DBNS is a network security system composed of latest opensource big data components. Within the architecture building and efficiency optimization, the DBNS system can afford various methods to analysis 1GBPS network flow within a single node server, and up to 10GBPS network flow within a three-node server cluster. In the github, we show the source code of the single-node mode and wish you to provide your advice for our project.
DBNS system is developed by Network Computing Center of Shanghai Jiaotong University. You can contact luoshengjie@sjtu.edu.cn for more information.
DBNS system is made of four layers.
- Information Layer: Collect the package from the NIC and resolver the package by PCAP components
- Platform Layer: A online stream computing platform to distribute the package data into different database. Some online statitic process is finished here to cutoff the overload in following steps.
- Analysis Layer: Online analysis, which provides report each minute, and offline analysis, which provides report each hour are main part of this layer. DBNS takes a duty of network monitor and problem detection.
- Displayer Layer: Well-designed web UI for users to employ the analysis result.
