Internet access traffic

Internet access is also worth learning. Many people may not know about the internet access traffic. It does not matter. After reading this article, you must have learned a lot, I hope this article will teach you more things.

1. Requirements Overview

First, the network boundaries must be determined for Internet access. Internet boundaries refer to the boundaries between users' internal networks and the Internet. Their services are divided into two categories, the first type is the internal network to obtain external services from the Internet, such as web browsing, video playback, instant messaging, etc. The second type is the internal network to provide information services to the Internet, such as Web, FTP, and Email.

Internet access requirements at the Internet border can be divided into security access requirements and network traffic management and optimization requirements. The demand for network security comes from the direct access to the Internet through the Internet service boundary. It is the most important way for users to obtain online information and the network boundary with the highest security risks, they are faced with threats such as illegal access, hacker attacks, and virus intrusion. Network management and optimization centered on "traffic" is another important issue facing users. It mainly includes the following aspects:

The traffic for P2P, IM, video download, and on-demand video is rampant, consuming network bandwidth, seriously affecting the use of networks by other users. The bandwidth of key network applications such as MAIL and ERP cannot be guaranteed. Many network users are technically unable to control network applications that consume huge bandwidth, so they have to adopt strict management systems to achieve network control, but they cannot fundamentally solve the problem of network bandwidth occupation. The Internet provides a wide range of public network services for various users. How to Ensure the access quality and performance of these services is also a problem to be solved by bandwidth management.

Employees of various types of enterprises and units connected to the Internet can watch online video, network TV, and online film and television during working hours. They can use various download tools to download their favorite music and video files; play online game legends, Warcraft, lianzhong, anti-terrorism elites, etc. during working hours; chat with instant messaging tools such as MSN and QQ; visit some pornographic and reactionary websites during work hours; use the Internet to publish uncivilized content, or even disclose confidential documents of companies ); these problems arise from the inability to effectively manage internet behavior.

There are a large number of traffic-based attack sources on the Internet. These traffic attacks for the purpose of consuming network resources develop rapidly, but they do not have effective prevention and control measures. A large number of malicious and illegal connections by network attackers consume bandwidth and flood hosts, denial of Service (DoS) attacks. The rapid replication of worms increases the number of scanned packets on the network, resulting in network congestion and high bandwidth usage, thus paralyzing the network. However, the network administrator cannot know the type, source, specific flow direction, traffic size, occupied network port, and duration of abnormal traffic, and cannot effectively plan the use of network resources.

The increasing traffic on the Internet, especially the performance requirements for voice, video, and data, and the mismatch of bandwidth between the LAN and WAN directly results in a decline in the performance of key business applications. How to provide more extensive application services on the existing wide area network without upgrading the bandwidth, and how to get faster application response time, it is a solution that Internet access users are eager to seek.

2. Benefits to customers

Make rational use of network resources. Avoid low network application efficiency and waste of bandwidth resources due to improper use of network bandwidth, and protect users' investment.
Protect key applications and maximize the value of the network. It manages the bandwidth of application traffic to ensure the bandwidth required for application access. When various network applications are running at the same time, it is necessary to ensure the efficiency of key applications such as ERP, Web, and Email, and limit the bandwidth usage of other unrelated applications. Security value-added. Detects and controls network scans, worms, and DDoS attacks, strengthens online behavior management, protects key network assets, avoids illegal leakage of important information, accelerates network applications, and comprehensively improves IT operation efficiency. It ensures that users can operate with limited bandwidth, support more network applications, improve the response time of network applications, and ensure high reliability. The built-in Bypass function automatically switches to the pass-through status when a hardware or software fault occurs. Network Planning Management. By comprehensively monitoring network applications, you can obtain a comprehensive view of network application performance, which facilitates the overall planning and optimization of your network.

3. Applicability

For users with high traffic volumes, such as gigabit traffic and hundreds of megabytes, The LotFlow solution can be used as a comprehensive network traffic management solution, it monitors, controls, accelerates, and manages Internet access traffic. LotFlow can also be used as a professional bandwidth management device to effectively and reasonably control network application traffic; lotFlow can also be used as a professional network traffic analysis device, because all the traffic across the WAN goes through LotFlow, and LotFlow can also listen to network traffic in the SPAN mode, therefore, LotFlow provides users with a complete network application traffic view. LotFlow can also be used as a professional traffic purification device, because LotFlow provides a continuously upgraded library of thousands of attack features, detects almost all scanning, denial of service attacks, and worm-characterized traffic that consumes network bandwidth, and cleans the traffic. Of course, for customers with a few megabytes or dozens of megabytes of network traffic, Huaxia innovation also provides corresponding LotFlow product solutions. It can be said that LotFlow is the best network traffic management solution for such customers, is a real network traffic monitoring, control, acceleration and management solution.
