The method comprises: in response to receiving a preparation signal for restarting a network service process, configuring a packet enqueueing rule for Iptables in a Linux operating system, and caching a pending packet from a kernel space to a user space; and through implementing a packet releasing program in the user space, releasing the pending packet cached in the user space to the kernel space in response to receiving a completion signal of completing restarting the network service process, such that a connection between the pending packet and a new process of the network service is established. An IP packet filtering system caches the pending packet from the kernel space to the user space, based on NFQUEUE or QUEUE.
