A new intrusion detection mechanism in SELinux based on dual-Markov chain and triggered by critical system calls is put forward in this paper. The mechanism integrates access control with intrusion detection by Linux Security Module (LSM) in SELinux and considers both the global behaviour characteristics and local behaviour characteristics. Theoretical analysis and experimental results show that the...
Orthogonal Frequency Division Multiplexing (OFDM) has recently been proposed as a modulation technique for optical networks due to its higher spectral efficiency and superior impairment tolerance. There have been extensive studies on routing and spectrum assignment (RSA) of the OFDM-based elastic optical network, of which most focus on a single route for each lightpath service. In this paper, we study...
We consider a general form of routing, called limited multi-path routing, on extended generalized fat-trees where the number of paths between each pair of processing nodes is a parameter. Existing single-path routing and multi-path routing for such topologies are special cases of limited multi- path routing. We propose path calculation heuristics, including shift-1, disjoint, and random for limited...
The angularity of coarse aggregate is a key characteristic. The high-temperature stability, low temperature anti-cracking performance and moisture susceptibility of asphalt mixture are influenced greatly when coarse aggregates are used in the asphalt pavement. Three indexes were used for quantizing the angularity of coarse aggregate. They are FI (Form Index), Angularity GM (Gradient Method) and Angularity...
A HPN (hybrid Petri nets) traffic model, composed of discrete Petri nets and TdPN (timed Petri nets), is proposed for modeling dynamic traffic flows at non-signalized T-intersections in urban traffic networks. This model is used to solve two primary problems. One is how to formulate dynamic traffic flows at intersections. Another is how to simulate their behavior accurately and continuously. The discrete...
Round robin based packet schedulers generally have a low complexity and provide long-term fairness. The main limitation of such schemes is that they do not support short-term fairness. In this paper, we propose a new low complexity round robin scheduler, called Fair Round Robin (FRR), that overcomes this limitation. FRR has similar complexity and long-term fairness properties as the stratified round...
