Network Neutrality Inference

Aikaterini Argyraki, Ovidiu Sebastian Mara, Zhiyong Zhang

When can we reason about the neutrality of a network based on external observations? We prove conditions under which it is possible to (a) detect neutrality violations and (b) localize them to specific links, based on external observations. Our insight is ...

Performance Contracts for Software Network Functions

George Candea, Aikaterini Argyraki, Solal Vincenzo Pirelli, Luis David Figueiredo Mascarenhas Moreira Pedrosa, Arseniy Zaostrovnykh, Rishabh Ramesh Iyer

Software network functions (NFs), or middleboxes, promise flexibility and easy deployment of network services but face the serious challenge of unexpected performance behaviour. We propose the notion of a performance contract, a construct formulated in ter ...

Software Dataplane Verification

Aikaterini Argyraki, Mihai Dobrescu

The industry is in the mood for programmable networks, where an operator can dynamically deploy network functions on network devices, akin to how one deploys virtual machines on physical machines in a cloud environment. Such flexibility brings along the th ...

Toward a Verifiable Software Dataplane

Aikaterini Argyraki, Mihai Dobrescu

Software dataplanes are emerging as an alternative to traditional hardware switches and routers, promising programmability and short time to market. These advantages are set against the concern of introducing buggy or under-performing code into the network ...

Flow/Path Performance Consistency

Seyed Mahdi Hosseini, Aikaterini Argyraki, Pavlos Nikolopoulos, Georgia Fragkouli

We explore a new network-performance metric: flow/path consistency, which captures whether the end-to-end performance of the flows that traverse a network is consistent with the aggregate performance of the network's elements. We propose a formal definitio ...
