Multiple SDN applications can make several harmful interferences unintentionally, although each individual application may be properly developed. This paper proposes a Multiple SDN Applications Interference Detector (MSAID). To bridge the gap between the source code of applications and the actual interferences, we leverage symbolic execution and constraint solving to obtain how the event handler handles...
Nowadays, due to the rapid growing popularity of Internet, the global routing system suffers from great scalability problem. Many solutions are proposed to solve the problem, including FIB aggregation, core/edge separation solutions, et al. The limitation of these existing solutions is that they all make the assumption that all addresses in the Internet must be globally visible and these routing information...
Nowadays, the global routing system suffers from great scalability problem. Core/edge separation solutions are proposed to solve the problem. However, they bring a global mapping system which might also suffer from scalability problem. We come up with an idea to reduce the necessary routing or mapping information, which is to separate content provider networks (containing content providers) from content...
The separation between edge and core addresses has been proposed to address the scalability problem of the Internet routing system. One main challenge is to design an efficient mapping mechanism for the two address spaces. The layer structure is attractive because of its scalability and simple index mechanism, while existing layered mapping system lacks a clear structure study and faces serious deployment...
Geographic-based addressing and routing has been discussed for more than twenty years. In this paper, we clarify the purpose of fitting geographic information into addressing and routing, and further propose a new geographic-based addressing and routing scheme. Our contribution lies in three aspects. First, we classify previous geographic-based addressing and routing proposals into three categories...
Providing flexibility and extensibility, SIP has recently gained significant attention in many areas. Critical requirements on reliability, fault tolerance and security highlight the necessity of SIP robustness testing. There are only a few researches on SIP robustness testing. The biggest challenge is the anomalous message generation. This paper proposes a method and architecture for SIP robustness...
