CLINT: Controller-Assisted Lightweight In-Band Network Telemetry
2024 - IEEE Access, Vol. 12
The increasing need for high-precision monitoring and network-wide observability has spurred significant interest in In-Band Network Telemetry (INT), which empowers the collection of monitoring data directly from the dataplane, thus, alleviating the various shortcomings of passive monitoring…
Deterministic and Probabilistic P4-Enabled Lightweight In-Band Network Telemetry
2023 IEEE Transactions on Network and Service Management
In-band network telemetry (INT), empowered by programmable dataplanes such as P4, comprises a viable approach to network monitoring and telemetry analysis. However, P4-INT as well as other existing frameworks for INT yield a substantial transmission overhead, which grows linearly with the number of…
