WAN Optimisation

Does your Wide Area Network (WAN) form the foundation to your business, enabling collaboration, communication, business productivity and risk mitigation?

Do you face the following WAN related challenges:-

  • Increase in Bandwidth requirements
  • Over the WAN Application Performance degradation
  • Connectivity/ Collaboration issues
  • Data Centre Consolidation
  • Hyper-converged Network issues
  • Virtualization
  • Application Acceleration
  • Traffic Prioritization
  • Chatty Protocols clogging your network
  • Accommodating Voice and Video
  • Optimizing the Transport Layer
  • Edge Virtual Server Infrastructure

India Tech Services helps you tackle the above challenges with a set of emerging technologies.

What does Industry say about WAN Optimization:-

WAN optimization is essentially a collection of techniques, including de-duplication, caching, traffic shaping, protocol spoofing and latency optimization, used alone or in combination, for increasing data transfer efficiencies across WANs. In most cases they work in Layer 2 and Layer 3, but modern WAN optimization appliances even work over Layer 7 or application layer.

A WAN optimization controller (WOC) is customer premises equipment (appliance or virtual appliance) that is typically connected to the LAN side of WAN routers, or it is software integrated with client devices, such as servers or routers. WOCs are deployed symmetrically — in data centers and remote locations — and improve the performance of applications that are accessed across a WAN. They address application performance problems caused by bandwidth constraints and latency or protocol limitations, such as TCP and Messaging API (MAPI). The primary function of WOCs is to improve the response times of business-critical applications over WAN links, but they can also help to maximize return on the investment in WAN bandwidth and sometimes avoid the need for costly bandwidth upgrades. To achieve these objectives, WOCs use a combination of techniques, including:

  • Ensuring fair access for mission-critical applications during periods of congestion by prioritizing business-critical traffic, through quality of service (QoS) policing and traffic shaping.
  • Minimizing the effects of network latency using methods such as protocol- and application-specific optimization.
  • Reducing the bandwidth required to transfer WAN traffic by compressing and caching it.
