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 [email protected] 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.

• version 0.1: released in 01.15.

  Content: A single-node demo within the install script. The network monitor function is focused in this stage and problenm detection would be simple temporarily.  

• version 0.2: released in 02.30

  Content: A multi-node version would be released.

• version 1.0: released in 03.30

  Content: The official version. The network would include all function in these documents.

• version 2.0: released in 04.30

  Content: The Graphic-Computing version. Graphic Computing components would be part of the DBNS system.
