    Network Simulation on NS-2 6 days left

    Hi, I need to have a network simulation on (NS-2). The detail is as follow: we'll be using the wireless network (P2P Mobile devices) with double layered approach (super nodes & sub nodes) make the cluster for the nodes such that each cluster has a super cluster (Super node is selected from among all the nodes such that the movement of the node is least as compare to the rest of the nodes in the cluster - will provide the formula for this) each super node will have a table that'll contain the list of files for all the node in that cluster. i.e: <NodeID, FileID>, so whenever a node requests for a file, the request will directly go to the super node where super node will return the NodeID for that particular request(FileID). If the file does not exist in the super Node, super node will send request to the adjacent cluster via relay node (node in b/w both clusters) The Node may leave or join at any time, So, need to re generate the file table periodically.

    I have problems managing Integrated Lights Out, my server has ILO2 installed, suddenly the access just died, it does not show as an active device on the gateway. I also have connection problem from the internet using Remote Desktop, and obviously can't reach ILO. Had multiple security warnings after the last configuration effort, so the server might need certificates. The server runs Windows 2016.

    Descripción del proyecto: Actualmente trabajamos sobre dos servidores Cloud gestionados idénticos, pruebas y producción. En ellos trabajamos con un CRM propio que sigue en desarrollo, pero estamos limitados y necesitamos más control y más herramientas (backup por ejemplo). Ambos servidores son de 4 cores, 8 Gb de RAM y 300 Gb. de disco SSD. El servidor de correo y los dominios, así como los certificados SSL están en otra ubicación. Tareas Dimensionar y optimizar los recursos del servidor en base al uso que se dará en unos meses al CRM (el segundo servidor será una imagen de éste). Orientar sobre proveedores. Estamos interesados en saber cual sería el coste para un servidor S3, ya que las imágenes las trasladaremos de todas formas a uno de estos servidores. Configurar el servidor en base a nuestras necesidades y redimensionarlo en función de los datos reales de uso. Todo ello realizado en conexión con nuestro técnico para que aprenda y pueda resolver pequeñas modificaciones como asociar un nuevo dominio o crear una nueva tarea Cron. Necesitaremos poder crear imágenes, backups (BBDD y HD), balanceadores de carga (en un futuro próximo), tareas Cron, alertas, seguimiento del uso de procesador y memoria, etc. Pensamos tanto en un buen Cloud como en un servidor dedicado. Se solicita para la candidatura que nos informen detalladamente de: - proveedor que aconsejan y por qué (calidad y beneficios de sus servidores) - servicios que hay que contratar y coste de cada uno de ellos mensual (si se ha trabajado con S3 detallar también lo mismo para un S3 si no es la opción recomendada) - coste de su trabajo cerrado, no por hora, contando que será realizado, siempre que no haya esperas de activación de servicios, conectado con nuestro técnico para que pueda seguir el proceso y que pueda solicitar aclaraciones. - coste por hora de algunos cambios o actualizaciones que se requieran en un futuro. - coste por hora si se ha de realizar fuera del horario laboral de los usuarios de CRM . El tiempo nos apremia, así que si estás interesado no tardes en contestar ;)
