一种基于应答式地震数传链路与协议的设计

摘要

Basing on the structural characteristics of data-transmission link of DAU and the packets type of DAU transmission, the data transmission protocol are built from division layers function . To solve the problems caused by current Ethernet protocol in the seismic data transmission link, this paper presents a new kind of Response handshake protocol which can enhance management ability of data packets transmission between DAU and reposition error packets in the link.%本文围绕采集站数传链路的结构特点，结合采集站传输数据包的类型，从层的功能划分，来构建数据传输的协议。针对目前在地震数传链路使用以太网协议出现的问题，提出了一种以应答方式进行交互的数据传链路与协议的设计应答式握手协议，旨在加强对数据包在采集站间传输时的管理能力，部分弥补目前通用链路及协议的不足，并对在链路环节中出现的错误包进行重定位。
