“…Shen et al . [11] presented an improved retransmission policy ( RTX‐CR ), which chooses the retransmission path by considering congestion window and RTT for reducing rbuf blocking. However, the above works seldom consider network security, which plays an important role in deploying 5G and MPTCP‐based streaming media services.…”

“…Among them, RTX‐CWND and RTX‐SSTHRESH are recommended retransmission mechanisms in CMT‐SCTP according to the RFC4460. Moreover, RTX‐CWND is recommended as the default retransmission mechanism, which can provide the best performance [11]. Motivated by the fact that an intelligent retransmission mechanism is very important for deploying 5G and MPTCP‐based streaming media services, the paper applies the ideas of RTX‐CWND and RTX‐SSTHRESH to MPTCP by selecting the optimal transmission quality path (the largest cwnd or the largest sshresh value) to retransmit the packets.…”

“…In the light of RFC4460, there are only RTX‐CWND and RTX‐SSHRESH recommended as CMT‐SCTP retransmission mechanisms, the others just meet the experimental requirements.

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.

Stream control transmission protocol (SCTP) is a transport layer protocol, which is efficient, reliable, and connection-oriented as compared to transmission control protocol (TCP) and user datagram protocol (UDP). Additionally, SCTP has more innovative features like multihoming, multistreaming and unordered delivery. With multihoming, SCTP establishes multiple paths between a sender and receiver. However, it only uses the primary path for data transmission and the secondary path (or paths) for fault tolerance. Concurrent multipath transfer extension of SCTP (CMT-SCTP) allows a sender to transmit data in parallel over multiple paths, which increases the overall transmission throughput. Parallel data transmission is beneficial for higher data rates. Parallel transmission or connection is also good in services such as video streaming where if one connection is occupied with errors the transmission continues on alternate links. With parallel transmission, the unordered data packets arrival is very common at receiver. The receiver has to wait until the missing data packets arrive, causing performance degradation while using CMT-SCTP. In order to reduce the transmission delay at the receiver, CMT-SCTP uses intelligent retransmission polices to immediately retransmit the missing packets. The retransmission policies used by CMT-SCTP are RTX-SSTHRESH, RTX-LOSSRATE and RTX-CWND. The main objective of this paper is the performance analysis of the retransmission policies. This paper evaluates RTX-SSTHRESH, RTX-LOSSRATE and RTX-CWND. Simulations are performed on the Network Simulator 2. In the simulations with various scenarios and parameters, it is observed that the RTX-LOSSRATE is a suitable policy.
