Mejorar ancho de banda del XP Professional

Mejorar ancho de banda del XP Professional

Windows XP se reserva el 20% del ancho de banda disponible, con el fin de ejecutar aplicaciones especiales. La “retención” se produce mediante el denominado el programador de paquetes QoS (Quality of Service – Calidad del Servicio), encargado de la optimización de redes locales.
Sin embargo, para los usuarios privados, que sólo tienen un PC en casa, QoS no es una función necesaria; sino todo lo contrario. Windows XP reserva el 20% del ancho de banda aunque el usuario cancele la función QoS. También se puede optar por desintalar el Programador de paquetes QoS si no tenemos ninguna Red Local.
1) Entrar como administrador.
2) Inicio, ejecutar, escribid: gpedit.msc
3) Aparecen las directivas de grupo, id a Configuración de Equipo.
4) Plantillas Administrativas
5) Red (Network)
6) Programador de Paquetes Qos
7) Doble click en Limitar el ancho de banda reservado
8) Habilitarlo y poner el 0% en Límite de Ancho de Banda.
9) Aplicar y Aceptar
10) Id a propiedades red y comprobad que está marcado el Programador de Paquetes Qos.

Mejorar las transferencias en red de archivos

Mejorar las transferencias en red de archivos

Windows normalmente limitará la cantidad de memoria RAM que el sistema podrá utilizar para las operaciones de entrada y salida de datos en conexiones de red, algo que podemos modificar mediante la edición del registro
La utilidad de este ajuste cuestionable para usuarios que no tengan instalado en el sistema algún tipo de servidor, ya que básicamente este ajuste mejora el rendimiento de entrada/ salida del ordenador cuando se están realizando una cantidad grande de transferencias de archivos y operaciones similares. Este ajuste no hará mucho en sistemas que no tengan grandes cantidades de memoria, pero sistemas con más de 256 Mb de RAM generalmente encontrarán una mejora en el rendimiento estableciendo este valor entre 16 y 32 Mb. El valor por defecto es 0.5Mb (512Kb). Para modificar el ajuste automático de esta configuración, iniciaremos la herramienta de edición del registro de sistema, con el comando “regedit.exe” en el menú Inicio/Ejecutar. Localizaremos la clave HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management y crearemos o modificaremos el valor DWORD de nombre “IoPageLockLimit” (sin las comillas) con un número, cuyo valor será equivalente al máximo de bytes que se utilizarán para las operaciones de entrada y salida, de forma que tendremos que multiplicar el número de megabytes x 1024 x 1024
NOTA: Modificar este ajuste puede causar problemas de estabilidad con dispositivos de sistema, como problemas relacionados con OpenGL o SCSI, en cuyo caso volveremos al ajuste predeterminado.

Editor de registro. Para ello pinchamos en INICIO -> Ejecutar: "regedit" (sin comillas) y le damos a enter. Entramos luego hasta el nivel HKEY_CURRENT_USER -> Control Panel -> Desktop y localizamos allí la clave "WaitToKillAppTimeout" y hacemos doble clic sobre ella. A continuación cambiamos el valor de 20.000 (que ya trae por defecto) por el de 4.000. Ahora, y sin salir del editor, accedemos a HKEY_LOCAL_MACHINE -> System -> Current Control -> Control, para localizar de nuevo la clave "WaitToKillAppTimeout" y repitiendo la misma operación de antes cambiamos el valor de 20.000 a 4.000.

TIPO DE FORMATEO DE DISCOS DUROS

Hay dos formas para formatear el disco duro. Una es haciendo un formateo a bajo nivel y la otra a alto nivel.

Bajo Nivel: Consiste en colocar marcas en la superficie magnética para dividirlo en sectores físicos, los cuales pueden ser luego referenciados indicando la cabeza lectora, el sector y cilindro que se desea leer. Reescribe la geometría del disco duro, el MBR y define el tamaño de los sectores de acuerdo a la densidad del disco duro. Este proceso puede tardar muchas horas dependiendo de la densidad del disco. Aunque cuando sale de fábrica viene ya formateado a bajo nivel, hay que darle de nuevo un formateo al tener que crear un sistema de archivos.

Este sistema de formateo es un poco peligroso ya que podemos “estropear” el disco duro si mediante el proceso se detiene o si no se utiliza una herramienta adecuada. Para ello, muchos fabricantes dejan a nuestra disponibilidad en su web, su herramienta para este tipo de proceso. Además, es muy importante saber que al realizar un formateo a bajo nivel, toda la información que había en el disco duro ha sido borrada totalmente, sin recuperación alguna.

También, con este formateo puedes llegar a “reparar” el disco duro si tenía sectores defectuosos.

Alto Nivel: Con este sistema no se llegan a perder los datos que hay almacenados en el disco duro, lo que realmente hace es borrar las tablas de partición que albergan la información de cómo y dónde se encuentran los datos en el disco duro. Concretamente es el índice maestro de arranque (MBR) que es un sector del disco que inicia en 001.

Hay dos formas de hacerlo, de forma rápida o completa. Tanto uno como el otro hacen lo descrito anteriormente, borra la tabla de partición, pero la diferencia es que el completo, además de borrar la tabla, examina todos los sectores del disco duro en busca de errores.

PRACTICA 4 PROTOCOLO RIP

PRACTICA 4 INTERCONEXION DE REDES BOSON NETSIM v5.27

Esta practica se trata de una simulación de una red con las herramientas Boson NetSim v5.27. En este software simularemos una red que consta de 4 routers (modelo 2505) A cada uno de los routers secundarios se le ha conectado un SWITCH (modelo 1912) de los que colgarán los terminales. y 4 computadoras.

Con enable entramos a modo de configuracion. Config T nos permite introducir comandos de configuración, tales como hostname (nombre del router), o enable password ortigoza que hace que la contraseña para configurarlos sea a partir de este momento, ortigoza.

Los routers están conectados entre si por los interfaces. estos son Serial 0 y Serial 1 para conectar routers entre sí (s1 con s1 no es posible conectarse, ya que uno debe ser el DCE y el otro es el DTE), y los Ethernet 0 que son los que se encargarán de conectarse a los switches.
