 This paper studies the performance and feasibility of several QoS mechanisms in single-homed and multi-homed networks slash nodes with fluctuating resource availability, introducing an interface selectivity technique to enhance essential governing parameters such as throughput, latency, processing time, and jitter. The results show that site multi-homing provides a better overall end-to-end latency over host multi-homing as it supports the entire network.
