This paper introduces AtoZ, an automatic traffic organizer that provides endusers with control of how their applications use network resources. Such an approach contrasts with the moves of many ISPs towards network-wide application throttling and provider-centric control of an application’s network-usage. AtoZ provides seamless per-application traffic-organizing on gigabit links, with minimal p...

As FPGA-based systems including soft processors become increasingly common, we are motivated to better understand the architectural trade-offs and improve the efficiency of these systems. The traditional forwarding and routing are now well understood problems that can be accomplished at line speed by FPGAs but more complex applications are best described in a high-level software executing on a ...

Both in academic and industrial research, building a green energy-saving network has become a hot topic. Combined with hardware division and adaptive algorithm, this paper proposes an adaptive frequency control mechanism based on traffic to reduce power consumption. By calculating real-time traffic, the network device can adjust its operating frequency. On the premise of maintaining network per...

An emerging class of distributed applications such as graph processing and key-value store require fine grained non-uniform memory access and communication, which commodity networking infrastructure is ill-equipped to handle. By batching messages on the end host we can increase bandwidth utilization at the cost of latency and memory. However, by batching messages in the network instead of exclu...

Data plane programmability brings network flexibility to a new level. However, it introduces the complexity of data path's program as factor that influences packet forwarding latency and thus devices' performance. Accurate identification relation between path enables design management networks with predictable In this article, we leverage characteristics P4 programming language provide method f...
