System for monitoring network communication data packets

Abstract

The invention belongs to a system for monitoring network communication data packets in the field of information network systems. The system consists of an IP data packet analysis unit and a network address translation unit, and is characterized in that the system also comprises a unit for transmitting network address translation information and an association processing unit for network address translation information; the system has the following connection relation that: the network address translation unit is connected with an IP private network, the unit for transmitting network address translation information and the IP data packet analysis unit respectively; the unit for transmitting network address translation information is connected with the association processing unit for network address translation information; the association processing unit for network address translation information is connected with the IP data packet analysis unit; and the IP data packet analysis unit is connected with an IP public network. The system can realize centralized monitoring for IP data packets sent or received by communication equipment in the private network so as to ensure that one IP data packet monitoring device can simultaneously monitor the IP data packets generated by a plurality of private networks, thereby greatly reducing the cost for constructing IP data packet monitoring systems.

Description

Technical field: [0001] The invention belongs to the field of information network systems, in particular to a system for monitoring network communication data packets. Background technique: [0002] In the process of network communication, each communication device needs an IP (Internet Protocol, Internet Protocol) address. According to the IP address allocation scheme, IP addresses can be divided into public network IP addresses and private network IP addresses. Generally, a communication device needs to have a valid public IP address to access the Internet. However, since the number of public IP addresses is not sufficient, it cannot be guaranteed that each communication device can have a public IP address. In order to enable normal communication between devices in the private network and devices in the public network, a network address translation (NAT, Network Address Translation) device is required to convert the IP address in the private network to the IP address in t...
