Multipath TCP (MPTCP) has gained great attention by the researchers and network application developers due to its features providing better bandwidth utilization and higher reliability recently. Utilizing MPTCP in the datacenters provides performance gain to the applications. If the underlying network has Software Defined Networking (SDN) architecture, the routing of the MPTCP subflows can be specialized...
Dynamic Adaptive HTTP Streaming (DASH) is a popular MPEG standard. In DASH systems, the clients adapt quality based on the observed network and internal parameters in order to achieve high Quality of Experience (QoE). The throughput of Internet applications can be increased if the underlying transport protocol utilizes the network conditions by using multiple end-to-end connections. MPTCP is a recent...
Software-defined Networking (SDN) is a promising network architecture for future internet applications by seperating the control and data layer of computer networks. On the other hand, Application Layer Traffic Optimization (ALTO) protocol provides ISP-friendly communication by provisioning network related information to the applications. In this paper, we propose a method for selecting appropriate...
Software Defined Networks (SDN) is a new technology providing a programmable network by separating control and data planes of computer networks. SDN technology can provide an increase in the performance of Internet applications by implementing routing approaches specific to such applications. In this paper, we propose a server and end-to-end path selection approach for a content distribution network...
Software Defined Networking (SDN) is a promising technology for future internet applications through decoupling the data and control planes of computer networks. Enabling the development of application specific routing algorithms, the separation fosters the performance of internet applications. On the other hand, Application Layer Traffic Optimization (ALTO) provides network related information such...
Today, the most of the video streaming system provides quality adaptation and prefers to send their packets over HTTP. MPEG group has standardized Dynamic Adaptive HTTP Streaming (DASH) regarding this tendency on the adaptive HTTP streaming. Besides providing quality adaptation with a non-scalable codec, DASH standard also allows Scalable Video Coding (SVC) to adapt quality. Software Defined Networks...
In this paper we propose an SDN based dynamic path selection for HTTP-based video streaming. MPEG-DASH is a recently proposed standard allowing rate adaptation over HTTP. On the other hand, Software Defined Networking (SDN) is a new network architecture, which allows determining routes of packet flows by an external controller software. In this study we develop an optimization model aiming to obtain...
In this paper we propose an inference based packet recovery technique which considers past scores indicating retransmission success of the peers. Past scores are calculated by considering several parameters such as requested packets availability and round trip time. The importance of packets to be retransmitted is also considered in the proposed model. In order to obtain comparable results, we also...
