alternância de pacotes

packet switching

Tecnologia para quebrar dados em pacotes e enviar esses pacotes através de uma rede. Todo pacote possui um cabeçalho com sua origem e destino, um número seqüencial para remontar as informações, um bloco de conteúdos de dados e um código de verificação de erro. Os pacotes de dados podem adotar rotas diferentes para seus destinos, onde as informações originais são remontadas depois da chegada deles. O padrão internacional para redes de alternância de pacotes é X.25.
