26. Super peers and permanent nodes super peers are expensive nodes with costly maintenance requirements Who is going to provide such nodes? during peak time the pressure of high traffic can result in a bottleneck on super peer nodes How they cope with the dynamic network structure? processing redundant data and producing overheads waste at off-peak times of the network while they will be continuously under pressure at peak time while the network grows How regular cost increased can be justified?
27. PERMANENT CLUSTERS & VIRTUAL SUPER PEERS Good connectivity Spreading Traffic Clustering stability and local storage Network Dynamicity on VSPs
29. Achilles heel of the network high dependency on a few number of nodes vulnerable on any smart attack on hubs As the fragmentation on the network (creating islands in the network) costly to repair (de-fragmentation) inconsistency of such a model with the dynamicity of a digital ecosystem SMEs may not provide stable and permanent nodes for hubs at all This means fragmentation even without any external attack or physical failures
