Today, mobile devices like smartphones are supported with various wireless radio interfaces including cellular (3G/4G/LTE) and Wi-Fi (IEEE 802.11) [42]. The legacy devices can only communicate with only one interface. The Transmission Control Protocol, or TCP, has a limitation inability to change connection settings without breaking the connection. In this paper, we explain how multi-path TCP (MPTCP) protocol has been proposed to solve TCP single-interface limitation and provides a huge improvement on application performance by using multiple paths transparently (auto path changing). We discuss the last mile, which is the final networking segment that carried all network traffic. Indeed, the available bandwidth in last-mile link can effectively harm the network throughput as it limits the amount of transmitted data. We found that the quality of the last mile networks significantly determines the reliability and quality of the carrying network. We believe MPTCP can provide a convenient solution for the last mile problem. We provide a holistic view of the challenges and potential enablers in details.<br>

<div>Today, mobile devices like smartphones are supported with various wireless radio interfaces including cellular (3G/4G/LTE) and Wi-Fi (IEEE 802.11) [46]. The legacy devices can only communicate with only one interface. The Transmission Control Protocol, or TCP, has a limitation inability to change connection settings without breaking the connection. Multi-path TCP (MPTCP) protocol has been proposed to solve TCP single-interface limitation and provides a huge improvement on application performance by using multiple paths transparently (auto path changing). The last mile is the final networking segment which carried all network traffic. The available bandwidth in last-mile link can effectively harm the network throughput as it limits the amount of transmitted data. The quality of the last mile networks significantly determines the reliability and quality of the carrying network. MPTCP can provide a convenient solution for the last mile problem. An MPTCP scheduler needs to provide significant packet routing schedules based on the current status of paths (sub-flows) in terms of loss rate, bandwidth and jitter, in a way, maximizing the network goodput. MPTCP extends the TCP by enabling a single byte stream split into multiple byte streams and transfer them over multiple disjoint network paths or subflows. An MPTCP connection combines a set of different subflows where each subflow performance depends on the condition of its path (including packet loss rate, queue delay, and throughput capacity). Unreliable packet scheduling may lead to critical networking issues such as the head-of-line (HoL) blocking where the packets scheduled on the low-latency path must wait for the packets on the high-latency path to ensure in-order delivery and the out-of-order (OFO) packets, the receiver must maintain a large queue to reorganize the received packets. In this project, we aim to study and experiment MPTCP scheduling on dynamic networks (like a cellular network) and try to propose an MPTCP schema which can be effective to overcome limitations of dynamic networks performance.</div>

Transmission Control Protocol (TCP) is a type of protocol that allows a collection of computers to communicate and exchange data within a network. Nowadays electronic devices such as tablets, personal computers and smartphones can use more than one network at the same time, but this is not supported by the characteristics of TCP which can only use one path on the network. To solve this condition there are several new generations of standardized network protocols. Multipath TCP is a development of TCP, Multipath which is a new generation network protocol that allows traffic to use multiple paths in the network. In addition to being able to use multiple paths on multipath TCP, there are several congestion control algorithms including LIA, CUBIC and WVEGAS congestion control algorithms. Tests conducted in this study were to compare the performance of congestion control LIA, CUBIC and WVEGAS to improve the quality of video streaming. From the test results, CUBIC is better than WVEGAS and LIA because the QoS and QoE video streaming test for CUBIC in all testing environment has better results than others.

Insight Into

Network communication has become a part of everyday life, and the interconnection among devices and people will increase even more in the future. Nevertheless, prediction of Quality of Service parameters, particularly throughput, is quite a challenging task. In this survey, we provide an extensive insight into the literature on Transmission Control Protocol throughput prediction. The goal is to provide an overview of the used techniques and to elaborate on open aspects and white spots in this area. We assessed more than 35 approaches spanning from equation-based over various time smoothing to modern learning and location smoothing methods. In addition, different error functions for the evaluation of the approaches as well as publicly available recording tools and datasets are discussed. To conclude, we point out open challenges especially looking in the area of moving mobile network clients. The use of throughput prediction not only enables a more efficient use of the available bandwidth, the techniques shown in this work also result in more robust and stable communication.

Future Work

The transmission performance of a multi-path transmission control protocol (MPTCP) is affected by many parameters, such as path management, congestion control, buffer size, and subflow bandwidth. Most of the previous studies have focused almost exclusively on the improvement of a single parameter, without a holistic view. In this paper, a multi-parameter comprehensive optimized algorithm (MPCOA) is proposed to comprehensively optimize the above parameters. The MPCOA algorithm can find a smaller buffer size and select an appropriate congestion control and path management algorithm on the premise of ensuring better throughput. Experiments in three scenarios show that MPCOA can save buffer space and subflow resources, and achieve a high throughput. Meanwhile, a set of quantitative improvement results given by MPCOA is convenient for us to evaluate the quality of the MPTCP network and provide reference for our ongoing future work.

The Transmission Control Protocol (TCP) is one of the core components of the TCP/IP protocol suite. It has been extensively used for the past three decades (and counting) as the privileged connection-oriented transport mode for many Internet applications, including access to web contents. Nevertheless, experience with TCP can sometimes be rather poor for various reasons which include (but are not limited to) sub-optimized forwarding path capabilities. Because a TCP session can only be established over a single path (by definition), this restriction is not only unable to take into account the dramatic evolution of terminal technologies towards multi-interfaced devices, but also the ability to benefit from several yet potential forwarding paths for the sake of improved Quality of Experience (QoE).

Real Scenario

The fast transformation of the urban centers, pushed by the impacts of climatic changes and the dramatic events of the COVID-19 Pandemic, will profoundly influence our daily mobility. This resulted scenario is expected to favor adopting cleaner and flexible modal solutions centered on bicycles and scooters, especially as last-mile options. However, as the use of bicycles has rapidly increased, cyclists have been subject to adverse conditions that may affect their health and safety when cycling in urban areas. Therefore, whereas cities should implement mechanisms to monitor and evaluate adverse conditions in cycling paths, cyclists should have some effective mechanism to visualize the indirect quality of cycling paths, eventually supporting choosing more appropriate routes. Therefore, this article proposes a comprehensive multi-parameter system based on multiple independent subsystems, covering all phases of data collecting, formatting, transmission, and processing related to the monitoring, evaluating, and visualizing the quality of cycling paths in the perspective of adverse conditions that affect cyclist. The formal interactions of all modules are carefully described, as well as implementation and deployment details. Additionally, a case study is considered for a large city in Brazil, demonstrating how the proposed system can be adopted in a real scenario.

Abstract Background According to the WHO, palliative care (PC) is applicable early in the course of illness together with other curative therapies. Early PC has demonstrated beneficial effects on quality of life and symptom intensity among cancer patients. However, PC is not as early integrated on the care pathway of complex chronic conditions (CCC). This abstract presents barriers and needs identified to effectively implement early PC on CCC performed under the EU-funded InAdvance project (ref.: 825750). Methods Semi-structured interviews were performed with 16 healthcare professionals (HPs) from primary care and hospital settings working with older patients with CCC in Valencia (Spain). Results Interviews reported that main needs identified to provide early PC are: (a) coordinated strategies between multi-setting HPs to an early identification of CCC patients in need of PC; (b) adequate resources to attend patients' PC needs from a holistic view, i.e. psychosocial and spiritual needs; and (c) early integration of basic PC at primary care teams. The main barriers identified were: (a) stereotypes associated to the traditional PC approach; (b) poor knowledge from HPs of the PC holistic approach; and (c) lack of specific protocols or pathways for CCC in need of PC. Conclusions Specific skills and resources are the most relevant needs to effectively provide early PC among patients with CCC. First, it is urgent to demystify the negative culture-related vision of PC that is commonly associated to sedation and last days of a person's life. Also, multidisciplinary HPs require specific training to identify and provide early PC tailored to CCC. And, it is required a strategic and multi-setting organizational approach with fluent information flow and coordinated roles. Key messages Healthcare expenditure would be considerably reduced, especially at hospital and emergency units, with an early identification of patients with CCC in need of PC. Empowering primary HPs in PC would improve the quality of care of patients with CCC.

Transit Agencies

A transit trip involves travel to and from transit stops or stations. The quality of what are commonly known as first and last mile connections (regardless of their length) can have an important impact on transit ridership. Transit agencies throughout the world are developing innovative approaches to improving first and last mile connections, for example, by partnering with ride-hailing and other emerging mobility services. A small but growing number of transit agencies in the U.S. have adopted first and last mile (FLM) plans with the goal of increasing ridership. As this is a relatively new practice by transit agencies, a review of these plans can inform other transit agencies and assist them in preparing their own. Four FLM plans were selected from diverse geographic contexts for review: Los Angeles County Metropolitan Transportation Authority (LA Metro), Riverside (CA) Transit Agency (RTA), and Denver Regional Transit District (RTD), and City of Richmond, CA. Based on the literature, we developed a framework with an emphasis on transportation equity to examine these plans. We identified five common approaches to addressing the FLM issue: spatial gap analysis with a focus on socio-demographics and locational characteristics, incorporation of emerging mobility services, innovative funding approaches for plan implementation, equity and transportation remedies for marginalized communities, and development of pedestrian and bicycle infrastructures surrounding transit stations. Strategies in three of the plans are aligned with regional goals for emissions reductions. LA Metro and Riverside Transit incorporate detailed design guidelines for the improvement of transit stations. As these plans are still relatively new, it will take time to evaluate their impact on ridership and their communities’ overall transit experience.
