Abstract

The invention provides an IP (Internet Protocol) header information based shared access management algorithm and an IP header information based shared access management system. The shared access management algorithm comprises the following steps of: when an IP address information is inquired to contain IP address information to be processed, which is received in real time and sent out by a user, acquiring an ID (Identity) number corresponding to the IP address information to be processed in an ID information table, wherein the ID number increases progressively by a fixed added value along with the number of the IP address information to be processed, received in real time; determining the number of ID number segments with continuity in a preset range, wherein the number of the ID number segments is the number of hosts corresponding to the IP address information to be processed; and when the number of the hosts corresponding to the IP address information to be processed is larger than a preset maximum shared host number of the IP address information to be processed, determining the hosts the number of which is larger than the preset maximum shared host number of the IP address information to be processed to be illegal users. The algorithm can be applied to a system and solves the problem that whether shared access internet surfing users exist or not cannot be judged through NAT (Network Address Translation).

Description

technical field [0001] The invention relates to the field of bandwidth sharing, in particular to a shared access management algorithm and system based on IP header information. Background technique [0002] In the network, an IP data packet is also called an IP packet, which is composed of the IP packet user data in the IP packet header. Some fields in the IP packet header can obtain some information about the corresponding host, so it can be obtained through the IP header Some additional information in the article is used to indirectly calculate the number of cascaded computers. The ID number in the IP packet header is on the same machine, and this number always increases according to the "+1" mode. [0003] In the prior art, the method for detecting whether it is a shared access to the Internet is usually address detection, which detects the number of MAC (Media Access Control) addresses under the access layer switch. When the same account has multiple MAC addresses, Then...
