Multipath transport control protocol for 5G mobile augmented reality networks

SummaryThe performance of backhaul networks is the major concern for internet service providers, cloud service providers, and data centers for redundancy and reliability. With the integration of new data communication technologies, the system should be more smart and intelligent to handle data traffic coming from new networks like 5G. This new 5G standard provides connectivity among devices where all the traffic is handled by backbone and backhaul networks. The devices and nodes need multiple interfaces, but the TCP/IP standard uses a single path per connection for data communication. This limitation leads to the degradation of network performance and communication failures. There is a need to enhance data throughput and performance by using available paths and interfaces. Multipath Transport Control Protocol (MTCP) is one of the advanced extension of the TCP/IP standard for using available interfaces. This paper proposed an MTCP based infrastructure for 5G networks to handle all the coming data from these networks and provide fast reliable data handling. The proposed infrastructure is evaluated in simulation to check its performance with existing standards. The results indicate that the proposed infrastructure is minimizing the convergence time in case of any failure in the main path.

Stochastic Optimization of Multipath TCP for Energy Minimization and Network Stability over Heterogeneous Wireless Network

Multipath Transport Control Protocol (MPTCP) is a transport layer protocol that enables multiple TCP connections across various paths. Due to path heterogeneity, it incurs more energy in a multipath wireless network. Recent work presents a set of approaches described in the literature to support systems for energy consumption in terms of their performance, objectives and address issues based on their design goals. The existing solutions mainly focused on the primary system model but did not discourse the overall system performance. Therefore, this paper capitalized a novel stochastically multipath scheduling scheme for data and path capacity variations. The scheduling problem formulated over MPTCP as a stochastic optimization, whose objective is to maximize the average throughput, avoid network congestion, and makes the system more stable with greater energy efficiency. To design an online algorithm that solves the formulated problem over the time slots by considering its min-drift-plus penalty form. The proposed solution was examined under extensive simulations to evaluate the anticipated stochastic optimized MPTCP (so-MPTCP) outcome and compared it with the base MPTCP and the energy-efficient MPTCP (eMPTCP) protocols. Simulation results justify the proposed algorithm''s credibility by achieving remarkable improvements, higher throughput, reduced energy costs, and lower-end to end delay.

An implementation of multipath TCP in ns3

The Multipath Transport Control Protocol (MPTCP) is undergoing a rapid deployment after a recent and quick standardization. MPTCP allows a network node to use multiple network interfaces and IP paths concurrently, which can lead to several advantages for the user in terms of performance and reliability. In this paper, we describe an MPTCP implementation in the Network Simulator 3 (ns3), comparing it with both the Linux implementation and previous ns3 implementations. We show that it is compatible with the Linux implementation and that it has a desirable similar behavior in traffic handling. Our goal is to allow researchers develop and evaluate new features of MPTCP using our simulator in a much faster way than they would with a kernel implementation, hence boosting MPTCP research.

An evolvable, scalable, and resilient control channel for software defined wireless access networks

This paper presents a novel multipath communication-based OpenFlow channel for Software Defined Wireless Access Networks (SDWANs), namely mOpenFlow. The advantageous features of mOpenFlow include the following: (i) resilience and scalability in wireless environments, (ii) evolvability of the existing access networks and the OpenFlow standard, (iii) a novel network calculus-based model for performance analysis of mOpenFlow. By leveraging the multipath communication for conveying OpenFlow traffic, mOpenFlow enhances both robustness (i.e., resilience) and throughput (i.e., scalability) of the control channel. To achieve the evolvability, mOpenFlow adopts the multipath transport control protocol, which conforms to SDWANs and the OpenFlow standard. We evaluate mOpenFlow in an emulated SDWAN in relation to the standard channel. The results show that mOpenFlow outperforms the standard channel, both in terms of robustness and scalability. Additionally, the numerical results indicate that the model provides a fast and reliable way for analyzing the end-to-end delay on mOpenFlow.

Goodput improvement for multipath transport control protocol in cooperative relay‐based wireless networks

Multipath transport control protocol (MPTCP) standardised by Internet Engineering Task Force offers a promising solution to support simultaneous delivery of transport control protocol packets over multiple interfaces of multi-radio mobile devices. Even when there is no multiple access coverage, it is still possible to enable multipath transmission by involving mobile devices in vicinity as cooperative relays. However, the available bandwidth provided by relays can be highly varying because of wireless channel fading or dynamic local traffic load. Although MPTCP can pool the available bandwidths of multiple paths, it is challenging to address the dynamics of the cooperative wireless network and ensure a stable performance. In this study, the authors extend MPTCP for the long-term evolution network with cooperative relays by an integrated solution in three aspects, namely, subset ‘sum-based relay selection’, ‘adaptive congestion control’ and ‘differentiated packet forwarding’. Extensive simulations in NS-3 show that the proposed modules can achieve a stable aggregate throughput by engaging a small number of relays and significantly improve the goodput in various scenarios.

MPTCP Congestion Control Algorithm Based on the Fairness of Bottleneck

Mobile devices equipped with multiple network interfaces can increase their throughput by making use of parallel transmissions over multiple paths and bandwidth aggregation, enabled by the multipath Transport Control Protocol (MPTCP). However, the existing MPTCP congestion control algorithm adopt a relatively strict definition of the fairness, although to some extent could ensure the fairness of traditional TCP connections, but the total throughput of MPTCP will be limited, which can not make full use of network resources. To solve this problem, this paper propose a congestion control algorithm (FBCC) based on the fairness of bottleneck. The core idea of FBCC is to set up individual fairness factor for each shared bottleneck. NS3 simulation results show that FBCC algorithm not only solves the problem of fairness, but also effectively improve the total throughput of MPTCP connection.
