Ethernet data acquisition network card and Ethernet data acquisition method

Abstract

The invention discloses an Ethernet data collection card, at least including: an Ethernet data exchange module which is connected with multi-channel Ethernet link requiring monitoring and is used for the aggregation of the multi-channel Ethernet link data requiring monitoring; a pre-processor module for connecting with the Ethernet data exchange module, which is used for pre-processing the multi-channel link data aggregated by the Ethernet data exchange modules and for sending the multi-channel Ethernet link data after being pre-processed to the main processor of a monitoring device connected with the pre-processor module. The invention also provides a method for collecting Ethernet data. In this way, the invention collects the multi-channel Ethernet link data requiring monitoring on intelligent ethernet cards; and the invention supports the multiple Ethernet link, wherein the number of net openings supported is determined by the exchange specification of an Ethernet switch chip; furthermore, the invention is not limited to PCI bus on the connection between the pre-processor module and the main processor of the monitoring device.

Description

technical field [0001] The invention relates to the field of communication network monitoring, in particular to an Ethernet data collection network card and a method for realizing Ethernet data collection by using the Ethernet data collection network card. Background technique [0002] Today, with the increasing popularity of communication networks, in order to monitor the operation quality of the communication network in real time, discover various potential problems in the operation of the communication network in time, and quickly and accurately locate the fault point, all major telecom operators have built their own monitoring networks. [0003] For a typical monitoring network, it must have the ability to extract data from the live network. In an Ethernet-based communication network, there are three ways to extract data: the first is to use the method of mirroring the Ethernet switch to aggregate the Ethernet data that needs to be monitored to the designated network por...

Problems solved by technology

Its disadvantages are: First, the number of Ethernet links connected by this type of smart network card is very limited. The above-mentioned smart network card can only be connected to two Ethernet channels. Second, in the above two patents, it is clearly proposed that the main processor of the smart network card and the monitoring device is based on the PCI bus, so these two kinds of smart network cards can only be inserted in the PCI slot, With the development of technology, the application range of this backplane interconnection method has certain limitations.
