Summary

Supplement 61 to Recommendation ITU-T G.1020 documents a packet-oriented Internet protocol (IP)-centric quality of service (QoS) management model. This model is applicable to a wireless access point (e.g., Wi-Fi AP, evolved Node B (eNode B), Node B), referred to as an IP aware access point. The Supplement describes a possible cross-layer design for this model in long-term evolution/evolved packet core (LTE/EPC) networks. Some implementation challenges are highlighted, together with possible solutions implying only minor modifications in the eNode B. Performance of this proposal compared to various implementations of the third generation partnership project (3GPP) QoS model is evaluated using the network simulator-3 (ns-3) in realistic scenarios.
