Enterprises have become increasingly dependent on their networks to deliver applications and data access to users throughout their organization, not only at corporate headquarters but also to branch offices and locations around the world. As employees become increasingly dependent on access to applications to perform their job functions, it is paramount that the Wide Area Network (WAN) provides the highest level of performance possible.
The emergence of WAN optimization in recent years has resulted in significant gains to the enterprise in terms of application performance, reduced network costs, and improved employee productivity and customer satisfaction. To date, the majority of WAN optimization efforts that have been concentrated in branch offices deployments were available primarily as dedicated appliances.
IDC research has found the demand for WAN optimization to be broad based among a large variation in the types of users, types of traffic patterns, and geographical mix of remote offices. As a result, in addition to evaluating the immediate benefit of WAN optimization, customers evaluate a number of factors within their own unique network configuration, including the cost to deploy and manage appliances as well as their relationships and contractual obligations with service providers.
