Abstract

The data packet processing method under multiple programming languages environment is a solution for network security and software development technology, mainly used for solving the development and application problems of a network data packet processing program, and belongs to the field of computer network and software engineering technology. The invention also provides a code implementation ofa filter transplantable to a router. The monitoring and processing of network data packet have always been an important and key technology in network security field. The processing scheme of the invention is provided for quickly and effectively processing network data packet, and protecting our server and host from network attack. Therefore, multiple languages are employed for implementation, optimal filtering factors are added, so that the filtering efficiency is maximally improved. The code implementation of the filter can be used on multiple servers and personal hosts under complex networkenvironment, used as a basis of related network data packet processing software.

Description

technical field

[0001] The invention is a solution to network security and software development technology, which is mainly used to solve the development and application problems of network data packet processing programs, and belongs to the cross field of computer network and software engineering technology. Background technique

[0002] Firewalls are used to protect computer networks from harassment by unauthorized personnel and intrusion by hackers. It forms a security protection barrier between the internal network (private network) and the external network, preventing illegal users from accessing resources on the internal network and illegally transmitting internal information to the outside. A firewall can be a very simple filter or a well-configured gateway, but the principle is to monitor and filter all information between the internal network and the external network.

[0003] Packet filtering is one of the most basic functions of a firewall, and many routers ofte...
