Department: Computer Science

COMP4177: NETWORKS AND THEIR STRUCTURE

Type Open Level 4 Credits 10 Availability Available in 2024/2025 Module Cap None. Location Durham

Prerequisites

  • COMP2181 Theory of Computation

Corequisites

  • None

Excluded Combination of Modules

  • None

Aims

  • To design structured networks to provide the communications fabric of distributed-memory multi-processors, networks-on-chips and data centre networks.
  • To introduce the theoretical and practical tools needed to analyse social and technological networks.

Content

  • Core aspects of interconnection networks: topology; routing; switching; flow control; packets; technology.
  • Graph theory: degree; cuts; bisections; paths; diameter; embeddings; automorphisms; symmetry.
  • Topologies: hypercubes; tori; k-ary n-cubes; cube-connected cycles.
  • Performance: traffic patterns; throughput; latency; path diversity; packaging; routing algorithms.
  • Modelling networks to make comparisons and predictions: random graphs; Milgram's small world experiment; Watts-Strogatz model; Kleinberg model.
  • Centrality measures: finding influential nodes in networks; using centrality measures to understand the community structure of networks.
  • Epidemics: how contagions spread in networks; models of diffusion; SIR model; epidemic threshold; SIS model.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

  • Lectures enable the students to learn new material and engage in discussion.
  • Formative and summative assessments assess the application of methods and techniques.
