By Carlos Guerrero,Carlos Juiz,Ramon Puigjaner
Issue Date:August 2011
pp. 310-313
The performance of web caches, in Web Content Management Systems, can be improved by assembling only some of the content elements of a web page in the application server, and finishing the assembling process in the cache proxy. Due to this, the cache is ab...

Found in: Complex, Intelligent and Software Intensive Systems, International Conference
By Isaac Lera, Carlos Juiz, Ramon Puigjaner
Issue Date:February 2010
pp. 956-961
Ontology Matching (OM) consists of set of processes that decide and establish if ontology elements share lexical or semantic relationships. For a correct alignment, when we establish semantic relationships, it is necessary to find out the meaning of the el...
 
Scalable QoS Content-Aware Load Balancing Algorithm for a Web Switch Based on Classical Policies
Found in: Advanced Information Networking and Applications, International Conference on

Performance Analysis of Pools in Soft Real-Time Design Architectures
Found in: Modeling, Analysis, and Simulation of Computer Systems, International Symposium on
By Carlos Juiz, Ramon Puigjaner, Harry Perros
Issue Date:August 2001
pp. 0015
Abstract: Architectures for the design of soft real-time systems typically do not facilitate the use of performance tools that will enable a designer to analyse the performance of the system that is being designed. Intercommunication data areas, whose beha...
 
Performance Analysis of Multiclass Data Transfer Elements in Soft Real-Time Systems
Found in: Engineering of Computer-Based Systems, IEEE International Conference on the
By Carlos Juiz, Ramon Puigjaner
Issue Date:March 1999
pp. 152
Soft real-time systems are normally defined as those which are having performance constraints on several time measures. Usually, design methods for large real-time systems do not provide any help in performance analysis and estimation of the system which i...
 
Comparison of Predictive Techniques in Cluster-Based Network Servers with Resource Allocation
Found in: Modeling, Analysis, and Simulation of Computer Systems, International Symposium on
By Katja Gilly, Salvador Alcaraz, Carlos Juiz, Ramon Puigjaner
Issue Date:October 2004
pp. 545-552
Predictive algorithms play a crucial role in system management by alerting to future events that may degrade the global performance of the system. Our paper proposes a predictive algorithm for a web switch that manages a cluster of web servers. Several thr...
