Controlled environment / trust assumption Assume the PCN-enabled Internet Region is a controlled environment, i.e. all the interior routers and edge nodes of the region run PCN and trust each other Ring of Edge nodes surround PCN-region ensure packets can’t enter unless part of an admitted flow (for traffic in PCN’s DiffServ class) Trust that all nodes (in PCN-region) run PCN all routers mark packets correctly Is there community consensus on this assumption? largely avoids cheating issues until re-chartering |
