Verifiable Network-Performance Measurements, Katerina Argyraki, Petros Maniatis, and Ankit Singla. This work shows how the Internet network layer can provide an accurate, lie-resistant, and lightweight mechanism that gives information on the fate of transported traffic. It presents Network Confessional, a system and protocol that enables network domains to export information on their loss and delay performance. This system guarantees accurate and trustworthy information while minimizing in-network monitoring state, in particular, it requires no per-packet, per-flow, or per-path monitoring state inside the network. In CoNEXT 2010.
Loss and Delay Accountability for the Internet, Katerina Argyraki, Petros Maniatis, Olga Irzak, Ashish Subramanian, and Scott Shenker. This work presents AudIt, an explicit “accountability interface,” through which network domains can export information on their loss and delay performance with respect to transported TCP traffic. In ICNP 2007.
Providing Packet Obituaries, Katerina Argyraki, Petros Maniatis, David R. Cheriton, and Scott Shenker. This work introduces the idea of network domains providing feedback on the traffic they forward and describes a preliminary mechanism for informing traffic sources where their packets are getting lost. In the HotNets 2004 workshop.
A more theoretical perspective on accountability. Uses tools from cryptography to prove the minimum set of requirements for providing accountability under the broadest threat model.
In PeerReview, members of a distributed system hold each other accountable for Byzantine behavior by replaying secure logs of exchanged messages.
An economic analysis of ISP business shows that, without accountability, innovation and competition in the Internet are impossible.
Availability-oriented path selection relies on accurate information on the performance of transit networks to optimize route selection in multi-path routing.
