A communication mechanism between node boards in the system of ATCA 3.1
一种ATCA3.1系统节点板间通信机制的设计

For the problem of data exchanging in management platform between node boards of the system of ATCA3.1, Inter-node communication module was developed. In this module, data were exchanged in manner of messages between different nodes. According to BSD socket interface, the communication mechanism was designed by using address listener and the bottom layer communication channel was encapsulated. The mechanism was implemented in Linux. The result proves that it can solve the communication block problem efficiently.
