Abstract
The Tactile Internet needs to support multiple modalities, including haptic data simultaneously, to enable human and robot interaction in perceived real-time. Compared to video and audio, haptic data streams require an even lower delay and more shallow packet loss, which is a challenge for the underlying networks originally designed to support high bandwidths by having a large queue to buffer packets. This raises the need to study queuing management for different data streams. We examine the performance of CoDel++, which combines the well-known Controlled Delay (CoDel) protocol and Priority Queues. We leverage programmable data planes, which can be programmed with P4. Evaluation results show that CoDel++ produces superior results for high-priority data streams, i.e., reducing latency by at least 60% and packet loss by half compared to individual exploitation of Priority Queuing or CoDel individually.
