Adapting WAN Optimization
Over the past few years enterprises have become more responsive in delivering better performing and highly visible applications over the web. With the rapid involvement of Cloud in transforming the technology arena, most of the software applications are being converted to web-based versions, where WAN plays a vital role.
Wide Area Network (WAN) optimization or WAN acceleration includes the strategies and techniques to maximize the data flow efficiency across a WAN. The ever evolving user requirements, growing IP sector is influencing the WAN optimization trend. Moreover, the increasing demand for WAN optimization-as-a-service is driving the WAN optimization market with its efficiency and flexibility. A recent report by marketsandmarkets.com states that, “WAN Optimization Market worth $12.1 Billion by 2019.”
MarketsandMarkets also reports that the market is expected to grow to $12.1 billion by2019. This represents an estimated Compound Annual Growth Rate (CAGR) of 18.8 percent from 2014 to 2019. The report also states that in the current scenario, North America is expected to be the biggest market on the basis of spending and adoption of the WAN Optimization hardware and services, and APAC is the highest growing region with a CAGR of 21.2 percent in this market. The notable players in this market, who contribute to the major share, include Array Networks, Aryaka Networks, Blue Coat Systems, Citrix Systems, Exinda, Ipanema Technologies, Riverbed, and Silver Peak.
WAN optimization is a set of strategies and techniques to increase the data transfer efficiency across a network. The hardware and software components that are used to perform WAN optimization are known as WAN optimization controllers. The data transfer efficiency of a Transmission Control Protocol (TCP) are measures of throughput, bandwidth requirements, protocol, the latency and the network congestion based on the packets dropped. These applications are commonly used for business applications like email, database applications, content management systems, and web delivery systems. However, the huge initial investment is one of the major challenges that the vendors are facing in installing a WAN controller.
The WAN optimization technology is deployed at both the ends of a WAN link that can be hardware, software or a software client. Take a look at some of the benefits in adopting WAN optimization technology.
Organizations can consolidate branch connectivity and services into the WAN optimization controller that is known as Branch Office in the Box. This can consist of applications, connectivity, as well as security.
As WAN optimization speeds and improves the overall efficiency of the WAN, it gradually improves the application response time as well as transfer speed over the WAN.
The advanced form of WAN optimization called as the Next generation WAN optimization that enables more efficient mapping and support for data signals including the Ethernet and the internet Protocol. The upcoming technology is expected to enhance the overall performance of WAN optimization deployment for efficient and flexible optimization.
Faster File Access
With the file caching technique, frequently accessed files can be accessed faster as the full document need not be retrieved every time the user requests. Moreover, as WAN optimization improves network speed between remote locations, file transfers as well as network-based communications becomes faster.
