Special Issue Information

Dear Colleagues,

Telecommunication networks have for many years been important elements of backbone and access networks. The main objective of this Special Issue is to report recent developments in architectures, protocols, algorithms, and techniques of telecommunication networks, including issues such as design, dimensioning, modeling, control and performance evaluation, and optimization. Authors of both theoretical and application-oriented papers presenting emerging ideas and technologies to solve various unsolved problems and challenges in telecommunications networks are welcome. We invite worldwide researchers and experts to submit high-quality original research papers or critical survey articles.

The topics of interest include but are not limited to:

  • Network architectures, design, and performance evaluation;
  • Technologies used in optimization process of telecommunication networks;
  • Services in optical wire and wireless networks;
  • Performance evaluation of multiservice access nodes in telecommunication networks;
  • Resource management mechanisms for telecommunication networks;
  • Traffic control methods in telecommunication networks;
  • Analytical and simulation models of core and access networks;
  • Design and dimensioning of nodes in backbone networks;
  • Network slicing;
  • Energy-efficient networks.

TCP congestion control adjusts the sending rate in order to protect Internet from the continuous traffic and ensure fair coexistence among multiple flows. Especially, loss-based congestion control algorithms were mainly used, which worked relatively well for past Internet with low bandwidth and small bottleneck buffer size. However, the modern Internet uses considerably more sophisticated network equipment and advanced transmission technologies, and loss-based congestion control can cause performance degradation due to excessive queueing delay and packet loss. Therefore, Google introduced a new congestion control in 2016, Bottleneck Bandwidth Round-trip propagation time (BBR). In contrast with traditional congestion control, BBR tries to operate at the Kleinrock’s optimal operating point, where delivery rate is maximized and latency is minimized. However, when BBR and loss-based congestion control algorithms coexist on the same bottleneck link, most of bottleneck bandwidth is occupied by flows that use a particular algorithm, and excessive packet retransmission can occur. Therefore, this paper proposes a BBR congestion window scaling (BBR-CWS) scheme to improve BBR’s inter-protocol fairness with a loss-based congestion control algorithm. Through Mininet experiment results, we confirmed that fairness between BBR-CWS and CUBIC improved up to 73% and has the value of 0.9 or higher in most bottleneck buffer environments. Moreover, the number of packet retransmissions was reduced by up to 96%, compared to the original BBR. Full article
