A problem of research on overlay network is lack of testing platform. Recent research has shown that one can use distributed hash tables (DHTs) to build scalable, robust and efficient applications. However, large-scale distributed systems are hard to deploy, nor are DHTs . Open DHT is a publicly accessible DHT service. In contrast to the usual DHT model,… (More)
We present a typed process calculus for dynamic web data. It features web data in networks, hyperlinks, service calls, scripts, dynamically accessing data and typing. In this paper, a typing system disciplines data handing at the level of channels and processes. We proved subject reduction theorem which says that well-type will be preserved by reduction in… (More)
This paper presents an encoding scheme for pair sharing. Pair sharing relations and abstract operations required for a pair sharing analysis are encoded as Boolean functions and operations on Boolean functions. Preliminary experimental results with a prototype implementation are presented.
In order to guarantee continuous delivery of video streaming over best-effort (BE) forwarding network, some quality-of-service (QoS) strategies such as RSVP and DiffServ must be used to improve the transmission performance. However, these methods are too difficult to be employed in practical applications since their technical complexity. In this paper, we… (More)
Bloom filters are used for resource routing and distance-weighted Bloom filters (dwBFs) are used as a concise representation of routing information for scattered resources in overlay networks. Today's DHT-based P2P lookups are always influenced by unnecessarily long routers in the underlay network. The reason is that the false positives appearing in DHT… (More)
