Problems solved by technology

[0003] Domestic invention patent 200810019283.9 discloses a multilingual network data packet efficient filtering method. The invention defines and filters data packets through a pre-set rule list, and screens out the required data packets for transmission, but the obtained data packets are still It needs to be sent one by one, and it cannot be transmitted at one time for a large number of data packets, which makes the transmission efficiency lower

Embodiment example

[0038] If in the process of analyzing a network protocol, we only need to analyze the packets of the TCP protocol. The above-mentioned technical solution can be realized according to the following implementation examples:

[0039] Step 1: Data Collection

[0040] The Ethernet network data packet collection device can capture the network data packets flowing through the Ethernet switch by connecting to the mirror port provided by the Ethernet switch. The Ethernet network data packet acquisition device can also capture the network data packets flowing through the Ethernet switch through the connection mode of the Ethernet electrical splitter or optical splitter. These Ethernet electrical splitters or optical splitters are connected across cables or optical cables of Ethernet switches and other network devices. Through the connection between these splitters and the Ethernet network data packet collection equipment, the Ethernet data packets flowing through these circuits or opt...

Abstract

The invention relates to the technical field of data frame definition and usage of a network monitoring packet, in particular to a method and an application of a compound network monitoring packet. A TAP branching unit is serially connected between a server and an IP (Internet Protocol) switcher or router connected to the server, wherein a branch of the TAP branching unit is connected to a data collecting device; the data collecting device is connected to a follow-up processor; the TAP branching unit is used for copying various packets sent by the server at real time and sending the packets to the data collecting device; the packets collected by the data collecting device are original packets; the data collecting device is used for defining the data frames of the original packets; an operation system is used for storing the original packets; and the collected original packets on the data collecting device are combined and merged, thereby forming the compound network monitoring packet; and the compound network monitoring packet is sent to the follow-up processor and is subjected to the follow-up processing. The method and the application of the compound network monitoring packet provided by the invention are used for obviously reducing the load capacities of the data collecting device and the follow-up processor and reducing the energy consumption of the device.

Description

[technical field] [0001] The invention relates to the technical field of network communication monitoring, in particular to a method for defining and using a data structure or frame format (Data Frame) of a monitoring data packet, that is, a method and application of a composite network monitoring data packet. [Background technique] [0002] Today, IP networks are widely used. There are various network storms, viruses or network attacks, and network frauds that affect the normal use of the network, which often cause network paralysis. At this time, network maintenance and management personnel need to pass through The data packets on the network are captured and analyzed based on the captured data packets to analyze the behavior of various network users on the Internet. Usually, the captured data packets are filtered, the unconcerned data packets are discarded, and the data packets that need to be analyzed are transmitted to other computers or special equipment for processing...
