摘　　要：随着大数据技术的发展,多线程高并发等技术已经越来越成为大数据处理中的关键技术。非阻塞式I/O(new I/O,NIO)技术作为一种分布式高并发技术被广泛应用,但对于大数据量的通信往往需要很多的时间才能完成。Google提出的Protocol Buffer序列化压缩技术相对于传统序列化效率高、时间短、使用简单。文章将传统NIO技术与Protocol Buffer相结合,在分布式系统不同节点通信中,极大地降低了分布式系统的网络负载,大大节省了数据传输时间。With the development of big data technology,multi-threaded high concurrency distributed system has become the main trend in large data processing.NIO as a distributed high concurrency technology is widely used,but for the data of large scale communication often requires a lot of time to complete.The Protocol Buffer serialization compression technology proposed by Google compared with traditional methods has the advantages of more high-efficiency,faster and easier to use.The article combines traditional NIO and Protocol Buffer to implement communications in distributed environment,which reduces the load of network and saves the data transfer time greatly.
