Embodiment Construction

[0034] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0035] Such as figure 1 As shown, a network protocol address-regional information matching method includes the following steps,

[0036] (1) Obtain the user network protocol address that needs to match the regional information.

[0037] (2) Match the user's network protocol address through the method of sequentially searching the high-frequency region code table. If the matching is successful and the region information of the user's network protocol address is determined, the matching ends.

[0038] (3) Divide the user network protocol address from left to right into four fields: field 1 c1, field 2 c2, field 3 c3 and field 4 c4, and use the binary search algorithm to divide field 1 c1, field 2 c2, field 3 c3 and field 4 ...

Abstract

The invention relates to the field of massive data network protocol address-regional information matching technology, and particularly relates to a network protocol address-regional information matching method and system. The method comprises the following steps: (1) acquiring a user network protocol address that needs to match regional information; (2) matching the user network protocol address through a high-frequently used regional coding schedule according to a sequential lookup method; and (3) dividing the user network protocol address into a field 1, a field 2, a field 3 and a field 4 from left to right, and separately matching the four fields with a low-frequently used regional coding schedule through a binary lookup algorithm. According to the network protocol address-regional information matching method and system disclosed by the invention, the network protocol addresses in the high-frequently used regional coding schedule are sorted according to the frequency of usage and also adopt a sequential lookup matching algorithm; the network protocol addresses in the low-frequently used regional coding schedule are divided into the four fields, and perform matching for the network protocol address-regional information by adopting the binary lookup algorithm; and thus the number of lookups can be decreased in multiples, and the matching efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of massive data network protocol address-regional information matching, in particular to a network protocol address-regional information matching method and system. Background technique [0002] The regional information matching is performed on the data packets of the upstream files sent by the router, so that the data can be stored and researched by region, which can double the value of the data. The method currently used is to query online by obtaining the user network protocol address in the data packet. Although the accuracy is high, the efficiency is extremely low. [0003] Among them, the Internet protocol address (IP) is a protocol for interconnection between networks, that is, a protocol designed for computer networks to communicate with each other. In the Internet, it is a set of rules that enable all computer networks connected to the Internet to communicate with each other, and stipulates the rul...
