Cost, speed choice-increase bandwidth, choose DDN, or accelerate the program?

In the face of slow application of the network, we can have a variety of solutions, such as in the case of the typical application analysis, we will find that, for example, to increase the enterprise network access bandwidth, the use of DDN line, the use of dual-line access, WAN acceleration and so on. However, for a specific network application, enterprises need to choose a suitable solution, need to be in cost, efficiency, effect and other aspects of balance.

Therefore, the focus of this paper is on the efficiency and cost of the enterprise's choice of infrastructure construction, and provides the best solution for the enterprise to solve the network application business.

The first step: Identify the business categories and key issues of enterprise application Internet

To choose a suitable network application slow solution, we first need to the specific network application in-depth analysis of its link within the Data Application category analysis, so that the right remedy.

The internet has become an essential element of enterprise business development (business operation, market expansion, etc.), organization operation (Basic Office, Administrative Affairs), whether for small and medium sized enterprises, or for global wide-area distribution group enterprises. 1M, 2M, 4M, 10M so that the hundred trillion enterprise access is not a company to show off the capital, but to fit your business operation of the "rated" requirements.

From enterprise-level e-business business, enterprise business system (such as Crm,drp,oa) operation, Enterprise financial system (group finance, asset management system, etc.) operation, enterprise Operation process E-Government application affairs (local tax, IRS, industry and commerce, customs, commodity inspection, etc.) processing, enterprise mail system, The application of data sharing and transmission, video audio and instant communication tools among branch offices of enterprises--different enterprises (industry and scale) can be completely different to the application category distribution and focus of the network, but overall, Enterprise's access to the material link the application of all network transmission we can be divided into the following five types from the perspective of application categories:

1. File data Transfer Type applications: File Sharing (CIFS), file transfer, data synchronization (database synchronization, disaster backup), large packet submission, download and other application scenarios.

Feature: Large packets are transmitted in the link. The application shows that the data of 10 trillion, number G and t are transmitted in one way, and many are one-way data transmission.

2. Application of software system load data transmission application: internet-based Enterprise Application System, e-government system, E-commerce system, such as: Group OA, group financial system, distribution management system, ERP enterprise resource System, CRM, customs, commodity inspection, industry and commerce, local tax and other e-government systems provided.

Features: Small packets are transmitted in the link, but the frequency is high, the type of interaction. The application shows that, for a host of high-frequency data communication, the amount of data transmitted each time is small, interactive application frequency is very high. Bidirectional data transmission, such as submission, there are inquiries.

3. Application of instant communication tools for audio and video: internet-based Instant messaging applications. Video conferencing, VOIP,QQ, MSN and other instant tools, Web conferencing and so on.

Characteristics: The transmission of the link is an indefinite length of packets, the size of mixed, high frequency, high sensitivity to the RTT. The application is embodied as a point-to-point or broadcast application system, with the communication application as the main category. Duplex communication, two-way transmission.

4. Information Access applications: mainly reflected in the Internet news browsing, query and so on. Access to Hyper-text pages is primarily.

Feature: The transmission of the link in the variable length file, the host IP address for more changes. The main body of the application is the browsing of hypertext pages.

5. Other (e.g., prescriptive data transmission).

The above is based on the actual load on the enterprise link data traffic from the application category to distinguish. Image, it is similar to a pipe (material link) of the section, Pipeline transmission of Data objects are IP packet data element, but from the enterprise application focus, they have five categories. Different attributes of the enterprise, each category of the application of different weights.
