Programmable Event Detection for In-Band Network Telemetry [article]

Jonathan Vestin, Andreas Kassler, Deval Bhamare, Karl-Johan Grinnemo, Jan-Olof Andersson, Gergely Pongracz
2019 arXiv   pre-print
In-Band Network Telemetry (INT) is a novel framework for collecting telemetry items and switch internal state information from the data plane at line rate.  ...  At the network edge, telemetry information is removed and the original packets are forwarded while telemetry reports are sent to a distributed stream processor for further processing by a network monitoring  ...  In-band Network Telemetry (INT) has gained a lot of momentum over the last few years [1] - [5] .  ...

Passive In-band Network Telemetry Systems: The Potential of Programmable Data Plane On Network-wide Telemetry

Pilar Manzanares-Lopez, Juan Pedro Munoz-Gea, Josemaria Malgosa-Sanahuja
2021 IEEE Access  
To improve the INT-based telemetry system, the authors of IntMon propose a high-performance collector called INTCollector [38] that would replace the INT controller services implemented by ONOS controller  ...  As pointed out earlier, although INT monitoring works directly at the data plane, high INT report rates in real-time and complex scenarios imply the need for a high-performance INT collector.  ...  • Use of threshold to identify in-band monitored flows  ...

An Exhaustive Survey on P4 Programmable Data Plane Switches: Taxonomy, Applications, Challenges, and Future Trends [article]

Elie F. Kfoury, Jorge Crichigno, Elias Bou-Harb
2021 arXiv   pre-print
Despite the impressive advantages of programmable data plane switches and their importance in modern networks, the literature has been missing a comprehensive survey.  ...  This open-design paradigm is paving the way for an unprecedented wave of innovation and experimentation by reducing the time of designing, testing, and adopting new protocols; enabling a customized, top-down  ...  FIGURE 7 : 7 In-band Network Telemetry (INT).
