Abstract
A network application program product and a method for processing an application layer protocol are provided. The network application program product includes a network application program executed in a user mode and a packet filtering module executed in a kernel mode. The network application program transmits connection information, associated with network connection to the network application program, to the packet filtering module. The packet filtering module captures a to-be-processed packet on the network connection according to the connection information; analyzes the to-be-processed packet into at least one protocol data unit; compares the protocol data unit with preset code content; and transmits the protocol data unit to the network application program or the data access module according to the comparison result for later processing.
