The increasing volume of Internet traffic is pushing the Internet Service Providers to deploy distributed caching services at the network edge, close to the end users, in order to speed up the data retrieval and reduce the bandwidth demands. In parallel, centralized paradigms like Software Defined Networking (SDN) are considered to optimize network management while supporting a variety of network applications like routing, load balancing and caching. In this paper, we extend the SDN control plane to support a novel content caching strategy. We consider a softwarised edge network domain where SDN nodes, augmented with storage capabilities, cache incoming data with the twofold target of limiting the retrieval delay and the inter-domain traffic. The caching decision is taken in a centralized mode by the SDN Controller, according to a newly defined content-driven closeness centrality metric, which identifies the importance of the SDN nodes as cachers based on their proximity to the majority of the clients requesting the most popular contents. Simulation results show the superiority of the solution in terms of higher cache hits and reduced latency, when compared against benchmark caching strategies.

In order to achieve real-time rendering of cloud gaming, a large amount of computing resources of graphics processing units (GPU) are required. In this paper, we propose a multi-GPU parallel pipeline rendering approach that makes full use the computing power of multiple GPUs to accelerate real-time ray tracing rendering effectively. This approach enables heterogeneous GPUs to render the same frame cooperatively through a dynamic splitting frame load balancing scheme, and ensures that each GPU is assigned with the suitable size of splitting frame based on its rendering ability. A fine-grained parallel pipeline method divides the process of rendering into more detailed steps that enable multiple frames to be rendered in parallel, which improves the utilization of each step and speeds up the output of frames. With the experiments on various dynamic scenes, the results show that the number of frames per second (FPS) of the multi-GPU system composed of two GPUs is 2.2 times higher than that of the single GPU system, while the multi-GPU system composed of three GPUs has increased to 3.3 times.
