預估網路頻寬需求Estimate network bandwidth requirements

使用 Office 365 可能會增加貴組織的網際網路電路使用量。Using Office 365 may increase the utilization of your organization's internet circuit. 請務必確定目前的頻寬是否足以負荷 Office 365 完整部署後的估計增加量,並且至少預留 20% 的頻寬,以因應極度忙碌時期。It's important to determine if the amount of bandwidth currently available is enough to handle the estimated increase once Office 365 is fully deployed while leaving at least 20% capacity to handle the busiest of days.

若要估計頻寬,請依照下列步驟操作︰To estimate the bandwidth, use the following steps:

  1. 評估會使用每個網際網路出口的用戶端數量。Assess the number of clients that will use each Internet egress. 盡可能地讓我們的多兆位元網路處理連線。Let our multi-terabit network handle as much of the connection as possible.

  2. 決定哪些 Office 365 服務與功能可供用戶端使用。Determine which Office 365 services and features will be available for clients to use. 您可能需要一組人員搭配不同的服務或使用設定檔。You will likely have groups of people with different services or usage profiles.

  3. 針對由用戶端組成的試驗群組測量網路使用狀況。Measure the network use for a pilot group of clients. 請確保試驗用戶端能代表組織中屬於各種不同設定檔及地理位置的人員。Ensure the pilot clients are representative of the different profiles of people in the organization as well as the different geographic locations. 您可以對照 ExchangeMicrosoft 小組 舊的計算機,或是我們在自己網路上所執行的 案例研究 ,來交叉檢查您的結果。You can cross-check your results against our old calculators for Exchange and Microsoft Teams or the case study we performed on our own network.

  4. 從試驗群組的測量結果推算整個組織的需求,然後重新測試以驗證估計值,再變更您的網路設定。Use the measurements from the pilot group to extrapolate the entire organization's needs and re-test to validate the estimations before making any changes to your network.

測試您現有的網路Test your existing network

網路工具:Network tools. 測試及驗證您的網際網路頻寬,以判斷下載、上傳和延遲限制。Test and validate your Internet bandwidth to determine download, upload, and latency constraints. 這些工具會協助您確定用於移轉及完整部署後的網路能力。These tools will help you determine the capabilities of your network for migration as well as after you're fully deployed.

Office 365 的網路規劃和移轉效能改善最佳作法Best practices for network planning and improving migration performance for Office 365

如需改善 Office 365 體驗的詳細資訊,請進一步閱讀這些最佳做法。Dig a little deeper into these best practices for more information about improving your Office 365 experience.

  1. 您想立即開始協助您的使用者嗎?Want to get started helping your users right away? 如果您在使用包含 SharePoint Online、Exchange Online 和 Lync Online 等 Office 365 產品時網路運作不順暢,請參閱在網路緩慢的情況下使用 Office 365 的最佳做法See Best practices for using Office 365 on a slow network for tips on using Office 365, including SharePoint Online, Exchange Online, and Lync Online, when your network just isn't cooperating. 本文含有大量 TechNet 及 Support.office.com 的連結,內容介紹如何最佳化您的 Office 365 體驗,並包含輕鬆自訂網頁的方法,以及如何設定 Internet Explorer 以享受最佳 Office 365 體驗等資訊。This article links out to loads of content on TechNet and Support.office.com for optimizing your Office 365 experience and includes information on easy ways to customize your web pages and how to set your Internet Explorer settings for the best Office 365 experience.

  2. 請閱讀 Office 365 網路連線原則,了解安全管理 Office 365 流量以及可能獲取最佳效能的連線原則。Read Office 365 Network Connectivity Principles to understand the connectivity principles for securely managing Office 365 traffic and getting the best possible performance. 本文將協助您了解以安全方式最佳化 Office 365 的網路連線能力的最新指引。This article will help you understand the most recent guidance for securely optimizing Office 365 network connectivity.

  3. 謹慎管理 Windows Updates 排程來改善郵件移轉效能。Improve mail migration performance by carefully managing the schedule for Windows Updates. 您可以批次更新用戶端電腦,確定所有用戶端電腦已在移轉至 Office 365 前更新,以管制網路頻寬的使用。You can update your client computers in batches and ensure that all client computers are updated before migrating to Office 365 to regulate the use of network bandwidth. 如需詳細資訊,請參閱針對 Office 365 手動更新及設定電腦以取得最新更新For more information, see Manually update and configure desktops for Office 365 for the latest updates.

  4. 有些組織將 Office 365 放置在不受信任網際網路服務的網路流量上,然而,Office 365 網路流量在被視為受信任的網際網路服務而允許略過大部分的篩選和掃描時可以達到最佳效能。Office 365 network traffic performs best when it's treated as a trusted Internet service and allowed to bypass much of the traditional filtering and scanning that some organizations place on network traffic to untrusted Internet services. 這通常包括移除如 Proxy 使用者驗證和封包檢查等輸出處理,以及確保本機出口至網際網路使用正確的網路位址轉譯 (NAT) 和擁有足夠的頻寬能力可以處理增加的網路需求。This typically includes removing outbound processing such as proxy user authentication and packet inspection, as well as ensuring local egress to the Internet with the proper Network Address Translation (NAT) and enough bandwidth capacity to handle the increased network requests. 如需有關設定您的網路,將您網路中的 Office 365 視為受信任網際網路服務進行處理的其他指引,請參閱管理 Office 365 端點Refer to Managing Office 365 endpointsfor additional guidance on configuring your network to handle Office 365 as a trusted Internet service on your network.

  5. 務必閱讀管理 Office 365 端點Ensure Managing Office 365 endpoints. 移往 Office 365 的其他流量會導致輸出 Proxy 連線的增加以及 TLS/SSL 安全流量的增加。The additional traffic going to Office 365 results in an increase of outbound proxy connections as well as an increase in secure traffic over TLS/SSL.

  6. 如果您的輸出 Proxy 需要使用者驗證,您可能會遇到連線速度緩慢或喪失連線能力的狀況。If your outbound proxies require user authentication you may experience slow connectivity or a loss of functionality. 略過 Office 365 網域的驗證需求可以減少這項負擔。Bypassing the authentication requirement for the Office 365 domains can reduce this overhead.

  7. 如果您有大量的共用行事曆和信箱,可能會看見從 Outlook 至 Exchange 的連線數目增加。If you have a large number of shared calendars and mailboxes, you may see an increase in the number of connections from Outlook to Exchange. 例如,Outlook 用戶端可能會針對每個使用中的共用行事曆,開啟最多兩個額外連線。For instance, the Outlook client may open up to two additional connections for each shared calendar in use. 在此情況下,請確定出口 Proxy 可以處理連線,或針對 Outlook 對 Office 365 的連線來略過 Proxy。In this situation, ensure that the egress proxy can handle the connections, or bypass the proxy for connections to Office 365 for Outlook.

  8. 決定公用 IP 位址的支援裝置數目上限,以及如何平衡多個 IP 位址的負載。Determine the maximum number of supported devices for a public IP address and how to load balance across multiple IP addresses. 如需詳細資訊,請參閱 Office 365 的 NAT 支援For more information, see NAT support with Office 365.

  9. 如果您正在檢查您網路上電腦的輸出連線,針對 Office 365 網域略過此篩選可以改善連線能力及效能。If you're inspecting outbound connections from computers on your network, bypassing this filtering to the Office 365 domains will improve connectivity and performance. 此外,略過輸出檢查通常不需要單一網際網路出口,而且會啟用 Office 365 的本機網際網路出口目的地為網路的需求。Additionally, bypassing outbound inspection often removes the need for a single Internet egress and enables local Internet egress for Office 365 destined network requests.

  10. 有些客戶會發現內部網路設定可能會影響效能。Some customers find internal network settings may affect performance. 如傳輸單元最大值 (MTU) 的大小、網路自動交涉或自動偵測以及網際網路的次佳路由等設定都是要經常查看的地方。Settings such as maximum transmission unit (MTU) size, network auto-negotiation or auto-detection, and sub-optimal routes to the Internet are common places to look.
