Driven by the advances in location positioning techniques and the popularity of location sharing services, semantic enriched trajectory data have become unprecedentedly available. While finding relevant Point-of-Interest (POIs) based on users' locations and query keywords has been extensively studied in the past years, it is largely untouched to explore the keyword queries in the context of semantic...
The network resource competition of today' data enters is extremely intense between long-lived elephant flows and latency-sensitive mice flows. Achieving both goals of high throughput and low latency respectively for the two types of flows requires compromise, which recent research has not successfully solved mainly due to the transfer of elephant and mice flows on shared links without any differentiation...
The efficiency of spatial query processing is crucial for many applications such as location-based services. In spatial networks, queries like k-NN queries are all based on network distance evaluation. Classic solutions for these queries rely on network expansion and are not efficient enough for large networks. Some approaches have improved the query efficiency but brought considerable space cost...
Address auto-configuration is a key problem in data center networks, where servers and switches encode topology information into their addresses for routing. A recent work DAC [2] has been introduced to address this problem. Without malfunctions, DAC can auto-configure all the devices quickly. But in case of malfunctions, DAC requires significant human efforts to correct malfunctions and it can cause...
Pattern Matching (PM) is a key building block for many emerging network applications. Modern multicore platforms are becoming performance competitive with traditional hardware solutions, which are expensive and hard to adapt to the rapid diversification of Internet applications. However, due to uneven network flow sizes and the need to retain packet order within each flow, traditional parallel processing...
Pattern Matching (PM) over network packet flows for Network Intrusion Detection/Prevention System is becoming more and more performance sensitive due to the rapid progress of Internet applications in terms of data volumes. Meanwhile, modern multicore platforms are becoming performance competitive with traditional hardware solutions for PM. But due to the unbalance of network flow sizes, traditional...
