RSS patternReconfiguration of MPLS/WDM Networks Using Simulation-Based Markov Decision Processes
White Paper Previous work considered total reconfiguration of the network, branch exchanges or addition and deletion of lightpaths when the traffic pattern changes. This paper presents a new approach to the problem of logical topology reconfiguration in... [18 Jul 2008]
Applying a Pattern Language to Develop Application-Level Gateways
White Paper Successful developers resolve these challenges by applying appropriate patterns and pattern languages. The primary contribution of this paper is to describe a pattern language that underlies object-oriented communication software. [11 Jul 2008]
Performance and Scalability of EJB Applications
White Paper The fourth version applies the session façade pattern, using session beans as a façade to access entity beans. The last version uses EJB 2.0 local interfaces with the session façade pattern. This paper investigate the combined effect of... [11 Jul 2008]
pathChirp: Efficient Available Bandwidth Estimation for Network Paths
White Paper Based on the concept of "Self-induced congestion," pathChirp features an exponential flight pattern of probes one calls a chirp. This paper presents pathChirp, a new active probing tool for estimating the available bandwidth on a communication... [11 Jul 2008]
A Novel Microstrip Patch Antenna With Large Impedance Bandwidth in VHF/UHF Range
White Paper Therefore the beam pattern shows a null in the broadside direction. In this paper a novel antenna is presented. This antenna, employing microstrip circular disc as radiator is seen to perform over a large impedance bandwidth (130MHz to 876 MHz). [11 Jul 2008]
Restoration Algorithms for Virtual Private Networks in the Hose Model
White Paper In the hose model bandwidth is reserved for traffic aggregates instead of pairwise specifications to allow any traffic pattern among the VPN endpoints. A Virtual Private Network (VPN) aims to emulate the services provided by a private network over... [11 Jul 2008]
Optimizing Pattern Matching for Intrusion Detection
White Paper A memory efficient variant uses sparse matrix storage to reduce memory requirements and further improve performance on large pattern groups. Intrusion Detection Systems are very specialized applications that require real-time pattern matching... [10 Jul 2008]
Arbutus: Network-Layer Load Balancing for Wireless Sensor Networks
White Paper The hot spot problem is a typical byproduct of the many-to-one traffic pattern that characterizes most wireless sensor networks: the nodes with the best channel to the sink are overloaded with traffic from the rest of the network and experience a... [10 Jul 2008]
Dynamic Load Balancing Algorithms for Sequence Mining
White Paper This paper presents a parallel formulation of a serial sequential pattern discovery algorithm based on tree projection that uses a novel dynamic load balancing algorithm which is well suited for distributed memory parallel computers. [10 Jul 2008]
Fusion of Multiple Classifiers for Intrusion Detection in Computer Networks
White Paper In this paper, a pattern recognition approach to network intrusion detection based on the fusion of multiple classifiers is proposed. The security of computer networks plays a strategic role in modern computer systems. [10 Jul 2008]
Sparta - A Mobile Agent Based Intrusion Detection System.
White Paper A simple pattern language is designed in order to express offending event correlations in a declarative manner. Many companies employ a variety of tools to enforce their often vague security policies. [10 Jul 2008]
High-Throughput Linked-Pattern Matching for Intrusion Detection Systems
White Paper This paper presents hardware architecture for highly efficient intrusion detection systems. In addition, a software tool for automatically generating the hardware is presented. Intrusion detection for network security is a compute-intensive... [09 Jul 2008]
Close the Zero-Hour Gap: Protection from Emerging Virus Threats
White Paper The latest advances in network traffic analysis and recurrent pattern detection. To exploit the "zero hour gap," or the time it takes to identify attacking malware and write signatures that detect and neutralize it, virus writers are using several... [09 Jul 2008]
Fast and Scalable Pattern Matching for Network Intrusion Detection Systems
White Paper High-speed packet content inspection and filtering devices rely on a fast multi-pattern matching algorithm which is used to detect predefined keywords or signatures in the packets. Multi-pattern matching is known to require intensive memory... [05 Jul 2008]
An Enhanced Support Vector Machine Model for Intrusion Detection
White Paper Support Vector Machines (SVM) as a classical pattern recognition tool has been widely used for intrusion detection. Design and implementation of intrusion detection systems remain an important research issue in order to maintain proper net-work... [05 Jul 2008]
