Question
In Huawei's WAN solution, for scenarios where " intermittent packet loss occurs in the WAN link," which of the following technologies can "ensure the reliability of data transmission through a retransmission mechanism"?
Options
- AIgnoring packet loss and not performing any retransmission processing leads to data loss.
- BTCP-based retransmission mechanism (automatic retransmission of lost data packets)
- CReduce the transmission rate to forcibly reduce the probability of packet loss.
- DRelies solely on link-layer retransmissions, without handling network-layer packet loss.
