Course OutlineModule 1: Overview of Network Assessments
This module will introduce you to the goals and considerations that a proactive network readiness assessment takes into account, as well as provide you with the key concepts of networking and telephony that relate to a Lync network readiness assessment.
Before starting a network readiness assessment, it is important to understand basic networking concepts, but it is even more important to identify the reasons to assess your network. The information that you gain from the assessment will inform decisions related to implementing a new product, such as Lync 2013.
A network readiness assessment is an important proactive step toward implementing and deploying new technology in your network. Conducting such an assessment using reliable tools and techniques can help identify issues that your organization might not even be aware of, ranging from possible bottlenecks, to latency problems, to assessing the current level of your network’s readiness, and serving the future needs of your organization.
Lessons

Module 2: Introducing the Microsoft Lync Network Readiness Assessment Methodology
The Microsoft Lync Network Readiness Assessment methodology (MLNRAM) is comprised of four different phases: discovery, modeling, traffic simulation, and recommendations. This module provides an overview on each phase in this methodology.
The objective of the network assessment is to provide insight into the readiness of the network infrastructure for supporting an excellent user experience, while using Lync Server for Real-time Communications (RTC). The network assessment helps to answer the critical pre-deployment question, "Is my network infrastructure ready to support Lync Server?”
Lessons
- Microsoft Lync Network Readiness Assessment Methodology Overview
- Discovery Phase
- Modeling Phase
- Traffic Simulation Phase
- Recommendations Phase
Lab : Discussion
- Discuss Your Network Assessment Experiences
After completing this module, students will be able to:
- Explain the four major phases of the Microsoft Lync Readiness Assessment methodology.

- Discuss real-world experiences with network assessments, processes, and methodologies.
Module 3: Network Discovery
The objective of the Discovery phase is to gain a full understanding of all aspects of the network infrastructure, the existing telephony infrastructure, the conferencing infrastructure, and details of the planned deployment. You should understand the physical topology of the customer’s network, the size and type of their most common WAN connections, and the current levels of data traffic for each site. It is important to remember that all discovery sessions are unique. This module examines several of the key goals of the Discovery phase, such asrevealing potential sources of network impairments, raising awareness of Lync Server traffic flows, confirming the simulation probe placement choice for the traffic simulation, and offering guidelines for network devices.

Module 4: Analyzing Server, Network, and Client Health
The deployment and monitoring portion of the Lync Server lifecycle is where you keep the Lync Server infrastructure running in optimal condition. If planning was properly handled, you will not be expected to fix a backlog of infrastructure issues. Instead, you will be watching for new signs of service degradation and usage trends.
During the Discovery phase of your network assessment, you will use monitoring and managing methods to determine server, network, and client health. This information will help you pose your recommendations to the customer, as well as supply valuable information for the next phases of your network assessment.

Module 5: Usage and Traffic Modeling
Usage and traffic modeling is a key part of a network readiness assessment because you need to know the usage patterns and the actual traffic on the network in order to properly estimate the bandwidth Lync or Unified Communications (UC) might consume on the network.
This moduleintroduces the different usage scenarios, usage models, and personas needed for usage modeling. It covers the process of calculating expected data usage for traffic modeling.
