Sample Network and Bandwidth Settings

This section lists examples of configuration and bandwidth settings.

Configuration Example

The following example contains marking and Class-Based Weighted Fair Queuing (CBWFQ) with Low Latency Queuing (LLQ) for VoIP. Session Initiation Protocol (SIP) traffic is not treated. The example assumes a LAN Ethernet interface and a WAN Serial T1 interface. Quality of service is configured to guarantee the following:

• Strict priority for four G.729 VoIP calls marked as EF.
• Reserved bandwidth for two 'task worker' PCoIP sessions marked as AF41 (500 Kbps minimum peak bandwidth, limited ability for over-subscription).
• The default class gets all the remaining bandwidth and is fair queued.

Sample router configuration settings:

!match PCoIP packets

access-list 100 permit tcp any any eq 4172

access-list 100 permit udp any any eq 4172

class-map match-all VOIP-IN
match ip rtp 16384 16383
class-map match-all PCOIP-IN
match access-group 100

class-map match-all VOIP-OUT
match ip dscp EF
class-map match-all PCOIP-OUT
match ip dscp AF41

policy-map ETH-IN
class VOIP-IN
set ip dscp EF
class PCOIP-IN
set ip dscp AF41

policy-map SERIAL-OUT
class VOIP-OUT priority 128
class PCOIP-OUT
bandwidth 1000
class class-default
fair-queue

interface Serial 0/1
bandwidth 1544
no fair-queue
service-policy output SERIAL-OUT

!trust dscp markings coming into this router from across the WAN

!do this if you need Layer 2 COS QoS and have a DSCP-COS map defined or set COS on e0/1

mls qos trust dscp

interface Ethernet 0/1
service-policy input ETH-IN

Sample Bandwidth Guidelines

Teradici has developed a list of recommendations for mainstream office scenarios that includes the following worker categories:

• Task Workers: Task workers typically use applications involving simple screen data and text entry, such as call centers.
• Basic Productivity Workers: Basic productivity workers perform text and data entry as well as web-based applications and consume small resolution video content.
• Advanced Productivity Workers: Advanced productivity workers use enterprise-level productivity suites and may consume larger resolution video content.
• Knowledge Workers: Knowledge workers use enterprise-level productivity suites, interactive CD-quality audio communication tools, consume high definition video, and may have some lightweight 3D applications.
• Artists/Designers: Artists and designers perform creative tasks that need high-quality, graphic-intensive rendering for high definition imaging, video, and animation work.

The following table shows recommendations for the different virtual desktop worker categories.

Recommendations for Different Virtual Desktop Worker Categories

The following table compares the different virtual desktop worker categories to the Sample Profile Configurations.

You can use these worker profiles as guidelines when planning your workload requirements in specific user scenarios.

The following table provides example bandwidth estimates for average, video, and burst data rates for a PCoIP session. These bandwidths assume that the displays are 1920 x 1080 or a lower resolution.
