Quality of Service

Quality of Service in v5.7 and prior releases

• Five queues (Named “A” though “E”. Names can be changed)

• All traffic is assigned to Queue A by default

• Each Service Class can be assigned to a one traffic queue.

• Each queue determines the minimum bandwidth allocation when bandwidth contention with a higher queue occurs.

• ICA Packet priorities are mapped to quality of service (QoS) queues.

Service Classes

ICA Packet Priorities

AccelerationEngine

Quality of Service – The Basics of Traffic Shaping

• All WAN traffic is subject to traffic shaping• Accelerated connections, non-accelerated connections, non-TCP traffic such

as UDP flows, GRE streams, etc.

• The algorithm used is weighted fair queuing• Every connection is assigned a weight based on the appliance’s policies

between 1 and 256.• Traffic shaping is applied to the WAN in both inbound and outbound after the

compression engine• Weighted priorities are applied during bandwidth contention to both ingress and

egress traffic even when the other side of the link is not equipped with QoS.

• DSCP Is fully supported both as a classifier and an enforcer

• More information in Branch Repeater Traffic Shaping technology can be found here http://www.citrix.com/skb/articles/RDY4005

http://www.citrix.com/skb/articles/RDY4005

Quality of Service in v6.0 - Configuration

• Quality of Service is applied using 4 mechanisms.• Links: Tells the traffic shaper which WAN link the packet is using. In a site with

multiple link, each link has its own bandwidth limits and is managed independently.

• Application Classifiers: Identify and determines which protocol or application class traffic belongs to.

• Traffic Shaping Policies: Tell the traffic shaper weighted priority and bandwidth limits to assign to which traffic type (application classifier).

• Service Classes: Map applications to acceleration decisions, traffic filters and traffic-shaping policies.

Quality of ServiceLink Definition

• Links : Physical or Logical• WAN connections between remote sites.• WAN links between datacenters and branches.• WAN links between cities or countries.• WAN data paths between branches and specific

servers or server farms.

Quality of ServiceLink Definition

• Define Links• By Accelerated Port• By Source or Destination Network• By WCCP Service Group• By Source or Destination MAC Address• By VLAN Tag

• By default link definitions are automatically created for each adapter port.

• The number of supported links are limited by Branch Repeater model:• 83xx, 85xx = 5 links• 88xx = 10 links• VPX = up to 5 links

• If Links are misconfigured there will be compression values less than 1:1.

Quality of ServiceTraffic Shaping Policies

• By default there are 10 pre-configured traffic shaping policies. (subject to change)• VOIP Traffic• High Priority Traffic• Medium Priority Traffic• Low Priority Traffic• Default QoS• ICA Priorities

• Each traffic shaping policy has a weighted priority value associated with it.

• The maximum number of traffic shaping policies supported is 50 per appliance.

Quality of ServiceTraffic Shaping Policies

• Weighted Priority is used to determine traffic precedence when calculating send and receive rates.

• And.. Or…

Bandwidth limits can also now used to control allocation.

• Percentage of Link Bandwidth• Absolute Fixed Date Rate.

• Even within an SSL tunnel !!*

*Citrix Patent Pending

Quality of ServiceApplication Classifiers

• Application classifiers are used by service classes to distinguish between application traffic types.

• Applications are classified by:• Ethertype not all competitors can do this

• IP Classification (TCP, GRE, L2TP, etc)• TCP Port• UDP Port• Web URL• ICA Published App not all competitors can do this

• Application classifiers are categorized into 1 of 25 Application Groups

Quality of ServiceApplication Classifiers

• Custom application classifiers can be created.

• The maximum number of classifiers supported is 600 per appliance.

• The classification parameters entered cannot conflict with an existing classifier.

Quality of ServiceApplication Classifiers – XenApp and XenDesktop

• ICA Published Applications or Desktops groups can be manually created or auto-discovered.

• Once discovered, they will appear in the application classifier list as well as in all reports and monitoring pages.

• Temporarily enabling and then disabling auto discovery can be used to prepopulate the online applications list for editing or exporting at a later time.

Quality of ServiceService Classes in v5.7 and prior

• Service Classes in Branch Repeater 5.7 and prior releases identified traffic two possible ways:• IP address/range (client or server)• TCP port number

• Service Classes were evaluated in order with mirrored policies required on all appliances.

• If Service Classes did not match on both appliances with an acceleration pair, those connections would pass through un-accelerated (UR Code 6).

Quality of ServiceService Classes in v6.0

• Service Classes are the main QoS mechanism, bringing together:• Traffic Shaping Policies• Application Classifiers• Link Configurations

• Service Classes are evaluated in order with policies higher in the list having priority over ones lower.

• Service classes need to exist but not be mirrored on all appliances; will result in lowest common setting being used.

Quality of ServiceService Classes

• Service Classes are still used to enforce bandwidth priority among traffic types however now map to Traffic Shaping Policies instead of QoS Queues.

• Traffic Shaping Policies within a Service Class can be applied by:• Single Traffic Shaping Policy per Single

Service Class• Per-link Traffic Shaping Policies per Single

Service Class

• The maximum number of supported Service Classes is 64 per appliance.

Quality of ServiceService Classes

• Service classes can use AND rules as well as OR rules.

• Rules can include any and all of the following filters:• Application Name• Source IP• IP sync/direction• Destination IP• VLAN Tag• DiffServ bit• SSL Profile

• The maximum number of Service Class Filter Rules supported is 10 per Service Class.

Signed SMB / Secure Partner configuration

• Branch Repeater 5.7 and earlier supported compression and acceleration of unsigned SMB1 traffic only.

• If enabled, Signed SMB had to be turned off on servers and clients via group policy to enable acceleration.

• Connections from Vista and Win7 clients had SMB2 connections rolled back to SMB1.


SMB Support in v5.7

• There are three SMB acceleration scenarios you may observe when monitoring SMB CIFS connections.• Unaccelerated SMB 1 or 2 Connections• Accelerated SMB 1 or 2 Connections• Accelerated Signed SMB 1 or 2 Connections


SMB Acceleration in v6.0

• There are three SMB acceleration scenarios you may observe when monitoring SMB CIFS connections.• Unaccelerated SMB 1 or 2 Connections• Accelerated SMB 1 or 2 Connections• Accelerated Signed SMB 1 or 2 Connections

NTLMv1 Required

SMB 1 No No No

SMB 2 No No No

Signed SMB 1 Yes Yes Yes

Signed SMB 2 Yes Yes Yes

• Domain membership is only required on the server-side Branch Repeater.

• Once joined, the appliance or VPX should now have a machine account in the specified domain.

• NOTE: Signed SMB is not enabled yet!


• A secure connection must be established between Branch Repeaters (secure partners).

• SSL credentials (cert and key) are used for authentication and trust between Branch Repeaters.

• The SSL Key Store must be enabled to hold the SSL credentials used by the Branch Repeaters.

• A Crypto license is required to enable the SSL feature set.



• SSL Support must be enabled by clicking the SSL Encryption node under Configuration.

• Trusted SSL credentials must be installed and used to authenticate all Branch Repeaters and create a secure data channel between them.



• The Secure Partner connection is configured on a per appliance basis.

• A signaling mechanism is used to provide discovery and communication between trusted appliances.

MultiStream ICA (MSI)

What is an ICA Virtual Channel? A Citrix Independent Computing Architecture (ICA) virtual

channel is a bidirectional connection for the exchange of generalized packet data between a Citrix XenApp Server and a ICA compliant client.

Virtual channels correspond to virtual drivers; each providing a specific function. Some are required for normal operation, and others are optional.

Virtual drivers operate at the presentation layer protocol level. There can be a number of these protocols active at any given time by multiplexing channels.

There are a total of 32 virtual channels in the ICA protocol. However for most user sessions, between 8 -12 are usually utilized.

ICA Priority Packet Tagging

• ICA Priority Tagging consists of a two bit tag within each ICA packet header.

• These tags can be evaluated on the fly and the application activity determined.

• Earlier versions of MetaFrame use a framing header that does not contain the two priority bits.

Virtual Channels

ICA QoS in BR 5.7 ICA Priority Packet Tagging allows

prioritization of ICA sessions based on the virtual channel data being transmitted. (what the user is doing within the app/session)

This is done by associating each virtual channel’s two-bit priority to a packet priority.

The two priority bits combine to form four priority values: 00 (0) - High Priority 01 (1) - Medium Priority 10 (2) - Low Priority 11 (3) - Background Priority

These priority bits can then be assigned to Branch Repeater Quality of Service queues to allow dynamic QoS.

ICA QoS in BR 6.0 (Single Stream) ICA Priority Packet Tagging allows

prioritization of ICA sessions based on the virtual channel data being transmitted. (what the user is doing within the app/session)

This is done by associating each virtual channel’s two-bit priority to a packet priority.

The two priority bits combine to form four priority values: 00 (0) - High Priority 01 (1) - Medium Priority 10 (2) - Low Priority 11 (3) - Background Priority

These priority bits can then be assigned to Branch Repeater Quality of Service queues to allow dynamic QoS.

The Single Stream ICA Problem

compressed and encrypted ICA data

• The user creates an ICA session.

• User interface traffic is tagged with a priority bit of zero (thin wire).

• Branch Repeater identifies the priority tags in real time and applies QoS appropriately.

Session Bandwidth



• The user then starts a print job within the ICA session.

• Print traffic is tagged with a priority bit of three (real time).

• Branch Repeater identifies the new priority tags in real time and applies QoS appropriately.

Session Bandwidth



• The user then either returns to the app’s user interface or starts a second application. (thin wire)

• The new observed priority bits of the session cause the session to be QoS’ed as a priority zero.

• Prioritization of printing traffic is now lost.

Virtual Channels


• Single-port, Multi-stream ICA (MSI Default)• 4 random ports at client, 1 primary port on server• Automatically enabled on ICA server by Branch Repeater 6.0.

• Multi-port, Multi-stream ICA• 4 random ports at client, 1 primary and up to 3 secondary ports on server• Most common deployment if used without Branch Repeater

• Single-port, Single-stream ICA• 1 random port at client, 1 primary port on server• The pre-MSI default connection type• If any Branch Repeater on the link vetos MSI, or old versions used

Multi-Stream ICA Terminology


Enable MSI on ICA Server


Enable MSI on Branch Repeater

For backward compatibility, MSI is disabled by default on Branch Repeater, XenDesktop and XenApp


Up to 4 TCP connections for a single ICA application

This is the first view that MSI is working as expected


How MSI streams are identified

Under Monitoring Citrix (ICA/CGP) ICA Statistics ICA Session Count

If MSI is active and connected, Multi Stream counter will be non-zero


• Only Branch Repeater can parse a single port/multi-stream ICA connection and apply QoS appropriately.

• The benefits:• Lower overhead on the network and server infrastructure

• Works on standard ICA (CGP) ports, does not require Firewalls reconfiguration

• Hassle-free, automated IT administration

• In all other cases, you get multi-server port MSI or single-stream ICA

What is the competitive advantage

Multi-Stream ICA in Action


• Application UI performance level is maintained.

• Printing traffic does not adversely affect this or any other WAN users.
