7. Quality of Service

Quality of Service
Creating QoS policies

9. Planning Quality of Service
20335
07: Understanding Network Controls and Solutions
Planning Quality of Service
Planning considerations include the ability to:
Define QoS classification:
Different types of network traffic, with port-based and protocol-based traffic are the most common classification methods
Watch QoS policies implemented on existing switch infrastructures:
They can help ensure that client DSCP markings are not stripped or reset
Achieve guaranteed QoS by enabling DSCP marking of packets as they leave communication endpoints
Be sure to relate your coverage of QoS to network assessment, and not get too entrenched into QoS on its own.

10. Configuring Quality of Service
20335
07: Understanding Network Controls and Solutions
Configuring Quality of Service
Considerations include the ability to:
Verify that the QoS markings in place throughout the network are legitimate:
Avoids configuration issues on the switch infrastructure
Review the planning requirements for network port usage
Address common questions about manual port configuration scenarios such as:
Is it possible to assign a dedicated number and range of ports per Lync Server modality?
What are some of scenarios in which you’d recommend this?
Allocate a separate and dedicated range for each Lync Server modality
Know the DSCP marking standards, 46 has higher priority than anything
Be familiar with how the Microsoft priorities line up with other implementations of QoS

11. Creating Quality of Service Policies
20335
07: Understanding Network Controls and Solutions
Creating Quality of Service Policies
Examples of QoS settings for Internal Edge interface
Make sure you have enough ports, 20 minimum, realistically 40
Ports
Description
Used for audio, the client is configured to use 20 ports; for example, ports Other servers, such as an A/V Conferencing server, use ports
Used for video, the Lync Server client is configured to use 20 ports; for example, ports Other servers, such as a A/V Conferencing server, use ports
Used for application sharing, the client is configured to use 20 ports; for example, Other servers, such as a Conferencing server, use ports
Used for file transfer, the client is configured to use 20 ports; for example This is a point-to-point file transfer only.

12. Bandwidth Management with Call Admission Control

13. Bandwidth Management with Call Admission Control

Bandwidth Management with Call Admission Control
CAC Best Practices

14. Overview of Call Admission Control
20335
07: Understanding Network Controls and Solutions
Overview of Call Admission Control
Main CAC design attributes in Lync Server 2013:
It is simple to deploy and manage without additional equipment, such as specially configured routers:
Creating a complete CAC configuration depends on network complexity
Maintaining a CAC policy depends on change management processes at the network
It addresses critical unified communication (UC) use cases, such as roaming users and multiple points of presence:
CAC policies are enforced according to where the endpoint is located, not where the user is homed
It can be applied to video calls and audio/video conferencing sessions
It provides the flexibility to enable representation of various kinds of network topologies

15. 20335
07: Understanding Network Controls and Solutions
CAC Components
Common network region cmdlets: New-CsNetworkRegion. Get-CsNetworkRegion, Set-CsNetworkRegion, and Remove-CsNetworkRegion
Network region routes that determine which linked path the connection will traverse from one region to another
Network region links that are used to review and configure links between two network regions as part of CAC
Network inter-site policies that define bandwidth limitations between sites that are directly linked

16. Call Admission Control Best Practices
20335
07: Understanding Network Controls and Solutions
Call Admission Control Best Practices
These include the ability to:
Ensure that WANs are adequately provisioned for current and anticipated media traffic
Monitor network usage and call detail records so that you can choose optimal CAC settings and update CAC settings as network usage changes
Use CAC bandwidth policies to complement QoS settings
If you want to reroute blocked calls onto the PSTN, verify PSTN functionality and capacity
Anticipate for future growth when provisioning WANs
Usage may/will change, update CAC as necessary
If reroute is configured make sure of capacity with this new load being moved.

19. Synthetic Transactions
20335
07: Understanding Network Controls and Solutions
Synthetic Transactions
In Microsoft Lync Server 2013, synthetic transactions provide rich logging that records:
The time that the activity started
The time that the activity finished
The action that was performed
Informational, verbose, warning, or error messages generated when the activity ran
SIP registration messages
Exception records or diagnostic codes generated when the activity ran
The net result of running the activity
Examples of actions that were performed include creating, joining, or leaving a conference, signing on to Lync Server, sending an instant message, and so on.
Synthentic transactions for SCOM, be aware they exist

20. Lync Centralized Logging Service
20335
07: Understanding Network Controls and Solutions
Lync Centralized Logging Service
The challenge:
1 Pool, 6 Front End servers
Investigating intermittent client disconnects
Prior to Lync 2013
6x OCSLogger, one on every server
6x Log files, all in different locations, and not related
Where do I start to analyze?
Am I looking at the right server?
Lync 2013 — Centralized Logging Service (CLS):
New in Lync 2013
Replaces OCSLogger & OCSTracer tools
Start/Stop and Flush trace logging on all servers in a deployment from one place
