“…For instance, the transcoding function is a difficult procedure that P4 does not natively implement. To address this issue, P4 extensions may be added in two ways: by introducing new primitives or by using extern instances [9]. In our implementation, we used a free software transcoder written in C as an extern function that we instantiated in the switch core through a P4 program.…”

Applications such as holographic concerts are now emerging. However, their provisioning remains highly challenging. Requirements such as high bandwidth and ultra-low latency are still very challenging for the current network infrastructure. In-network computing (INC) is an emerging paradigm that enables the distribution of computing tasks across the network instead of computing on servers outside the network. It aims at tackling these two challenges. This article advocates the use of the INC paradigm to tackle holographic applications' high bandwidth and low latency challenges instead of the edge computing paradigm that has been used so far. Slicing brings flexibility to next-generation networks by enabling the deployment of applications/verticals with different requirements on the same network infrastructure. We propose an architecture that enables the provisioning of INC-enabled slices for holographic-type application deployment. The architecture is validated through a proof of concept and extensive simulations. Our experimental results show that INC significantly outperforms edge computing when it comes to these two key challenges. In addition, low jitter was maintained to preserve the hologram's stability.

Network measurement technology is the basis of the monitoring network devices, link and flow running state and flow behavior model. The current network measurement mainly adopts the method of active measurement, in other words, managers use injection flow probe to measure the network actively, but this method can increase the network flow and influence the state of the network and the network load. To solve this problem, this paper proposes a method that is fine-grained network traffic parameter measurement based on in-band network telemetry technology. Software defined network architecture and the principle of data plane programmable technology is introduced first, and then the process of using in-band network telemetry to obtain network traffic parameters is described in detail. Finally, this paper simulates the network environment and attack environment in the simulation environment to obtain the data set required for the experiment, and the results of the data set are analyzed to verify the effectiveness of this method based on in-band network telemetry technology.

“…Behavioral-Model version 2 (BMv2) devices [10] or SUME NetFGPAs [11]). The use of non-standard P4 externs is not uncommon [12] and comes from the impossibility of modifying the P4 forwarding tables while processing packets in the P4 pipeline, replacing the need of relying on the SDN controller for the injection of new rules. Unfortunately, being non-standard extensions of the language, a widespread adoption of extern-based solutions is not achievable.…”
