Given a SDN topology, how many controllers are needed and where should they go?

Author: Mamushiane, Lusani ; Mwangama, J ; Lysko, Albert A Date: Nov 2018 Software Defined Networking (SDN) presents a paradigm shift in network management and configuration. The idea of having an externalized control plane opens many unanswered questions regarding scalability, fault tolerance and performance of ... Read more
HP: A light-weight hybrid algorithm for accurate data partitioning

Author: Olukanmi, P ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Aug 2020 This paper introduces a hybridization of the k-means and k-medoids paradigms. The new algorithms is named HP (hybrid partitioning) algorithm. Specifically, we improve on a recently developed scalable version of k-means (k-means-lite), by ... Read more
Optimum placement of SDN controllers in African backbones: SANREN and ZAMREN as a case study

Author: Mamushiane, Lusani ; Mwangama, J ; Lysko, Albert A Date: Sep 2018 Software Defined Networking (SDN) has emerged as a potential solution to the ICT inequality challenge in emerging markets. This technology promises to revolutionize the telecommunications industry by introducing decoupled architectures to ... Read more
PAM-lite: Fast and accurate k-medoids clustering for massive datasets

Author: Olukanmi, PO ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Jan 2019 The Partitioning Around Medoids (PAM) clustering algorithm is well-known for its robustness and accuracy, but it is computationally expensive. This paper proposes a fast and accurate version, named PAM-lite. Like CLARA which also addresses ... Read more
Performance evaluation of sampling-based large-scale clustering algorithms

Author: Olukanmi, PO ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Jan 2019 Using benchmark datasets, we study the performances of three efficient clustering algorithms which find cluster centers using a fixed number of random samples. The algorithms are also compared with two other (well-known) algorithms, namely ... Read more
