Research On Traffic Management Application In 5G Transport Network Equipment

5G technology is committed to solving the exponential growth of mobile data traffic,the interconnection of all things,and various new services and scenarios that have sprung up^[1].The service experience brought by 5G is cross-era,so new requirements are put on 5G transport networks^[2].At this stage,China’s development in the 5G field is obvious to all.At present,China has conducted 5G trials in some cities,and foreign countries have also conducted small-scale 5G trials simultaneously^[3].At present,scholars have made some progress in the research of slice packet network,software-defined network,network function virtualization and other issues,and the technology development of traffic management in 5G transport network equipment is relatively slow.This article proposes an efficient and feasible traffic management solution.Based on the slicing packet network access device and the slicing packet network core aggregation device,the ingress queue applies to the egress queue for scheduling resources to solve the problem of data packets queuing in 5g transmission network equipment.Experimental results show that the method in this paper can basically meet the requirements of 5G for low-latency transmission and large bandwidth.This article mainly discusses:（1）The development status and prospects of 5G are introduced.By analyzing the three major application scenarios of 5G,it shows that the current 5G technology is facing unprecedented challenges.Based on the original 4G technology,it can no longer meet the current needs.Therefore,new technologies the proposal of a new plan became inevitable.（2）Introduced 5G related technologies,mainly introduced flexible Ethernet technology and data packet processing in 5G transmission network equipment.Flexible Ethernet technology uses time division multiplexing to work.The hard pipe characteristics of time division multiplexing determine that the transmission delay of the flexible Ethernet switching structure is smaller and more stable.（3）According to the traffic management process in the 5G transmission network,the traffic management is divided into ingress traffic management,egress traffic management,and fabric traffic management.Among them,the flow management of the entrance and exit is the focus.The difficulty of ingress traffic management lies in the application of scheduling resources,and the difficulty of egress traffic management lies in the allocation of scheduling resources.（4）Simulate the real networking environment and design a suitable test scheme to verify the feasibility of the proposed scheme.The main tests are throughput,delay.（5）Analyze the innovation of the scheme in the article.Dynamic allocation is used to save resources,and service-based compensation is used to refine the rate control of Ethernet ports and flexible Ethernet ports.
