查询词典 update data

Accordingly, an optimistic data consistency maintenance method based on key-attributes is proposed. In the method, the update of key-attributes is separated from user update requests. Key-Updates are propagated by latency-overlay update propagation model, that is, updates are always propagated to the nodes having maximum or minimum latency, and assured and uncertain propagation paths of updates are all taken into account. Based on classifying key-update conflicts, a double-level reconciling mechanism including buffer preprocessing and update-log processing is applied to detect and reconcile conflicts, and then conflicts are solved by policies as last-writer-win and divide-and-rule. Lastly, update-log management method and maintenance method brought by node failure and network partitioning are discussed for the above is deployed based on the information storied in update-log.

在该方法中，首先分离出用户提交的更新请求中关于关键属性的更新；然后采用基于延迟-覆盖的更新传播模型进行更新传播，即基于副本间的网络延迟选择具有最大和最小网络延迟的结点转发更新，并在传播过程中记录和综合考虑更新的确定传播和不确定传播两条路径；在对关键更新冲突分类的基础上，采用更新缓冲区和更新日志两层更新协商机制并结合最新写胜出和分而治之规则，优化关键更新冲突的发现和解决；更新日志信息是方法中各种策略开展的基础，讨论了更新日志中信息管理方法以及结点失效和网络划分发生时信息的维护方法。

Therein, by adopting the ISCSI protocol, the local data storage sub-system constructs the circuital access pattern of the taxation data. The system eliminates the unbalance phenomena between the capability and the demand of the data storage under the traditional bus storage pattern. Under the centralized control pattern, it provides the information access and shares service with the great data volume, the high speed of data transportation and the high availability for the taxation system. By remotely building a backup data center that is totally consistent with the local data center on the IT foundational fabric, the remote data backup sub-system uses the geographical dispersibility of the remote data center and adopts the LVR software replication technology. It implements the synchronous data replication between the local and remote data center, changes the zero standing capability on the great disaster event under the single data center pattern and raises the standing capability on the disaster events for the application and data in the taxation system. By adopting the dynamic replication technology between the heterogeneous data source, the heterogeneous data conformity sub-system successfully shields the various heterogeneous ingredients of the present system.

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

This invention discloses a user data process method, which contains 1, judging each data package in IP data steam sent form high layer of empty command protocol stack, if the received IP data package is TCP ACK data package, then executing step 2, if the received data package is not TCP ACK, then executing step 3, 2, making PDCP layer function process to IP data package and ending current process, 3, making flow control to IP data package and then executing 2,, said invention can precedential send TCP ACK data package to opposite part in preserving original TCP/IP and universal mobile telecommunication system data transmission system base, to reduce data package reversion time delay and keep stable data transmission rate.

本发明公开了一种用户面数据处理方法，其主要处理步骤如下：a。对从空口协议栈中高层下发的IP数据流中的每一个数据包进行判断：当前接收到的IP数据包是否为TCP的ACK数据包，对所有是TCP的ACK数据包的IP数据包执行步骤b；对所有不是TCP的ACK数据包的IP数据包执行步骤c；b。对IP数据包进行PDCP层的功能处理，结束当前处理流程；c。对IP数据包进行流控，再转入步骤b。采用本发明方法能够在保持原有TCP/IP和全球移动通信系统数据传输机制的基础上，优先将TCP的ACK数据包发送到对方，从而减少TCP的ACK数据包的回复时延，保证稳定的用户面数据传输速率。

The closest period of time everyday the snapshot circumstance of the website, website already a few months Baidu from collect experienced 10 days now half month updates snapshot to arrive 24 hours to update again to a week, update a few pages to update several much pages to from, arrive 24 hours from 24 hours of a few pages the snapshot of 200 much pages, this paragraph of time understands eventually, to Baidu snapshot should update ability 24 hours to be have weight, baidu did not use PR value to measure the weight of a website like Gu Ge, what does that use, I feel to return is the time that snapshot updates, the jump overing that a website updates in 24 hours has weight more more, because do not think what giving just is Baidu weight really, cannot use PR to see, of course this is pure belong to an individual close a point.

最近一段时间每天网站的快照情况，网站已经几个月了百度从收录到现在经历了十天半个月更新一次快照到一个星期再到24小时更新，从一次更新几页到一次更新数多页，从24小时几页到24小时200多页的快照，这段时间终于明白，对百度来说快照要24小时更新才算是有权重，百度没有像谷歌一样用PR值来衡量一个网站的权重，那用什么呢，我觉得还是快照更新的时间，一个网站在24小时更新的越多就越有权重，因为实在想不出什么才是百度权重，不能用PR一下看出来，当然这纯属个人的关点。
