#include "geoip.hpp"

Overview

GeoIP Query geographic location ID based on IP.

Parameters:

uint512	512-bit wide unsigned integer data type
uint64	64-bit wide unsigned integer data type
uint32	32-bit wide unsigned integer data type
uint16	16-bit wide unsigned integer data type
Len1	The number of IPs placed in a 512-bit wide data
Len2	The number of networks placed in a 512-bit wide data
TH1	Query the query depth of the IP range
TH2	Query the depth of the query where the IP is located

class GeoIP

Methods

GeoIP

GeoIP ()

GeoIP constructor.

init

init overload (1)

void init (
    uint32 len,
    uint64* netHigh16
    )

brief init Initialize parameters

Parameters:

len	The length of netHigh16, default value is 65536
netHigh16	The netHigh16 store the position of the lower 21 bits of the network in the DDR

init overload (2)

void init (
    uint32 len,
    uint64* netHigh16,
    uint32 ipPosIn
    )

brief init Initialize parameters

Parameters:

len	The length of netHigh16, default value is 65536
netHigh16	The netHigh16 store the position of the lower 21 bits of the network in the DDR

run

run overload (1)

void run (
    uint32 len,
    uint32* ipIn,
    uint512* netLow21,
    uint512* net2Low21,
    uint32* idOut
    )

run GeoIP ‘s core execution module

Parameters:

len	The length of IP
ipIn	The input of 32bit IP
netLow21	The low 21bit of the network
net2Low21	In order to achieve faster throughput, the content is the same as netLow21
idOut	Return the id result of the query, 0xFFFFFFFF means the query failed

run overload (2)

void run (
    uint32 len,
    uint64* msg,
    uint16* msgLen,
    uint32* fieldOffset,
    uint512* netLow21,
    uint512* net2Low21,
    uint32* idOut
    )

extract IP from full message then run GeoIP ‘s core execution module to find the ID.

Parameters:

len	The length of IP
msg	the input message
msgLen	the input length of each message.
fieldOffset	the input offset for each sub-stirng
netLow21	The low 21bit of the network
net2Low21	In order to achieve faster throughput, the content is the same as netLow21
idOut	Return the id result of the query, 0xFFFFFFFF means the query failed
