An overview of queuing delay and various delay based algorithms in networks


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.
