IntroductionMore users than ever are accessing their corporate applications and data via a Wide Area Network (WAN), such as the Internet. Whether one works in the telecom or technology industry, the finance sector, manufacturing or even entertainment, chances are that some level of remote access is used to get the job done. Citrix Access GatewayTM is an industry-leading solution for providing secure access for enterprises with large remote and mobile workforces 1 . Access Gateway is a secure application access solution that provides administrators granular application-level control while empowering users with access from anywhere. However, user satisfaction and productivity depends on more than just a secure connection to the network. In many cases, poor quality and slow and unreliable Internet links hinder ones ability to accomplish work quickly and efficiently. This report documents the Citrix solution to turbocharge Access Gateway secure access performance by adding application acceleration using Citrix Branch Repeater products. This marks an end to staring at that hourglass when attempting common tasks such as sending and receiving e-mail attachments, file downloads, Microsoft SharePoint collaboration and backups from, say, a hotel room. The Citrix RepeaterTM Plug-in integrates seamlessly with the Access Gateway Plug-in to provide a high-definition user experience to the remote and mobile worker. The Repeater Plug-in provides the benefits of Branch Repeater solutions to remote users in small branch offices, homes, airports or other locations that do not enjoy the luxury of a Branch Repeater appliance. Citrix Repeater Plug-in is a PC software WAN optimization solution that works in conjunction with a Citrix Repeater appliance located in the datacenter. Adaptive protocol acceleration, compression, prioritization and QoS provide a LAN-like experience over any type of WAN linkwhether it is DSL, T1 or even cellular broadband.

Microsoft Outlook and ExchangeThe benefits resulting from this accelerated, remote access solution are compelling. For example, Microsoft Outlook and Exchange transactions such as sending and receiving large e-mail attachments are up to 50 times faster with a turbocharged Access Gateway.

Figure 1: Microsoft Outlook acceleration with turbocharged Access Gateway 2 Figure 1 compares the time it takes to send a 7 MB PowerPoint attachment over a 3G WAN connection. The chart plots the baseline time without Citrix Repeater and the Repeater Plug-in, the cold run with Citrix Repeater and the Repeater Plug-in (the first time the Repeater Plug-in has seen the data), and the warm run with Citrix Repeater and the Repeater Plug-in (the Repeater Plug-in has seen the data before).

Microsoft SharePointSharePoint transactionssuch as downloading and uploading documents to a document library also are up to 50 times faster with a turbocharged Access Gateway.

Figure 2: Microsoft SharePoint acceleration with turbocharged Access Gateway 3 Figure 2 compares the time it takes to download a 7 MB PowerPoint document from a SharePoint document library over a WAN connection. The chart plots the baseline time without Citrix Repeater and the Repeater Plug-in, the cold run with Citrix Repeater and the Repeater Plug-in (Repeater Plugin has not seen the data before), and the warm run with Citrix Repeater and the Repeater Plug-in (Repeater Plug-in has seen the data before). Windows file sharing transactions such as copy/paste from a file server are up to 30 times faster with a turbocharged Access Gateway. 2 3GWAN,354Kbpsdownload,768KbpsUpload,350mslatency,7MBPPTfileemailedmultipletimes 3 3GWAN,7MBPPTfiledownloadedfromSharePointmultipletimes Page4

Microsoft File ServiceMicrosoft File Service transactionssuch as downloading and uploading documents are up to 30 times faster with a turbocharged Access Gateway.

Figure 3: CIFS protocol acceleration with turbocharged Access Gateway 4 Figure 3 compares the time it takes to download (copy and paste) a 7 MB PowerPoint document from a remote file server over a WAN connection. The chart plots the baseline time without Citrix Repeater and the Repeater Plug-in, the cold run with Citrix Repeater and the Repeater Plug-in (Repeater Plug-in has not seen the data before), and the warm run with Citrix Repeater and the Repeater Plug-in (Repeater Plug-in has seen the data before). Saving time for the user is just one of the benefits. Citrix HDXTM Broadcast and the Repeater Plugin reduce the number of packets sent over the network, generating cost savings on volume-based billing plans. Similar cost saving is seen where payment is by time; the user completes the tasks quickly and disconnects faster. On shared branch links, the ROI can be immediately seen on the saved cost of not adding more bandwidth since the same bandwidth can now serve more users and sessions. Turbocharge and HDX means that Citrix delivers a high-definition experience enabling users to view and interact with content and media.

Figures 4 and 5 are graphs taken from Apposite Technologys Linktropy WAN emulator, which was used for the performance testing. Figure 4 shows that without the Repeater Plug-in, downloading a 10 MB PowerPoint deck over a cable WAN consumes an equivalent amount of bandwidth (10.3 MB) at a throughput of well over 600 Kbps. In contrast, Figure 5 shows that only 0.10 MB of the bandwidth is consumed when transferring the same file with the Repeater Plug-in. Also noticeable in these graphs is the distinct difference in the amount of time required to download the file.
