Recently, I have heard many talk about how to deliver better application experience over WAN to branch users with flat or shrinking IT budgets?

Is delivering a better IT experience to branch or mobile users truly "priceless"? Or do you really need to demonstrate ROI?

It usually takes a lot longer than a year for something to become a 'cliche'. But the current global economic recession has created one of the quickest 'cliches' - 'Flat is the new Growth!' - flat revenues, and flat IT budgets alike.

Faced with flat or shrinking IT budgets, many organizations are clearly and rigorously prioritizing the highest ROI projects, focusing on doing more with less. Increasingly, the following lexicon has taken on a new level of significance and has become part of the IT budgeting process - time-to-ROI, payback time, hard or direct ROI, soft or indirect ROI and so on.

WAN Optimization is one of the very few technologies where IT spend is actually growing while spend on many other technologies is shrinking. In earlier blogs, I blogged about how good the user experience can be with the right WAN optimization solution. But if you are an IT decision maker, you are looking for hard dollar ROI to justify those investments.

We recently published a web-based ROI calculator, designed to show our customers the great savings opportunities available with Citrix Branch Repeater for XenApp and XenDesktop customers. Why don't you try out the calculator and let us know your feedback? We are looking to updating this tool soon based on your feedback.

I look forward to your comments or feedback.

Happy ROI!,

When Citrix first announced NetScaler VPX at Synergy in May, we also announced that we would offer a virtual appliance for Branch Repeater that will be generally available in the first half of 2010. We want to get your input on where, when and how you will use Branch Repeater VPX.

Keep in mind that Branch Repeater is a symmetric solution which means it requires an appliance at both ends of a WAN connection. Today these must be physical appliances but with the upcoming VPX form-factor, one or both could be virtual appliances.

So when, where and how will you use a virtual Branch Repeater? Take our quick poll and then share your comments.

What if you could deliver online (published) apps through XenApp 6 times faster to your branch office workers? Or increase XenApp ICA print throughput by 38 times?

Well, now you can accelerate ICA with Branch Repeater and XenApp. Find out the benefits for yourselves by downloading Turbocharge applications to your branch offices CTX122321 whitepaper. 
Please share with us your experiences, results and thoughts.

Back in 2007 Citrix was one of the first companies to introduce a software-based WAN optimization client to address this need. Initially called WANScaler Client, our software client has evolved and is now called Repeater Plug-in for Citrix Receiver.

As the name implies, the client is now packaged as plug-in for Receiver for Windows. As with all plug-ins, you can use Citrix Dazzle and Citrix Merchandising Server to easily distribute the software to remote users. Once installed, the software appears as the acceleration plug-in under the "Advanced" tab within Receiver and immediately begins accelerating all application traffic.

Not using Citrix Receiver yet? Don't worry. Repeater Plug-in is available as a MSI that can run standalone without Receiver.

Repeater Plug-in for Citrix Receiver supports the same set of acceleration features as the previous WANScaler Client. This includes TCP flow control, compression and application protocol acceleration for CIFS, FTP, HTTP and now MAPI - also added in Branch Repeater 5.5. The plug-in is compatible with leading VPN solutions including Citrix Access Gateway. With Access Gateway we actually accelerate the traffic within the secure SSL tunnel. In fact, just this week we published a performance report showing how you can Turbocharge Access Gateway by up 50x. Check it out.

Ever got frustrated with how long it takes to email a large report or presentation after incorporating your manager's feedback? Or found yourself in a plane wishing the email downloaded faster when the flight attendant asks you to turn off your 3G-equipped laptop? Or wished for a solution that could deliver email 50 times faster?

Did you know our WAN optimization solution, Citrix Branch Repeater, delivers superior user experience and application performance not only for branch office users but also for remote and teleworkers?

No one feels the need for speed more than a remote user or a teleworker with a low-bandwidth or a high- latency network connection. These users typically use an SSL VPN, such as Citrix Access Gateway, to connect to their corporate network and access email, intranet portals, other applications and data. When your IT augments secure remote access (Access Gateway) infrastructure with Branch Repeater, you can benefit from both secure and accelerated remote access.

Well, now we have two reports that demonstrate ways to use Branch Repeater to augment your Access Gateway infrastructure and the resulting benefits of accelerating secure remote access.

You can download the Turbocharge Access Gateway Performance Report - CTX121034 from the Citrix Knowledge Center. The report explores the benefits of using Access Gateway and Repeater plug-ins for Citrix Receiver together:
• 50x faster Microsoft Outlook and Exchange (MAPI) workflows
• 50x faster Microsoft SharePoint (HTTP) workflows
• 30x faster Windows File Shares (CIFS) workflows

I think you will want to try out the benefits of turbocharged remote access. Check out the Turbocharge Access Gateway Deployment Guide and Reference Architecture - CTX121035 if you want to conduct a POC (proof of concept) or a demo to convince your IT or other decision makers. You will be your end-users hero for providing them with an accelerated yet secure remote access.

Over the next few weeks I will be blogging about some of the cool new features in Branch Repeater 5.5.

First up -- Exchange (MAPI) acceleration.

Everyone knows that Microsoft Exchange is the dominant enterprise email server commanding over 65% of the market. Most end users connect to their company's Exchange Server using a version of Microsoft Outlook installed on their desktop. MAPI (or Messaging Application Programming Interface) is the application layer protocol that Outlook email clients use to communicate with an Exchange Server.

As businesses have centralized their Exchange Servers in the datacenter, MAPI has become a top protocol operating over the WAN. By its nature MAPI is a "chatty" protocol which means it performs poorly in WAN environments. Branch Repeater 5.5 now automatically detects MAPI connections and responds by pipelining multiple MAPI messages together for transport across the WAN. By eliminating protocol chattiness, Branch Repeater makes Outlook/Exchange significantly faster over high latency connections.  

Large email attachments are another cause of poor email performance. Branch Repeater addresses this issue by automatically compressing and de-duplicating email attachments.

The results are nothing short of stunning. In many cases you will see performance improvements of 10, 20 or even 50x.

Beyond accelerating the end-user experience, this feature also has a dramatic impact on reducing network bandwidth consumption. Imagine a user in a branch office emailing a 10MB attachment to ten other people in that office. Without Branch Repeater, the entire 10MB file must be transmitted to the Exchange Server and then transmitted back to the branch office ten times - once for each recipient. With Branch Repeater, the attachment is only transmitted across the WAN once.

Branch Repeater's Exchange (MAPI) acceleration is not just for branch offices. The Repeater Plug-in for Citrix Receiver brings this functionality to individual remote users working from home or on the road. Now you don't have to wait forever to download that large attachment while working in your hotel room.

Earlier I said that most users connect to their company's Exchange server using a locally installed version of Outlook. That makes sense since many users need offline access to their email. But wait a minute... XenApp also provides offline access to applications with application streaming. And guess what? A streamed version of Outlook talks MAPI too. So whether you have locally installed Outlook clients or are streaming Outlook with XenApp -- you need to try out Branch Repeater 5.5 in your network.

I am glad to share with you all the news about our Citrix Branch Repeater 5.5. Building on our momentum with XenApp optimization (via the ICA acceleration feature) released earlier this year, we announced today the availability of our newest Citrix Branch Repeater 5.5. Among the many benefits this release delivers, check out the following key highlights:

•  Microsoft Exchange (MAPI) optimization accelerates Exchange email for branch and mobile users by up to 50X while reducing bandwidth consumption. You also get these benefits if you are streaming Microsoft Outlook with XenApp or Microsoft App-V because streamed Outlook application behaves just like a native application from a network perspective - a streamed Outlook will talk MAPI to the Exchange server in the datacenter.  Here is a sneak peek of email acceleration benefits from an upcoming performance whitepaper (available soon): 
   
  
  
   
• Branch Repeater with Windows Server 2008  enables consolidation of essential branch services with Microsoft's most advanced server operating system - Windows Server 2008. Customers now have a choice of deploying Branch Repeater appliances built on either Windows Server 2003 or Windows Server 2008. As before, we continue to offer the non-Windows version of Branch Repeater as well.

• • Of the many powerful capabilities in the Windows Server 2008 operating system, the Read-Only Domain Controller (RODC) feature is one I would like to highlight.  RODC allows you to securely deploy Domain Controller in a branch office for faster Windows authentication and login times. This also helps improve the security posture of IT infrastructure in branch offices.
• With the availability of Repeater Plug-in for Citrix Receiver Branch Repeater now provides WAN acceleration benefits for the already easy-to-use Receiver software client. Receiver provides a consistent and intuitive user experience, and simplifies client distribution and updates. For instance, if you want a single client that provides secure access, SSL VPN client and WAN optimization benefits, then Citrix Receiver is a great way to simplify the client distribution and improve the user experience. This now truly provides simple, fast and secure access to applications from anywhere, whether you are working remotely or in a branch office. I encourage you to try it out and share your experiences with us. 
  

Stay tuned for a series of blog posts that explore some of the features in detail.

Have you been hearing about the new Citrix HDX Technologies? Have you heard that HDX enables branch office users to get that "high definition" XenApp experience? Are you still trying to figure out what this all really means?

• What is driving branch offices to virtualize their applications
• What are branch offices doing about the WAN
• What Citrix Branch Repeater does for XenApp
• How HDX Broadcast and HDX IntelliCache deliver a high-def branch experience

The whitepaper (CTX120455) is available for download on the Branch Repeater section of the Citrix Knowledge Center.

Does your organization deliver virtual applications to the branch office over a sloooow WAN link?
Are you tired of trying to fix all of your WAN issues with a bigger and more expensive WAN connection?

There has to be a better solution...
Citrix Branch Repeater and XenApp work in concert to deliver a "high-definition" branch office experience, drastically improving the XenApp experience to branch office users. Using Citrix HDXTechnology, Branch Repeater and HDX IntelliCache adaptively orchestrate with XenApp to disable the native ICA compression used for optimizing single-user sessions.

Just how much better?

• Branch Repeater reduces XenApp traffic by up to 95 percent, increasing file transfer throughput by up to 20 times and increasing print traffic throughput by up to 33 times.
• Together these enhancements allow customers to serve up to 4x more XenApp users in each branch without upgrading bandwidth.

Learn more about ICA Optimization, how to deploy the components, and see the High Definition branch experience yourself in this exciting demo, which can also be found on the Branch Repeater demo page of Citrix.com.

Another reason you should be using XenApp Platinum edition, Wan Optimization!  The newest feature just added to the complete application delivery system.

What is actually being added?  Now every Platinum license entitles you to use the WANScaler client.

What are the benefits of this feature? 

• Allows the home-based, mobile, or small office user to enjoy the benfits of Wan optimization in situatuions in which an appliance cannot be readily deployed
• Offers comprehensive TCP flow control, advanced compression, and advanced application protocol optimizations to ehnhance productivitiy fo PC users
• Compatible with a wide range of secure remote acess technologies included populat IPsec implementations and Citrix Access Gateway Standard and Advanced Editions.
• Read more here

Will this optimize ICA traffic?  This has been a little tricky.  ICA is already extremely optimized.  In fact, we all know that ICA is one of our biggest competitive advantages.  However, this is something that we are actively testing.  Stay tuned for more information on this soon.

How do I start using this feature? 

1. Again, you must have a XenApp Platinum license with valid subscription as of 1/1/08 (which all Platinum customers will have since it's only been in the market for just a year now)
2. Login to MyCitrix>Support>Downloads>Clients>WANScaler Client or simply click here to download the WANScaler client
3. Also, you will also need either the Citrix WANScaler 85xx or 88xx series appliance available for purchase seperately
