Applications of video streaming and real-time gaming, which generate large amounts of real-time traffic in the network, are expected to gain considerable popularity in Long Term Evolution networks. Maintaining the QoS such as packet delay, packet loss ratio, median, and cell border throughput requirements in networks dominated by real time traffic, is critical. The existing dimensioning methodology does not consider QoS parameters of real-time traffic in network dimensioning. Moreover, exhaustive and time-consuming simulations are normally required to evaluate the performance and QoS of real-time services. To overcome this problem, we propose an improved radio network dimensioning framework that considers the QoS of real-time traffic in network dimensioning. In this framework, an analytical model is proposed to evaluate the capacity and performance of real-time traffic dominant Long Term Evolution networks. The proposed framework provides a fast and accurate means of finding the trade-off between system load, packet delay, packet loss ratio, required median, and cell border throughput. It also provides network operators with an analytical means for obtaining the minimum number of sites required by jointly considering coverage, capacity and QoS requirements. The accuracy of the proposed model is validated through simulations. [ABSTRACT FROM AUTHOR]

This paper presents the architecture and performance of a new shared media ATM LAN protocol known as pipelined-access local ATM network (PLAN) which has high performance and operates in native ATM mode for efficient and simpler interworking with backbone ATM networks. PLAN is a reservation type bidirectional broadcast bus system protocol in which overhead due to bus propagation delay is limited to a total of twice the end-to-end propagation delay per transmission frame irrespective of the number of stations on the bus. It is designed to (i) support multimedia traffic, (ii) dynamically allocate bandwidth to various types of traffic and provide fair media access to stations, (iii) provide throughput close to 100%, (iv) operate at high bit rates and (v) use packets of ATM cell size and format for interoperability with wide-area ATM networks. In this paper we present the architecture, analysis and performance of the proposed PLAN protocol under various multimedia traffic conditions. The results show that its throughput approaches 100%, is independent of traffic composition and increases slowly with bit rate. It decreases only slightly as the bus length and/or number of stations increase. The proposed PLAN protocol is seen to be well suited for high-speed multimedia ATM LAN and MAN applications in the ATM networking environment. © 1998 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Summary: This paper proposes two novel packet scheduling schemes, called as throughput enhanced scheduling (TES) and TES plus (TES+), for future ultra‐dense networks. These schemes introduce two novel parameters to the scheduling decision making and reformulate the parameters used by the state‐of‐the‐art schemes. The aim is to have a more balanced weight distribution between delay and throughput‐related parameters at scheduling decisions. Also include a new telecommunications related parameter into scheduling decision making that has not been studied by popular schedulers. The performance of novel schemes is compared with well‐known schemes—proportional fairness (PF), exponential/proportional fairness (EXP/PF), and M‐LWDF. For performance evaluation, five performance metrics—average spectral efficiency and delay, quality of service (QoS) violation ratio, jitter, and Jain's fairness index—are investigated. The simulation results show that proposed schemes can outperform all the compared scheduling schemes. [ABSTRACT FROM AUTHOR]
