The results and comparison of the simulation of a new heuristic algorithm called Snake One are presented. The comparison is made with three heuristic algorithms, Genetic Algorithms, Simulated Annealing, and Tabu Search, using blocking probability and network utilization as standard indicators. The simulation was made on the WDM NSFNET under dynamic traffic conditions. The results show a substantial decrease of blocking, but this causes a relative growth of network utilization. There are also load intervals at which its performance improves, decreasing the number of blocked requests.

En este artículo se presentan los resultados y la comparación de la simulación de un nuevo algoritmo heurístico llamado Serpiente Uno. La comparación se hace con tres algoritmos heurísticos: Algoritmos Genéticos, Simulated Annealing y Búsqueda Tabú, utili-zando como indicadores estándar la probabilidad de bloqueo  y la  utilización de la red. La simulación se realizó sobre la WDM NSFNET en condiciones de tráfico dinámicos. Los resultados muestran una disminución sustancial de la probabilidad de bloqueo. Sin embargo, esto causa un aumento relativo de la utilización de la red. También hay intervalos de carga donde el rendimiento me-jora, disminuyendo el número de solicitudes bloqueadas.
