Slack 微型會議的網路與系統設定指南
透過微型會議 ,你的團隊可以直接在 Slack 工作空間或 Enterprise Grid 組織中進行即時語音或視訊對話。網路、系統或 IT 管理員可以參考本指南的檢查清單,確保網路和系統在團隊開始使用微型會議功能前已妥善設定,或在收到微型會議問題報告時進行疑難排解。
注意: 如果未遵守這些準則,我們無法保證微型會議可達到最佳效能,而且可能會導致我們無法有效幫助解決連線或效能問題。
微型會議網路路徑
核准 *.chime.aws 或 IP 範圍 99.77.128.0/18
允許往來 UDP/22466 和 TCP/443 的流量
網路設定
將微型會議網路路徑解除封鎖 如果封鎖任何必要的網路路徑,都會導致連線失敗或效能大幅下降。允許流量經由網路路徑傳輸,到達所有相關網路層 (防火牆、Proxy、VPN 和 Wi-Fi 網路)。
優先處理即時微型會議流量 即時語言、視訊和螢幕共享容易受到網路壅塞和頻寬限制的影響。如需制定服務品質政策,請確保政策規則要求優先處理微型會議網路路徑的流量 (或至少不會降低優先等級)。
允許微型會議流量略過 VPN VPN 通常會造成延遲、封包遺失和時基誤差,導致視訊微型會議體驗不佳。允許微型會議網路路徑的流量略過 VPN、用戶端和篩選工具,或設定分割隧道以允許直接轉送即時流量。如需設定分割隧道的詳細資訊,請聯絡 VPN 供應商。
允許微型會議流量略過 Proxy Proxy 會導致即時效能降低,還可能會造成微型會議功能意外失效。允許所有微型會議網路路徑的流量略過 Proxy,並停止在收到微型會議相關請求時重寫網址,以將延遲降到最低,並確保可以正常連線。
停用封包檢查和篩選功能 深度封包檢查或篩選功能可能會中斷即時媒體串流,造成微型會議期間出現延遲和連線問題。停用微型會議網路路徑流量的所有封包檢查和篩選功能。
將 VDI 環境微型會議設定最佳化 (建議) 由於額外的延遲和連線問題,虛擬桌面基礎架構 (VDI) 環境中的即時效能通常較差。我們不建議在 VDI 中使用微型會議功能,但如果你的團隊需要這樣做,可以切換到純語音模式,以盡量減少資源消耗並改善效能。你也可以詢問 VDI 供應商是否提供可安裝在使用者電腦上的企業級安全瀏覽器 (因為這類瀏覽器通常會略過 VDI 相關轉送,並將運算密集的語音和視訊處理工作卸載到本機裝置)。
系統設定
確定授予了媒體裝置存取權 為了能正常運作,微型會議需要存取使用者的麥克風、攝影機和喇叭,而且需要啟用螢幕錄製權限。確定所有使用者都能讓 Slack 從裝置存取這些工具後,請檢查使用的第三方安全性或隱私權工具是否會阻擋或干擾媒體裝置存取或以 USB 連接的媒體裝置。
啟用硬體加速 硬體加速可確保有效率地處理視訊和螢幕共享串流,並降低 CPU 使用量。為了維持高品質的微型會議體驗,請確認所有使用者的 Slack 應用程式和獲准的瀏覽器都已啟用硬體加速。
支援視訊轉碼器 微型會議仰賴 AV1、VP9 和 H.264 進行媒體編碼和解碼。為了確保轉碼過程達到最佳效果,請定期更新使用者的裝置和顯示卡驅動程式。
自動更新前退出 Slack 如果 Slack 在舊版本仍在執行時進行部分更新,Slack 的許多功能 (包括裝置存取和語音播放) 可能會中斷。如果為使用者執行自動更新,請將所有軟體的更新自動化工具和流程設為在啟動更新前完全退出 Slack (或避免自動更新在使用者退出 Slack 之前套用)。
將裝置設為高效能模式 (建議) 省電設定可能會限制使用 CPU 或 GPU,導致系統效能降低,進而影響微型會議期間的即時語音和視訊品質。我們建議確保使用者的裝置都設為高效能模式,並停用所有在裝置未連接電源時會導致網路或處理效能降低的設定。
