Design And Implementation Of Data Transmission System Based On RTP Improved Algorithm

In order to respond to the rapid development of expressway construction and ensure that the expressway trunk,interchange,tunnel and other highways to monitor the key sections,to grasp the highway traffic conditions,the timely detection of traffic blocking sections,illegal vehicles,timely Guide,to ensure the safety of the highway smooth.The stability and timeliness of data transmission in front-end equipment(cameras,intelligence boards,car detectors,etc.)is particularly important.The main purpose of this paper is to develop a Gigabit switch based on RTP protocol.It mainly transmits the real-time data of expressway front-end equipment to the monitoring center to ensure real-time monitoring and management of road safety.In this paper,RTP/RTCP protocol as the center axis to start innovative design.Using integrated SWITCH chip 98DX106-LKJ data exchange and transmission,and finally can be a realization of optical data Gigabit convergence and transmission and management of the convergence disk.This topic is designed on the basis of the original 100 M aggregation disk.The benefits of this design are not only mature and stable,but also save a lot of cost.The design uses RTP protocol,the front-end equipment,optical signals and electrical signals converged after the high-speed transmission to the management side.Through the network management system connected by the CPU core card,the system configuration,such as IGMP configuration,Qos configuration and ring configuration,can also obtain real-time status information through the network management system,so as to facilitate the timely management and processing of the problem.Through the CPLD software design of the module between the chip data management and control.The research method of this paper adopts the simulation method,which has certain engineering value.
