| To meet the increasing demand for high data rates and particularly low delivery delays in heterogeneous communication, we characterized the theoretical limits of the trade-off between high data rate and low delay. Following this characterization, we proposed a number of innovative algorithms combined with adaptive and causal random network coding, that tracks the actual condition of the network to obtain ultra-low reliable communications for data streaming. The proposed communication algorithms integrated with network coding adjust the rate of data transmission in the network across all possible resources while utilizing all the new and existing infrastructure in the network. In this talk, I will review part of the new network coding technologies we developed for low-latency streaming in heterogeneous communications and data systems with different requirements. In particular, I will show fix-to-variable and variable-to-variable solutions based sliding window and layered network coding. |
