Network planning is critical to the performance, reliability and cost of web services. This
problem is typically formulated as an Integer Linear Programming (ILP) problem. Today's …

Networks are expected to provide reliable performance under a wide range of operating
conditions, but existing traffic engineering (TE) solutions optimize for performance or …

To keep up with the continuous growth in demand, cloud providers spend millions of dollars
augmenting the capacity of their wide-area backbones and devote significant effort to …

Many enterprises today manage traffic on their wide-area networks using software-defined
traffic engineering schemes, which scale poorly with network size; the solver runtimes and …

This paper presents **gubang, the first reported system for checking network traffic load
properties (eg, if any link's utilization would exceed 80% during a network change) in a …

Ensuring the correctness of programmable data planes is important. Testing offers
comprehensive correctness checking, including detecting both code bugs and non-code …

We study two-stage adjustable robust linear programming in which the right-hand sides are
uncertain and belong to a convex, compact uncertainty set. This problem is NP-hard, and the …

In this work we propose Shoofly, a network design tool that minimizes hardware costs of
provisioning long-haul capacity by optically bypassing network hops where conversion of …

Many optical circuit switched data center networks (DCN) have been proposed in the last
decade to attain higher capacity and topology reconfigurability, though commercial adoption …

This paper presents YU, the first verification system for checking traffic load properties under
arbitrary failure scenarios that can scale to production Wide Area Networks (WANs). Building …
