| Béatrice for Ipanews: What is SWAN? Frank Lyonnet: SWAN stands for “Strategic WAN Acceleration Navigator”. It's an interactive web-based questionnaire that only takes a few minutes to complete and that instantly produces a customized report covering an enterprise’s entire situation and the associated requirements for WAN Acceleration. It outlines what people should look for to deliver excellent application performance to users—at the right cost. SWAN also proposes a multidimensional score that summarizes the report. BD: Where does the idea for SWAN come from? FL: Managing the WAN is no longer only a question of bandwidth and pipes; it's also a question of applications and productivity. There are a lot of technologies out there that each provides a piece of the puzzle. Some specialized vendors emphasise one or two aspects of application performance optimization. Since they are not positioned to provide a full answer, their marketing messages tend to be confusing for enterprises.  BD: How can SWAN help to get a clearer picture of requirements? FL: SWAN is not about technologies; it is instead centered on real situations that make up the daily life of network managers. There are questions about concerns, such as application performance brownouts. Users of SWAN are asked if this represents an issue for them, and if it does, then to what extent. SWAN also considers the major IT transformations or projects that rely on the WAN. From these inputs, SWAN provides a personalized analysis that connects a given enterprise situation to technology requirements in a top-down approach. I believe this is the right way to go. It’s time the market stops looking at bits and bytes and starts to consider the end game. The network has to support the IT strategy of the enterprise, not the reverse. BD: I’ve seen a graph called the “SWAN score” in the report, what is it? FL: The SWAN score is a key element of SWAN. It’s a graphic that maps an enterprise situation in terms of five key benefits: User Experience Guarantee, Business Application Acceleration, Network Operations Simplification, Cost Reduction and finally WAN Governance. As the user answers the questions, the SWAN score evolves along these five axes to show the requirements and how solutions can address them. BD: Are there also ROI figures in SWAN? FL: Sure! Ipanema has just built a great analysis tool called TSI or Total Savings Impact. Instead of looking only at bandwidth savings, TSI considers all the economic impacts of Ipanema solutions on company finances. This includes savings in terms of operation costs, IT consolidation and other aspects. SWAN includes a simplified TSI model that updates dynamically as the user answers the questions. BD: Updates dynamically? Really...? FL: Yes, SWAN was created as a way for people to learn while having a bit of fun. Before they push the “analysis” button to create their very own white paper, they can play with the tool to see what relationship exists between the different projects they have in mind and WAN Acceleration requirements. BD: Am I wrong, or is there nothing like SWAN in this market? FL: No, you are not mistaken; SWAN is unique so far. At Ipanema we like innovation, we have been innovating for years and we are today recognized as pioneers in the exciting field of Autonomic Networking. But it’s not only about innovation; we strongly believe that WAN Optimization is an enabler of something bigger that we call WAN Governance. WAN Governance is about making the WAN a key asset of an enterprise’s success and productivity. This is what Ipanema enables and SWAN helps enterprises to understand how and why.
