The growth of global networks and the popularity of Wide Area Network (WAN) shows no sign of abating and holds the key to unlocking the information pathway that connects the entire globe. A stable WAN infrastructure is now considered to be an imperative. To maximize the utility of WANs, optimization techniques have to be adopted to downplay the inherent weaknesses in network architecture while boosting the performance of WAN networks substantially. WAN optimization improves application performance. Application performance is of utmost importance as business productivity is dependent on it. Oftentimes, it faces restraints owing to the communication barriers across WANs. The three major factors that give rise to such constraints are the following: inadequate bandwidth, latency, and limited WAN resources and application differences. These issues are to be addressed for accelerating WAN performance and ensuring business continuity. WAN accelerating technologies are directed at accelerating a wide array of applications and protocols across Wide Area Networks. Various acceleration techniques including low-level compression, bit wise compression and particular optimization of protocols are employed. WAN optimization is a strategic tool. It aids in solving network issues. As businesses expand across cities, nations, and continents the reach of WANs are truly global in scope. Businesses with branch offices in multiple locations, find it an imperative to employ WAN optimization methods to facilitate robust WAN infrastructure and reduce connectivity failures. Bandwidth and Latency are considered to be the two key factors critical for network performance. Growing number of business are investing in WAN optimization tools to cut down bandwidth costs, improve application availability, maintain applications and modify the IT infrastructure on an overall basis. Network speed is determined by latency, which is one of the key elements of network performance. Latency, generally, is any of the various types of delays that are incurred during network data processing. WAN network latency is conspicuously a major factor that impedes efficient network functioning. Low latency network connections experience minor delays while high latency network connections experience long delays. High WAN latency levels obstruct the data flow in networks. The impact of latency is either temporary or permanent based on the source of the delays. Network latency may occur due to propagation delays, transmission delays, and processing delays. Network tools such as ping tests and trace route are used for measuring latency. It is done by ascertaining the “round-trip time”, i.e. the time taken by a network packet to traverse from the source to destination and vice versa. However, round trip time, though common is not always the way to define latency. WAN optimization solutions can be hardware or software based or a combination of the two. These have the capability to compress data streams, monitor and manage network traffic, prioritize traffic through adoption of Quality of Service (QoS) protocols, and overall management of applications. Recent developments and WAN acceleration techniques have enabled WAN optimization products to ascend the protocol stack in order to resolve WAN latency issues that are built in TCP/IP and other popular network applications. The companies that are focused on business continuity consider a strong WAN infrastructure, a requisite. High data throughput and redundancy are crucial factors, which determine business continuity in organizations. Delays in transmission of data result in low throughput, which in turn can have a profound impact on productivity and profitability. High data throughput is possible only when the Wide Area Network is efficiently functioning without WAN latency and other related obstacles. Minimal response time will consequently increase the data transfer rate. Boosting WAN throughput level is critical in today’s business setting. WAN network latency can be solved to a considerable extent when data is streamlined, the data transportation path made smooth without obstructions, and the WAN is optimized. In the near future, WAN optimization management would encompass technologies integrating business policies, pattern-matching potentiality, and automatic and correlated protocol analysis. Once that is set in place, common obstacles such as WAN latency can be considerably reduced. In combination with these acceleration technologies, businesses are increasingly combining multiple connection WANs as a physical method to improving performance. By adding multiple connections to the WAN, businesses not only improve speed of data transmission, they also provide redundant pathways should one fail. FatPipe Networks, a pioneer in this area, has introduced an array of innovative products to handle a wide variety of network types. Large, medium and small business use FatPipe’s devices to ensure WAN stability and redundancy. As Bandwidth and Latency are two important elements of network performance, WAN optimizing inevitably gives much consideration to the same. Maximum bandwidth utilization is achieved while managing network traffic through load balancing techniques. Management of the two key elements in a coordinated manner makes network performance optimized and consistent. Companies are able to deliver information efficiently through employing unique WAN optimization devices with enhanced features, which drastically reduces WAN latency. FatPipe products have a variety of advanced product features including automatic line failover, dynamic load balancing of IP traffic, site-to-site and unit failover capabilities, which substantially increase the efficiency of Wide Area Networks. FatPipe devices constantly monitor the response time of each dataline and intelligently choose which one to send the traffic on. This saves time, and also enables maximum bandwidth utilization. Companies deploy WAN acceleration and optimization products to efficiently manage processes without disruptions in network connectivity. The ultimate goal is to achieve business continuity.
