    簡介

    本文檔介紹如何在AWS環境中部署的Catalyst 8000V上啟用和利用多TXQ以提高吞吐量效能。

    背景資訊

    多個隊列的存在簡化並加速了將傳入和傳出資料包對映到特定vCPU的過程。在Catalyst 8000V上利用多TXQ可跨分配的可用資料平面核心實現有效的核心利用率，從而提高吞吐量效能。本文簡要概述多TXQ的工作原理、配置方式、顯示自治和SD-WAN Catalyst 8000V部署的CLI配置示例，並檢視故障排除命令以幫助發現效能瓶頸。

    Catalyst 8000V不使用多TxQs時的行為

    在17.18軟體發行版之前，進入Catalyst 8000V的資料包會被分配到所有vCPU（資料包處理核心），與資料流無關。PP完成資料包處理後，流順序將恢復為通過介面傳送。

    將封包放入傳輸佇列(TxQ)之前，Catalyst 8000V會為每個介面建立一個TxQ。因此，如果只有一個可用的輸出介面，則多個串流會進入一個TxQ。 

    如果只有一個可用的介面，Catalyst 8000V無法利用此多TxQ過程。這會導致吞吐量效能瓶頸和可用資料平面核心之間的負載分佈不均。如果只有一個輸出介面用於從C8000V例項傳輸資料，則只有一個TxQ可用於傳輸網路流量，並且可能導致資料包因單個隊列填充速度較快而丟棄。

    如需參考，您可以在圖1中找到在AWS中部署的Catalyst 8000V的單一TxQ架構模型。

    Process diagram

    圖 1:在AWS中部署的Catalyst 8000V的單一TxQ架構模型。

      1. 網路資料包(PKT)通過VPC並在C8000V的輸入介面上接收。
      2. PKT被置於接收隊列(RX)上，然後被轉發到由演算法決定的分組處理器(PP)引擎。
      3. 封包處理器(PP)處理封包後，會將封包傳送到流量管理員(TM)。
      4. 在TM處理結束時，一個核心負責將資料包放入一個可用TxQ中，然後將該TxQ轉發到Catalyst 8000V的出口介面。

    什麼是AWS基礎設施中的多業務交叉隊列

    AWS ENA提供多個傳輸隊列（多TxQ）以減少內部開銷並提高可擴充性。多個隊列的存在簡化並加速了將傳入和傳出資料包對映到特定vCPU的過程。AWS和DPDK網路參考模型基於流，其中每個vCPU處理一個流並將來自該流的資料包傳送到指定的傳輸隊列(TxQ)。每個vCPU的RX/TX隊列對基於流的模型是有效的。

    因為Catalyst 8000V不基於流，所以語句「每個vCPU的RX/TX隊列對」不適用於Catalyst 8000V。

    在這種情況下，RX/TX隊列不是每個vCPU，而是每個介面。RX/TX隊列充當應用程式(Catalyst 8000V)和AWS基礎設施/硬體之間的介面，用於傳送資料/網路流量。AWS控制每個介面在每個例項上可用的RX/TX隊列的數量和速度。

    Catalyst 8000V必須具有多個介面才能建立多個TxQ。為了保持流順序，使多個流從介面流出（在Catalyst 8000V啟用此流程後的多個TxQ後），Catalyst 8000V將基於5元組的流雜湊以選擇適當的TxQ。通過使用環回介面或輔助IP地址，使用者可以使用連線到例項的同一物理NIC在Catalyst 8000V上建立多個介面。

    在圖2中，您可以找到在AWS中使用帶Catalyst 8000V的多重TxQ架構處理資料包的方式。

    Process diagram

    圖2：在AWS中部署的Catalyst 8000V的多TxQ架構模型。

      1. 網路資料包(PKT)通過VPC並在C8000V的輸入介面上接收。
      2. PKT被置於接收隊列(RX)上，然後被轉發到由演算法決定的分組處理器(PP)引擎。
      3. 封包處理器(PP)處理封包後，會將封包傳送到流量管理員(TM)。
      4. 在TM處理結束時，在將資料包放入傳輸隊列(TxQ)之前，TM會檢視資料包報頭並對資料包進行雜湊（下一節將對此進行說明）。 另一個元件，即輪詢模式驅動程式(PMD)，用於配置例項支援的TXQ數量。一個核心專用於TM + PMD功能，該功能對分配的TxQ進行雜湊和資料包傳送。
      5. TxQ基於五個元組進行雜湊和模數提取，該元組具有例項支援的TxQ數。封包會被放置到選取的TxQ上，並轉送到Catalyst 8000V的出口介面。

    流量如何雜湊到多個TxQ

    如圖2的步驟4所示，在TM處理結束時，在將資料包放入TxQ之前，TM會檢視資料包報頭並提取5個元組（目的地址、源地址、協定、目標埠和源埠），然後將資料包雜湊到TxQ。

    TxQ基於五個元組進行雜湊和模數提取，該元組具有例項支援的TxQ數。

    支援多TxQs的Catalyst 8000V軟體版本

    相同例項系列型別的AWS EC2例項都支援不同數量的TXQ，具體取決於例項大小。C8000V開始支援從IOS® XE 17.7開始的多個TxQ。

    從IOS® XE 17.7開始，C8000V在C5n.9xlarge上支援多個TxQ ，最多可有8個TXQ。

    從IOS® XE 17.9開始，C8000V支援C5n.18xlarge例項大小，該大小最多可以有12個TXQ（比C5n.9xlarge多50%）。

    雖然IOS® XE 17.7支援多TxQ，但強烈建議使用IOS® XE 17.9來實現軟體生命週期和更高吞吐量效能以及12 TxQ支援。

    如何設計IP編址方案以計算雜湊

    若要在所有可用的TxQ之間均勻雜湊流量，在Catalyst 8000V終止IPsec/GRE通道時，需要使用特殊的IP位址。

    有公共指令碼可用於生成這些特殊的IP地址，用於配置負責終止這些隧道的Catalyst 8000V介面。本節提供有關如何下載和使用指令碼來設計即使多TxQ雜湊所需的IP地址的說明。

    如果Catalyst 8000V正在處理TCP/UDP等明文流量，則不需要特殊的IP編址方案。

    附註：對於運行17.18或更高版本的Catalyst 8000V，資料包的分配方式不同。因此，需要使用不同的雜湊演算法。

    另一個路由器端點(c8kv-peer)將應用類似的配置，其餘八個計算得到的雜湊IP地址(192.168.2.X)。

    Network connection

    圖5.使用輔助IP地址的十二個TxQ的拓撲示例。

    如果環回地址不能在AWS環境中使用，則可以改用連線到ENI的輔助IP地址。

    這是「c8kv-ut」的CLI配置示例（圖5），使用計算出的雜湊IP地址(10.0.2.X)建立12個IPsec隧道，源地址為1個主IP地址+連線到GigabitEthernet3介面的11個輔助IP地址。另一個路由器端點(c8kv-peer)上會套用類似的組態，餘下十二個已計算的雜湊IP位址(20.0.2.X)。 

    note-icon

    附註：在本示例中，我們使用第二個C8000V作為隧道端點，但也可以使用其他雲網路端點，如TGW或DX。

    AWS中的典型Catalyst 8000V部署

    自治模式

    請參閱先前的CLI配置和拓撲示例。可以根據網路編址方案和生成的雜湊IP地址來複製和修改CLI配置。

    要成功建立隧道，請務必在C8000V和AWS VPC的路由表中建立IP路由。

    SD-WAN模式

    這是一個拓撲和SD-WAN配置示例，它使用位於AWS VPC中的C8000Vs上的環回介面建立TLOC。

    Network connection

    圖6.在AWS VPC中的C8000Vs上使用帶環回介面的TLOC的SD-WAN拓撲示例。

    note-icon

    附註：在圖6中，黑色連線表示SD-WAN控制平面元素和SD-WAN邊緣裝置之間的控制(VPN0)連線。藍色連線表示使用TLOC的兩個SD-WAN邊緣裝置之間的隧道。

    您可以找到圖6的SD-WAN CLI配置示例（此處）。

    AWS中的吞吐量效能故障排除

    note-icon

    附註：在公共雲環境中執行效能測試引入可能會影響吞吐量效能的新變數。在執行此類測試時，需要考慮以下幾點：

    • 對等體在運行測試時的基礎資源使用情況
    • 不使用專用主機（使用專用主機將雲成本提高16倍）
    • 雲在不同地區運行，效能可能有所不同
    • 在某些情況下，無論特徵輪廓如何，數字都是相似的；這可能是由於AWS限制介面每例項大小
    • AWS在EC2例項上限制每秒資料包速率，這同樣會導致資料包丟棄
    • AWS不披露限制速率，但由於pps限制而丟棄的資料可通過「pps_allowance_exceeded」計數器進行觀察

    實用的CLI故障排除命令

    進行吞吐量效能測試時，可以使用這些故障排除命令來查明效能下降的瓶頸或原因。


    「show platform hardware qfp active statistics drop」 — 允許我們瞭解c8kv上是否有任何丟包。我們需要確保沒有顯著的尾部丟棄或任何相關的計數器增加。

    "show platform hardware qfp active statistics drop clear" — 此命令清除計數器。


    "show platform hardware qfp active datapath infrastructure sw-cio" — 此命令向我們詳細說明了效能運行期間資料包處理器(PP)、流量管理器(TM)的利用率情況。這使我們能夠從c8kv確定是否有足夠的處理能力。

    "show platform hardware qfp active datapath util summary" — 此命令提供從所有埠傳送/接收c8kv的輸入/輸出的完整資訊。

    確保檢查輸入/輸出速率並檢視是否有任何丟棄。此外，請確保檢查處理負載百分比。如果達到100%;這意味著c8kv已達到其容量。

    "show platt hardware qfp active infrastructure bqs interface GigabitEthernetX" — 此命令允許我們檢查介面層級統計資料，以瞭解佇列編號、頻寬、尾部捨棄。

    "show controller" — 此指令提供有關rx/tx正常封包、遺失封包的詳細資訊。

    此命令可用於我們看不到任何尾部丟棄，但流量生成器仍顯示丟棄的情形。

    在資料利用率已達到100%,PP也達到100%的情況下，可能發生這種情況。

    如果rx_missed_errors計數器持續增加，則意味著CSR對雲基礎設施進行反向壓力，因為它無法處理任何其他流量。

    「show platform hardware qfp active datapath infrastructure sw-hqf」 — 可用於檢查是否因AWS的背壓而發生擁塞。

    「show platt hardware qfp active datapath infrastructure sw-nic」 — 確定如何在多個隊列之間對流量進行負載均衡。17.7之後，我們有8個多TXQ。

    此外，它還可以確定是否有任何特定隊列正在接收所有流量或正正確進行負載均衡。

    "顯示控制器 |in errors|exceeded|Giga" — 顯示由於AWS端的pps限制而丟棄的資料包，可通過pps_allowance_exceeded計數器觀察此情況。

    CLI輸出示例

    尾部丟棄計數器不斷遞增的輸出示例 — 多次發出命令以檢視計數器是否遞增，從而讓我們確認計數器確實是尾部丟棄。
