Virtualizing and sharing networked resources have become a growing trend that reshapes the computing and networking architectures. Embedding multiple virtual networks (VNs) on a shared substrate is a challenging problem on cloud computing platforms and large-scale sliceable network testbeds. In this paper we apply the Markov Random Walk (RW) model to rank a(More)
Deep Packet Inspection (DPI) refers to examining both packet header and payload to look for predefined patterns, which is essential for network security, intrusion detection and content-aware switch etc. The increasing line speed and expanding pattern sets make DPI a challenging task. Network Processors (NPs) are chosen to perform DPI due to their packet(More)
Deep Packet Inspection (DPI)has been widely adopted in detecting network threats such as intrusion, viruses and spam. It is challenging, however, to achieve high speed DPI due to the expanding rule sets and ever increasing line rates. A key issue is that the size of the finite automata falls beyond the capacity of on-chip memory thus incurring expensive(More)
Network processors (NPs) have emerged as successful platforms for providing both high performance and flexibility in building powerful routers. Typical NPs incorporate multiprocessing and multithreading to achieve maximum parallel processing capabilities. We observed that under low incoming traffic rates, processing elements (PEs) in an NP are idle for most(More)
—Droplet-based " digital " microfluidics technology has now come of age and software-controlled biochips for healthcare applications are starting to emerge. However, today's digital microfluidic biochips suffer from the drawback that there is no feedback to the control software from the underlying hardware platform. Due to the lack of precision inherent in(More)
