NCS5500:封包的壽命（傳輸、點選/注入、Ping路徑）

簡介

本檔案將說明NCS55xx(Fretta)方框中的ICMP回應請求/回應回覆封包所採用的路徑。

資料包在轉發ASIC中的壽命

IRPP

在介面上接收資料包，並將其傳遞到IRPP，在此提取和處理前128個位元組。因此，內部系統報頭會預先加好。

ITM

資料包儲存在DRAM/OCB中

ITPP

如果需要，請重寫系統報頭（組播複製、埠映象等）

資料包被拆分為信元並負載均衡到交換矩陣

ERPP

接收並重組信元。提取前128位元組，並套用所有連結層過濾器、輸出ACL、輸出複製（多點傳送）

ETPP/ETM

整個資料包將儲存在緩衝區中，直到計畫出資料包。系統標頭被移除。

管道轉發ASIC

IRPP（埠術語、解析器）

埠終止：從網路介面/CPU/Recycle收到的資料包

• 確定來源連線埠並標籤封包。
• 決定要在分析器中使用的初始程式。
• 確定網路報頭的起始位置。

分析器：提取Ethertype、MAC地址、確定管道中下一階段的偏移量。

IRPP（線路層，VLAN傳輸）

鏈路層：對L2和源地址身份驗證進行過濾。

VLAN轉換：我們對映資料包的邏輯介面。

點線路徑

• 由於TCAM資源不足，NPU上只有幾個LPTS TCAM條目可用。
• 主要LPTS查詢在LC Netio上的SW LPTS Pre-IFIB中完成
• LPTS直接通過PMF TCAM查詢將資料包從NPU傳送到RP:
  • OSPF、OSPFv3廣播、ISIS資料包直接轉發到主用和備用RP
• 通過PMF TCAM查詢將資料包從NPU傳送到本地CPU:
  • 任何使用TCP、UDP的通訊協定；ICMP、ND
• 透過BRCM CPU陷阱將L2通訊協定封包傳送到LC:
  • ARP、RARP、CDP、LACP、LLDP、以太鏈路OAM、MACSec
• 異常資料包通過BRCM CPU陷阱傳送到LC。
  • TTL0、TTL1、MTU Exceed、選項資料包

兩個CPU節點之間的分支路徑

從NPU到RP CPU的列印路徑

RX Forus資料包在NPU上複製。一個被傳送到活動RP，另一個被傳送到站點RP

從RP CPU注射到NPU或LC CPU

如果字首鄰接關係完成或它是預路由資料包，則直接將第3層資料包注入到NPU

在下列情況下，第3層封包會被注入到LC CPU:

• 字首鄰接為GLEN。
• MPLS路由前資料包
• 封包大小超過MTU。

從LC CPU向NPU插入路徑

從LC CPU向NPU注入以下資料包：

• ARP、ND、ICMP回應回覆、分段資料包
• CDP、LACP、LLDP、以太鏈路OAM資料包

遠端Ping

封包路徑：回應請求

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)]

封包路徑：回應回覆

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)]

本地Ping

封包路徑：回應請求

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

封包路徑：回應回覆

LC(IPv4 IO/ICMP -> Netio -> SPP -> CE) -> RP(SPP -> net -> ipv4 io/ICMP)
