Siendo los Grids sistemas extremadamente distribuidos, los requerimientos en la red de interconexión se deberıan tener en cuenta cuando se realicen tareas como por ejemplo la planificación, migración o monitorización de trabajos.

This is achieved by means of a scheduling algorithm, which decides which computing resource will execute each users' jobs. This task (the scheduling of jobs to computing resources) is done by taking into account the quality of the network links and their level of utilization. The purpose of this paper is to present an scheduling algorithm aimed at improving the network Quality of Service (QoS) in a Grid system, and demonstrate its usefulness by means of realistic Grid network simulations.

This is the case of public cloud infrastructures, where a given number and type of virtual machines (in short VMs) are instantiated during a specified time, being this reflected in the final budget. With this in mind, this paper introduces and validates iCanCloud, a novel simulator of cloud infrastructures with remarkable features such as flexibility, scalability, performance and usability. Furthermore, the iCanCloud simulator has been built on the following design principles: (1) it's targeted to conduct large experiments, as opposed to others simulators from literature; (2) it provides a flexible and fully customizable global hypervisor for integrating any cloud brokering policy; (3) it reproduces the instance types provided by a given cloud infrastructure; and finally, (4) it contains a user-friendly GUI for configuring and launching simulations, that goes from a single VM to large cloud computing systems composed of thousands of machines.

Por esto, varias propuestas se han presentado con este fin. Este trabajo presenta una evaluación de prestaciones de un meta-planificador autónomo consciente de la red (Autonomic Network-aware Meta-scheduler, ANM), comparado con otro meta-planificador consciente de la red (Gridbus Broker).
