> Motivation: Distributed Machine Learning across the Internet is critical for training models with private and sensitive data. However, the slow speed of wide-area-network poses a bottleneck in model synchronization. Strato aims to solve this problem by creating a software-defined network that is optimized to speed up the data pattern of intern-DC ML training.

> Exceptional Performance: Leveraging Rust's powerful zero-cost abstraction and ownsership model, Strato is capable of achieving multi-Gbps throughput on mid-tier cloud vCPUs. The performance is further augmented with coroutines and async I/O, thanks to Rust's powerful tokio runtime. Fairness in ensured in packet processing between coroutines to cater to the needs of distributed communciation algorithms such as RingAllReduce.

> Core Challenges Solved: TE problems are formulated as constrained optimization problems. However, training a neural network to approximate the optimal solution while respecting the contraints is inherently difficult. DeepTE solves this problem with the novel mechanism Gradient Descent-based Feasibility Projection that guarantees the solution meets contraints within finite iterations.

> Motivation: ML models can be vulnerable to various adversarial attacks algorithms. However, there is no standard benchmarking tool for comparing the performance of these different attack algorithms. DeepPen aims to solve this problem by providing a web application where researchers can upload their attack algorithms and compare their performance against other algorithms.
