Multi-ring topology

• Based on rings, inherits characteristics:
  • Throughput does not dependent of the number of nodes
  • Decentralized management
    
    
• Inner rings provide shortcuts to all ring sections
  
  
• An inner ring can have further inner rings

• Formation of inner rings exploits peer heterogeneity (peers have diverse capabilities)
  Inner ring peers election: peers that have the highest sending bandwidth among their neighbors of distance d
  d: distance between two inner ring nodes
  
  
• Inner ring peers are balanced in outer rings:
  swapping positions with an outer ring neighbor if needed
