This paper develops an empirical profile of BGP prefix announcements that originate from multiple ASes, so-called MOAS announcements. Analysis of Oregon RouteViews data over one year shows that a small fraction of prefixes are responsible for a very large fraction of all origin AS transitions observed at RouteViews. Moreover, these heavy-hitter prefixes oscillated between two origin ASes. The p...

In recent decades, spearfishing with SCUBA has emerged as an efficient method for targeting reef fish in deeper waters. However, deeper waters are increasingly recognised as a potential source of refuge that may help sustain fishery resources. We used a combination of historical catch data over a 20-year time period and fishery-independent surveys to investigate the effects of SCUBA spearfishin...

Parametric Stereo (PS) is an audio coding object of MPEG-4 HE-AAC v2 which utilized the Spatial Audio Coding (SAC) technique to enhance the compressing efficiency. However, the complexity at decoder is higher than that at encoder in PS. In this paper, we proposed a low complexity decoding scheme in PS. To take advantage of SAC, the encoder additionally extracts and transmits the parameters of r...

IP Routers use sophisticated forwarding table (FIB) lookup algorithms that minimize lookup time, storage, and update time. This paper presents SMALTA, a practical, near-optimal FIB aggregation scheme that shrinks forwarding table size without modifying routing semantics or the external behavior of routers, and without requiring changes to FIB lookup algorithms and associated hardware and softwa...
