摘要：The publish/subscribe paradigm is an appealing solution as messaging middleware because it offers the time, space, and synchronization decoupling properties that distributed applications such as online gaming, messaging, social networking, and business intelligence require. These applications are typically characterized by a large number of participants scattered across the world that communicate by exchanging messages on a wide area network (WAN), such as the Internet. However, while this kind of middleware fits the generic asynchrony and scalability requirements of large scale complex critical infrastructures (LCCIs), like air traffic control (ATC) systems, it completely or partially lacks the support of quality-of-service (QoS) guarantees. The Proposed System includes P-Coding: a light weight security applied to network coding and a mechanism to choose gossip partners during the recovery phase of the protocol. It uses a polarized gossip, in which a subscriber assigns a weight to a subset of other subscribers. The system has two different methods for assigning the weight. First one is based on the current network status. The second is based on the position of the nodes in the overlay network.
