TCP will not cause IP sharding, while UDP and ICMP will cause IP sharding. Why does TCP not cause IP sharding? The reason is that TCP itself supports segmentation: when TCP needs to transmit data with a length greater than the MSS (Maxitum Segment Size), it first segments the data. Normally, the MSS is smaller than the MTU. Therefore, TCP generally does not cause
