WebPacket loss is usually caused by network congestion where packets are sent faster than the receiver or switch can process. Conventional ethernet silently drops packets and expects retransmission if data is sent too fast. It is this packet drop that causes huge hits to latency and throughput. Exadata avoids packet drops by using two specific ...
