We present a closed-form expression for the minimal delay that is achievable in a setting that combines a buffer and an erasure code, used to mitigate the packet delay variance. The erasure code is modeled according to the recent information-theoretic results on finite block length codes. Evaluations reveal that accurate knowledge of the network parameters is essential for optimal operation. Moreover,...
Parallel transmission is a known technique of transmitting flows over multiple paths from a source towards the same destination. In high-speed Ethernet standards, for instance, large bandwidth flows are inverse-multiplexed into multiple lower-speed flows and transmitted in parallel. However, when flows traverse different paths, attention needs to be paid to the resulting differential delay, which...
Network coding is a highly efficient data dissemination mechanism for wireless networks. Since network coded information can only be recovered after delivering a sufficient number of coded packets, the resulting decoding delay can become problematic for delay-sensitive applications such as real-time media streaming. Motivated by this observation, we consider several algorithms that minimize the decoding...
