In today's attention to mission-critical applications and the immediate response of the generation, data delayed stifled the user experience. Gartner research institutions that delay is "the application performance of the silent killer", a delay hindered the user to enjoy the benefits of WAN, but also makes wide-area network (WAN) can not develop their potential. Therefore, service providers and users would like the issue of delay can be resolved, at the same time play the application's performance.
With the consolidation of IT resources and web applications for internal and external users by the change, customers have become very dependent on the smooth and safe transmission network in order to achieve applications. However, even when there are sufficient bandwidth, latency (network transmission document the time spent) will also reduce the efficiency of application.
Delay is a method to solve the realization of the entire WAN application acceleration, and strive to achieve the transmission speed local area network.
The wide area network optimization
Accelerate the application of a new generation of wide-area network optimization solutions. An application acceleration solutions may be a hardware, a package or two of the integrated. The Internet or by reducing the number of data transmission network, these solutions can accelerate application delivery. Through the use of sophisticated data compression algorithm that can achieve this purpose.
Reverse - positive cache technology is another way to accelerate the flow. Users do not have to have been from the remote server to receive, in their access client, hidden in local memory. By easing congestion and speed up SSL encryption so that the transfer protocol optimization, while addressing such as Microsoft's CIFS (a tedious document processing agreement, originally designed for LAN operations) of such general agreement document the problem. The rapid messaging (MAPI), the Microsoft Exchange Server and Outlook e-mail clients used by the agreement, is another benefit a lot from the acceleration of the agreement.
What is driving the demand for application accelerator »
Decentralized business model (in the traditional concept, which is a strategic approach) to promote the application of the threat accelerator market profit growth, become a potential corporate debt. Delay only accelerate the market for one of the factors, other factors including:
Server decentralization: the decentralization of resources could achieve the effective control is to comply with government regulations and ensure business continuity in the key. As the "Sarbanes - Oxley Act" (The Sarbanes-Oxley Act (SOX) and "The New Basel Capital Accord" (BASEL II), such provisions require companies to protect their critical applications and customer data ( As in the case of patients with medical information), control access to data and prove that they aim to achieve the protection of the measures taken and when applications, data and resources have been concentrated in a few regions, to provide for the protection of the highly decentralized state, More easily.
WAN Capacity: WAN link with limited bandwidth. When a user tries to spread throughout the enterprise network sent more rich content, such as page images, multimedia and other large-volume document, which has become one of the obstacles can not be ignored. Through consumption than traditional client / server at least up to 10 times the bandwidth, the traditional web application to the problem worse. Faced with the pressure, including the costs, IT managers can not expect only the help of additional bandwidth, we can find a way out.
Feasibility: not connected to data centers and enterprises in other sectors connected equipment, work will stop. To create a smoother-based applications, the network can understand a higher level (from 4-7) the content and services, transport services is bound to complete the conditions. Equally important is the uninterrupted operation in the workplace, there should be a number of branch offices and remote users connect the line to ensure uninterrupted business processes in the case continue.
Competition: because the manager or the end-user enterprises will deploy more applications, applications (the same requirements of the limited bandwidth) will intensify the competition between. This will lead to business-critical applications for non-critical communications traffic and slow down. Therefore, to ensure that application performance and reliability requirements of a fully compatible with a high degree of reliability of the wide area network optimization controller.
Security: As the mobility of employees, companies need to provide for their employees access to enterprise applications and other major decentralization of resources means security. In many cases, secure access must be extended to enterprises such as customers and partners such "an outsider."
Manageability: IT managers can not control or manage their invisible things. If IT managers fail to spread awareness of what is happening in the business, the ability to control or change their on how best to improve the performance there will be no clear concept.
Support: data replication and disaster recovery high on the feasibility of a key role. Since the establishment of enterprise data centers away from the support of the original location, so they can not send high-bandwidth, low-latency server, allowing the copying of data, can not meet their recovery point objectives of the request. Enterprises must overcome the technical obstacles, so as to avoid loss of data to ensure that in the event when faced with catastrophic events, to carry out a smooth switch.
Changing attitudes
Taking into account the trend and the driver of factors, wide-area Internet companies are re-visit the application accelerator, as part of its strategy to optimize and create new customer value and unique competitive advantages.
To Cathay Pacific Airways as an example. In order to support the future expansion of Cathay Pacific Airways need to upgrade networks, all from the private system needs to change public system. The system can use IP-based applications, improve customer experience. Companies selected Juniper Networks WX series WAN application acceleration platform is in order to accomplish this task. As a result, high-speed links, and do not respond to the demand for equipment upgrades, Cathay Pacific wide area network capacity increased by 68 percent, and the existing network to minimize interference and effective by eliminating the demand for more high-speed connections and equipment to update the savings Cost.
Another example is BuzzCity Pte Limited. Singapore-based BuzzCity Pte is a mobile applications and content delivery company. The company needs to support its core business of the Web current and future performance, while reducing the expansion of applications and hardware costs. By Juniper Networks DX Series platform, provide load balancing and application acceleration, the company can easily break through the heavy before the monthly 75 million to 90 million page views, while supporting up to 60:1 for the customer's server ratio.
The last whole year, Juniper DX and WX series series solutions in the IT industry was the rapid growth in profits. This reflects the return of the IP network operators expect traffic growth, its causes, including further strengthen the interaction and so on, the use of broadband, video and continuously enhance network reliability. IP network provider in which the strategy and their corporate customers is a key business tool. In addition, the market is showing a high-performance, integrated solutions development of the momentum to improve operating efficiency.
Application acceleration solution seems to be a change in thinking. The rules of the game is no longer guarantee the normal operation of a second time or output or even trading volume. Today's network goal is to provide users with compatible, high-performance, reliable and safe application of experience.
