Visão Geral

TCP / IP é o grupo mundialmente aceito de protocolos no núcleo da Internet e intranets organizacionais.

Uma sólida compreensão de cada um destes protocolos e como eles funcionam vai lhe dar a capacidade de implantar a rede mais eficaz para a sua organização.

Neste curso, você vai ganhar o conhecimento e as habilidades necessárias para instalar, configurar, um apoio essencial e solucionar problemas de rede TCP / IP-based.

Objetivo

• Os elementos essenciais do conjunto de protocolos TCP / IP
• Instalar e configurar o TCP / IP em uma rede de sala de aula ao vivo
• As funções dos vários dispositivos de uma rede TCP / IP
• Endereçamento IP e sub-redes, incluindo comprimento variável de sub-rede de mascaramento (VLSM)
• Sub-rede de uma rede IP e implementar os endereços resultantes
• Detalhes da ARP, IP, ICMP, TCP e UDP – suas funções e relações
• Automatizar a atribuição de endereços e resolução de nomes usando DHCP e DDNS
• roteamento IP e os protocolos que o suportam, como RIP e OSPF
• Como aplicações como FTP, HTTP, Telnet, e outros trabalham em uma rede TCP / IP
• Funções do IPv6 e seus protocolos
• Funções e capacidades de multicasting, Voz sobre IP, e e-mail
• O uso de um analisador de protocolo para isolar e solucionar problemas de rede
• Solucionar problemas em cada camada de uma rede TCP / IP

Publico Alvo

• Quem é responsável pela concepção, instalação, configuração e manutenção de redes TCP / IP ou que precisar de compreender estruturas protocolo TCP / IP e funções irão beneficiar com este curso. Este curso também proporciona uma excelente preparação para a formação de redes mais avançado
