中央控制基于预约的带宽分配算法是APON的首选，它具有良好的时延和吞吐量特性。
Centrally controlled reservation-based bandwidth allocation algorithm is the first choice for APON, because it ensures better delay and throughput.
除了提供更高的带宽外，主要的解决技术集中在设计合理的体系结构、资源预约、接入控制技术、排队算法等方向。
Except getting more bandwidth, the most solutions focus on design a reasonable architecture, resource reservation, access control, queueing algorithms and so on.
在IEEE 802.16无线城域网中，基于带宽请求消息的预约协议在高ip业务负载时易导致预约冲突。
Reservation protocols based on bandwidth request messages are prone to collisions during heavy IP traffic load in IEEE 802.16 wireless metropolitan area networks.
