在NGN中支持流状态感知传输技术方面的要求 |
ITU-T Y.2121建议书对下一代网络(NGN)支持流状态认识(FSA)传送能力的要求做了详细说明。FSA传输能力提供按每流操作的QoS控制,使流根据信令参数接受不同处理。采用带内信令需要这些参数。这些信号中包括的参数被纳入每个FSA节点的各流维持的“流状态”。可选的服务选项包括对最高可用性的端到端(或FSA边到边)数据传输速率的必要支持。另一选项是立即传输,在了解到网络需要尽快提供有保障速率后,流可能立即启动或采用新的速率。这是在网络资源允许情况下必须提供的。而还有一个选项是谈判达成的保证速率。这些服务成为接入情境的目标,此时的媒体流可能造成短时拥塞,而靠尽力而为不能有选择地对引发拥塞的最后几个流采取行动。这些服务也可用于流的总和,从而可能在总和端点和支持与每流控制共同作用的直接汇集速率变化选项之间提供最高的可用速率。 |
