Real Time Adaptive Networking using Programmable 100Gbps NIC on Data Transfer Nodes

High bandwidth, low latency modern-day applications are extremely sensitive to variations in network parameters. In-band Network Telemetry (INT) can help in extracting forwarding plane dynamics of the network element and characterize the service path to make preemptive service modifications. In this demonstration, we showcase a programmable telemetry framework via FPGA based NICs installed in e-science Data Transfer Nodes (DTN) operating over Ciena's Research Network Innovation Platform (CENI). We demonstrate the benefits of this framework in accelerating fault localization mechanisms and implementing corrective actions, in a closed loop with Software Defined Network (SDN) Orchestrators.
