Este documento descreve o caminho seguido pelos pacotes ICMP echo request/Echo Reply dentro da caixa NCS55xx(Fretta).
IRPP
Um pacote é recebido em uma interface e transmitido ao IRPP, onde os primeiros 128 bytes serão extraídos e processados. Como resultado, o cabeçalho interno do sistema é precedido.
ITM
O pacote é armazenado na DRAM/OCB
ITPP
Se necessário, reescreva o cabeçalho do sistema (replicação multicast, espelhamento de portas, etc.)
Os pacotes são divididos em células e balanceados para a estrutura
ERPP
As células são recebidas e remontadas. Os primeiros 128 bytes são extraídos e aplicam todos os filtros da camada de enlace, ACL de saída, Replicação de saída (Multicast)
ETPP/ETM
O pacote inteiro é armazenado em um buffer até que o pacote de saída seja programado. Os cabeçalhos do sistema são removidos.
Terminação de porta: Pacotes recebidos da interface de rede/CPU/reciclagem
Analisador: Extraia Ethertype, MAC Addresses, Determine o deslocamento para os próximos estágios no pipeline.
IRPP(Line Layer, VLAN Trans)
Camada de enlace: Filtragem em L2 e autenticação de endereço de origem.
Tradução de VLAN: Mapeamos a interface lógica do pacote.
Os pacotes RX Forus são replicados na NPU. Um é enviado para o RP ativo e outro para o RP standby
Os pacotes L3 são injetados diretamente na NPU se a adjacência de prefixo estiver completa ou se for um pacote de pré-roteamento
Os pacotes L3 são injetados na CPU do LC no caso:
Estes pacotes são injetados da CPU LC para a NPU:
