AS-cast: Lock Down the Traffic of Decentralized Content Indexing at the Edge

Although the holy grail to store and manipulate data in Edge infrastructures is yet be found, state-of-the-art approaches demonstrated relevance of replication strategies that bring content closer consumers: The latter enjoy better response time while volume passing through network decreases overall. Unfortunately, locating closest replica a specific requires indexing every live along with its location. Relying on remote services for such aim enters contradiction properties as replicas may effectively take more than actually downloading content. At opposite, maintaining an index at node would prove overly costly terms memory traffic. In this paper, we propose decentralized implementation called AS-cast. Using AS-cast, only indexes replica; all connected nodes similar compose partition. AS-cast (i) efficient, it uses partitions lock down traffic generated by operations relevant nodes, (ii) guarantees eventually acknowledges despite concurrent operations. Our prototype, implemented PeerSim, shows scales well messages termination time. As such, can constitute novel building block geo-distributed need efficient resource sharing vicinity regions.
