Embodiment Construction

[0015] The present invention will be described in detail below with reference to the drawings and embodiments.

[0016] This embodiment provides an Ethernet data interception device based on non-injection two-way communication packet capturing technology, which can be used in any occasion where there is a requirement for two-way interference-free interception of Ethernet communication between network nodes.

[0017] Such as figure 1 As shown, the network listening device includes: a listening interface, a listening network card, a universal network card, an input and output interface, and a lithium ion battery that supplies power to the entire listening device. The listening interface is two RJ45 interfaces; on the physical line, the two network nodes on the communication link ( figure 1 The network node 1 and network node 2 in the network are respectively connected to the network listening device through two RJ45 interfaces, and the two RJ45 interfaces are directly connected insi...

Abstract

The invention discloses a non-injection type network interception apparatus which enables interception, processing and forwarding of bidirectional data on a communication link without any effect on an original data connection route; the non-injection type network interception apparatus can be applied to any occasion having needs for bidirectional interference-free interception of Ethernet communication among network nodes. Two pairs of data transmission lines of the original data route are subjected to parallel shunting operation via the interception apparatus, then the data transmission lines are connected into an interception network interface card; bidirectional data on a network communication link is simultaneously received via the interception network interface card; a network card drive of an embedded operating system of the interception apparatus is also employed; bidirectional passive non-coupling interception can be performed on a data flow of the communication link. When data is transmitted bi-directionally between two network nodes, the interception apparatus can monitor communication data packets on a transmission line. The interception apparatus provides multiple kinds of input interfaces and output interfaces, original data intercepted can be subjected to data processing operation via a user application program and a high-performance CPU, and processing results can be output via the output interfaces.

Description

Technical field [0001] The invention relates to a listening device, in particular to an Ethernet data listening device based on non-injection two-way communication packet capture technology, which belongs to the field of network communication. Background technique [0002] Ethernet is an earlier communication network that has been widely used. When network communication fails, or when testing and monitoring Ethernet nodes, it is often necessary to monitor the communication data between Ethernet nodes. There are mainly two existing network listening methods. One is with the help of mature technology hubs (HUB) or switches. The hub will forward all received data to each of its connected ports. When the host sends data based on the MAC address, although the information contains the address of the destination host, other nodes will also receive these communication packets, but other nodes will ignore them under normal conditions; for the switch, although the port to Port data trans...
