The invention aims to provide an implementation method of a fault-tolerant distributed security event data transmission protocol. Security events are handled through a distributed cluster, and event nodes in the cluster are determined through a periodical election mechanism in order to ensure the transaction of message data. A message queue mechanism is adopted for the nodes in the cluster in order to ensure the concurrency and expandability of security event handling. Thus, a fault-tolerant security event transmission mechanism is implemented. The method comprises the following steps that: A, security events in a whole network are handled through an event handling distributed cluster; B, the event handling cluster periodically elects event nodes Transactional; C, scoring factors of event nodes Transactional election are determined; D, one Performer node can process security event transmission requests of a plurality of Performer nodes concurrently; and E, the Performer node processes messages.

The invention relates to the technical field of electronic information and electronic information data operation, and particularly relates to transaction-based large-volume data read and write methods. According to the write method, data records are organized by virtue of data pages and then are subjected to batch processing, and simultaneously, a great deal of transactional write operation is converted into non-transactional write operation, so that the data volume of transactional read and write is reduced effectively; and by virtue of transaction characteristics of index files, the integrity and the transaction of data are ensured, and the efficient read-write of the mass data is achieved. According to the reading method, a data page index is established by a shared memory, and the quick positioning of the data records is realized by using a bisection method. In an occasion that the mass data need to be subjected to the transactional read-write, the transaction-based large-volume data read and write methods can be used for achieving the aims of reducing the IO (input / output) operation, improving the handing capacity and shortening the time delay.

The invention discloses an interactive method based on command line data of a network management system. The method comprises the following steps: converting a network management data model into a command line configuration block; packaging the command line data, and transmitting the command line data to a network device; caching and executing the command line data in batches by the network device; and carrying out rollback on a network management error. According to the invention, the data of the network management system is converted into the command line configuration blocks in batches, and an error rollback mode is supported, in this way, the interaction times of the network management system and the network device are decreased, meanwhile the downloading state maintenance difficulty of the network management data model is reduced, and the network management system is supported to simultaneously release multiple items of data command line configuration blocks; the network management system adds an error rollback mark in the command line to ensure the execution transaction of the data command line configuration blocks, once an execution failure occurs, the original operation on the network device is cancelled by an effective reverse operation; and the network management system optimizes the Telnet echo character, reduces the redundant data and simplifies the data returned to the network management system.
