This is a fantastic channel presenting a harmonio. O processo de desencapsulamento ocorre tanto na estao destino quanto nos vrios roteadores intermedirios. No entanto, como os datagramas IP devem ser encaminhados adiante nos roteadores intermedirios, a unidade de dados encapsulada no datagrama IP no sobe na pilha de protocolos. Em vez disso, o datagrama IP passa por um novo processo de encapsulamento.

Em conjunto, os processos de encapsulamento e desencapsulamento asseguram a correta comunicao entre entidades pares de uma dada camada, ou seja, a entidade destino sempre recebe uma cpia idntica da unidade de dados enviada pela entidade origem.

Por exemplo, o protocolo IP monta datagramas e solicita que sejam enviados camada de interface de rede. Alm disso, recebe e processa os datagramas IP extrados pela camada de interface de rede. Por outro lado, na recepo de datagramas IP, se a estao for o destino, o datagrama recebido localmente repassado camada de transporte.

Caso contrrio, o datagrama recebido roteado para a estao destino ou para outro roteador intermedirio. Ou seja, tais protocolos transportam unidades de dados diretamente entre as estaes origem e destino.

Portanto, apenas os Hosts A e B apresentam as camadas de aplicao e transporte. Dessa forma, as camadas inter-rede e interface de rede esto presentes nas estaes de origem e destino e nos vrios roteadores intermedirios. Entretanto, roteadores possuem apenas uma nica implementao da camada de rede, porque o protocolo IP adotado em toda a inter-rede para garantir a interoperabilidade dos vrios dispositivos.

Atividade: Capturando pacotes na rede Para exemplificar a interao dos protocolos e o processo de encapsulamento, vamos analisar um quadro capturado numa rede local Ethernet, durante uma sesso de um host com um servidor web que usa o protocolo HTTP de aplicao e o protocolo TCP de transporte.

Neste caso, ambos esto na mesma rede local. O programa utilizado para isso o analisador de rede Wireshark. O Wireshark pode ser obtido em www. Soluo A figura a seguir mostra a tela principal do Wireshark. Na parte superior esto os menus suspensos e logo abaixo a barra de ferramentas. Para abrir o arquivo de captura chamado Atividade1. Para esta anlise selecionamos o pacote no , que foi enviado do servidor web para o host do usurio.

Figura 4. Na janela inferior temos o contedo total do pacote bytes representado na forma hexadecimal do endereo x at o endereo x Cada camada, quando selecionada, faz com que os bytes correspondentes fiquem destacados na janela inferior. A figura a seguir mostra o cabealho da camada de enlace de dados com o tamanho de 14 bytes. Se tivssemos selecionado a camada fsica, todo o quadro estaria em destaque bytes.

As prximas figuras mostram em destaque os dados das camadas de rede, transporte e aplicao, respectivamente. Na figura a seguir esto destacados os bytes do cabealho do protocolo TCP 20 bytes. Finalmente, na prxima figura aparecem em destaque os bytes dos dados da aplicao. Note que esses dados tm o tamanho de 78 bytes, conforme informado pelo programa Wireshark, linha da camada de transporte, ltimo campo informado Len: Observe que, como o protocolo TCP o nico que faz a interface com a aplicao, somente ele poderia saber o tamanho do campo de dados da aplicao.

Clique em Opes, e em seguida em Executar como um usurio diferente; escolha o Nome de usurio como root se j no estiver selecionado e a senha correspondente, conforme mostra a figura a seguir: Figura 4. Clique em Executar. O Wireshark ser iniciado em modo root. Para escolher uma interface de captura, clique no primeiro cone esquerda na barra de tarefas do Wireshark.

Dever ser mostrada uma tela semelhante da figura a seguir, onde deve ser selecionada a interface desejada. Clique em Start para que a captura seja iniciada automaticamente. Basta fazer um acesso qualquer internet e depois clicar no quarto cone da esquerda para a direita da barra de ferramentas, conforme a figura 4. Notao decimal pontuada Representao de um endereo IP na forma de quatro nmeros decimais separados por pontos. Os usurios veem a internet como uma rede virtual nica qual todos os dispositivos esto conectados.

Para possibilitar essa conexo, um mecanismo de endereamento universal deve ser adotado, permitindo a identificao individual e nica de cada dispositivo. Endereos IP so nmeros inteiros positivos de 32 bits. Portanto, existe um total de endereos possveis. Para facilitar a manipulao, os endereos IP so normalmente escritos com uma notao decimal pontuada dotted-decimal notation.

Cada nmero decimal est associado a um determinado byte do endereo e, portanto, varia entre 0 e A figura a seguir apresenta as notaes binria e decimal do endereo IP: Endereos IP no so atribudos diretamente s estaes e roteadores, mas s interfaces de rede desses dispositivos. Dessa forma, cada interface de estaes e roteadores deve possuir um endereo IP nico. Em vez de utilizar uma numerao puramente sequencial, os endereos IP adotam uma estrutura hierrquica que identifica as redes fsicas e as estaes interfaces nessas redes.

A razo dessa estruturao hierrquica realizar o roteamento baseado em redes, em vez de estaes. Essa abordagem reduz sensivelmente a quantidade de informaes do roteamento e o torna mais eficiente. Para representar essa hierarquia, todo endereo IP dividido em duas partes:. Roteamento baseado em redes As informaes de roteamento apontam para as redes, e no para as estaes individuais.

Figura 5. A figura a seguir ilustra a estrutura hierrquica dos endereos IP: 0 Identificador de rede Identificador de estao Por exemplo, observe na figura a seguir que todas as interfaces conectadas s redes Rede1 e Rede2 compartilham prefixos de redes que identificam suas respectivas redes fsicas. Isso significa que as estaes E1 e E2 e o roteador R1 compartilham o prefixo Interfaces conectadas a diferentes redes fsicas podem possuir os mesmos identificadores de estao, pois seus prefixos de rede so diferentes e asseguram a unicidade de endereos.

Por exemplo, na Rede1, as estaes E1 e E2 e o roteador R1 possuem os identificadores de estao 1, 2 e 3, respectivamente.

J na Rede2, as estaes E3 e E4 e o roteador R1 possuem, tambm, os identificadores de estao 1, 2 e 3, respectivamente, mas os prefixos de rede so diferentes. Define onde termina o prefixo de rede e comea o identificador de estao. Para acomodar redes fsicas de diferentes tamanhos, o espao de endereos IP dividido em cinco classes de endereos, denominadas classes A, B, C, D e E.

Cada classe adota uma posio diferente para delimitar o prefixo de rede e o identificador de estao. A prxima figura ilustra as classes de endereos IP, cuja distino realizada por um cdigo fixo associado a cada classe nos primeiros bits do byte mais significativo chamada regra do primeiro octeto.

No lado direito da figura, o espao de endereos de cada classe apresentado. As redes que usam esse esquema padro de endereamento possuem uma arquitetura de endereamento classful, enquanto as que usam esquemas diferentes tm arquitetura de endereamento classless. Arquitetura de endereamento classful Esquema de endereamento que utiliza o conceito de classes de endereos A, B e C. Permite a adoo do esquema de endereamento de sub-redes, porm no permite o esquema de endereamento de super-redes.

Assim, podemos concluir que o total de redes classe A 27 primeiro bit do prefixo de rede sempre igual a 0 , com at estaes em cada rede; classe B os 16 primeiros bits representam o prefixo de rede e os outros 16 bits representam o identificador da estao. Nesse caso, o total de redes classe B dois primeiros bits do prefixo de rede fixados em 10 , com at estaes em cada rede; classe C possuem 24 bits que identificam a rede e apenas 8 bits que identificam a estao.

Assim, a quantidade de redes classe C , no mximo, de trs primeiros bits do prefixo de rede fixados em , com at 28 estaes em cada rede; classe D usados para suportar endereamento multicast, em que cada endereo associado a um grupo de estaes. Neste caso, pacotes destinados a um determinado endereo multicast so entregues s estaes que pertencem ao respectivo grupo.

O conjunto composto pelos 28 bits de um endereo classe D denominado identificador de grupo multicast. Ao contrrio das classes A, B e C, que so ditas unicast, endereos multicast no possuem qualquer estruturao.

Na prtica, endereamento multicast pode ser explorado. Arquitetura de endereamento classless Esquema de endereamento que no utiliza o conceito de classes de endereos. Permite a adoo do endereamento de super-redes, como tambm o endereamento de sub-redes. Considerando um endereo classe A, B ou C, para cada prefixo de rede, o espao de endereamento abrange os endereos possveis que podem ser expressos por meio da variao do identificador da estao, conforme exemplificado na tabela abaixo: Prefixo de rede 10 Endereos especiais Considerando o espao de endereamento das classes A, B e C, vrios desses endereos so reservados para determinadas finalidades: identificao de rede, broadcast, endereos privados, identificao de rota default, loopback.

Endereos de rede e broadcast Alm de serem utilizados para identificar estaes interfaces de estaes e roteadores de uma rede, os endereos IP servem para referenciar as prprias redes. Por isso, por conveno, qualquer endereo classe A, B ou C, cujo identificador de estao possua todos os bits iguais a 0, reservado para enderear a prpria rede, denominando-se, ento, endereo de rede. Assim, o identificador de estao com todos os bits iguais a 0 nunca atribudo a uma interface, conforme exemplificado na tabela seguinte: Classe A B C Prefixo de rede 10 Broadcast Tcnica que permite a entrega de cpias de um mesmo pacote a todas as estaes de uma determinada rede.

Endereo de broadcast direto Endereo IP especial cujo identificador de estao possui todos os bits iguais a 1. Uma vez que cada rede fsica possui um endereo de rede particular, o endereamento IP adota o conceito de broadcast direto. Para suportar o conceito de broadcast direto, o endereamento IP reserva um endereo especial em cada rede. Por conveno, qualquer endereo classe A, B, ou C, cujo identificador de estao possua todos os bits iguais a 1, reservado para representar o endereo de broadcast direto.

Assim, o identificador de estao com todos os bits iguais a 1 nunca deve ser atribudo a uma interface, conforme exemplificado na prxima tabela. Classe A B C Endereo de rede Desta forma, um endereo IP que contenha todos os bits do identificador de estao com valor 0 ou valor 1 no pode ser usado para identificar uma interface de rede. Essa regra chamada all bits 0 and 1 todos os bits zeros e uns. Ao contrrio de endereos de rede, que nunca so usados diretamente nos datagramas IP, endereos de broadcast direto podem ser usados em datagramas, permitindo ao roteador de entrada da rede destino realizar o broadcast do datagrama naquela rede.

Considerando as faixas de endereos das classes A, B e C, os endereos usveis so todos aqueles que podem ser atribudos s interfaces de estaes e roteadores.

Portanto, todos os endereos so usveis, exceto o primeiro endereo de rede e o ltimo endereo de broadcast direto. A tabela seguinte ilustra exemplos de endereos usveis para as classes A, B e C.

Classe A B C Prefixo de rede 10 Endereos de rede nunca so usados diretamente nos datagramas IP. Interface e endereo de loopback Para viabilizar um mecanismo de teste local de protocolos e servios, o conceito de interface de loopback suportado por diversas implementaes. O endereo de rede classe A Na prtica, geralmente, apenas o endereo Assim, qualquer datagrama IP destinado ao endereo Note que a interface de loopback no uma interface fsica, mas uma interface virtual.

Consequentemente impossvel enviar um datagrama IP para o endereo de loopback de outra estao. Interface de loopback Interface virtual que referencia a prpria estao. Endereo de loopback Endereo IP reservado Mscaras de rede As classes de endereos adotam diferentes posies para delimitar o prefixo de rede e o identificador de estao. Alm dos primeiros bits do prefixo de rede, o endereamento IP adota o conceito de mscara de rede para permitir que cada estao conhea o nmero de bits que identifica a rede fsica e a estao.

A prxima figura ilustra a estrutura de uma mscara de rede: 0 Mscara de rede Padro de 32 bits que contm bits 1 na posio do prefixo de rede e bits 0 na posio do identificador de estao. Assim, o endereo IP Considerando que os endereos de rede classe A, B e C possuem 8, 16 e 24 bits no prefixo de rede, as mscaras A figura a seguir exemplifica um endereo IP classe B Note a diviso entre os octetos de rede os 2 primeiros e os octetos de host os 2 ltimos. A tabela seguinte mostra exemplos de endereos IP das classes A, B e C e suas respectivas mscaras de rede.

Tabela 5. Encaminhamento de pacotes IP Estaes conectadas mesma rede fsica podem se comunicar diretamente. No entanto, estaes conectadas a redes fsicas diferentes devem enviar os datagramas IP por meio de roteadores intermedirios.

Entrega direta Ocorre quando as estaes de origem e destino esto conectadas na mesma rede fsica. Para exemplificar a entrega direta, considere duas estaes conectadas ao mesmo segmento de rede fsica Ethernet, conforme mostrado na prxima figura.

A estao Host A tem endereo IP: Nesse caso, o datagrama ir transportar os endereos IP das estaes de origem Mas surge um problema: a estao Host A no sabe o endereo fsico da estao Host B. Ela precisa desse endereo fsico para entregar o quadro diretamente. Para obter o endereo fsico do Host B, ela precisa usar o protocolo ARP Address Resolution Protocol que permite a qualquer estao da rede fazer uma consulta como a mostrada na figura anterior.

Somente a estao com o endereo IP: Nesta resposta chamada ARP Reply, que no broadcast, o Host B informa seu endereo fsico para que o Host A possa encapsular o datagrama IP no quadro da rede fsica e, ento, efetivamente transmiti-lo.

Quem tiver esse endereo IP, por favor informe seu endereo fsico. Esse quadro est mostrado em detalhes na prxima figura, onde foi selecionado o quadro 1 e a camada de enlace de dados. A figura a seguir mostra a resposta do Host B endereo IP: Note tambm que o Wireshark s mostra a camada fsica, a camada de enlace e o protocolo ARP, porque ainda no foi enviado nenhum datagrama IP.

Mais adiante veremos como examinar essa tabela. Comando ping Para testar se um determinado destino est operacional e pode ser alcanado atravs da rede, o comando ping envia mensagens ICMP Echo Request para o destino especificado. Se a resposta no for recebida, a estao origem pode concluir que o destino no est operacional ou no pode ser alcanado atravs da rede.

Nesse processo, o ping calcula o tempo de resposta round-trip , dando uma ideia da proximidade daquele destino. Este comando serve para verificar a conectividade entre origem e destino, no importando se ambos esto na mesma rede ou no. A origem calcula o tempo total de ida e volta round-trip e imprime uma linha com os resultados. Se o destino no existir, emitir uma mensagem de erro ICMP. A figura a seguir ilustra esse processo:. Para examinar o funcionamento desse processo, vamos usar o analisador de protocolo Wireshark, com o arquivo de captura Atividade2.

Os quadros 4 a 10 mostram todo o processo de troca de mensagens ICMP entre origem e destino. No nosso exemplo as estaes envolvidas tm os endereos IP: Observe que o Wireshark mostra no segundo quadro detalhamento das camadas de protocolos , 4 camadas: fsica, enlace de dados rede local Ethernet , rede datagrama IP e ICMP, que est usando os datagramas IP para transporte das suas mensagens.

Nesse exemplo, ambas as estaes esto na mesma rede. O que acontece se as estaes de origem e destino no estiverem na mesma rede? Entrega indireta Ocorre quando as estaes de origem e destino esto conectadas a redes fsicas distintas.

Ela pode ser representada como uma sequncia de entregas diretas. Inicialmente, a estao de origem entrega o datagrama a um roteador intermedirio que, por sua vez, entrega a outro roteador intermedirio e assim por diante, at que o ltimo roteador do caminho entrega o datagrama estao destino.

Para exemplificar a entrega indireta, considere duas estaes E1 e E4, conectadas a redes fsicas distintas por meio de um roteador R1, conforme mostrado na figura a seguir. Suponha que a estao E1 deseja enviar um datagrama IP para a estao E4. Nesse caso, o datagrama sempre transporta os endereos IP das estaes de origem A estao E1 deve encaminhar o datagrama para o roteador R1, cujo endereo IP Se o endereo fsico do roteador R1 no estiver na tabela ARP de E1, ela ativa o protocolo ARP para obter esse endereo, como no exemplo anterior de entrega direta.

Em seguida, o datagrama IP encapsulado no quadro da rede fsica onde est E1 e efetivamente transmitido. O quadro transporta os endereos fsicos da estao de origem E1 e do roteador R1. Aps receber o datagrama, o roteador pode entreg-lo estao de destino.

Por fim, o datagrama IP encapsulado no quadro da rede fsica onde est E4 e efetivamente transmitido. Nesse caso, o quadro transporta os endereos fsicos do roteador R1 e da estao de destino E4. Atividade: Usando simulador de rede Em preparao para a realizao desta atividade, voc deve instalar o software NetSimk para simulao de redes.

Para fazer o download do software NetSimk, siga os seguintes passos: 1. Abra o navegador do Linux Educacional; 2. Acesse o site: www. Clique em Download Netsimk; 4. Selecione o Desktop como destino do download; 5. Aps o download, feche o navegador, aponte para o cone do NetSimk e clique com o boto direito do mouse; 6.

Selecione a linha do Netsimk. Aps a extrao, clique duas vezes no cone do NetSimk para executar. Note que, apesar de ser um software desenvolvido para Windows, ele funciona perfeitamente sob o Linux Educacional, graas ao software wine j instalado.

A estao E1, ao enviar um pacote para a estao E2, por exemplo, far uma entrega direta, porque ambas esto na mesma rede; portanto, no ter a necessidade de entregar via roteador gateway padro. Por outro lado, ao enviar um pacote para a estao E4, por exemplo, ter que fazer uma entrega indireta via roteador, e este far a entrega direta do pacote estao E4. Siga o seguinte roteiro: 1.

Verifique se a tabela ARP da estao E1 est vazia, usando o comando arp -a. Na estao E1, execute o comando ping Verifique novamente a tabela ARP da estao E1.

Nesse caso, a estao E1 fez uma entrega direta. Nesse caso, a estao E1 fez uma entrega indireta. Por que podemos fazer esta afirmao? Soluo A estao E1, ao enviar um pacote para a estao E2, por exemplo, far uma entrega direta porque ambas esto na mesma rede, portanto, no ter necessidade de entregar via roteador gateway padro.

Por outro lado, ao enviar um pacote para a estao E4, por exemplo, ter que fazer uma entrega indireta via roteador e este far a entrega direta do pacote estao E4. Para exemplificar os mecanismos de entrega direta e indireta vamos usar o simulador Netsimk aplicado rede da figura anterior, conforme veremos a seguir.

Esse simulador pode ser obtido gratuitamente no endereo www. O simulador foi desenvolvido pelo Prof. Na estao E1, aps a execuo do comando ping Para constatar que foi realmente assim, alm da tabela ARP que mostra apenas o endereo MAC da estao E2, podemos verificar a atividade do roteador R1 que interliga as duas redes.

Nesse ponto a atividade do roteador R1 nula, porque a estao E1 fez uma entrega direta para a estao E2, sem passar pelo roteador R1.

Porm, aps a execuo do comando ping Reply from Note que agora aparece tambm o endereo IP e o endereo fsico da interface E0 do roteador R1, portanto, o roteador R1 participou do processo de entrega para a estao E4, conforme mostrado a seguir. Vamos fazer uma anlise passo a passo. Ela encaminha o pacote IP para o roteador R1, para que ele faa a entrega indireta.

Hello everyone, So I bought a laptop and I'm wondering if anyone in linux-land has tried to install any linux dirtro on these. May have to return it unless someone has an answer. But there is no literature on the web or any manuals for these laptops.

Any help is appreciated. I've got 60 days to return it and get my money back.. Last edited by Timothy Miller; at AM. Timothy Thanks for replying so quickly. It might be a good Saturday after all.. Well, I was under the impression that the latest distro's such as Ubuntu If I am wrong would you guide me to on compatible one please? A link perhaps.? Much appreciared I'd be very wary of that item. The only reviews I can see are customer ones at Amazon, which can be summed up as "you get what you pay for".

I can't find any report of some-one installing Linux on one. There's nothing worse than needing help for something that few people use and no-one seems to have documented! If you really need a cheap laptop, I'd go for a secondhand model, preferably from a firm that sells reconditioned, ex-corporate ones. Being unfamiliar with the make and model and internals. I thought it may be a arm cpu laptop.
