Problems solved by technology

However, because the packets that need to be forwarded to the external network pass through the address translation module twice, it not only wastes the time for forwarding packets, but also reduces the efficiency of the IP sharer

Embodiment Construction

[0014] figure 1 Shown is a block diagram of the network communication device 20 in an embodiment of the present invention. In this embodiment, the network communication device 20 is communicatively connected to multiple user terminal devices 10 and the network 30 , and is used to forward multiple packets sent by the user terminal devices 10 to the user terminal devices 10 or the network 30 . In this embodiment, the multiple packets sent by the user terminal device 10 include internal packets that the user terminal device 10 communicates with each other, self-packets that the user terminal device 10 sends to the network communication device 20, and packets that are sent to the network 30 or A forwarded packet is received from the network 30 . In this embodiment, the self-packet is a packet for parameter setting of the network communication device 20 by the user terminal device 10 . In this embodiment, the network communication device 20 is an IP address sharer with a Network ...

Abstract

The invention discloses a network communication device communicating with the network. The device comprises a transceiver module, an address translation module, buffer control module and a network communication protocol routing module, wherein, the transceiver module is used for receiving and sending packets, the address translation module is used for translating the addresses of the packets sentby the transceiver module and identifies the packets of which the addresses having been translated by using identifying values, the buffer control module is used for recording the identifying values of the packets, the network communication protocol routing module is used for routing the packets. When the packets are sent by the network communication protocol routing module to the address translation module, it is judged whether the address translation is performed by enquiring the identifying values; if the address translation is performed, the packets are sent to the network directly. The invention also provides a packet routing method. By using the network communication device and the packet routing method, packets does not need to enter the address translation module for two time whenforwarded, and the packets forwarding time is saved and the packets forwarding efficiency is improved.

Description

technical field [0001] The invention relates to a network communication device, in particular to a network communication device and a routing method for a network communication device and its packet after address conversion. Background technique [0002] When the scale of an enterprise continues to expand, the internal network of the enterprise also expands accordingly. Due to the increase of its business, the communication between the internal network and the external network of the enterprise increases. [0003] Usually, when an enterprise registers to go online, the practical network communication protocol (Internet protocol, referred to as IP) address used by the company is limited. The communication connection between the network and the external network. Set multiple virtual IP addresses inside the enterprise network, and convert the virtual IP addresses into practical IP addresses through the IP sharer, so that the internal network can communicate with the external n...
