Transcript Network Assessment Overview

A service offering that provides an application-centric assessment that pinpoints problems that
could affect your future Microsoft Unified Communications solution
Discovery Session
Usage Modelling
Traffic Simulation
Understand what
network environment
exists
Model proposed
bandwidth using user
profiles, and usage
patterns
Using a UC Traffic
simulator apply real
traffic to production
network and monitor
factors that affect the
quality of UC traffic,
Delay, Jitter, and
Packet Loss
Recommendations
Analyze factors
affecting quality and
produce a full report
with
recommendations
Network
Impact
• How does real-time communication affect your
network?
• How does your network impact real-time
communication?
User
Experience
• Network as a fundamental of success
• Even a perfect Lync deployment can fail because
of network
• “The technology is only as good as the last call”
Proactive
Reactive
• What are your plans on Voice and Video?
• Is your network ready for Real-Time Communications\Unified
Communications (RTC\UC)?
• Have you considered RTC\UC when planning and building your network?
• What are your expectations on usage?
• Is your customer having quality issues?
Proactive
Approach
Early Discovery
Assess Readiness
Layer 7 Analysis
Recommendations
on Lync
Deployment
Measure Actual
Performance
Validates an
Enterprise’s Readiness
for RTC
Highlights areas that
might impact RTC
readiness
Quantitative
assessment of current
Infrastructure metrics
that impact RTC
Reduces deployment
risk
Protects customer’s
investment in RTC
Promotes the best
possible end user
experience
Should be part of every Enterprise Voice deployment
Large percentage of voice support calls attributed to
network impairments
Can be conducted when
Lync is introduced
New workloads are introduced
New user populations are enabled for Lync
QoS is being introduced/adopted

Concerns
These are business opportunities for Partners
Poor end user UC
experience
High number of help
desk tickets
Frustration: Poor
perception of the
products ability
Saturated networks
can affect other line of
business (LOB)
applications
Poor return on
investment (ROI) on
UC investment
Reduced productivity
and collaboration

Recommendations
Gain a full understanding of all aspects of the network infrastructure, the existing telephony
infrastructure, conferencing infrastructure, and details of the planned unified communications
application deployment
Uncover current or future topologies
Confirm Simulation Probe placement choice
Ensure information is collected for calibration of Usage Models
To properly estimate the amount of bandwidth Lync might consume on the customers network
Define the personas
Define usage models
Provide a basis for the traffic simulation phase
Identify areas of the network infrastructure that could cause a sub-optimal user experience for the Lync
application
Uncover current or future potential sources of network impairments
Place real traffic on the network to observe how it really operates
Correlate the information obtained from the previous three phases into a summary outlining the
customers readiness, from a network perspective, for unified communications
Communicating how Lync will effect the customer’s network
Provide input to the network engineering team
Analyze traffic simulation to assess UC Readiness
Latency
Jitter
Packet loss
Limit number of concurrent calls
Limit workloads (for example, audio only)
Deploy localized infrastructure
SIP Trunks\gateways
Pools
Provider dropped QoS markings on MPLS
20% not able to send QoS markings
One site not able to send or receive QoS Markings
