Demo abstract: Stemflow: Inter-datacenter overlay as a service
Shuhao Liu, Baochun Li · 2017
Thanks to the abundant available bandwidth and multiple paths on wide-area links that interconnect datacenters on major cloud platforms, it is conceivable that bandwidth-intensive applications may improve their performance by relaying their traffic through such an inter-datacenter network. We propose Stemflow, a new systems framework that provides Inter-Datacenter Overlay as a Service. It is provided as a turn-key solution for applications to conveniently and transparently tap into the available bandwidth resources across datacenters in the cloud, with internal optimizations on the performance of data delivery. Internally, we have implemented Stemflow as a software-defined overlay. We present two interactive cloud applications built upon Stemflow - live video broadcast and instant messaging - to demonstrate the ease of development and the performance gains by using Stemflow.
