An SDN-Based Transmission Protocol with In-Path Packet Caching and Retransmission

Abstract

In this paper, a comprehensive software-defined networking (SDN) based transmission protocol (SDTP) is presented for fifth generation (5G) communication networks, where an SDN controller gathers network state information from the physical network to improve data transmission efficiency between end hosts, with in-path packet retransmission. In the SDTP, we first develop a new two-way handshake mechanism for connection establishment between a pair of end host. With the aid of SDN control module, signaling exchanges for establishing E2E connections are migrated to the control plane to improve resource utilization in the data plane. A new SDTP packet header format is designed to support efficient data transmission with in-path packet caching and packet retransmission. Based on the new data packet format, a novel in-path receiver-based packet loss detection and caching-based packet retransmission scheme is proposed to achieve in-path fast recovery of lost packets. Extensive simulation results are presented to validate the effectiveness of the proposed protocol in terms of low connection establishment delay and low end-to-end packet transmission delay.

Countering crossfire DDoS attacks through moving target defense in SDN networks using OpenFlow traffic modification

“…The packet drop rate for both the techniques is calculated using the method defined in Reference 42 and verified that our values lie within the acceptable range which is 0%-5%. 43 Figure 13 depicts that through IP address redirection technique 98.5% packets from the attacker network are successfully redirected towards the shadow network/honeynet while only 1.5% packets are dropped and could not reach the shadow network/honeynet. Overall the IP address redirection technique was proved to be successful against attackers.…”

DRTP: A Disruption Resilient Hop-by-Hop Transport Protocol for Synchrophasors Measurement in Electric Transmission Grids

“…Each hop requests its upstream ones to feedback the cached packets. J. Chen proposed the adaptive transmission protocol (SDATP) [20] [21]. In the SDATP, each in-path switch retransmits the lost packets detected according to the packet disordering and interarrival time from its upstream neighbored one.…”

“…To reduce the EEFR, the current promising approach is hop-by-hop retransmission control for lost packets adopting in-path caching [18] [19] [20] [21] [22]. Recent studies have demonstrated that this type of control can outperform existing end-to-end transport protocols [20] [22].…”
