Network operator independent resilient overlay for mission critical applications (ROMCA)

This paper proposes a Resilient Overlay for Mission Critical Applications (ROMCA); a novel operator-independent overlay architecture providing a resilient and reliable service across wide-area networks. One feature of ROMCA is that its overlay topology can be altered according to the underlying network conditions. Moreover, resilience is achieved by combining centralized topology construction control and distributed dynamic mapping of paths onto the overlay topology according to network conditions. ROMCA can mitigate the shortcomings of the Internet network infrastructure and provide low recovery times in the event of network failure(s).
