The transition from voice to data services has led to new trends in telecommunication business, and therefore the need to adjust legacy metrics and KPIs (Key Performance Indicators) that aims to point out the effects of these changes. In this paper, we give the review of development trends of new KPIs that provide greater insight into the use of data based services, as well as estimating the share...
The rapid growth of high-speed transit systems, such as High Speed Rail (HSR), is putting considerable pressure on TCP-based data transmission. It is well known that TCP is suffering from severe throughput degradation in high-speed mobility scenarios. The root cause at the transport layer however remains unclear and largely undetermined to date. In this paper, we aim to pinpoint the throughput bottlenecks...
Quality of Experience (QoE) is the users' most direct assessment of the network operator's service. How to accurately and efficiently collect QoE data from a point near the user is always a technical challenge to the operators. The way QoE related information submitted to the management system is important because the volume of the data may be excessive enough to interfere with the ordinary chargeable...
There are four integral modules in a Cyber-Physical Networking System (CPNS): sensing, communication, decision, actuating. Among them, the communication module plays the vital role of central liaison. It glues everything together and orchestrates the operation of the whole system. Nowadays, local communications are not enough for practical CPNSs which can be very large in geographical scale. Such...
