The document discusses digital ecosystems and proposes a solution for managing transactions within a digital business ecosystem network. It suggests using software agents to gather and store local knowledge, make external links, manage content, and process business activities and transactions. This would help create a connected network between service providers and small-to-medium enterprises (SMEs) in a way that is resistant to failures and able to handle the dynamic nature of content, links, and transactions over time.

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?

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
