The CCNx reference implementation uses XML and ccnb to describe and encode the Interest and Data packet, but currently most security communication uses CMS based on ASN.1 and BER to characterize the protocol packet. Therefore, in order to be compatible with these existing crypto technology and products, we propose to reformat the Interest and Data packet with CMS. In addition, BER encoding causes...
Classifying encrypted traffic is critical to effective network analysis and management. While traditional payload- based methods are powerless to deal with encrypted traffic, machine learning methods have been proposed to address this issue. However, these methods often bring heavy overhead into the system. In this paper, we propose a hybrid method that combines signature-based methods and statistical...
Thunder (also called Xunlei) is the most popular P2P file sharing application in China and probably the most popular P2P software in term of traffic volume and number of users. Precisely identifying Thunder traffic can help network administrators to efficiently manage their networks. Traditional methods of identifying P2P traffic such as port-based or content-based approaches are ineffective to Thunder...
Data De-duplication has become a commodity component in data-intensive storage systems. But compared with other traditional storage paradigms, de-duplication system achieves elimination of data duplications or redundancies at the cost of bringing several additional layers or function components into the I/O path, and these additional components are either CPU-intensive or I/O intensive, largely hindering...
