What Does a Traffic Manager Do?

Network traffic managers (also known as application traffic managers, bandwidth managers, or QoS devices) have been around since 2000, and were first developed by Packteer in the United States.

Network Traffic Manager (aka Application

However, because network bandwidth issues have not been significant, corporate IT departments have not paid enough attention to bandwidth. With the application of various new network technologies and the development of network multimedia technologies, the problem of shortage of network bandwidth is becoming increasingly apparent. Especially since 2005, P2P applications have brought serious threats to bandwidth management, so the market for bandwidth managers has developed greatly in the past three years. According to incomplete statistics, this market has exceeded nearly 2.5 billion US dollars. China's bandwidth management market has only gradually received attention since 2004. In 2007, China's bandwidth management market share was also 200 million yuan. It is expected that China's bandwidth management market will grow at a rate of more than 20%. Except for foreign Packteer and Allot companies with bandwidth management equipment providers, domestic manufacturers such as Beijing Intellitech, Changxun Technology, etc., the bandwidth management equipment of foreign manufacturers has not yet realized the localization of the interface. China; domestic manufacturers have experienced 3 to 4 years of product research and development, and their products have become increasingly stable. Competition in the market, technology and products will begin in 2008. The basic function of the bandwidth manager is very simple, which is to allocate and monitor bandwidth according to applications and users. Because it is a seven-layer network management device, network managers can directly allocate bandwidth to applications and users without having a high degree of network knowledge, which reduces the investment of network managers to a certain extent. Although the function is simple, there are many applications that can be realized, but most users do not have a good understanding of the application of bandwidth management. Foreign bandwidth management equipment is expensive and does not support Chinese display. Therefore, the applications of Packteer and Allot are mainly concentrated in telecommunications and finance.

In applications such as education and government, the main applications of the bandwidth manager are focused on the management of P2P, especially the management of BT. At the same time, bandwidth management devices have begun to appear as QoS guarantee devices for video conferences. Due to the continuous upgrading of clients for applications such as P2P, only domestic products with independent research and development can quickly implement management strategies based on the new version. International manufacturers have no advantage in this application. Of course, as a bandwidth manager, there are more ways to apply it. Such as the following applications:

First, the problem of network application transparency. Through the bandwidth manager, the status of previously unknown network applications can be viewed in detail.

Second, prevent sudden surges in traffic and attacks from unknown applications, such as DoS attacks, to ensure network security.

3. Evaluate the value of core applications, and understand the utilization and efficiency of core applications through monitoring of core application traffic.

Fourth, to ensure the critical applications (such as: CRM, VPN, wireless networks, video conferencing, VoIP, etc.) required bandwidth, to ensure that critical applications are not blocked at any time

V. Accurately assess the load capacity of the network and the impact of new applications on the overall network application to ensure the rationality of customers' IT investments.

6. Realize the provision of different network resources according to the level of the user, and protect the network value of the core users of the customer.

Seventh, reduce the repeated operations of network management personnel, and provide quantitative data for the application to facilitate management to make decisions based on the application status.

These applications have only appeared in some specific cases, and most users have not yet effectively integrated bandwidth management with their own network management. The application prospect is great.

Product introduction: Allot's NetEnforcer series: The manageable bandwidth is between 2M and 1G. Because network managers are required to have a high level of network technology and do not support some localized applications in China, they are mainly implemented in telecommunications and other international Large-scale application system industry.

The bitSaver product series of Ingenics : its management bandwidth ranges from 2M to 1000M, and its main customers are concentrated in education, government and enterprise units, mainly as management equipment for external networks. Due to the customization function, it can provide user-specific application identification and management, so it has good management performance for domestic software video conference systems, VoIP systems, and online games, Thunder, IM, and so on.

Wan Ren Technology Network Flow Control

Comprehensive perspective of network applications, quickly discover network problems, and quickly locate network faults.

Guarantee the Internet bandwidth of key applications and important personnel, limit the bandwidth of irrelevant applications such as P2P, and ensure network smoothness.

I. Bandwidth Management

Can comprehensively see the application of the entire network, quickly discover network problems, quickly locate network faults, reduce network unavailability time, and improve the unit's work efficiency.

Simplifying the monitoring methods for network applications can reduce the number of IT specialists and greatly reduce the workload and complexity of IT specialists.

Dynamically guarantee the bandwidth required by key employees and key businesses of the unit. When they need to use the network, they can get the guarantee of bandwidth and use the network first; when they are idle, the bandwidth can be used by other services or employees.

Restrict employees to use P2P software or watch network videos during work hours, which are not related to work and consume a lot of bandwidth, which greatly improves the utilization of the network.

Limit the maximum bandwidth of each employee to avoid congestion of the entire unit's network due to individual employees' P2P downloads, watching network videos, and host poisoning.

Limit the maximum number of concurrent connections for each employee, greatly improving the security and availability of the unit network. Prevent the entire network from being paralysed due to the poisoning of individual employee hosts.

By rationally allocating bandwidth, you can postpone or cancel the upgrade of network bandwidth or hardware equipment, reducing the unit's network operating costs.

Adopt load balancing technology: ensure the availability of enterprise applications, improve Internet access speed, reduce server load and management complexity, and reduce unit bandwidth costs.

Server management

Reasonably distribute the traffic of both the server and the staff on the Internet, which can avoid the impact of abnormal traffic on one side on the use of the Internet by the other, thereby more effectively using the unit's valuable Internet bandwidth resources.

Quickly and accurately locate the source of the attack, block Internet attacks on the server, and ensure that the server is safe and stable.

Check the quality of the Internet users accessing the server, and find the abnormal server in time.

Guarantee important server bandwidth and limit common server bandwidth.

Limit the traffic of each Internet user to the server, and prevent individual users from occupying all the bandwidth of the server.

Limit the number of connections between each Internet user and the server, and block network attacks on the server in a timely manner.

Third, dedicated line management

Multiple management devices can be virtualized on one device, and each virtual device manages a dedicated line. A flow control device can manage up to 256 dedicated lines at the same time.

The management of each leased line is completely consistent with the management mode of the customer's Internet total export. It can perform real-time traffic analysis, leased line network quality analysis, historical traffic trend analysis, and leased line bandwidth management and control on each leased line.

Effectively guarantee the network quality of the leased line and improve the efficiency of the leased line.

It greatly saves the purchasing cost of group customers, and greatly reduces the complexity of network administrators' management of dedicated lines.
