Abstract

esquema de recuperação do caminho compartilhado uma rede de conexão orientada (6) tem um primeiro de trabalho (w1) e um segundo caminho de trabalho (w2). um nó (e) recebe sinalização para alocar recursos para uma parte de um caminho recuperado (r1) para o primeiro caminho trabalho (w1). os recursos são compartilhados pelo caminho recuperado (r1) para o caminho de trabalho e um caminho recuperado (r2a) para o segundo caminho de trabalho (w2). o nó (e) armazena uma associação entre os recursos compartilhados e um nó (a) no primeiro caminho de trabalho , identificados na sinalização , que deve ser notificado quando os recursos compartilhados são usados pelo caminho recurperado (r2a)para o segundo caminho de trabalho (w2). um objetivo rsvp-te na sinalização transporta um endereço do nó a ser notificado. o nó (e) envia uma mensagem de notificação rsvp-te a um nó (a) no primeiro caminho de trabalho (w1) que indica que os recursos compartilhados estão em uso.
