VeriFlow: verifying network-wide invariants in real time
TL;DR: VeriFlow as discussed by the authors is a layer between a software-defined networking controller and network devices that checks for network-wide invariant violations dynamically as each forwarding rule is inserted, modified or deleted.

Can Accurate Predictions Improve Video Streaming in Cellular Networks
Xuan Kelvin Zou,Jeffrey Erman,Vijay Gopalakrishnan,Emir Halepovic,Rittwik Jana,Xin Jin,Jennifer Rexford,Rakesh K. Sinha +7 more
TL;DR: It is believed that cellular operators and content providers can tremendously improve video QoE by predicting available bandwidth and sharing it through APIs.
Proceedings ArticleDOI
An assertion language for debugging SDN applications
TL;DR: An assertion language to support verifying and debugging SDN applications with dynamically changing verification conditions, and proposes an incremental data structure together with an underlying verification engine to avoid naively re-verifying the entire data plane as these verification conditions change.
Proceedings ArticleDOI
Dynamic Service Chaining with Dysco
TL;DR: It is argued that a session-level protocol is a fundamentally better approach to traffic steering, while naturally supporting host mobility and multihoming in an integrated fashion.

Rittwik Jana,Jeffrey Erman,Vijay Gopalakrishnan,Emir Halepovic,Rakesh K. Sinha,Xuan Kelvin Zou +5 more
TL;DR: In this paper, the authors proposed a method for determining bit rates for portions of media content according to the predicted available bandwidths and according to buffer occupancy during streaming of the media content to the end user device over a wireless network.
