Revisiting Resource Pooling: The Case for In-Network Resource Sharing
Lorenzo Saino, University College London
In this talk I will present our recent HotNets paper, in which we propose to extend the resource pooling principle to also take advantage of in-network resources, in terms of multiplicity of available sub-paths and in-network caching space. In particular, we question the widely adopted view of in-network caches acting as temporary storage for the most popular content in Information-Centric Networks. Instead, we propose that in-network storage is used as a place of temporary custody for incoming content in a store-and-forward manner. Given this functionality of in-network storage, senders push content into the network in an open-loop manner to take advantage of underutilised links. When content hits the bottleneck link it gets re-routed through alternative uncongested paths. If alternative paths do not exist, incoming content is temporarily stored in in-network caches, while the system enters a closed-loop, back-pressure mode of operation to avoid congestive collapse.
