Global consistence technology of ARP resource in distributed system

摘要

Raised a new synchronization technology of ARP resource Real-time-batch synchronization technology. This technology is applied on the Ethernet switches. With the usage of this new technology, we achieved a reasonable use of system resources to ensure the consistency of the ARP resources. We use batch synchronization to reduce the utilization of CPU, and use real-time synchronization when the batch synchronization doesn't work. We use dynamic adjustment of temporary storage area size and timing interval to resolve the problem between the data synchronization and the utilization of CPU, and get a better performance. The Real-time-batch synchronization technology also carry out the technologies of ARP detect and ARP attack defense. These guarantee the system's stability and security.
