Example Embodiment
[0035] Taking an anti-virus application security gateway as an example, a UDP data packet transmission method of the present invention will be described in detail with reference to the accompanying drawings.
[0036] Fig. 1 is a system structure diagram of this embodiment.
[0037] The kernel data structure of the data packet contains a non-local data packet identification field bsepsocket. The local network protocol stack of the application gateway distinguishes non-local data packets according to whether this field is set to 1. (that is, the destination IP address and source IP address are not local IP Address data packets) and local data packets.
[0038] The kernel data structure of the data packet also contains a local listening port field sepsocket_listen_port of the socket to which the data packet belongs. By setting this field, the data packet is allocated to a datagram socket created by the business program for processing and different data is realized. Report load balanci...
