GECISM中的回滚、备份与设障

Rollback, backup and obstruction in GECISM

检查点技术用来对系统中正常运行的程序有效状态进行备份,当系统出现故障时,可以根据最近的检查点恢复当前失效的进程,减少计算的损失。由不同的代理构成的计算机免疫系统GECISM(GEneral ComputerImmune System Model)是把生物免疫系统的机理用于计算机安全领域的一个产物。通过比较多种不同的检查点机制,选择利用缓冲回滚系统BRAS(Buffering RollbAckSystem)检查点机制实现GECISM中类TD代理功能,使系统回卷到以前洁净点状态。

Checkpointing technology is used to reduce the computing loss through saving the valid state of normal running processes and restoring the disabled process according to the newest checkpoint after the system failures. Computer immune system GECISM (GEneral Computer Immune System Model) which constituted by multi-agents is a production of the immune system applying in the computer security field. By comparing several different checkpoint mechanism, the TD agent in GECISM utilizes BRAS (Buffering RollbAck System) to realize its function, and makes the system rollback to the recent cleanliness status.
