Lync online Bandwidth and Security• We don’t have to deploy Lync servers but:• Internet Bandwidth to Microsoft Data
Centers are important• Lync Online users use their managed
networks and Internet to connect to Microsoft datacenters.
• Network conditions are important for A/V sessions and Customer Experience
• Customer communication and traffic should be secure

Lync Online Audio / Video Quality of Experience
• Lync Online AV conference or peer to peer call
• Quality maybe choppy, tinny, or delayed and will result on meeting or call unusable
• Common reasons:• Poor network connectivity, Delay, Jitter, Packet Loss• Low-bandwidth network connections• Poor audio quality from a particular device

• A Lync BW Calculator for Lync Online will help to estimate Internet Bandwidth
• Lync BW calculator is for Lync On-prem• Can we adapt the calculator for Lync Online?• Lync Online Data Center = Central Site on Lync BW
calculator?• We need to consider if the customer has only one or
many Internet Access• Assume usage Model are the same

• Customer will know capacity and network conditions for Lync Online Best Experience
• Today we can leverage tools like Ixia to simulate, P2P traffic on customer Network
• We are working on Lync Online Conference Simulation (not available today) for Lync Online MT
• Other Traffic simulation tools can be used

Lync Online QoS

• Lync Online is at Microsoft Data Center and the customer use his network, Internet and Lync Online Data Center
• Jitter, Packet Loss and Latency also exist and have to be considered
• We can provide QoS for Lync Online on Managed networks not over Internet.
Latency, Packet Loss, Jitter

Lync Online and QoS
• Lync Online Media Port Changes Offer Better Bandwidth Management
• Lync Online media ports have been split into three separate categories, giving you much better control over network bandwidth
• Use Quality of Service (QoS) group policies to give a higher network priority to audio or video packets.
• Separate port ranges for application sharing and file transfer are planned for a future service update
• QoS group policies only work with client machines running Windows 7 or Windows 8
• QoS policies apply only to peer-to-peer Lync conversations on a network you control
