Next Generation Network (NGN) is a packet based network which can support the expansion of broadband and introduction of triple play (Voice +Data +Video) over fixed and mobile line. Before deployment of NGN, the capacity and Quality of Service (QoS) over NGN must be ensured. In this paper, the technologies proposed by Huawei have been applied to ensure the capacity and QoS over NGN. Then the optimized...
A new subfunction for the IEEE 802.11e EDCF allowing efficient transport of real-time traffic is proposed. The delay induced by the freezout of the backoff counter is to be considered. Intentional dropping is used if a certain threshold delay is exceeded. A system enabled with this suggested feature is analyzed and the impact of backoff parameters on the transmission probability, the dropping probability,...
