Abstract

"DISPOSITIVOS DE ROTEAMENTO E DE Nó". A invenção se refere a um dispositivo de roteamento para roteamento correntes em um nó em uma rede de transmissão de pacote, sendo que cada corrente é transmitida com parâmetros especificados para sua perda e retardo na rede, o dispositivo de roteamento compreendendo: conjunto de circuitos de controle de admissão de corrente para recepção de uma requisição de corrente e para leitura: (i) os ditos parâmetros especificados e quaisquer valores para perda e retardo já incorridos em nos precedentes na rede, ou (ii) os ditos parâmetros especificados, quando modificados para levar em conta perda e retardo já incorridos em nós precedentes na rede, para determinar, em conjunção com correntes existentes já sendo manipuladas pelo dispositivo de roteamento, se aceita ou rejeita a corrente; conjunto de circuitos de memória intermediária incluindo uma pluralidade de memórias intermediárias, sendo que uma ou mais das ditas memórias intermediárias são alocadas à dita corrente, se a solicitação de corrente foi aceita; e dispositivos para transmissão (i) a requisição de corrente com valores modificados para perda e retardo, ou (ii) a requisição de corrente com parâmetros modificados para levar em conta a perda e retardo incorridos neste e nos nós precedentes na rede, se a solicitação de corrente foi aceita, e para retorno de um sinal de falha, se a requisição de corrente foi rejeitada.
