| Description | The active network approach allows an individual user to inject customized programs into active nodes in the network, usually called programmable/active nodes, and thus process data in the network as it passes through. As the speeds of network links still increase, and subsequently, the applications' demands for the network bandwidth increase as well, a single active node is infeasible to process such high-bandwidth user data in real-time, since the processing may be fairly complex (e.g., high-quality video down-sampling for videoconference clients with low bandwidth connectivity). The paper presents the architecture of DiProNN node---the VM-based Distributed Programmable Network Node, that improves the scalability of such an active system with respect to number of active programs simultaneously running on the node and with respect to the bandwidth of each passing stream processed. Since the node is primarily meant to perform stream processing, and to make programming of stream processing applications for DiProNN node easier, we also propose suitable modular programming model. To make DiProNN programming more comfortable, the model takes advantages of DiProNN virtualization---using standard network services the DiProNN node interconnects standalone special-purpose active programs into an abstractly described complex processing system. |
