Early-warning decision method, node and sub-system

Network traffic processing includes: determining whether one or more packets of network traffic associated with a first public network address have been dropped, the first public network address being associated with a target host; in response to the determination that the one or more packets associated with the first public network address have been dropped, assigning a second public network address to the network traffic and generating a forwarding path corresponding to the second public network address, wherein the second public network address is configured to receive the network traffic, and wherein the forwarding path is configured to forward the network traffic received at the second public network address to the target host; and notifying a filtering device to transmit the network traffic to the second public network address and cause the network traffic to be forwarded to the target host according to the forwarding path.
