Pattern matching is one of the most important components for the content inspection based applications of network security, and it requires well designed algorithms and architectures to keep up with the increasing network speed. For most of the solutions, AC and its derivative algorithms are widely used. They are based on the DFA model but utilize large(More)
Named Data Networking (NDN) is a recently proposed general- purpose network architecture that leverages the strengths of Internet architecture while aiming to address its weaknesses. NDN names packets rather than end-hosts, and most of NDN's characteristics are a consequence of this fact. In this paper, we focus on the packet forwarding model of NDN. Each(More)
NDN Forwarding Daemon (NFD) is a network forwarder that implements the Named Data Networking (NDN) protocol. NFD is designed with modularity and extensibility in mind to enable easy experiments with new protocol features, algorithms, and applications for NDN. To help developers extend and improve NFD, this document explains NFD’s internals including the(More)
Named-based packet forwarding represents a core characteristic of many information-centric networking architectures. IP-inspired forwarding methods are not suitable because a) name-based forwarding must support variable-length keys of unbounded length, and b) namespaces for data are substantially larger than the global address prefix rulesets used in(More)
In this paper, we present a novel adaptive GOP structure(AGS) for H.264/SVC. Proposed method adaptively defines the GOP structure by analyzing the input sequence characters. The accumulated difference of luminance pixel components is utilized to set a threshold for adaptive GOP size definition. Another scene change detection method is also proposed to(More)
In this paper, a high-performance multiplierless VLSI architecture for the transform applied in the emerging video coding standard-High Efficiency Video Coding (HEVC) is presented. The proposed architecture can support a variety of transform sizes from 4x4 to 32x32, and some simplification strategies are adopted during the implementation, such as reusing(More)
Although several researchers have posited relationships between rater prior experiences and rater backgrounds and their performance in operational scoring projects, very little empirical research exists to address this topic. This report summarizes how the background characteristics (demographics and professional experiences) of two samples of raters (one(More)
