QRON: QoS-aware routing in overlay networks

摘要: Recently, many overlay applications have emerged in the Internet. Currently, each of these requires their proprietary functionality support. A general unified framework may be a desirable alternative to application-specific overlays. We introduce concept brokers (OBs). assume that autonomous system Internet has one or more OBs. These OBs cooperate with other form an service network (OSN) and provide support for applications, such as resource allocation negotiation, routing, topology discovery, functionalities. The scope our effort is quality-of-service (QoS) networks. Our primary focus on design QoS-aware routing protocols networks (QRONs). goal QRON find QoS-satisfied path, while trying balance traffic among links OSN. subset OBs, connected by paths, can application specific application. proposed algorithm adopts hierarchical methodology enhances its scalability. analyze two different types path selection algorithms. simulated based transit-stub topologies produced GT-ITM. Simulation results show algorithms perform well providing service.
