User Management in ADSL Broadband Access Network

ADSL Broadband Access networks are quite common. So I have studied the user management details in the ADSL Broadband Access Network. I would like to share them with you here and hope they will be useful to you. Currently, the billing method of ADSL Broadband Access Network is generally monthly. This method is simple and reasonable in the initial deployment phase when the network speed is low. However, as the network bandwidth and users increase, this simple billing management model will bring a lot of problems.

First of all, this one-size-fits-all billing method cannot distinguish the actual usage of users. If users only have a small number of network applications, but they have to pay a high fee, it will directly lead to user dissatisfaction, this seriously affects the enthusiasm of users for using the ADSL Broadband Access Network. On the other hand, if users use a large number of network resources unlimitedly, it will cause losses to network service providers, this also leads to dissatisfaction among network users who have fewer network applications and are affected by normal network applications.

The network traffic billing method can effectively solve these problems. If you use more network resources, there will be more network traffic. If you use less network resources, there will be less traffic. This billing method is reasonable. You can determine the fee based on the amount of time the user uses the network. In addition, this billing method can give network providers greater benefits and achieve more benefits.

User Management

In terms of user management, it mainly focuses on how to prevent the theft of user data and the theft of traffic. Prevent the theft of user information, mainly to prevent the theft of user addresses. Pay special attention to the circuit encapsulated by RFC1483bridged protocol. Because the encapsulated AAL5 package contains hardware addresses, IP Address Resolution is usually required. Therefore, it may cause serious security problems such as disguised addresses, denial-of-service attacks, and redirection of traffic. You can solve this problem through AddressResolutionProtocol.

Prevent traffic theft (that is, to prevent users from developing their own networks, but conceal traffic from the telecommunications department and do not pay the corresponding network access fees ), the main purpose is to prevent users from using the ADSL Broadband Access Network to treat the host devices on the Internet as proxy servers, and then the clients on the local LAN access external information resources through the proxy server. In general, you can use the Broadband Access Server to authorize PPPoE authentication for users, and record information such as Internet access duration and traffic to discover user exceptions (such as long time occupation and large data flow ), correspondingly, users can be charged by traffic and duration through Radius, or users can be prevented by limiting their access ports.

Broadband access requires protection of narrowband investment. The development of technology is often a process of rapid advances, and the growth of communication services shows a gradual and continuous development trend, the construction of a communication network should seek a future-oriented development path based on the current needs of users. Therefore, it is impossible to build a broadband network in one step. Instead, the network is gradually evolved based on the existing narrowband network and user needs. As a transitional solution, ADSL Broadband Access Network has basically met the needs of current users in high-speed Internet access, lan interconnection, and IP-based broadband multimedia information services. At the same time, it can quickly deploy broadband networks. As long as we can grasp the strength of ADSL Broadband Access Network Construction and pay attention to some problems arising during the construction, we can make full use of the existing copper cable resources of the Telecommunications Department to reduce unnecessary waste on copper cable user transformation, meet current business needs.
