NCS5500 : Durée de vie d’un paquet(transit, Punt/Inject, chemin Ping)

Introduction

Ce document décrit le chemin emprunté par les paquets de requête d'écho/réponse d'écho ICMP dans la zone NCS55xx(Fretta).

Durée de vie d'un paquet dans ASIC de transfert

IRPP

Un paquet est reçu sur une interface et transmis à IRPP où les 128 premiers octets seront extraits et traités. Par conséquent, l'en-tête du système interne est préfixé.

ITM

Le paquet est stocké dans la mémoire DRAM/OCB

ITPP

Si nécessaire, réécrivez l'en-tête système (réplication multidiffusion, mise en miroir des ports, etc.)

Les paquets sont divisés en cellules et leur charge est équilibrée en fabric

ERPP

Les cellules sont reçues et réassemblées. Les 128 premiers octets sont extraits et appliquent tous les filtres de couche liaison, la liste de contrôle d’accès de sortie, la réplication de sortie (multidiffusion)

ETPP/ETM

Le paquet entier est stocké dans une mémoire tampon jusqu'à ce que le paquet sortant soit planifié. Les en-têtes système sont supprimés.

ASIC de transfert de pipeline

IRPP (Port Term, Analyseur)

Terminaison du port : Paquets reçus de l'interface réseau/CPU/Recirculation

• Déterminez le port source et marquez le paquet avec lui.
• Décidez du programme initial à utiliser dans l'analyseur.
• Identifiez le début de l’en-tête du réseau.

Analyseur : Extraire Ethertype, Adresses MAC, Déterminer le décalage pour les étapes suivantes du pipeline.

IRPP (couche de ligne, transbordement VLAN)

Couche liaison : Filtrage sur L2 et authentification d'adresse source.

Traduction VLAN : Nous mappons l'interface logique du paquet.

Chemin Punt

• Seules quelques entrées TCAM LPTS sont disponibles sur le NPU en raison d'un manque de ressources TCAM.
• La recherche LPTS majeure est effectuée dans SW LPTS Pre-IFIB sur LC Netio
• Paquet de pontage LPTS de NPU vers RP directement via la recherche TCAM PMF :
  • Les paquets OSPF, OSPFv3 mcast et ISIS sont acheminés directement vers le RP actif et de secours
• Paquet de pontage LPTS de NPU au CPU local via la recherche TCAM PMF :
  • Tout protocole qui utilise TCP, UDP ; ICMP, ND
• Les paquets de protocole de couche 2 sont punis à LC via le piège CPU BRCM :
  • ARP, RARP, CDP, LACP, LLDP, OAM de liaison Ethernet, MACSec
• Les paquets d'exception sont punis à LC via le déroutement du processeur BRCM.
  • TTL0, TTL1, MTU dépassé, paquets d’option

Chemin d'accès unique entre deux noeuds CPU

Chemin d'accès du processeur NPU au processeur RP

Les paquets RX Forus sont répliqués sur NPU. L'une est envoyée au RP actif et l'autre au RP de démarrage

Injection du processeur RP vers le processeur NPU ou LC

Les paquets de couche 3 sont injectés directement à NPU si la contiguïté de préfixe est terminée ou s’il s’agit d’un paquet de pré-route

Les paquets de couche 3 sont injectés au processeur LC dans le cas où :

• La contiguïté de préfixe est GLEAN.
• Paquet de pré-routage MPLS
• La taille du paquet dépasse la MTU.

Chemin d'injection du processeur LC vers NPU

Ces paquets sont injectés du CPU LC au NPU :

• ARP, ND, réponse écho ICMP, paquets fragmentés
• Paquets CDP, LACP, LLDP, OAM EtherLink

Ping distant

Chemin du paquet : Demande d'écho

Local Node[ICMP(RP) -> IP I/O(RP) -> NetIO/Forwarder(RP) -> SPP(RP) -> NPU] -> wire -> Remote[NPU -> LPTS(HW) -> SPP(LC) -> NetIO/Forwarder(LC) -> LPTS(SW)(LC) -> IP I/O (LC) -> ICMP (LC)]

Chemin du paquet : Réponse d'écho

Remote Node[IPv4/ICMP (LC) -> FWD/NetIO (LC) -> SPP (LC) -> NPU] -> wire -> Local Node[LPTS(HW) -> SPP(LC) -> NetIO/Forwarder(LC) -> NetIO(RP) -> IP I/O (RP) -> ICMP (RP)]

Ping local

Chemin du paquet : Demande d'écho

RP(ICMP/IPv4 IO -> netio -> SPP -> CE) -> LC(SPP -> netio -> ICMP/ipv4 IO)
