Due to the determinacy requirement of the communication network in distributed IVMS and high reliability avionic system ,the theory of partition communication which conforms to ARINC 653 stand-ard is presented ,the buffering scheme of TTE end-system is studied ,and the partition-TTE communica-tion mapping configuration and partition-TTE communication driver is designed and implemented .Then we built a test platform for partition-TTE communication ,the results indicate that our design of the parti-tion communication based TTE is right and reliable .%针对新一代分布式IVMS及高可靠航电系统对通信网络的确定性通信要求，分析了符合ARINC653标准的分区间通信原理，研究TTE端系统缓冲方案，设计了分区间TTE通信映射配置，实现了分区间TTE通信驱动，建立了分区间TTE通信测试平台，通过实际测试表明，基于TTE网络的分布式系统分区通信方案有效可靠。
