Office 365 optimization 编辑

The Office 365 Optimization features adhere to the Microsoft Office 365 Network Connectivity Principles, to optimize Office 365. Office 365 is provided as a service through several service endpoints (front doors) located globally. To achieve optimal user experience for Office 365 traffic, Microsoft recommends redirecting Office365 traffic directly to the Internet from branch environments. Avoid practices such as backhauling to a central proxy. Office 365 traffic such as Outlook, Word are sensitive to latency and backhauling traffic introduces more latency resulting in poor user experience. Citrix SD-WAN allows you to configure policies to break out Office 365 traffic to the Internet.

The Office 365 traffic is directed to the nearest Office 365 service endpoint, which exists at the edges of Microsoft Office 365 infrastructure worldwide. Once traffic reaches a front door, it goes over Microsoft’s network and reaches the actual destination. It minimizes latency as the round trip time from the customer network to the Office 365 endpoint reduces.

Office 365 endpoints

Office 365 endpoints are a set of network addresses and subnets. Office 365 endpoints are classified into Optimize, Allow, and Default categories. Citrix SD-WAN 11.4.0 provides a more granular classification of the Optimize and Allow categories, enabling selective bookending to improve the performance of network-sensitive Office 365 traffic. Directing network-sensitive traffic to SD-WAN in the cloud (Cloud Direct or an SD-WAN VPX on Azure), or from an at-home SD-WAN device to an SD-WAN at a nearby location with more reliable Internet connectivity, enables QoS and superior connection resilience compared to simply steering the traffic to the nearest Office 365 front door, at the cost of an increase in latency. A bookended SD-WAN solution with QoS reduces VoIP dropouts and disconnects, reduces jitter and improves media-quality mean opinion scores for Microsoft Teams:

• Optimize - These endpoints provide connectivity to every Office 365 service and feature, and are sensitive to availability, performance, and latency. It represents over 75% of Office 365 bandwidth, connections, and volume of data. All the Optimize endpoints are hosted in Microsoft data centers. Service requests to these endpoints must breakout from the branch to the Internet and must not go through the data center.

The Optimize category is classified into the following subcategories:

- Teams Realtime
- Exchange Online 
- SharePoint Optimize
