Cloud-edge applications often require data flows to meet stringent latency requirements, ensuring punctual IP packet delivery within specific time windows. To this end, the guaranteed Latency Based Forwarding (gLBF) approach features per-hop bounded delays to meet the target latency requirements of data flows based on end-to-end application needs. This article introduces a Prolog-based specification of gLBF for path selection and delay configuration. Our prototype determines paths and delays to meet data flow latency targets, offering a concise and extendable solution to the considered problem. We illustrate the scalability of our approach on real and random network topologies, with up to 1000 nodes and flows to be placed.

Abstract
Cloud-edge applications often require data flows to meet stringent latency requirements, ensuring punctual IP packet delivery within specific time windows. To this end, the guaranteed Latency Based Forwarding (gLBF) approach features per-hop bounded delays to meet the target latency requirements of data flows based on end-to-end application needs. This article introduces a Prolog-based specification of gLBF for path selection and delay configuration. Our prototype determines paths and delays to meet data flow latency targets, offering a concise and extendable solution to the considered problem. We illustrate the scalability of our approach on real and random network topologies, with up to 1000 nodes and flows to be placed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
