Zusammenfassung: | 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. |
