Access to fiber-optic connectivity in the Internet is traditionally offered either via lit circuits or dark fiber. Economic (capex vs. opex) and operational considerations (latency…
A System for Clock Synchronization in an Internet of Things
Sathiya Kumaran Mani, Ramakrishnan Durairajan, Paul Barford +1
Synchronizing clocks on Internet of Things (IoT) devices is important for applications such as monitoring and real time control. In this paper, we describe a system for clock synch…
In the IP of the Beholder: Strategies for Active IPv6 Topology Discovery
Robert Beverly, Ramakrishnan Durairajan, David Plonka +1
Existing methods for active topology discovery within the IPv6 Internet largely mirror those of IPv4. In light of the large and sparsely populated address space, in conjunction wit…
TimeWeaver: Opportunistic One Way Delay Measurement via NTP
Ramakrishnan Durairajan, Sathiya Kumaran Mani, Paul Barford +2
One-way delay (OWD) between end hosts has important implications for Internet applications, protocols, and measurement-based analyses. We describe a new approach for identifying OW…
