Recommendations
Back office Workers
Typically work from the office
IM and voice
Primarily internal communication
Sales representatives
Often work from outside the office
IM, Voice, Conferencing
Many interactions with customers (lots of PSTN calls)
Used as the baseline for the traffic simulation
For example, > 20% talk time in typical enterprise environment is unrealistic.
Trending towards an IM and video world and not and email and voice world

Usage models define how much users are communicating using a specific modality
Personas define groups of users with common communication characteristics and work habits
Sites, links, and users are customer data taken straight from the Data Discovery phase of the network
assessment
Another round of calculations and analysis might be needed
Helps you to become a trusted advisor
Default values (start with these)
Typical as seen in modern enterprise deployments
Adjustments based on organization’s policies (restrict or encourage certain communications
methods)
Utilization of Lync modalities as defined in usage models: none, low, medium, high
Can be job-related (for example, ”our sales reps make plenty of PSTN voice calls”).
Can be related to administrative policy (for example, “video calls are not allowed for vendors in our
organization”).
Percentage of users working remotely: 0% – 100%
Others factors related to administrative policies or users behavior
How do people work in the organization as of today?
What groups of people can be identified?
What are work habits in these groups?
Are meetings a common way of working?
Is it common for employees to work remotely?
Medium works in most typical scenarios
Change to Low or High if you have specific guideline from the customer
Changing to None has much bigger impact
None is always 0%
Modality
IM/P
Impact
Is it really a RTC ?
*
No
Audio
Yes
Video
Yes
App/Desktop Sharing
No
Central sites
Branch sites
Total size of WAN link
Amount of WAN link that might be used by Lync RTC
So what is the RTC? Does the customer have QoS classes?
Industry standard – 30%
Internet links (if applicable)
Total user population is not enough
How many employees and how do they work?
Refer to ”Usage models” and ”Personas”
Visitors add to the traffic requirements
