摘要
提出了网络安全预警系统中量大—频率高型预警信息的发布算法,该算法将直接由预警代理发布预警信息的方式转变为预警代理首先发布下载元数据,由本地扫描系统根据元数据选择下载节点的分块P2P的下载方式。采用该算法可以降低预警信息发布时预警代理的负载,缩短预警信息发布的时间。
In this paper,an information publication algorithm is presented,which can deal with early warning information of large-amount and high-frequency in NSEWS. In this algorithm, instead of directly publishing early warning information,warning agents publish corresponding meta-data firstly. Then according to the meta-data,local scanners choose some downloaders to get early warning information, using a way of P2P block-division downloading. By used this algorithm, the load of warning agent can be reduced when the early warning information is published, and the time of publication can also be shortened.
