The prefrontal cortex is the superlative structure of brain that needs the longest developmental and maturational duration that highlights the region of attention deficit hyperactivity disorder (ADHD) in neuroimaging studies. Prefrontal cortex functions generate enormously complex and its abundant feedback neurocircuitries with subcortical structures such(More)
—IPv4 addresses will be soon exhausted while more and more users are pouring into the Internet. It is commonly understood that IPv6 is definitely necessary for connecting new users, but lack of resources in current IPv6 world discourages providers from developing their IPv6 market. Address and packet translations are considered necessary for Internet(More)
In this paper, we present Content-Oriented Network with Indexed Caching (CONIC), a deployable and self-scaling architecture to exploit spare storage and bandwidth from end-systems to eliminate redundant traffic and enable efficient and fast access to content. Our trace-driven simulation indicates that CONIC can reduce 25% to 50% traffic(More)
It becomes apparent that content should be center to the model of information access in the current Internet, which results in research efforts been put together as content-oriented network architectures. In light of our observation that in practice it is not feasible to replace the current Internet architecture with a clean-slate one and that it is the(More)
Research efforts have been put into content retrieval in the Internet, ranging from traditional web proxy to recent content-oriented network architectures. With the emerging trends of uploading large user-generated content, we argue that Internet should not only aid end users in downloading content from steadily available servers but also facilitate(More)
Despite the rapid progress of Information-Centric Network (ICN) research in the last few years, its key component route-by-name faces feasibility and efficiency challenges since we have to deal with a large number of information objects. In this article, we take a practical approach to the challenge of feasible and efficient name resolution service. Because(More)
Inter-domain routing is suffering from the lack of identifiers for the rapidly growing number of autonomous systems (AS), and therefore the 4-byte AS number has been proposed along with the transition scenario. In a partial deployment environment, 4-byte-enabled border gateway protocol (BGP) speakers have to exchange AS path vector with the old, 2-byte-only(More)
Today's fault detection in commercial networks is still done in an inefficient way with alarms and threshold violations that treat measured indexes separately. To provide a practical network fault detection approach for the actual network operation, we investigate many actual network fault occurrences, and discover that many network faults can be(More)
