OpenFlow enabled networks split and separate the data and control planes of traditional networks. This design commodifies network switches and enables centralized control of the network. Control decisions are made by an OpenFlow controller, and locally cached by switches, as directed by controllers. This can significantly impact the forwarding delay incurred by packets in switches, because controllers...
In this work-in-progress paper, we present a network coding scheme based on random linear coding (RLC), named cumulative RLC. Cumulative RLC applies RLC in a cumulative manner such that the end-to-end delay is minimized and it can be used for real-time one-to-many video distribution over wireless networks. The proposed cumulative RLC is well-suited especially for media applications with low-latency...
This paper investigates several problems associated with optical multicast routing and wavelength assignment in sparse-splitting optical networks for interactive real-time media distribution. Unfortunately, the constrained multicast routing with optimized wavelength assignment leads to NP-complete condition. Thus, in this paper, a virtual-node-based multicast routing algorithm is first proposed to...
