Desktop Virtualization
If you are rolling out desktop virtualization … You need Ipanema!
Your company has decided to simplify application management through the use of desktop virtualization. Desktop virtualization is a technique whereby a remote user does not access their applications on a local desktop (PC) but rather via a “virtual” desktop running on a server in a datacenter. There are two ways of achieving this; either using virtual machines running in datacenters, close to the application servers, combined with proprietary “remote display access” to the virtual machine or by using traditional remote desktop connections to a server running Citrix Presentation Server or Microsoft Terminal Server. With its ability to handle sometimes complex, heterogonous client software in central datacenter locations, desktop virtualization brings a lot of benefits including a dramatic reduction of management costs. However, this consolidation generates a new type of application traffic over the WAN, called interactive flows. These flows need to be managed to ensure proper quality of experience for the virtual desktop users.
Interactive flows often do not require acceleration technologies such as Redundancy Elimination or Application Acceleration. Citrix protocols for example, include native compression. Also, they do not suffer from the chattiness problems of LAN protocols – they are custom designed for use over the WAN. These flows, however, need guaranteed access to resources such as bandwidth be able to deliver good quality of experience. More importantly, as users interact with the remote desktop over the WAN, the interactive flows also require the lowest possible transit delay.
The innovative global, dynamic design of the Ipanema System enables it to guarantee application performance better than any other solution on the market. Additionally, it optimizes more than just bandwidth – it also manages the other important network characteristics: delay, loss and jitter. Application flows are forwarded differently depending on their characteristics and on individual user behavior.
Desktop virtualization can create “hybrid” flows such as when users load or save a local file inside a Citrix document editing session (e.g. one running Word). Ipanema constantly analyses the flow content to detect the user behavior continuously. Thanks to this, Ipanema prevents the data-transfer phases of one interactive flow from freezing other users interactive sessions.
Ipanema's ability to classify the flows up to layer 7, including attributes such as Citrix-published applications is also fundamental, ensuring that the flows will be handled according to their relative importance to the business.
The Ipanema System’s ability to guarantee the performance of critical applications under all circumstances ensures that of virtual desktop users are supported, not impacted by the network.
