The Observer Effect in Computer Networks
Tal Mizrahi, Michael Schapira, Yoram Moses
Network measurement involves an inherent tradeoff between accuracy and overhead; higher accuracy typically comes at the expense of greater measurement overhead (measurement frequen…
Internet Performance in the 2022 Conflict in Ukraine: An Asymmetric Analysis
Tal Mizrahi, Jose Yallouz
On 24 February 2022 Russia invaded Ukraine, starting one of the largest military conflicts in Europe in recent years. In this paper we present preliminary findings about the impact…
Using Internet Measurements to Map the 2022 Ukrainian Refugee Crisis
Tal Mizrahi, Jose Yallouz
The conflict in Ukraine, starting in February 2022, began the largest refugee crisis in decades, with millions of Ukrainian refugees crossing the border to neighboring countries an…
Timing in Software-Defined and Centrally-Managed Networks
Tal Mizrahi, Yoram Moses
The work described in this paper explores the use of time and synchronized clocks in centrally-managed and Software Defined Networks (SDNs). One of the main goals of this work is t…
Time-Multiplexed Parsing in Marking-based Network Telemetry
Alon Riesenberg, Yonnie Kirzon, Michael Bunin +3
Network telemetry is a key capability for managing the health and efficiency of a large-scale network. Alternate Marking Performance Measurement (AM-PM) is a recently introduced ap…
FM-Delta: Fault Management Packet Compression
Tal Mizrahi, Yoram Revah, Yehonathan Refael Kalim +2
Fault Management (FM) is a cardinal feature in communication networks. One of the most common FM approaches is to use periodic keepalive messages. Hence, switches and routers are r…
The Case for Data Plane Timestamping in SDN
Tal Mizrahi, Yoram Moses
This paper presents the case for Data Plane Timestamping (DPT). We argue that in the unique environment of Software-Defined Networks (SDN), attaching a timestamp to the header of a…
OneClock to Rule Them All: Using Time in Networked Applications
Tal Mizrahi, Yoram Moses
This paper introduces OneClock, a generic approach for using time in networked applications. OneClock provides two basic time-triggered primitives: the ability to schedule an opera…
Timed Consistent Network Updates
Tal Mizrahi, Efi Saat, Yoram Moses
Network updates such as policy and routing changes occur frequently in Software Defined Networks (SDN). Updates should be performed consistently, preventing temporary disruptions,…
Time4: Time for SDN
Tal Mizrahi, Yoram Moses
With the rise of Software Defined Networks (SDN), there is growing interest in dynamic and centralized traffic engineering, where decisions about forwarding paths are taken dynamic…
