Quality of Service

Quality of Service Creating QoS policies 20335 07: Understanding Network Controls and Solutions Quality of Service Creating QoS policies  

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.

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

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 49152-54000 Used for audio, the client is configured to use 20 ports; for example, ports 53081-54000. Other servers, such as an A/V Conferencing server, use ports 49152-54000. 54001-60000 Used for video, the Lync Server client is configured to use 20 ports; for example, ports 54001-54020. Other servers, such as a A/V Conferencing server, use ports 54001-60000. 60001-65000 Used for application sharing, the client is configured to use 20 ports; for example, 60001-60020. Other servers, such as a Conferencing server, use ports 60001-65000. 65000-65020 Used for file transfer, the client is configured to use 20 ports; for example 65001-65020. This is a point-to-point file transfer only.

Bandwidth Management with Call Admission Control

Bandwidth Management with Call Admission Control 20335 07: Understanding Network Controls and Solutions Bandwidth Management with Call Admission Control CAC Best Practices

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  

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  

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.

Troubleshooting and Diagnostics Tools

Troubleshooting and Diagnostics Tools 20335 07: Understanding Network Controls and Solutions Troubleshooting and Diagnostics Tools Other troubleshooting and diagnostics tools  

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
