CloudEngine16800: Industry's First Data Center Switch Built for theAI Era

5. AI Chip：
Based switch’s built-in smart chip,
zero network packet loss is
realized for the first time, and the
full potential of AI-era computing
power is unleashed.
iLossless Formula：
Huawei's original intelligent
lossless algorithm (iLossLess),
means that an Ethernet network
can now experience zero packet
loss.
