5Acceleration for any user, anywhere Repeater appliancesRepeater Plug-inBranch Repeater with Windows Server and Branch Repeater are two different products that have the same hardware form factor.Branch Repeater with Windows Server appliance combines the power of Windows branch services and acceleration features set of Repeater.Branch Repeater appliance has the same great features and user interface as Repeater.Branch Repeater with Windows Server, andBranch Repeater

Branch Repeater MAPI acceleration does not support encrypted MAPI.

Malicious users can break the security perimeter if they get physical access to the domain controller at the branch. RODC solves that dilemma by providing separation in administrator roles and a read-only domain controller for physically less secure sites. This not only improves response times for local users, it allows IT to centrally control the database at the branch. This feature is now available as part of the Citrix Branch Repeater with Windows Server 2008.
10Command Center Enhancements FeaturesNow supports all Branch Repeater appliances (Linux and Windows)BenefitsEasy and cost-effective management of large number of remote sitesWindows based Branch Repeaters can now be managed by both the Citrix Command Center as well as Microsoft System Center.Enhanced Command Center functionality allows configuration archiving, configuration cascading, performance monitoring and alarm generation for multiple Repeaters and Branch Repeaters from a single, unified user interface
11Citrix Branch Repeater Key Features HDX Broadcast & HDX IntelliCacheRepeater Plug-in for Citrix ReceiverPlug-n-Play for Any NetworkIntegrated Windows ServicesFlexible & Centralized ManagementThis sets the agenda for the rest of the presentation. We discuss the key features of the CBR solution, starting with the HDX technologies and going through the soft-WOC client, the versatile networking features, integrated Windows services and central management. The last 2 sections are about the hardware and the FlexLM licensing.

15Adaptive Protocol Acceleration Intelligently accelerates common application protocolsMitigates latency by reducing round trips (chatty protocols)CIFS (File Sharing)MAPI (Exchange)Makes compression engine application-awareSeparates headers from payloadICA, CIFS, MAPI, HTTP, FTP, NFSExample: CIFSCBR detects the application being used and provides additional optimization, beyond that given by TCP flow control and the compression engine.
17Example: CIFS – without Branch Repeater I want to open a file250ms1000 msWhich file?\\dog\bone\blueWho are you?John WhomeverChattiness exponentially increases the workflow time over long distance/ high loss conditions, where the turn around time is high. CIFS (aka Server Message Blocks or SMB) design involves multiple request-responses between the client and server before the user receives any feedback. On a LAN, this exchange completes quickly enough for user to accept the delay. On a WAN, depending on the latency and packet loss, each request-response can add up to a significant amount of time. The end-user experiences a frustrating delay in completing even simple actions like, say, opening a remote directory for file list browsing.Password?“Whatever”OK, It’s open!17
18Example: CIFS – with Branch Repeater Open \\dog\bone\blue for John Whomever, password “Whatever”I want to open a file\\dog\bone\blue“Whatever”John WhomeverWhich file?Who are you?Password?1 ms252 msI want to open a file\\dog\bone\blue“Whatever”John WhomeverWhich file?Who are you?Password?OK, It’s open!125 msBranch Repeater detects a CIFS session and responds locally (over the LAN) to the multiple request-responses by the CIFS client. No changes are required in the behavior of the client, it continues to believe the responses are coming back from the remote server. Based on the packets being received, the Repeaters can “read ahead” or “write ahead” the requests or responses on behalf of the actual client or server. The remote end Repeater works in a similar fashion to communicate with the CIFS device (server) at that end. In other words, the Repeaters complete the CIFS transaction on behalf of the real devices.The advantage of this approach is that most of the communication is completed on the LAN (where latency is almost nil) and very few packets have to cross over the WAN. The end-user experiences a much quicker response to activities like opening a remote directory for file browsing or opening a document on the remote server.1 msOK, It’s open!125 ms18
21Why accelerate MAPI? Faster sending/receiving of email attachments Lessen MAPI-related bandwidth requirementsIncrease mail system responsiveness for branch office usersHelp enable Exchange server consolidationDrastically reduce idle time in sending/receiving sIterations of same or similar messages byOptimization when different users, different applications access similar filesMAPI is the protocol most commonly used by mail applications such as Microsoft Exchange. Generally the server is kept in a central location (datacenter) and the branches (clients) connect to retrieve their mails over a WAN link. Like CIFS, MAPI is a chatty protocol that introduces high latency and bandwidth consumption to a typical mail exchange. Branch Repeater technologies can cut down the chattiness and use compression and de-duplication techniques to accelerate MAPI performance for branch users.
22What is MAPI Acceleration? MAPI Acceleration is:The pipelining of MAPI-based traffic between Microsoft Outlook and Exchange.Acceleration of the uploading and downloading of attachments made to messages.The compression of message attachments.(animation)MAPI acceleration is similar to CIFS in the sense that it reduces chattiness and bundles multiple requests into fewer transactions over the WAN. The CBR talks to the Exchange server to turn off the native compression and offload that functionality to the CBR.

The CBR talks to the Exchange server to turn off the native compression and offload that functionality to the CBR.
24How does MAPI Acceleration work? The Outlook client initiates a MAPI connection to Exchange on TCP port 135.User authentication and mailbox enumeration occurs.Branch Repeater detects the Outlook to Exchange handshake.If an accelerated connection is allowed the native Exchange compression is decompressed on the server-side Repeater.No acceleration = native compression onlyThe Repeater/Branch Repeater pair then apply compression to subsequent MAPI traffic.(animation contains several instructions)A sequence to describe what happens when MAPI acceleration is enabled on the Repeaters
25How does MAPI Acceleration work? A compression bit is flipped in the packet prior to reaching the client, notifying Outlook not to decompress the native Exchange compression.Outlook then creates multiple connections the to Exchange server and message requests are exchanged simultaneously among the connectionsThe downloading and uploading of message attachments (messages larger than 32k) is then accelerated.Appropriate compression is applied to obtain a higher compression ratio.Packet header : Memory-based historyPacket payload: Disk -based history(animation contains several instructions)A sequence to describe what happens when MAPI acceleration is enabled on the Repeaters
26How does MAPI Acceleration work? The acceleration of MAPI is accomplished using several methodsPipelining of ROP requests containing dataQueuing up of upload bytes acknowledged by the client.Pipelining of ROP responses containing dataPre-fetching of bytes of download data to be sent to the client.Aggregation of DCERPC fragmentsMAPI/RPC requests combined into single multithreaded messagesThe pair of Repeaters or Branch Repeaters is aware of all traffic on every accelerated connection.Over time the compression histories on both devices is built up with the most frequently passed traffic.With subsequent requests, the compression history is checked for matches based on packet payload.
27Exchange (MAPI) Acceleration RequirementsMicrosoft Outlook/Exchange Server 2003 and 2007.Outlook must use normal Exchange mode (no HTTP or HTTPS proxy), without encryptionTo disable encryption manually on a single Outlook 2007 client, go to the menu shown uncheck the box, “Encrypt data between Microsoft Office Outlook and Microsoft Exchange’.To disable encryption for multiple users via group policies, follow the instructions at . Change the Properties for “Enable RPC Encryption” to “Disabled” under “User Configuration: Administrative Templates: Microsoft Office Outlook 2007: Tools: Advanced Settings: Exchange.MAPI: Messaging Application Programming InterfaceMAPI is a messaging architecture and a Component Object Model based API for Microsoft Windows.MAPI allows client programs to become messaging-enabled or aware by calling MAPI subsystem routines that interface with certain messaging servers.MAPI is usually used with MAPI/RPC, the proprietary protocol that Microsoft Outlook uses to communicate with Microsoft Exchange.Note – By default Exchange 2007 encrypts MAPI traffic. Branch Repeater MAPI acceleration does not support encrypted MAPI.
33Adaptive TCP Flow Control Sensing and responding to latency and packet lossWith Branch RepeaterAverage UtilizationThroughputTimeWithout Branch RepeaterThroughputAdaptive TCP flow control is the most basic WAN optimization technique that addresses the pessimistic approach in the TCP protocol design. Since TCP is not aware of the bandwidth ‘condition’, it is designed to pump less data on the line to begin with and increase gradually if all packets reach without errors. In case of a dropped packet, the protocol is designed to fall back to half the sending rate and ramp up again. This design helps avoid congestion and retransmissions on poor, low-bandwidth WAN connections.Branch Repeater takes an optimistic design approach and attempts to fill the pipe (sending rate almost equals the link speed). In case of a dropped packet, it does not let the sending rate fall back exponentially and attempts to maintain the average utilization. The intelligent optimizer responds to latency and packet loss by adapting to the line conditions.On modern high-speed, reliable WAN connections this approach:Overcomes high packet loss and network latencyAbility to “fill the pipe” up to 500Mbs+ around the worldWorks for all TCP trafficLink SpeedAverage UtilizationTimeSlow StartSlow Ramp

36Quality of Service (QoS) prioritizes applications 5 traffic classes (or QoS queues)Each queue assigned a min % of the link bandwidthIf queue bandwidth is unused, other traffic can use itQoS is Citrix ICA awareDynamic mapping based on ICA priority bitsQueue specific reportingThe QoS is supported on the Repeater and Branch Repeater appliances. Repeater/Branch Repeater has a unique approach to quality of service (QoS). Traditional QoS isbased on the idea that, if you slow enough traffic down, the remaining traffic will probably move with adequate speed. This is the “apply the brakes” school of network performance. This approach lends itself to elaborate bandwidth-throttling controls and a high level of overall complexity. Repeater doesn’t have any brakes; it represents the “accelerator” school of network performance. By implementing lossless flow control and fair queuing, traffic flows quickly and smoothly of its own accord. Under these circumstances, throttling becomes a secondary technique and a simpler implementation is called for.The Repeater/Branch Repeater uses a rate-based sender for accelerated connections. This means that accelerated data is sent at a constant rate when possible. This rate is selected bybandwidth limits on the two Repeater units involved in the connection. By setting the bandwidth limit slightly lower than the link speed, congestion and packet loss areeliminated, giving ideal link performance.Only accelerated connections are rate-limited. Non-accelerated traffic is passed through immediately.Goal = Fill the pipe

50Multi-user Optimization for XenApp Delivers best performance for XenApp to branch users22-39% faster application start up per user2-6x faster bulk data transfer over ICA + up to 20x less bandwidth consumptionUp to 30x reduction for UPD print traffic over the WAN
51Ideal Use Cases for Branch Caching Multiple users accessing the same text heavy applicationse.g. Microsoft Word or ExcelMultiple users frequently accessing forms-based Web applicationse.g. Call center environment utilizing SAPMultiple users printing similar files within ICAi.e. Universal Print Driver (UPD)Multiple users performing repetitive file transfers within ICAi.e. Client drive mappingMultiple users streaming the same media file within ICAi.e. HDX MediaStreamThese are the five recommended use cases that yield the strongest XenApp Optimization benefits.Where does XenApp Optimization work best? All of these use case scenarios apply to XenApp branch users behind the same Branch Repeater or Repeater appliance (which is generally all users at the same branch).If you have any or all of the above user patterns in branch offices they will see much faster XenApp performance with Branch Repeaters and Repeaters in the network.
52Example: Text Heavy Application User 1User 2Same text between users using Word. Redundant data not sent over WAN.
53Example: Forms-based Web Application User 1User 2These are the four recommended use cases!!!!!Where does the x-session compression work? For ICA users behind the same Repeater:Multiple users, using the same ICA window size and resolution, accessing the text heavy (for example Word or Excel) applicationSame user, without changing ICA window size and resolution, paging up and down the same filePrinting same files inside ICA session or across usersRepetitive file transfer (client drive mapping usage) over ICAe.g. attachments or uploading/download files to serverForm and web browser based apps share background objects between users.

65Deployment Scenarios Integrated mode Standalone mode Merchandising Server is used to deploy Citrix Receiver and plug-insSchedule the delivery for self-service install by end-userStandalone modeCitrix Repeater plug-in is deployed without the Citrix Receiver or Merchandising ServerCitrix Repeater plug-in software is downloaded fromSoftware is customized and deployed using existing software distribution mechanismsThe Repeater Plug-in can be installed as part of the Citrix Receiver. It is also available as a stand-alone client if the user does not wish to install the Receiver. While all the functionality remains the same in both cases, the way the software gets distributed is vastly different. In the standalone case, the user must manually download and install the client. As a plug-in, the software gets delivered during the scheduled delivery by the merchandising server. The user simply needs to accept or decline the install.
66Citrix Receiver Merchandising Server Userplug-in notificationsReceiver(This slide may be hidden as it pertains to Receiver more than the Repeater plug-in)The admin uses the web-based Citrix Receiver administrator console to configure “Deliveries” which are consumed by the Citrix Receiver client. Deliveries specify specific plug-in s to be installed for specific users. The admin can track the progress of those deliveries via a set of Reports in the admin web console.As new plug-in installers become available at Citrix.com, the admin gets a notification within the Citrix Receiver admin console.Notifications: The Merchandising Server polls the Notification Service on citrix.com so as new installers become available it is advertised in the admin console.Installers and Metadata: The Admin downloads the updated plug-in s and uploads the installers and metadata file for the plug-in to the Merchandising Server.Reports: The admin can see reports of plug-in s that have been installed and their status.End-Users at home and work: Citrix Receiver client software is installed on user machines on the LAN or outside the network. It communicates with the Merchandising Server for plug-in updates.Installers and MetaDataAdmin Console

71Benefits of Access Gateway integration Secure and accelerated remote accessCompared to secure access without the Repeater Plug-in, a turbocharged Access Gateway:Improves CIFS performance by up to 30XImproves HTTP performance by up to 50XImproves MAPI performance by up to 50XUp to 99% bandwidth saving with native Windows file shares, Exchange , SharePoint document libraries, and other appsPerformance data is based on Turbocharge Access Gateway Performance Assessment Whitepaper, created June CTXS document code TBD
72Turbocharge Access Gateway Test results showing the performance improvement over different types of bandwidthIn terms of time, the user is able to complete the entire sequence in anywhere from 9 minutes (Cable) to 25 minutes (3G) less than it would take using an un-accelerated connection.The Repeater not only makes a turbocharged VPN connection faster and more efficient, the accelerated connection consumes less bandwidth. Looking at the average bandwidth savings across all three WAN connections, we begin with an immediate 50% reduction in bandwidth consumed when ing the “version 1” PowerPoint. As the user moves through the workflow and Repeater recognizes more and more common data objects in the s, the bandwidth savings escalate to 98%.Complete performance test report is available on

79Approaches to Resolve ‘Asymmetric Routing’ Asymmetric Routing: In a multi-homed environment, a packet on a given connection might travel over either linkGroup Modeallows two or more appliances to be grouped together into a single virtual applianceWCCP modewhere WAN routers send traffic from multiple links to the same appliance (or HA pair), via the WCCP protocol.Virtual Inlinewhere routers send traffic from multiple WAN links through the same appliance (or HA pair).LAN-level aggregationwhere an appliance (or HA pair) is placed closer to the LAN, before the convergence point of the WAN linksGroup mode over non-redundant links with possible asymmetric routingMulti-homing (i.e. more than one Internet service provider) is a necessity in many enterprises to maintain always-on (high-availability) connectivity to the Internet. Citrix Branch Repeaters are designed to address the asymmetric routing that may be created when the packet is presented with a choice of multiple paths on its inward and outward journey. These approaches are listed in this slide.
80Why deploy in Group Mode When multiple WAN links exist.Primary/secondary configurations.Load balanced configurations.Possibility of asymmetric routing issues.Group mode can be used on redundant links without reconfiguring routers.Group mode applies only to the appliances on one side of the WAN link.Appliances in group mode have no affect or reliance on the appliances on the other side of the WAN link.Primary LinkBackup Link
81How does Group Mode work? Within a Group Mode grouping, there is a connection “owner”.The owner of a connection is set by default according to a hash of IP/port pairs.The owner can optionally be set according to specific IP/port-based rules.Group mode uses a heartbeat mechanism to verify that other members of the group are active. Packets are only forwarded to active group members.Primary LinkBackup Link
82How does Group Mode work? If traffic arrives first at the “owning” appliance, it is accelerated and forwarded normally. If it arrives first at a non-owning appliance, it is forwarded to its owner, which accelerates it and returns it to the original appliance for forwarding.In addition, it means that an appliance is available for acceleration even if its link is down.
