Abstract

The invention is applicable to the field of data communication, and provides a method for realizing data transmission based on a gatekeeper by aiming at the problems existing in the prior art. The method is used for calculating an HASH ID value by aiming at the conditions that IP messages passing through the gatekeeper are effective, and IP messages passing through the gatekeeper have source IP addresses and target IP addresses. Isolation rule matching of the IP messages is carried out through the HASH ID value, and when the IP messages pass through the gatekeeper, a host at one end of the gatekeeper needs to transmit four or more layers of data to a host module at the other end of the gatekeeper, and the host module at the other end of the gatekeeper reconstructs the received data into IP messages and sends out the IP messages.

Description

technical field [0001] The invention is applicable to the field of data communication, and provides a method for realizing data transmission based on a gatekeeper. Background technique [0002] The gatekeeper is a network security device composed of software and hardware with various control functions. It realizes high-speed and safe data exchange between internal and external networks through mechanisms such as dedicated switching channels and high-speed hardware communication cards. Gatekeepers are generally deployed in networks that require high-intensity security protection for user networks and require information exchange with other untrusted networks. [0003] During the working process, the gatekeeper needs to process a large number of network data packets with different characteristics flowing through the device, and its characteristics include network address, protocol, port and application layer data characteristics. Therefore, the gatekeeper needs to identify th...
