Broadband billing authentication system is designed for the majority of broadband users a precise billing system, and now broadband billing authentication system technology has been greatly improved, the following newsletter to tell you about wireless broadband billing authentication PPPoE authentication technology .

PPPoE authentication technology broadband billing authentication system
pppoe from narrowband technology evolved, ppp is the first designed specifically for Internet and telephone line design, when broadband penetration, for compatibility with previous phone line user habits, it inherited the ppp technology in broadband networks. pppoe is a transition technology has been basically eliminated in stages. For the following reasons:
1, PPPOE is a Layer 2 link technology, can not penetrate the normal three switches, three switches to the transmission, it is necessary to do trunk, that is, as the three-switcher use. This leads to three switches can not realize their full potential, a lot of advanced features three switches can not be used, thus wasting valuable network equipment resources. Also caused some complexity to the overall network planning. If you start using pppoe certification, then later want to use the three-tier exchange network planning function, adjust the overall network, it would be a huge workload.
2, broadband use pppoe way, unnecessary bandwidth consumption, and broadband Internet speed slower than the normal one level. The reason is that use of the broadband packet pppoe than normal, more than two protocol layers, is a PPPOE protocol layer, the other layer is ppp protocol, several protocol layers will be increased to the normal header in the packet header, the data transmission process, more than a lot of additional data, dial-up handshake can have several steps than normal. DETAILED protocol layer data structure is shown in FIG. A:
3, beginning in 2004, ARP *** popular in the network, ARP has nothing to do with PPPOE due to its characteristics, it has the advantage of natural immunity, so there was a lot of occasions for PPPOE high demand.
But after nearly 10 years of network development, along with a variety of popular security software, such as 360, Computer Manager, and a variety of anti-virus software and so already has a function to prevent ARP ***. Therefore, ARP *** has completely disappeared. PPPOE various shortcomings have become increasingly unsuited to the development of broadband networks.
4, PPPOE client is generally applied to the operating system comes PPPPOE, but set up more trouble, there are a lot of steps, the average home user if not familiar, most simply can not handle, then maintenance personnel must carry out door to door-to-door setting, which gives network maintenance is a big workload. Broadband Internet users very negative development and operation, the user often receives complaints about the PPPOE.
5, PPPoE efficiency is relatively low, it can be seen from the PPPoE protocol model, the BAS brought together all data streams of users, it is necessary to open each check PPPoE packets are processed, which is largely followed the conventional PPP manner, once the user many, large number of packets, decapsulates speed requires fast, a lot of energy spent on the BAS detects the user data packet, is easy to form access "bottleneck."
6, PPPOE way thanks to the layer 2 link, it has a three-tier package to prevent ARP *** great way to safety, but PPPOE itself but there are insecure protocol, since certification is PPPOE broadcasts, in net As long as the inner segment attached network sniffer, PPPOE package can be intercepted and redirected to do any modification. About PPPOE Security Vulnerability Description see last reference "PPPOE verify the harm caused by defects."
