Zeyu Liu, Kexian Liu, Jing Zhang, Jianfeng Guan · 2021
With the emergence of massive smart terminal devices, the network carries an explosive growth of data traffic. At the same time, the emerging real-time services have a high demand for network transmission delay. The contradiction between the limited network resources and higher delivery requirement derives from the paradigm-shifting of current data transmission. In this paper, we propose a network transmission paradigm with collaborative data transmission and computation processing based on in-network computing and Software-Defined Networking (SDN) to optimize the transmission process and analyze the transmission and computation processing process using image services as an example. By building a transmission delay model, we analyze that the delay can be reduced by using the network-computing collaboration mechanism and give a design of implementation and deployment. Finally, we discuss the problems and challenges according to the current development in the field of in-network computing.
