TL;DR: This survey presents many essential research issues about the SDN controller, and especially focus on the control architecture, performance, scalability, placement, interface and security.

TL;DR: This paper model the in-network aggregation problem that is NP-hard in BCube, a novel server-centric networking structure for future data centers, and proposes two approximate methods for building the efficient IRS-based incast aggregation tree and SRS-based shuffle aggregation subgraph, solely based on the labels of their members and the data center topology.

TL;DR: This paper proposes a light-weight and load-aware switch-to-controller selection scheme to cut the long-tail response latency under the simple scenario of homogeneous controllers, and designs a general delay-aware switching scheme to fundamentally cut theLong- tail response latency for the more complicated heterogeneous controller scenario with performance fluctuations.

TL;DR: GRED utilizes the software-defined networking paradigm to support a virtual-space based DHT with only one overlay hop and achieves better load balance among edge servers compared to using Chord, a well-known DHT solution.

TL;DR: A COordinate-based INdexing (COIN) mechanism for the data sharing in edge computing that is effective because any query request from an edge server can be responded when the data has been stored in the edge network and is efficient in both routing path lengths and forwarding table sizes.
