“…First we explain the method that we are comparing our scheme with. In the method in [21], a new implementation of TCP Vegas that adapts a mechanism based on threshold for controlling congestion of OBS network is introduced. In this paper, for controlling the congestion of the network, a base RTT (round trip time) is chosen.…”

Because Optical Burst Switching (OBN) networks don't have buffers it leads to problems like burst lost and burst contention when arriving at the destination. These problems downgrade OBS networks performances. When traffic of the network is not heavy burst contention can happen, but when it happens the network thinks the traffic is heavy and it decreases the rate of sending bursts when it's not necessary. Another important factor in our paper is Packet Delivery Ratio (PDR). Packet loss can happen in two ways in the network: one is because of heavy load and the other one is because of burst contention. In this paper we adjust the burst size and burst creation time to improve the performance of the OBS network. We simulate our algorithm in NS-2 then compare it with another scheme.

High-speed rail (HSR) communication has always been an attractive research topic with the continuous progress of transportation systems and communication technologies. Recently, Hyperloop has emerged as a candidate for very high-speed transportation systems. Because of its outstanding potential, Hyperloop can usher in a new transportation era with several attractive features. Developing suitable communication system solutions is crucial to bring this promising technology closer to reality. In addition, the Hyperloop communication system is essential to support monitoring-and-controlling services and deliver communication services inside its capsules/pods. Throughout this article, we overview Hyperloop technology and discuss its general characterization to recognize and estimate its relative position among the current HSR communication systems. Then, we investigate different attributes of the communication system, including network architecture, quality-of-service (QoS) requirements, and critical challenges to implement a reliable communication system. With the high speed of the capsule/pod and the system's unique structure, severe Doppler effect and frequent handover may considerably affect the operation of the communication system. Because Hyperloop is a recent development, it is necessary to study the existing HSR communication technologies to determine whether they can establish robust communication links for the Hyperloop system and deliver data with the required QoS. Furthermore, we provide technical details of the current HSR technologies and related research. Subsequently, we present the recent advances in the Hyperloop communication system with classification depending on whether it is a radio-, network-, antenna-, or software-based solution. Finally, we propose future research directions that can promote an improved communication performance.

“…In order to overcome issues of TCP over OBS, several techniques have been presented in literature [26][27][28][29][30][31][32][33][34][35][36][37]. The authors in [26] evaluated the impact of burst assembly algorithms on different TCP implementations such as TCP Reno, New-Reno and SACK in OBS network and in other work [27], they proposed TCP implementation for OBS network called Burst TCP which tries to detect false time out and reacts properly.…”

“…Other technique [36] proposed modification in the burst assembly period at the edge node that aggregates packets from different TCP sessions into different bursts. In [30], authors presented TCP Vegas implementation using a threshold-based mechanism to identify network congestion under burst retransmission scheme. Source-ordering technique over a load-balanced OBS network is introduced by [31] to avoid false time out.…”

In this paper, we consider the performance of TCP when used in data centre networks (DCNs) featuring optical burst switching (OBS) using two-way reservation. The two-way reservation is not suitable in wide-area OBS networks due to high bandwidthdelay product (BDP). The burst loss using traditional methods of one-way reservation can be mistakenly interpreted by the TCP layer as congestion instead of contention in OBS network, leading to serious degradation of the TCP performance. The reduced BDP in DCNs allows the use of two-way reservation that results in zero burst loss. The modelled architecture features fast optical switches in a single hop topology. We apply different workloads with various burst assembly parameters to evaluate the performance of TCP. Our results show significant improvement in TCP performance as compared to traditional methods of OBS as well as to a conventional electronic packet switching DCN.
