Implementing On-line Sketch-Based Change Detection on a NetFPGA Platform
نویسندگان
چکیده
Sketch-based algorithms are widely applied in various networking applications. In this paper, we present a compact implementation for on-line traffic change detection on a NetFPGA platform. The system utilizes a straight forward scheme to reveal the key of flow with tradeoff on the accuracy for hardware simplicity. It is capable of digesting traffic up to 4Gbps line rate with accuracy needed based on the available memory on-board.

This paper designs a novel security system on NetFPGA platform and Virtex5-LX110T using embedded soft-core technology. The system consists of two subsystems. The first one is a mainly used to protection subnets, which is implemented on NetFPGA board and the second one is a network intrusion detection system (NIDS) which is implemented on Xilinx Virtex5-LX110T board. Moreover, the two subsystems...

We present an implementation of NAT (Network Address Translation) for the NetFPGA platform capable of line-rate Gigabit Ethernet. Our implementation features RAM and CAM (Random Access and Content Addressable) memories for a fast and efficient NAT table. Several simulation and regression tests are included.
متن کاملA Network Emulator on the NetFPGA Platform
Network emulators play an important role when researchers want to evaluate the performance of newly designed protocols or network mechanisms instead of deploying them in real networks, because network emulators can provide appropriate network situations, (for example, delay, bottleneck bandwidth and packet loss) needed for experiments through easy control ‘knobs’. In this paper, we have impleme...

متن کاملPERFORMANCE COMPARISON BETWEEN THE CLICK MODULAR Router and the NetFPGA Router
1 It is possible to forward minimum-sized packets at rates of hundreds of Mbps using commodity hardware and Linux. We had a preference for the Click Modular Router platform due its flexibility and the fact that it claimed to have equal or higher performance than native forwarding if used with its polling drivers. Moreover, the NetFPGA is an open networking platform accelerator that enables rese...
