Lately, WAN Optimization needs have changed from simply bandwidth enhancement and application acceleration to a more application-aware approach that integrates monitoring and layer 7 quality of service (QoS) functionality to enable visibility and control across diverse Enterprise networks.


In reality, as organizations struggle to meet global business challenges, while consolidating IT data and applications, they have created a proximity gap between the users and the resources. As a result, users and data center services have moved physically further apart from each other. Thus, causing applications, files and services delivered over the WAN to suffer in performance, result in poor user productivity and failed IT projects, impacting the bottom line.

To address the performance and productivity challenges of an increasingly mobile and remote workforce, including virtualized environments, WAN Optimization has moved from a tactical style deployment to a tightly integrated virtual WAN Optimization solution for greater control and optimization of business critical applications across distributed Enterprise infrastructures.

Acknowledging that one size of WAN Optimization doesn’t fit all, Expand Networks has addressed the quality and productivity issues of diverse enterprise networks, including virtual environments, by tightly integrating technologies that provide greater control and optimization of the WAN. Thus, delivering 4 to 10 times the bandwidth and a constant service level agreement (SLA) for the user via acceleration, optimization and layer 7 QoS functionality over the existing WAN infrastructure to assure the quality of user experience across complex network environments.

To ensure transparent integration into existing network, virtual or physical, Expand Networks’ (News - Alert) has combined Appliance Accelerator (ACC), Virtual Accelerator (VACC) and Mobile Accelerator client (MACC) into one integrated flexible solution. While ACC is tailored for small and regional branch offices, as well as for data center environments that require scalability and flexibility, VACC is designed for virtual data centers leveraging VMware’s suite of services.

Likewise, MACC with its unique heterogeneous intelligent virtual environment (HIVE) technology transforms the economics of WAN optimization for smaller branch offices and mobile workers within medium to large sized businesses. The MACC’s intelligent location detection provides increased flexibility and mobility as users can move around and the client will provide full WAN Optimization capabilities regardless of location while also providing a distributed ‘Virtual Cache’ for the small branch office (collective branch) avoiding the procurement dilemma of appliance versus multiple clients and IT footprint issues.

In summary, Expand Networks’ integrated virtual WAN Optimization is a flexible solution designed to provide the same seamless user experience wherever users are – Headquarters, branch office, home office, airport, client site, train – putting all data and applications in virtual proximity of users – virtually everywhere.
