6. Concluding remarks
• Internet technologies can have impact on:
• stakeholders by triggering establishment of new
strategies / business models
• other technologies (functionalities) by triggering
creation of new technologies
• “Tussles friendly” technologies allow for
balanced control between stakeholders
• Better incentives for adoption in the long-run
• … but, requires significant effort from technology
designers for understanding the ecosystem

tussle outcome
• At each stage conflicts of interest (incentives) arise
at the socio-economic layer.
• The combination of actors’ strategies lead to a tussle outcome,
characterized by stakeholders benefits.

Hinweis der Redaktion Tussle analysis helps better understand the interrelations between Future Internet technologies and socio-economics. Its purpose is to study how such stakeholders interact by exploiting Future Internet technologies to advance their economic interests and influence economic outcomes. The presentation will motivate and introduce a generic methodology for tussle analysis by using several case studies and discuss its complexity. Transit & Destination ISPs could forward probing packets preferentially if sample packets were known in advance
