Many long-running network analytics applications impose a high-throughput and high reliability requirements on stream processing systems. However, previous stream processing systems cannot sustain high-speed traffic at the core router level. Furthermore, their fault-tolerant schemes cannot provide strong consistency which is essential for network analytics. In this paper, we present the design and implementation of SAND, a fault-tolerant distributed stream processing system for network

We prove our fault-tolerant scheme provides strong consistency even under multiple node failure. We implement several real-world network analytics applications on SAND, evaluate their performance using network traffic captured from commercial cellular core networks, and demonstrate that SAND can sustain high-speed network traffic and that our fault-tolerant scheme is efficient.
