Heavy traffic on narrow roads could be one of the leading causes of traffic congestion, which also applies to communication networks. If more data is collected than the allowed data capacity can accommodate, communication latency results. This has a devastating effect on 5G-based internet services such as self-driving cars, autonomous robots and remote surgery.

A research team led by Professor Kyunghan Lee in the School of Electrical and Computer Engineering at UNIST has proposed a novel technique that can reduce the congestion issues in the network environment. The team presented their latest work, "ExLL: An ultra low-latency congestion protocol for mobile cellular network" at the ACM CoNEXT 2018, held in Heraklion, Greece, on December 6, 2018.

According to the research team, the new technique has superior performance over Google's Biblio (BBR), which is known as the best low-latency transmission protocol. The performance evaluation and verification were undertaken at home and abroad in collaboration with Professor Sangtae Ha's research team from University of Colorado Boulder, which boasts a mobile communication network testing facility.

Communication delay is a phenomenon in which when untreated data accumulates in the network, causing data transmission delay. This is also called "buffer bloat." When buffer bloats are observed in the data center or the mobile communication network, the transmission of packets is delayed and the efficiency of data exchange and service quality are reduced.

Solution - Transmission - Protocol - Method - Network

A solution to this is a low-delay transmission protocol. It is a method to grasp the network situation and adjust the data transmission rate and reduce the delay. In order to understand the amount of network bandwidth that can be handled by the network in the past, a method of probing the network state has been used by increasing or decreasing the transmission amount per unit time. The amount of data transmission is controlled while considering the...
