为了解决BitTorrent协议中 tracker统计数据完整性的问题,我们可以添加一些代码验证tracker报告的DL / UL统计数据是否与实际下载和上传量相符。
以下是一个可能的解决方案示例:
int reportedDownload = 0;
int reportedUpload = 0;
/* parse tracker response */
int responseDownload = ...; /* extract download amount from response */
int responseUpload = ...; /* extract upload amount from response */
/* update reported values */
reportedDownload += responseDownload;
reportedUpload += responseUpload;
long currentDownload = ...; /* current number of downloaded bytes */
long currentUpload = ...; /* current number of uploaded bytes */
/* calculate actual values */
long actualDownload = (currentDownload - previousDownload) * 60; /* bytes per minute */
long actualUpload = (currentUpload - previousUpload) * 60; /* bytes per minute */
/* compare with reported values */
if (reportedDownload != actualDownload || reportedUpload != actualUpload) {
/* statistics mismatch detected */
handleMismatch(); /* handle the error as appropriate */
}
/* update previous values */
previousDownload = currentDownload;
previousUpload = currentUpload;
通过这些代码,我们可以确保tracker报告的下载和上传量与实际值匹配,从而提高数据的完整性。
