Emerging with unprecedented features of programmable network management at a centralized controller for network technology in recent years, Software-Defined Networking (SDN) has promptly received much attention from both industry and academic research. However, to provide security and scalability of network, a single centralized controller gives way to a distributed controllers architecture. Unfortunately, this architecture lacks an effective scheme to dispatch load among controllers. Thus, we present a mechanism of load balancing and failure recovery for SDN distributed controllers, named Aloba. It monitors the imbalance state of entire the network and resolves the failure of centralized making decision of current solutions. The mechanism also reduces the overhead of communication among controllers while choosing and migrating burden of network into suitable target by using both strategies of anti-load fluctuation and flexible data collection.

Medichain: A multi-chain based system for managing prescription medications using Zero Knowledge Proofs

The abuse of prescription medications has become a severe public health crisis fueled by limited coordination and oversight across healthcare systems. Current frameworks lack interoperability between doctors, pharmacies, and regulators, enabling abusive practices like doctor shopping and pharmacy hopping. To address these issues, this research proposes Medichain, a novel multichain-based...
