It seamlessly combines multiple wide-area wireless paths with disparate loss and delay characteristics. PluriBus employs opportunistic erasure coding, a novel technique to use spare capacity along any path to mask losses from end hosts. It sends erasure coded packets only when there is an instantaneous opening in a path&#8217;s spare capacity, so that coded packets do not steal capacity from data packets. Packets are coded using a new erasure code that we have developed to greedily maximize the amount of data recovered with each opportunity to send a coded packet. We have deployed PluriBus on two buses. Our experiments show that it reduces the median flow completion time by a factor of 2.5, compared to an existing method for spreading traffic across multiple paths.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We present PluriBus, a system to provide high performance Internet access on-board moving vehicles.
