Provisionamento de QoS em NDN através da diferenciação de serviços e gerenciamento de cache.

Abstract

Named Data Networks (NDN) decouple data from its location through exclusive naming and operate on a best-effort model, limiting support for applications that require Quality of Service (QoS). The NDN cache expands manageable resources, but traditional cache policies do not meet QoS requirements. This work presents the DSPPC policy, which considers data popularity and its service class in cache management, along with a QoS encoding mechanism in packet names. Simulations demonstrate that the DSPPC proposal keeps priority data in the cache without compromising less-prioritized data, compared to the evaluated cache policies.
