Programmable routers supporting virtualization are a key building block for bridging the gap between new Internet protocols and their deployment in real operational networks. This article presents the design and implementation of PEARL, a ProgrammablE virtuAl Router pLatform with relatively high-performance. It offers high flexibility by allowing users to(More)
Inflammatory activation of monocytes is an essential part of both innate immune responses and the pathogenesis of conditions such as atherosclerosis. However, the mechanisms which modulate the response of monocytes to inflammatory stimuli are still poorly understood. Here, we report that tribbles-2 (trb-2) is a novel regulator of inflammatory activation of(More)
OpenFlow is one of the most potential technique to enable innovation in network. To enable OpenFlow more flexibility and high-efficiency, multi-table pipeline has been introduced in OpenFlow. A HAL(Hardware Abstraction Layer) is proposed to address the incompatibility of flow table pipeline between legacy switch hardware and the controller. However, the(More)
Spatio-temporal regulation of intracellular signalling networks is key to normal cellular physiology; dysregulation of which leads to disease. The family of three mammalian tribbles proteins has emerged as an important controller of signalling via regulating the activity of mitogen activated protein kinases (MAPK), the PI3-kinase induced signalling network(More)
—Packet classification has been studied extensively in the past decade. While many efficient algorithms have been proposed, the lack of deterministic performance has hindered the adoption and deployment of these algorithms: the expensive and power-hungry TCAM is still the de facto standard solution for packet classification. In this work, in contrast to(More)
—In recent years, there has been a growing interest in multi/many core processors as a target architecture for high performance software router. This is a clear difference from the previous trend to use dedicated network processors and hardware components. Because of its key position in routers, hardware IP lookup implementation has been intensively studied(More)
Network virtualization which enables the coexistence of multiple networks in shared infrastructure adds extra requirements on data plane of router. Software based virtual data plane is inferior in performance , whereas, hardware based virtual data plane is hard to achieve flexibility and scalability. In this paper, using FPGA (Field Program Gate Array) and(More)
In this paper, we evaluate the impact of selfish behavior through a game-theoretic analysis of TCP Vegas and FAST TCP. By theoretical analysis, we obtain the Nash Equilibrium in these games and study the loss of efficiency under Nash Equilibrium. Our results show that if the users are selfish, then the efficiency of the network as a whole relies on the(More)
