for TCP background flows. significance of kashgar
