【摘要】 本文提出了一个两层的可靠性模型:可靠P/S协议层(RPSL)和可靠流传输层(RSTL)。RPSL理解发布/订阅的消息格式,提供尽力传递、事件丢失检测与恢复、有确认传递等多种可靠性;RSTL不理解发布/订阅的消息格式,通过链路速率自适应、断点续传等机制保证事件传递的可靠。更多还原

【Abstract】 We suppose a two-layer reliability model, which contains the reliable P/S protocol layer (RPSL) and the reliable stream transfer layer (RSTL).RPSL is aware of the format of P/S messages,and provides several reliability levels, which are the best-effort transfer,the event-loss detection and recovery, and the ack-transfer.RSTL is not concerned with the format of RPSL messages, which guarantees that events can be reliably forwarded through the mechanisms of adaptation to link rates and break-and-renewal.更多还原
