© Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Bandwidth planning methods
5/16/2018 8:54 AM Bandwidth planning methods Know the network bandwidth utilization / headroom Monitor bandwidth utilization during a pilot Avoid shared bandwidth network providers Calculate a per user bandwidth with spreadsheets Limit OneDrive sync bandwidth per client Use a standard per user bandwidth amount MSIT publish the Microsoft one, Gartner have one Use flexible network providers and increase as needed © Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Other factors to consider
5/16/2018 8:54 AM Other factors to consider Exchange Use the on-premises baseline Consider SMTP to on-premises needs (or direct MX to Microsoft) Use after hours migration to test mailbox migration bandwidth Azure AD connectivity is minimal Use Outlook 2013 SP1 or later for performance improvement Skype Media across the perimeter only IM is bursty, latency tolerant, and very small Voice uses RTAudio (50kbps low, 80kbps high, auto-determination) Video depends upon resolution (280kbps low, 4000kbps high, dependent upon resolution) Desktop sharing depends upon desktop resolution Consider Peer-to-Peer (inside WAN) versus Client-Server (across perimeter) SharePoint HTTPS views of webpages, uploads/downloads of content Document editing with Office Web Apps or Office Bursty, but latency tolerant Requires baseline to estimate Will ramp up as more content is loaded into SharePoint, MySites, OneDrive for Business © Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Choosing a bandwidth planning method
5/16/2018 8:54 AM Choosing a bandwidth planning method Know the network bandwidth utilization / headroom Measure from routers, SNMP, IPFIX, client log tools Monitor regularly for all your network segments Keep records Monitor bandwidth utilization during a pilot Monitor the change for your pilot users Calculate Office 365 bandwidth per user Scale up to each network segment user population © Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Hints on bandwidth planning
5/16/2018 8:54 AM Hints on bandwidth planning Calculate a per user bandwidth with spreadsheets Spreadsheet calculators for Skype and Exchange Ask questions to help you identify usage Limit OneDrive sync bandwidth per client Opposite to calculators GPO deploy the limit Use a standard per user bandwidth amount MSIT publish the Microsoft one (400kbps for all network connectivity and not just Office 365) Gartner have one (Gartner consult required) Use flexible network providers and increase as needed Start small and expand BW when headroom gets low © Microsoft Corporation. All rights reserved. MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

Headroom management is important
5/16/2018 8:54 AM Headroom management is important Headroom is the percentage of free bandwidth on a circuit 0% (or not measuring) means you will have congestion, errors and retransmissions which increases latency 20% is minimal to avoid congestion 33% is common 50% is conservative, or is used for high availability across two geographically dispersed circuits. If one fails, the other can handle the whole load short term © Microsoft Corporation. All rights reserved.

Proxied Connection - Pros
5/16/2018 8:54 AM Proxied Connection - Pros Easy to Configure to get Office 365 connected Often existing internet access method Small Number of IP addresses for clients to direct traffic to Uses known ports for easy firewall traversal No need to route external IP address on internal network No requirement for external DNS resolution for clients Logical barrier between clients and the internet Management can be offloaded to partner (e.g. a Cloud Proxy vendor) Easy monitoring/auditing © Microsoft Corporation.

Proxied Connection - Cons
5/16/2018 Proxied Connection - Cons Often don’t scale to meet new demand without costly upgrades Often were not installed/designed with SaaS services in mind Older proxies often struggle to deal with the long lived, high throughput connections SaaS services entail Older Proxies generally are not designed/configured to handle UDP traffic Skype traffic is therefore forced over TCP in these cases Skype’s coping mechanisms for poor networks are drastically reduced when TCP is used Can delay frames on their way through adding jitter and latency Proxies commonly alter TCP level settings which can cause performance issues End result is often poor quality calls and performance © 2015 Microsoft Corporation.

5/16/2018 8:54 AM Advice for Proxy use Ensure the devices are scaled up to cope with SaaS services, both in terms of processing and NAT capability Avoid centralized proxies which can increase latency Ensure they are in the local region of the client (as a minimum) Evaluate Cloud Proxy nodes or those optimized for SAAS services Avoid using Skype for Business through these devices even when optimized Avoid unnecessary Packet inspection Ensure all settings are checked and optimized Look at whether offloading key Office endpoints is possible © Microsoft Corporation.

Direct Connection - Pros
5/16/2018 Direct Connection - Pros Allows direct UDP traffic so Skype can work at it’s best Generally no interference with payload at egress meaning optimal connectivity for all services Allows for local egress use in most cases meaning minimal latency Preferred connection method to Office 365 for most customers when ISP routing is optimal © 2015 Microsoft Corporation.

Direct Connection – Cons
5/16/2018 Direct Connection – Cons Customers need to authorize Office 365 URLs/IPs and open required ports on all firewalls used (if controlled egress is desired) These need to be constantly monitored and firewalls updated with changes which can be challenge in large organizations Missing updates to IP ranges can cause connectivity issues Routing to the appropriate egress needs to be managed internally External DNS required for clients Devices need to scale to the increased connection count needed for Office 365 services © 2015 Microsoft Corporation.

ExpressRoute - Cons Reliable internet connectivity is still required
5/16/2018 8:54 AM ExpressRoute - Cons Reliable internet connectivity is still required A good internet connection may give similar or better performance Often encourages hub and spoke model which may actually increase latency when compared to direct connection Higher cost of implementation, usage and maintenance Typically two to six months of planning required for implementation Highly skilled network team required Very high risk of connectivity problems on cutover if planning and maintenance is not done (e.g. asymmetric routes) Security still needs to be applied to the circuit Cost benefit ratio should be assessed and benefits fully understood © Microsoft Corporation.
