Performance evaluation of secure multipath retransmission mechanism in next generation heterogeneous communication systems

Abstract

With the standardisation of the fifth generation (5G) wireless network interface was established in 3GPP, the features of 5G arouse great interest both in academics and industry, even government. The significant advancements of 5G wireless network technology will make a great increase in the demand for content-rich streaming media services. What's more, many mobile devices with heterogeneous network interfaces (4G, WiFi, and even 5G) connect multiple paths for data delivery simultaneously. Multiple Transmission Control Protocol (MPTCP) is recommended by Internet Engineering Task Force (IETF) to multi-path parallel transmission, which is an important transport layer protocol. Although there are many attractive benefits by using MPTCP for data delivery, it becomes sensitive for MPTCP to network attacks. When a subflow with the MPTCP association suffers from some network attacks (e.g. denial of service attacks), there is undoubted that it will cause large numbers of retransmission data. Unfortunately, the regular MPTCP retransmission mechanisms retransmit data over the same path, which may cause receiver buffer blocking. In this study, the authors propose effective retransmission mechanisms in MPTCP for retransmitting data on a non-congested path. The simulation results show that the proposed retransmission mechanism has better performance than the regular' in the network attacks.

PO-MPTCP: Priorities-Oriented Data Scheduler for Multimedia Multipathing Services

“…According to our previous work [6], we can find that the total Internet traffic is made up by 80%-83% of TCP traffic and 17%-20% of UDP, and the suddenness of the network background traffic increases the difficulty for deployment of MPTCP in the network. For simulating a more real network environment we will configure four TCP traffic generators and one UDP traffic generator in every router to get the 80% of TCP traffic and 20% of UDP traffic.…”

“…Due to the growing demands for bandwidth requirement and transmission rate requirement of real-time streaming applications (i.e., Facebook [2], WeChat [3], YouTube [4], etc. ), traditional single-path Transmission Control Protocol (TCP) [5] cannot utilize the characteristics of the terminals multinetwork interfaces; thus the Internet Engineering Task Force (IETF) proposes Multipath TCP (MPTCP) to be compatible with the current application layer based on traditional TCP [6,7].…”

Performance Evaluation of Multipath TCP Scheduling Algorithms

“…5G is seeking to achieve some key goals like enhanced broadband [1], [2] and ultra-low latency and MPTCP can be closely integrated to with the 5G stack [3], [4] to achieve this aim with regards to dual connectivity.The key motivation behind MPTCP is the trend toward providing trusted and reliable connectivity in the future Internet. The research in this context focuses on faster downloads, lower data transfer costs and seamless switching between different interfaces, particularly the wireless ones such as Wi-Fi and cellular networks [5], [6].…”

Performance analysis of multiple radio-access provision in a multicore-fibre optical fronthaul

“…5G will support different profiles operating at different frequency bands including sub-GHz spectrum bands targeting longrange coverage in rural or remote areas, spectrum bands around 3 GHz to provide connectivity in dense urban areas, and higher frequency bands in the mm-wave range for dedicated highperformance small-cell connectivity (5G NR, new-radio) [2]. This implies that 5G operators are set to deploy cellular networks with a large number of remote radio heads (RRH) on the field, some of them providing joint service of current (5G, 4G) and legacy (3G, 2G) wireless, to optimize the network deployment cost [3]. Compared with 4G radio access, in order to support a wider range of services and scenarios, 5G will need to be more massive and scalable [4].…”

“…MCF comprises multiple cores with sufficiently low crosstalk between neighbouring cores in a single fibre to provide separated spatial paths [12]. Next-generation Mobile Internet Communication will require unlimited and seamless access to Internet information between different network standards [3]. Next-generation networks need to deal with many more base stations, deployed dynamically in heterogeneous multiple radio access technologies (also known as multi-RATs), such as GSM, UMTS or LTE, which need to be flexibly integrated in the network [16].…”
