Abstract
The network has become an integral part of people’s daily life. The reason why communication network can realize information exchange and transmission is largely based on the collaborative work of network protocols and routing algorithms, and some hardware facilities. The network protocols and routing algorithms are important elements in designing communication network systems. TCP (Transport Control Protocol) and UDP (User Datagram Protocol) are two transport protocols of the transport layer of the OSI (Open System Interconnection). UDP protocol has the characteristics of high efficiency and fast transmission, while TCP protocol has a slow transmission rate and takes up overhead. Therefore, UDP protocol is used in the communication systems with high requirements for real-time transmission, such as multimedia communication system. In the process of transmission, in order to reduce the burden of CPU on protocol processing, when the length of a UDP segment exceeds the MTU (Maximum Transmission Unit), the IP packet will be fragmented, and the transmission efficiency will be reduced. However, if the length of a UDP segment is too short, the number of UDP segments needed to transmit the same file will increase, which will also limit the transmission efficiency. This paper builds an AVS2 video streaming on-demand system in the Ethernet environment. By changing the length of the UDP data, the video transmission time and bit loss rate will be obtained and used to choose the optimal UDP data length to make the transmission efficiency the highest.
