In the era of modern technology, the demand for seamless and fast communication service is gradually increasing. Moreover, as time goes on, more devices are getting connected to the network. In the vast network, for quick responses to these devices, the delay becomes one of the important factors to concern about. Among different types, Queuing delay causes more impact on a network compared to other delays. A survey on delay, different models, effects, and management are illustrated here. Queuing models, like Little Theorem, M/M/1, M/M/m, M/G/1, etc, are discussed in detail. We move on explaining the delay effects on different types of the network such as Wireless network, Mobile communication network, SDN, IoT, etc. This paper also focuses on TCP/IP fields like ECN bits, MPLS, and characteristics of flows. Lastly, the effects of delay on other related networking are discussed.

在现代科技时代，对无缝、快速通信服务的需求逐渐增加。此外，随着时间的推移，越来越多的设备连接到网络。在庞大的网络中，对于这些设备的快速响应，延迟成为需要关注的重要因素之一。在不同类型中，与其他延迟相比，排队延迟对网络的影响更大。此处说明了对延迟、不同模型、影响和管理的调查。详细讨论了排队模型，如小定理、M/M/1、M/M/m、M/G/1 等。我们继续解释对不同类型网络（如无线网络、移动通信网络、SDN、物联网等）的延迟影响。本文还重点介绍了 TCP/IP 领域，如 ECN 位、MPLS 和流特征。最后，
