WAN optimization provides a range of features to: (1) improve the performance of applications running across the WAN; and (2) reduce the cost of the WAN. The range and scope of features supported byWAN optimization solutions continue to evolve, typically in support of three high-level needs: Improve the response times as experienced by users of business-critical applications over WAN links…
Application delivery controllers (ADCs) are generally deployed in the data center and provide functions that optimize delivery of enterprise applications across the network. ADCs provide functionality for both user-to-application and application-to-application traffic. The ADC effectively bridges the gap between the application and underlying protocols and the traditional packet-based networks. The market evolved from load-balancing systems that were developed in the…
